Description

Technical Field

[0001] This invention relates to the field of coating, and more specifically to a coating method for multi-colored travertine decoration. Background Technology

[0002] Natural stone is highly favored in the field of architectural decoration due to its beautiful patterns. However, due to its high price, most decoration projects currently use imitation natural stone patterns to achieve decorative effects in order to reduce costs. In travertine simulation decoration, textured effects are usually required to improve the simulation effect. However, existing coating methods do not produce a high degree of simulation and the decorative effect is not good. Summary of the Invention

[0003] The present invention aims to provide a coating application method for multi-colored travertine decoration to improve the decorative effect and simulation of the wall surface.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a method for applying a coating to multi-colored travertine decoration, comprising the following steps:

[0005] Step 1: Wall pretreatment. First, clean the wall surface to ensure that the base layer is flat. Use a scraper to evenly apply crack-resistant mortar to the wall surface, then apply paint putty to level it, and finally evenly apply environmentally friendly primer to form a base coat.

[0006] Step 2: Mix the travertine base material and the travertine surface material separately. Apply a layer of travertine base material to the prepared base layer, then apply a thin layer of travertine surface material. After it dries completely, apply a thin layer of travertine surface material.

[0007] Step 3: When the second layer of travertine fabric is half dry, hold a scraping tool and slide it on the surface of the fabric to create a textured pattern. Press it flat and use a painting tool to intermittently apply travertine topcoat to the surface of the fabric.

[0008] Step 4: Finally, spray a clear topcoat to increase the gloss of the decorative effect and protect the wall surface.

[0009] The principle and advantages of this solution are as follows: The coating method in this solution effectively improves the decorative effect and enhances the realism of the decoration. The wall pretreatment in this solution provides a suitable working surface. First, the surface is cleaned of dust and debris to ensure a clean and tidy state. Then, crack-resistant mortar is applied, which not only provides crack resistance but also levels the base layer. Applying putty provides micro-leveling and localized leveling, making the wall surface smoother. Applying paint putty further levels the surface, facilitating subsequent construction and improving the smoothness of the coated wall, thereby improving the overall coating quality and decorative effect. Finally, an environmentally friendly primer is evenly applied to form a base coat. This primer layer separates the subsequent travertine layer, preventing alkaline substances in the cement from leaching out and reacting with the travertine layer, causing color changes. Furthermore, the primer layer provides better adhesion for the base coat, facilitating subsequent construction.

[0010] This solution uses a base coat to create a base color, providing a foundation for more realistic color development and facilitating the application of textured effects later. A layer of travertine base coat is applied to the prepared base, followed by a thin layer of travertine fabric. When the second layer of travertine fabric is semi-dry, a textured scraper is used to create the texture. A flat topcoat is then applied to achieve the desired effect. Since the first layer of travertine fabric is completely dry, the textured effect is not visible through the second layer, preventing the base color from showing through. This results in a better, more realistic, and more visually appealing wall decoration, enhancing the overall aesthetics and decoration. Finally, a clear topcoat is sprayed on to increase the gloss and protect the wall surface.

[0011] Preferably, as an improvement, the travertine base material, by weight parts, includes: 90-130 parts water, 1-2 parts pH adjuster, 1-2 parts wetting agent, 3-6 parts dispersant, 1-2 parts defoamer, 10-20 parts antifreeze co-solvent, 5-8 parts film-forming aid, 3-5 parts preservative, 120-150 parts emulsion, 20-40 parts pigment, 600-650 parts quartz sand, 2-3 parts cellulose, 3-5 parts bentonite, and 3-6 parts thickener.

[0012] The beneficial effects are as follows: Adjusting the pH value of the coating helps improve its stability and adhesion; a suitable pH value helps ensure compatibility between the coating and the substrate, reducing the occurrence of adverse reactions. Defoamers prevent air bubbles from forming during preparation and application, ensuring a smooth coating surface and improving the appearance quality of the coating. The emulsion, as the base of the coating, provides the basic properties of the coating and enhances its adhesion. Quartz sand, cellulose, and bentonite help provide the texture and grain of the coating, increasing its three-dimensionality and textural effect. Thickeners increase the viscosity of the coating, helping to improve vertical adhesion, preventing dripping on vertical surfaces, and improving ease of application. The product formula, obtained through creative work by the inventors in practical application, uses a primer that serves to apply a layer of base color. The primer prepared using this formula is a sand-containing product with a certain thickness and good hiding power, thus preventing uneven coloring and show-through.

[0013] Preferably, as an improvement, the travertine topcoat, by weight, comprises 90-120 parts water, 1-2 parts pH adjuster, 3-5 parts wetting agent, 15-18 parts dispersant, 5-8 parts defoamer, 15-18 parts antifreeze co-solvent, 18-25 parts film-forming aid, 3-5 parts preservative, 3-5 parts bactericide, 300-350 parts emulsion, 150-180 parts pigment, 300-350 parts filler, 3-5 parts cellulose, and 3-6 parts thickener.

[0014] The beneficial effects are: the topcoat produced using this technical solution has good hiding power, and can be applied and shaped in one coat when applying the topcoat color.

[0015] Preferably, as an improvement, the travertine fabric, by weight, comprises 150-200 parts water, 1-2 parts pH adjuster, 10-20 parts antifreeze co-solvent, 5-8 parts film-forming aid, 1-2 parts defoamer, 2-3 parts preservative, 2-3 parts bactericidal varnish, 120-150 parts emulsion, 700-800 parts quartz sand, 2-3 parts cellulose, 2-3 parts bentonite, and 3-6 parts thickener.

[0016] The beneficial effects are: quartz sand, cellulose and bentonite help to provide the texture and grain of the coating, increase the three-dimensionality and texture of the coating, and the fabric in this solution does not completely cover the substrate, with appropriate coverage, so that the textured effect is better.

[0017] Preferably, as an improvement, 150-200 parts (to be further confirmed with the customer) of colored sand are added to the travertine fabric.

[0018] The beneficial effects are as follows: the addition of colored sand can add unique colors and textures to the paint, making the paint surface more colorful; colored sand achieves a semi-transparent feel, enhancing the main decorative effect; after adding colored sand, a fine granular texture is formed on the wall surface, giving it a semi-transparent effect, increasing the texture and layering of the wall surface, creating a more three-dimensional decorative effect, and making the wall surface more profound; the granular texture of colored sand helps to simulate the appearance of natural stone, especially under sunlight, it may show a translucent effect, enhancing the simulation and making the wall surface closer to the appearance of natural stone.

[0019] Preferably, as an improvement, 80-100 parts (to be further confirmed with the customer) of expanded perlite are added to the travertine fabric.

[0020] The beneficial effects are as follows: Expanded perlite has the characteristics of being lightweight and porous, which can increase the flexibility of the coating. When added to the coating, it can make the coating more elastic, reduce the risk of cracking under external pressure, and at the same time, it can achieve a thickness of 5mm in one coat without cracking during the application process by the operator, improve the brushing performance, and make the construction smoother and more efficient.

[0021] Preferably, as an improvement, the scraping tool includes a mounting plate and a handle fixed to the bottom of the mounting plate. The mounting plate has a scraping tooth unit and a pressure unit at both ends. The pressure unit includes a bracket, a rotating shaft, and a pressure roller. The pressure roller is sleeved on the rotating shaft, which is rotatably connected to the bracket. The bracket is detachably connected to the mounting plate. The scraping tooth unit includes a scraping tooth disc and a transmission unit. The scraping tooth disc includes an inner disc and an annular disc disposed outside the inner disc. The annular disc and the inner disc are rotatably connected by bearings. Both the annular disc and the inner disc have a plurality of scraping teeth arrayed on them. An annular gear is fixed to the bottom of the annular disc. A worm gear is sleeved on the rotating shaft. The transmission unit meshes with the worm gear and the annular gear on both sides, respectively. When the rotating shaft rotates, it can drive the annular disc to rotate.

[0022] The beneficial effects are as follows: Through the above settings, the scraper teeth can scrape out textured patterns on the wall surface. The pressure roller can rotate due to friction during movement. After the scraper teeth scrape out the textured patterns, it can be pressed down in time, thus making the wall surface smooth and avoiding scraping off excess material during the process of scraping the textured patterns, which would affect the aesthetics of the wall surface. While the pressure roller rotates, it can drive the annular disc to rotate through the transmission unit. The pressure roller is sleeved on the rotating shaft and can rotate during movement. Through the above settings, texture processing can be performed during the pressing process. Several scraper teeth are arrayed on the inner disc and the annular disc, which helps to form diverse textured patterns, making the wall surface more layered and unique. During the rotation of the annular disc, it can produce relatively messy and irregular curved patterns with relatively beautiful lines.

[0023] Preferably, as an improvement, the annular disk has a plurality of first scraping teeth and second scraping teeth arranged in an array, the first scraping teeth and second scraping teeth being arranged alternately, and the distance between the first scraping teeth and the inner disk is greater than the distance between the second scraping teeth and the inner disk, and the length of the first scraping teeth is greater than the length of the second scraping teeth; it also includes a connecting pipe, the inner disk being fixed to the mounting plate through the connecting pipe, the surface of the inner disk having ventilation holes, and the mounting plate having a hot air section embedded therein, the hot air section communicating with the ventilation holes.

[0024] The beneficial effects are as follows: By setting the first and second scraper teeth as described above, the length of the first scraper tooth is greater than that of the second scraper tooth, allowing for the simultaneous creation of curves of varying depths. The difference in length and the spacing between the first and second scraper teeth enable the simultaneous creation of curves of varying depths in a single application. This design better matches the natural texture distribution of travertine slabs in the natural environment, increasing the layering of the decorative effect. Simultaneously, the distance between the first scraper tooth and the inner plate is greater than the distance between the second scraper tooth and the inner plate, producing more random curves. This helps simulate the natural texture of travertine slabs, enhancing the visual appeal and making the wall decoration more artistic. The inclusion of a hot air section allows hot air to blow across the surface of the travertine slab, removing excess powder scraped off by the scraper teeth and accelerating the drying process, improving construction efficiency and promoting rapid drying of the wall surface after application. Ventilation holes are provided on the surface of the inner plate, ensuring that hot air fully covers the surface of the travertine slab and is evenly distributed throughout the application area.

[0025] Preferably, as an improvement, after applying the primer in the first step, two layers of tape are applied to the wall at intervals; then, in the second step, the travertine base coat is applied, and one layer of tape is removed to proceed with the subsequent steps; in the third step, after the travertine topcoat dries, the second layer of tape is removed.

[0026] The beneficial effects are as follows: After applying the primer in this solution, the tape applied to the wall surface will create a seam effect on the wall surface after the tape is removed later. This seam has a certain thickness and looks more like the effect of spliced ​​stone, resulting in a better stone simulation effect and thus enhancing the decorative effect.

[0027] Furthermore, this solution uses a two-layer tape structure, which is removed in two stages during actual construction. The advantage of this is that, since a base coat and top coat are applied during construction, the entire paint layer has a certain thickness. If the tape is removed all at once after the textured surface is created, the thick paint layer makes removal difficult and results in noticeable rough edges, affecting the decorative effect. This solution, by removing the tape in two stages, reduces the thickness of the paint layer corresponding to each tape layer, effectively minimizing rough edges and achieving a better decorative effect.

[0028] Preferably, as an improvement, after the primer dries in the first step, dividing strips are pasted onto the primer surface. The dividing strips are 2cm wide and 5mm thick. After the third step is completed, the dividing strips are removed before proceeding to the fourth step.

[0029] The beneficial effects are as follows: With the above settings, after the dividing strips are removed later, a joint effect can be formed on the wall surface, which has a certain thickness and looks more like the effect of stone being spliced ​​together. The stone simulation effect is better, thereby enhancing the decorative effect. At the same time, the dividing strips are easier and more efficient to operate than tape. Attached Figure Description

[0035] The following detailed description illustrates the specific implementation method:

[0036] The reference numerals in the accompanying drawings include: mounting plate 1, handle 2, bracket 3, rotating shaft 4, pressure roller 5, inner disc 6, annular disc 7, central scraper tooth 8, ring gear 9, worm 10, worm wheel 11, intermediate gear 12, first rotating shaft 13, second rotating shaft 14, first scraper tooth 15, second scraper tooth 1, connecting pipe 17, ventilation hole 18, strip plate 19, fixing plate 20, screw 21, butterfly locking buckle 22, strip groove 23, and limiting groove 24.

[0037] Example 1

[0038] A method for applying a multi-colored travertine decorative coating includes the following steps: Step 1: Wall pretreatment. First, clean the wall surface to ensure that the base layer is flat. Use a scraper to evenly apply crack-resistant mortar to the wall surface. Then, apply paint putty to level the surface. Finally, evenly apply an environmentally friendly primer to form a primer layer.

[0039] Step 2: Mix the travertine base material and the travertine surface material separately. Apply a layer of travertine base material to the prepared base layer, then apply a thin layer of travertine surface material. After it dries completely, apply a thin layer of travertine surface material.

[0040] The travertine base material, by weight, comprises: 90-130 parts water, 1-2 parts pH adjuster, 1-2 parts wetting agent, 3-6 parts dispersant, 1-2 parts defoamer, 10-20 parts antifreeze co-solvent, 5-8 parts film-forming aid, 3-5 parts preservative, 120-150 parts emulsion, 20-40 parts pigment, 600-650 parts quartz sand, 2-3 parts cellulose, 3-5 parts bentonite, and 3-6 parts thickener. In this embodiment, the travertine base material, by weight, comprises: 90 parts water, 1 part pH adjuster, 1 part wetting agent, 3 parts dispersant, 1 part defoamer, 12 parts antifreeze co-solvent, 6 parts film-forming aid, 3 parts preservative, 120 parts emulsion, 20 parts pigment, 600 parts quartz sand, 2 parts cellulose, 3 parts bentonite, and 3 parts thickener.

[0041] Adjusting the pH value of the coating helps improve its stability and adhesion. A suitable pH value helps ensure compatibility between the coating and the substrate, reducing the occurrence of adverse reactions. Defoamers prevent air bubbles from forming during preparation and application, ensuring a smooth coating surface and improving the appearance quality of the paint. Emulsions, as the base of the coating, provide the basic properties of the coating and enhance its adhesion. Quartz sand, cellulose, and bentonite help provide the texture and grain of the coating, increasing its three-dimensionality and textural effect. Thickeners increase the viscosity of the coating, helping to improve vertical adhesion, preventing dripping on vertical surfaces, and improving ease of application. The product formula, obtained through creative work by the inventors in practical application, uses a primer that serves to apply a layer of base color. The primer prepared using this formula is a sand-containing product with a certain thickness and good hiding power, thus preventing uneven coloring and show-through.

[0042] The travertine fabric, by weight, comprises 150-200 parts water, 1-2 parts pH adjuster, 10-20 parts antifreeze co-solvent, 5-8 parts film-forming aid, 1-2 parts defoamer, 2-3 parts preservative, 2-3 parts bactericidal varnish, 120-150 parts emulsion, 700-800 parts quartz sand, 2-3 parts cellulose, 2-3 parts bentonite, and 3-6 parts thickener. In this embodiment, the travertine fabric, by weight, comprises 150 parts water, 1 part pH adjuster, 10 parts antifreeze co-solvent, 5 parts film-forming aid, 1 part defoamer, 2 parts preservative, 2 parts bactericidal varnish, 120 parts emulsion, 700 parts quartz sand, 2 parts cellulose, 3 parts bentonite, and 6 parts thickener. The quartz sand, cellulose, and bentonite in this fabric help to provide texture and grain to the coating, increasing its three-dimensionality and textural effect. The fabric in this solution does not completely cover the substrate, providing appropriate coverage for better textured effects.

[0043] Step 3: When the second layer of travertine fabric is semi-dry, use a hand scraping tool to glide across the fabric surface to create a textured pattern, press it flat, and then use a painting tool to intermittently apply travertine topcoat to the fabric surface. The travertine topcoat, by weight, includes 90-120 parts water, 1-2 parts pH adjuster, 3-5 parts wetting agent, 15-18 parts dispersant, 5-8 parts defoamer, 15-18 parts antifreeze co-solvent, 18-25 parts film-forming aid, 3-5 parts preservative, 3-5 parts bactericide, 300-350 parts emulsion, 150-180 parts pigment, 300-350 parts filler, 3-5 parts cellulose, and 3-6 parts thickener. In this embodiment, the travertine topcoat, by weight, comprises 90 parts water, 1 part pH adjuster, 3 parts wetting agent, 15 parts dispersant, 5 parts defoamer, 15 parts antifreeze co-solvent, 18 parts film-forming aid, 3 parts preservative, 3 parts bactericide, 300 parts emulsion, 150 parts pigment, 300 parts filler, 3 parts cellulose, and 3 parts thickener. The flat-coat topcoat produced using this technical solution has good hiding power and can be applied and shaped in one coat during surface coloring.

[0044] like Figure 1 and Figure 2 As shown, the scraping tool in this embodiment includes a mounting plate 1 and a handle 2 fixed to the bottom of the mounting plate 1. The mounting plate 1 has a scraping tooth unit and a pressing unit at both ends, as shown... Figure 3As shown, the pressing unit includes a bracket 3, a rotating shaft 4, and a pressure roller 5. The pressure roller 5 is sleeved on the rotating shaft 4 and fixed to the rotating shaft 4. The rotating shaft 4 is rotatably connected to the bracket 3, and the bracket 3 is detachably connected to the mounting plate 1. The scraping unit includes a scraping disc and a transmission part. The scraping disc includes an inner disc 6 and an annular disc 7 disposed outside the inner disc 6. The annular disc 7 and the inner disc 6 are rotatably connected by bearings. Both the annular disc 7 and the inner disc 6 are arrayed with several scraping teeth. An annular gear 9 is fixed to the bottom of the annular disc 7. A worm gear 10 is sleeved on and fixed to the rotating shaft 4. The two sides of the transmission part are respectively connected to the worm gear 10. The rod 10 engages with the ring gear 9, and the rotation of the rotating shaft 4 drives the ring disk 7 to rotate. Specifically, the transmission part includes a worm gear 11 and an intermediate gear 12. The mounting plate 1 is fixed with a first rotating shaft 13 and a second rotating shaft 14. Both the first rotating shaft 13 and the second rotating shaft 14 are rotatably connected to rotating rings through bearings. The worm gear 11 and the intermediate gear 12 are respectively keyed to the rotating rings on the first rotating shaft 13 and the second rotating shaft 14. The worm gear 11 meshes with the worm 10 and the intermediate gear 12, and the intermediate gear 12 also meshes with the ring gear 9. When the pressure roller 5 rotates, it drives the ring disk 7 to rotate through the transmission part. The pressure roller 5 is sleeved on the rotating shaft 4 and can rotate during movement. Through the above settings, texture processing can be performed during the pressing process. Multiple central scraping teeth 8 are arrayed on the inner disk 6, which helps to form diverse textures and make the wall surface more layered and unique. When the ring disk 7 moves and rotates, it can produce relatively messy and irregular curved textures with beautiful lines.

[0045] The annular disc 7 has several first scraping teeth 15 and second scraping teeth 16 arranged in a series of intervals. The distance between the first scraping teeth 15 and the inner disc 6 is greater than the distance between the second scraping teeth 16 and the inner disc 6. The length of the first scraping teeth 15 is greater than the length of the second scraping teeth 16. The greater length of the first scraping teeth 15 and the second scraping teeth 16 allows for the simultaneous scraping of curves of varying depths. The difference in length and the interval between the first scraping teeth 15 and the second scraping teeth 16 enable the simultaneous scraping of multiple curves of varying depths in one application, which better matches the texture distribution of the karst slab in the natural environment and increases the sense of layering in the decorative effect. Meanwhile, the distance between the first scraper tooth 15 and the inner plate 6 is greater than the distance between the second scraper tooth 16 and the inner plate 6, which can produce more random curved lines. This helps to simulate the natural texture of natural travertine slabs, enhances the visual appeal, and makes the wall decoration more artistic. It also includes a connecting pipe 17, through which the inner plate 6 is fixed to the mounting plate 1. Ventilation holes 18 are opened on the surface of the inner plate 6, and a hot air unit is embedded in the mounting plate 1, communicating with the ventilation holes 18. By setting up the hot air unit, hot air blows onto the surface of the travertine fabric, removing excess powder scraped off by the scraper teeth, and simultaneously helping to accelerate the drying process of the travertine fabric surface, improving construction efficiency and promoting rapid drying of the wall surface after scraping. Ventilation holes 18 are opened on the surface of the inner plate 6 in the center. These ventilation holes 18 allow hot air to fully cover the surface of the travertine fabric, ensuring that the hot air can be evenly blown across the entire scraping area.

[0046] In this embodiment, the painting tools include a brush roller and a rubbing roller. The rubbing roller has a horizontal array of arc-shaped stripes on its surface, with the density of the arc-shaped stripes on one side of the roller being greater than that on the other. By performing intermittent rubbing, that is, the application of the rubbing roller on the wall is discontinuous rather than continuous, a more realistic and natural rubbing effect can be simulated. This design makes the color changes in the coating more organic and irregular, more in line with the texture distribution of natural materials. The horizontal array of arc-shaped stripes gives the rubbing roller a unique texture structure, simulating the texture of some natural material surfaces, making the rubbing effect more realistic.

[0047] Step 4: Finally, spray a clear topcoat to increase the gloss of the decorative effect and protect the wall surface.

[0048] The principle and advantages of this solution are as follows: The coating method in this solution effectively improves the decorative effect and enhances the realism of the decoration. The wall pretreatment in this solution provides a suitable working surface. First, the surface is cleaned of dust and debris to ensure a clean and tidy state. Then, crack-resistant mortar is applied, which not only provides crack resistance but also levels the base layer. Applying putty provides micro-leveling and localized leveling, making the wall surface smoother. Applying paint putty further levels the surface, facilitating subsequent construction and improving the smoothness of the coated wall, thereby improving the overall coating quality and decorative effect. Finally, an environmentally friendly primer is evenly applied to form a base coat. This primer layer separates the subsequent travertine layer, preventing alkaline substances in the cement from leaching out and reacting with the travertine layer, causing color changes. Furthermore, the primer layer provides better adhesion for the base coat, facilitating subsequent construction.

[0049] This solution uses a base coat to create a base color, providing a foundation for more realistic color development and facilitating the application of textured effects later. A layer of travertine base coat is applied to the prepared base, followed by a thin layer of travertine fabric. When the second layer of travertine fabric is semi-dry, a textured scraper is used to create the texture. A flat topcoat is then applied to achieve the desired effect. Since the first layer of travertine fabric is completely dry, the textured effect is not visible through the second layer, preventing the base color from showing through. This results in a better, more realistic, and more visually appealing wall decoration, enhancing the overall aesthetics and decoration. Finally, a clear topcoat is sprayed on to increase the gloss and protect the wall surface.

[0050] Example 2

[0051] The difference between this embodiment and Embodiment 1 is that 150-200 parts of colored sand are added to the travertine fabric, while 180 parts are added in this embodiment.

[0052] Adding colored sand can give paint unique colors and textures, making the paint surface more colorful; colored sand achieves a semi-transparent feel, enhancing the main decorative effect; after adding colored sand, it forms a fine granular texture on the wall surface, giving it a semi-transparent effect, increasing the texture and layering of the wall surface, creating a more three-dimensional decorative effect, and making the wall surface more profound; the granular texture of colored sand helps to simulate the appearance of natural stone, especially under sunlight it may show a translucent effect, enhancing the simulation and making the wall surface closer to the appearance of natural stone.

[0053] Example 3

[0054] The difference between Example 3 and Example 1 is that 80-100 parts of expanded perlite were added to the travertine fabric; in this example, 80 parts were added. Expanded perlite is lightweight and porous, which increases the flexibility of the coating. When added to the coating, it makes the coating more elastic, reducing the risk of cracking under external pressure. Furthermore, during the application process, it allows for a 5mm thick coat without cracking, improving brushing performance and making construction smoother and more efficient.

[0055] The coated wall surface prepared according to the coating method and travertine coating formula in Example 3 was inspected and tested. Figure 5 As shown, the score is based on appearance, with a maximum score of 10 points. The inspection criteria include whether there are gaps in the texture, whether the wall surface is flat, and the coloring and molding effect.

[0056]

[0057] The painted wall surface produced using the above method and the Mitangstone paint formula has good flatness. After the above coating steps are used to level the wall surface, it is easier to carry out subsequent construction operations, making the subsequent application of Mitangstone primer, surface material and flat topcoat smoother.

[0058] The primer and special coating are sand-textured paints, which contain sand. The flat topcoat is a sand-free product, which is a latex paint and a thin-coat material. In this solution, the primer is used to create the base color. The primer prepared using the formula in this solution is a sand-textured product with a certain thickness and good hiding power, which can prevent the appearance of uneven coloring or the base coat showing through.

[0059] The coating on the fabric facilitates the creation of textured effects as needed. In existing techniques, when creating textured patterns, gaps often appear after the texture is scraped away, revealing the underlying base color and affecting aesthetics. Furthermore, this method makes it easier to achieve the desired textured effect, and the fabric in this solution does not completely cover the substrate, providing appropriate coverage for a superior textured finish.

[0060] By applying a base coat followed by a top coat, and then allowing the top coat to dry to about 70% before applying the texture, a two-layer coating effect is achieved on the travertine decorative material. When using a scraper to create the texture, gaps are minimized, preventing the base color from showing through and thus improving the overall decorative effect and aesthetics of the wall. The flat topcoat prepared using the formula in this solution has good hiding power and can be applied in one coat. This ability to apply the color evenly results in a better decorative effect on the finished wall.

[0061] Example 4

[0062] The difference between Example 4 and Example 1 is that, in the first step, after applying the primer, two layers of tape are pasted alternately on the wall; in the second step, the travertine base coat is applied, and one layer of tape is removed before proceeding to the next step; in the third step, after the travertine topcoat dries, the second layer of tape is removed.

[0063] In this design, after applying the primer, masking tape is applied to the wall. This allows the tape to be removed later, creating a seam effect on the wall with a certain thickness, making it look more like pieces of stone being pieced together. This enhances the stone simulation effect and thus improves the decorative effect.

[0064] Furthermore, this solution uses a two-layer tape structure, which is removed in two stages during actual construction. The advantage of this is that, since a base coat and top coat are applied during construction, the entire paint layer has a certain thickness. If the tape is removed all at once after the textured surface is created, the thick paint layer makes removal difficult and results in noticeable rough edges, affecting the decorative effect. This solution, by removing the tape in two stages, reduces the thickness of the paint layer corresponding to each tape layer, effectively minimizing rough edges and achieving a better decorative effect.

[0065] Example 5

[0066] The difference between Example 5 and Example 3 is that after the primer dries in the first step, dividing strips are pasted on the primer surface. The dividing strips are 2cm wide and 5mm thick. After the third step is completed, the dividing strips are removed before proceeding to the fourth step.

[0067] After the dividing strips are removed later, a joint effect is created on the wall surface, with a certain thickness, making it look more like stone pieces being pieced together. The stone simulation effect is better, thus enhancing the decorative effect. At the same time, the dividing strips are easier and more efficient to operate than tape.

[0068] Example 6

[0069] Example 6 is basically as follows Figure 4 As shown, the support 3 in this embodiment includes the following: Figure 4The two L-shaped frames shown support the left and right sides of the pressure roller 5 respectively. The L-shaped frame includes a strip plate 19, a slide rail, and a fixed plate 20. The strip plate 19 is vertically slidably connected to the fixed plate 20 through the slide rail. In this embodiment, the worm gear 11 has a certain length and can continue to be engaged after the worm 10 slides in a vertical position. A locking mechanism is provided between the strip plate 19 and the fixed plate 20. The locking mechanism includes a screw 21 and a butterfly locking buckle 22 threadedly connected to the screw 21. A strip groove 23 is opened on the strip plate 19. The screw 21 passes through the fixed plate 20 and the strip groove 23. The butterfly locking buckle 22 abuts against the side wall of the strip groove 23. A limiting groove 24 is also opened on the surface of the strip plate 19 near the butterfly locking buckle 22. The width of the limiting groove 24 is narrower than the width of the butterfly locking buckle 22, which can limit the butterfly locking buckle 22 and prevent it from loosening during use. In this embodiment, a scale is provided on the strip plate 19, which provides a reference when adjusting the position of the pressure roller 5 and improves the adjustment accuracy.

[0070] During use, adjust the distance between the pressure roller 5 and the end of the scraper teeth according to the construction requirements. When a deeper texture is needed, the distance between the pressure roller 5 and the end of the scraper teeth needs to be increased. After adjustment, rotate the spiral locking buckle 22 to fix the strip plate 19, preventing it from sliding after adjustment to the desired state, thus enabling smooth and stable scraping of texture and pressure reduction operations.

[0071] When a shallower texture is desired, follow the steps outlined above. Simply slide the strip plate 19 in the opposite direction to move the pressure roller 5 away from the fixed plate 20. This increases the distance between the pressure roller 5 and the fixed plate 20, decreasing the distance between the pressure roller 5 and the tip of the scraper teeth. This results in a shallower texture. This allows adjustment of the scraper teeth's insertion depth according to the paint thickness, effectively creating a textured effect while avoiding gaps caused by uneven pressure, inconsistent application techniques, or excessive insertion depth. Such gaps would expose the base coat and affect the overall decorative effect. Through this setup, users can adjust the height of the pressure roller 5 to achieve different texture depths at different locations, creating a undulating effect on the wall surface.
