Abstract
Description
Technical Field
[0001] This invention relates to the field of building construction technology, and in particular to a vertical micro-textured construction process for cement mortar plastering with mesh reinforcement in kitchens and bathrooms. Background Technology
[0002] Currently, in the delivery of unfinished kitchen and bathroom units, the walls are typically finished with cement mortar plaster or have a roughened finish. When homeowners later renovate and need to tile the walls, a common practice is to roughen the plaster surface to enhance adhesion, such as by applying cement slurry, applying dots, or rolling on a bonding agent. Some projects also use wire mesh plastering to prevent hollow areas and cracking.
[0003] However, existing wall treatment methods have significant shortcomings: On the one hand, traditional random roughening or dot-mapping techniques lack layout design, resulting in a messy and disorganized roughened surface with poor visual appeal, failing to meet the aesthetic requirements of quality residential buildings for unfinished delivery; on the other hand, while a rough surface facilitates adhesion, uneven roughening depth and inconsistent direction can easily lead to localized hollow spots during later tile installation, and roughening often requires additional materials (such as interface agents and construction adhesives), increasing construction costs. Furthermore, the lack of standardized treatment for the connection between roughened walls and electrical boxes, window openings, and corners creates inconvenience for homeowners during secondary renovations in terms of positioning and finishing. Summary of the Invention
[0004] The purpose of this invention is to provide a vertical micro-textured construction process for cement mortar plastering with mesh reinforcement in kitchens and bathrooms, which solves the problems of poor visual aesthetics, insufficient tile bonding strength, and lack of uniform layout and finishing standards in the construction of rough walls in kitchens and bathrooms in the existing technology.
[0005] To achieve the above objectives, this invention provides a construction process for vertical micro-textured cement mortar plastering with mesh reinforcement in kitchens and bathrooms, comprising the following steps: Clean the base of the kitchen and bathroom walls, and hang 300mm wide 20×20×0.7mm galvanized steel wire mesh at the junction of masonry and concrete walls; After hanging galvanized steel wire mesh, the wall surface is plastered and mortar spots are applied for sizing. After the mortar has been applied and the mortar spots have been cured for no less than 3 days, cement mortar mesh-attached plastering is carried out to form a cement mortar plaster layer. Before the cement mortar plaster layer has fully set, the rough surface area and the smooth surface dividing strip with a width of 100mm are divided on the wall according to the preset layout drawing. In the textured area, two people work together using a special texturing tool to perform texturing operations in the vertical direction, forming vertical micro-texturing with uniform depth; The smooth surface of the partition zone, the bottom of the beam, the sides of the window opening, and the inside corners of the smoke exhaust duct are polished to maintain the smooth surface. Allow the textured and polished wall surface to cure naturally until it hardens.
[0006] The process of cleaning the base layer of the kitchen and bathroom walls and installing 300mm wide 20×20×0.7mm galvanized steel wire mesh at the junction of the masonry and concrete walls includes: The wire mesh is a hot-dip galvanized steel wire mesh with a diameter of 0.7mm and a grid spacing of 20mm×20mm. The overlap width of the wire mesh is not less than 150mm, and it is fixed to the wall base with anchors.
[0007] Among them, in the construction of plastering and mortar patching on the wall after hanging galvanized steel wire mesh: The allowable deviation of verticality of cement mortar plaster layer is no more than 3mm, the allowable deviation of surface flatness is no more than 3mm, and the thickness of plaster layer is 10-15mm.
[0008] In the process of applying cement mortar and installing mesh plastering after the mortar has been applied and cured for no less than 3 days, the specific steps of the cement mortar and mesh plastering construction include: In the cement mortar plastering area, one layer of mortar is applied as a base coat, and after initial setting, a second layer of mortar is applied according to the positioning of the mortar spots, and a 2m long aluminum alloy prefabricated square tube is used for leveling. 160g / m² full wall covering 2 4×4mm mesh, alkali-resistant fiberglass mesh, with an overlap width of not less than 100mm; The trowel is used to press the alkali-resistant fiberglass mesh into the mortar. The mesh is then repeatedly rubbed, lifted, leveled, and finished on the cement wall surface to form a cement mortar plaster layer.
[0009] The specific steps of dividing the wall surface into a rough surface area and a smooth surface dividing strip with a width of 100mm according to a preset layout drawing before the cement mortar plaster layer has finally set include: Determine the vertical range of the rough surface area. Its lower boundary is 400mm from the ground, and its upper boundary is flush with the bottom edge of the window opening. If there is no window, the upper boundary is 400-450mm from the top plate. The upper and lower boundary lines are closed at the same elevation in a separate kitchen and bathroom. Determine the horizontal boundary of the rough surface area, with its left and right boundaries 100mm from the inside corner of the wall or the end of the wall; Determine the centerline position of the smooth dividing strip. The centerline of the horizontal dividing strip is aligned with the centerline of the pre-embedded power supply box in the wall. The vertical dividing strip divides the rough surface equally on the left and right sides. The rough surface is basically divided into four equal parts on one wall.
[0010] The specific steps involved in using a specialized texturing tool to perform a texturing operation in the vertical direction within the textured area to form vertical micro-textures of uniform depth include: The texturing tool uses a special hard plastic brush with a brush width of 400-500mm and a bristle length of 50mm. With the tool close to the wall, within the rough frame line of the layout drawing, one person positions a vertical aluminum alloy square tube as a ruler, while another person operates the brush to pull it vertically from top to bottom, from the left side of the frame line to the right side in one go, with a texture depth of 1mm. The external corners of the flue or exhaust duct are also divided into sections with textured patterns according to the layout diagram.
[0011] The specific steps for applying a smooth finish to the smooth surface in the partition zone area, the bottom of the beam, the sides of the window opening, and the inside corners of the smoke exhaust duct include: Within 30 minutes after the texturing is completed, use a trowel to perform a secondary calendering process on the smooth dividing zone area; The entire width of the beam bottom is subjected to secondary polishing treatment. The entire area around the window opening is subjected to secondary polishing treatment. A secondary polishing process is performed on the area within 100mm on both sides of the inside corner of the exhaust duct to ensure that the polished surface is consistent with the smooth surface separation zone of the adjacent wall.
[0012] The process of naturally curing the textured and polished wall surface until it hardens is described below. The natural curing period is no less than 7 days. During the curing period, spray water at least twice a day to keep the wall surface moist.
[0013] This includes, after the wall surface has undergone texturing and polishing treatments and is allowed to naturally cure until it hardens, the following: Apply polyurethane waterproof coating to the ground and extend it up to a height of 300mm from the wall surface. The wall surface within this extension range should be smooth. Apply waterproof coating to the walls of the bathroom shower area according to the design requirements. Install the switch panels on the kitchen and bathroom walls directly on the smooth or matte surface.
[0014] This invention discloses a vertical micro-textured construction process for cement mortar plastering with mesh reinforcement in kitchens and bathrooms. By using a pre-designed layout, a rough surface area and a 100mm wide smooth surface dividing strip are defined on the wall, achieving a neat layout of the textured area and avoiding the messy appearance of traditional random full-wall texturing. This significantly improves the visual aesthetics of the rough wall surface. By using uniform vertical micro-texturing with a depth of 1mm within the rough surface area, sufficient bonding strength is ensured for subsequent tile installation, while avoiding the risk of hollow areas caused by uneven texturing depth or chaotic direction. Furthermore, using the original mortar for texturing eliminates the need for additional interface agents or construction adhesives, thus not increasing material costs. By polishing the smooth surface dividing strip, the bottom of beams, the sides of window openings, and the sides of the inside corners of the exhaust duct, and aligning it with the center line of the power box, a clear positioning benchmark and finishing interface are provided for homeowners' secondary renovations, further reducing the difficulty and time required for renovation. Attached Figure Description
[0015] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the accompanying drawings used in the description of the embodiments or the prior art will be briefly introduced below.
[0016] Figure 1 This is a flowchart of the construction process for vertical micro-textured cement mortar plastering with mesh reinforcement in kitchens and bathrooms, based on the present invention. Detailed Implementation
[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0018] Please see Figure 1 , Figure 1 This is a flowchart illustrating the construction process of vertical micro-textured cement mortar plastering with mesh reinforcement in kitchens and bathrooms according to the present invention. The present invention provides a construction process for vertical micro-textured cement mortar plastering with mesh reinforcement in kitchens and bathrooms, comprising the following steps: S1: Clean the base of the kitchen and bathroom walls and hang a 300mm wide 20×20×0.7mm galvanized steel wire mesh at the junction of the masonry and concrete walls.
[0019] Specifically, the wire mesh is a hot-dip galvanized wire mesh with a diameter of 0.7mm and a grid spacing of 20mm×20mm. The overlap width of the wire mesh is not less than 150mm, and it is fixed to the wall base with anchors.
[0020] In this embodiment, when cleaning the base layer, it is necessary to remove floating dust, oil stains and loose particles from the wall surface, and rinse it clean with water. The wire mesh is made of hot-dip galvanized material to effectively prevent rust. The overlap width is not less than 150mm to ensure uniform overall stress. The anchors are arranged in a staggered pattern with a spacing of 300-400mm. After fixing, the wire mesh should be flat and without warping.
[0021] S2: Apply plaster and mortar spots to the wall surface after hanging galvanized steel wire mesh.
[0022] Specifically, the allowable deviation of the verticality of the cement mortar plaster layer is no more than 3mm, the allowable deviation of the surface flatness is no more than 3mm, and the thickness of the plaster layer is 10-15mm.
[0023] In this embodiment, the cement mortar is prepared at a volume ratio of 1:3 (refer to the design specifications), and the consistency is controlled at 70-90 mm. The plastering is done in two coats. The first coat is roughened to a thickness of 5-8 mm, and after initial setting, a second coat is applied, compacted, and leveled, with a total thickness of 10-15 mm. During construction, a 2m straightedge is used to check the flatness and verticality, and the deviation is controlled within 3 mm.
[0024] S3: After the mortar has been applied and the mortar spots have been cured for no less than 3 days, cement mortar mesh (alkali-resistant fiberglass mesh) plastering construction will be carried out to form a cement mortar plaster layer.
[0025] Specifically, S31: In the cement mortar plastering area, apply one layer of mortar as a base coat, and after initial setting, apply a second layer of mortar according to the positioning of the mortar spots, and use a 2m long aluminum alloy prefabricated square tube for leveling. S32: 160g / m² for full wall covering 2 4×4mm mesh, alkali-resistant fiberglass mesh, with an overlap width of not less than 100mm; S33: Use a trowel to press the alkali-resistant fiberglass mesh into the mortar, and repeatedly rub, lift, level, and finish the cement wall surface after the mesh is attached to form a cement mortar plaster layer.
[0026] S4: Before the cement mortar plaster layer has set, mark the rough surface area and the smooth surface dividing strip with a width of 100mm on the wall according to the preset layout.
[0027] Specifically, S41: Determine the vertical range of the rough surface area, with its lower boundary 400mm from the ground and its upper boundary flush with the bottom edge of the window opening. If there is no window, the upper boundary is 400-450mm from the top plate. S42: Determine the horizontal boundary of the rough surface area, with its left and right boundaries 100mm from the inside corner of the wall or the end of the wall; S43: Determine the centerline position of the smooth dividing strip. The horizontal dividing strip should be positioned so that the centerline of the smooth dividing strip located in the middle of the wall coincides with the centerline of the pre-embedded power box in the wall. The vertical dividing strip should be positioned so that the left and right rough surfaces are evenly divided. The rough surfaces are basically divided into four equal parts on one wall.
[0028] In this embodiment, the layout diagram is drawn in advance based on the actual dimensions of the wall and the locations of the power boxes. A laser level and measuring tape are used for marking, ensuring that the top and bottom boundaries of the rough surface area are horizontal and the left and right boundaries are vertical. If there are multiple power boxes on the wall, the center box is used as a reference to align with the center line of the smooth surface divider, with a deviation not exceeding 5mm.
[0029] S5: In the textured area, two people work together using a special texturing tool to perform texturing operations in the vertical direction to form vertical micro-texturing with uniform depth.
[0030] Specifically, S51: A textured tool using a special hard plastic brush, with a brush width of 400-500mm and a bristle length of 50mm; S52: Place the tool close to the wall. Within the rough frame line of the layout drawing, one person positions a vertical aluminum alloy square tube as a ruler, while another person operates the brush to pull it vertically from top to bottom, from the left side of the frame line to the right side in one go, with a texture depth of 1mm. S53: The external corner of the flue or exhaust duct shall also be divided into sections and textured according to the layout diagram.
[0031] In this embodiment, a commonly available hard plastic brush can be used as the texturing tool. Before texturing, ensure that the plaster layer surface has absorbed water, has no free water but has not yet hardened. During the texturing process, keep the tool perpendicular to the wall and apply even pressure. The overlap width between adjacent strokes should be controlled between 1 and 3 mm. At the external corners of the exhaust duct, a small tool or manual texturing can be used to ensure that there are textures on both sides of the external corner.
[0032] S6: Apply a smooth finish to the smooth surface of the dividing zone, the bottom of the beam, the sides of the window opening, and the inside corners of the smoke exhaust duct to maintain the smooth surface.
[0033] Specifically, S61: Within 30 minutes after the texturing is completed, use a trowel to perform a secondary calendering process on the smooth surface dividing zone area; S62: Perform full-area secondary polishing treatment on the bottom width of the beam; S63: Perform full-area secondary polishing treatment on all sides of the window opening; S64: Perform secondary polishing treatment on the 100mm range on both sides of the inside corner of the exhaust duct to make the polished surface consistent with the smooth separation zone of the adjacent wall.
[0034] In this embodiment, troweling too early will damage the textured surface, while troweling too late will prevent it from being applied. Therefore, troweling should be performed within 30 minutes after the textured surface is completed, when the plaster layer can be pressed by hand and leaves a slight imprint but does not stick to the trowel. The trowel should be clean and rust-free. When troweling, first smooth the surface horizontally, then finish it vertically. Each troweling overlap should be no less than 50mm, until a uniform mirror-like gloss appears on the surface.
[0035] S7: Allow the textured and polished wall surface to cure naturally until it hardens.
[0036] Specifically, the natural curing time should be no less than 7 days, and the wall surface should be sprayed with water at least twice a day during the curing period to keep it moist.
[0037] In this embodiment, the wall surface should be protected from impact, vibration, or direct sunlight during natural curing. If the ambient temperature is below 5°C, insulation measures should be taken, and the curing time should be extended to 14 days.
[0038] S8: Apply polyurethane waterproof coating to the ground and extend it up to a height of 300mm from the wall surface. The wall surface within this extension range should be smooth. Apply waterproof coating to the walls of the bathroom shower area as required by the design. Install the switch panels on the kitchen and bathroom walls directly on the smooth or matte surface.
[0039] In this embodiment, before applying the polyurethane waterproof coating, the ground and upper wall surfaces must be cleaned of dust. First, apply a primer, then apply two coats of topcoat, with the second coat applied perpendicular to the first. The waterproof height in the shower area is typically 2000mm, depending on design requirements. When installing switch panels, the gap between the panel and the wall should be filled with white or matching sealant; do not use putty or dark paint to maintain the overall simplicity of the wall surface.
[0040] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
