Apply the plaster evenly to the primer layer and let it stand for the second preset time until the plaster dries and forms a brick-like mortar layer. Apply a topcoat agent to the surface of the imitation red brick mortar layer.

[0005] In an embodiment of the present invention, the step of determining the mortar formula through experiments includes: White cement, heavy calcium carbonate powder, quartz sand, and additives were selected as the mortar formula, and the proportions of each component in the mortar were adjusted. Performance tests were conducted on each group of mortars with different component ratios to ensure that the initial crack resistance, strength properties, and workability of the mortars all met the preset requirements. The mortar formula that meets the performance test requirements will be used as the mortar for imitation red brick paving.

[0010] In embodiments of the present invention, the particle size range of the quartz sand is 0 mm to 1.18 mm.

[0011] In an embodiment of the present invention, after the step of applying primer by roller to a predetermined area of ​​the wall and allowing it to stand for a first predetermined time until the primer dries and forms a primer layer, the method further includes: Apply multiple joint strips at equal intervals to the primer layer.

[0012] In an embodiment of the present invention, after the step of uniformly applying the plaster to be painted onto the primer layer and allowing it to stand for a second preset time until the plaster dries and forms a brick-like mortar layer, the method further includes: After the plaster has dried and formed a layer of imitation red brick mortar, remove the joint strips.

[0013] In an embodiment of the present invention, the step of uniformly applying the slurry to be painted onto the primer layer and allowing it to stand for a second preset time further includes: Apply the plaster to be painted evenly onto the primer layer using a trowel or spray method.

[0015] Other features and advantages of the embodiments of this application will be described in detail in the following detailed description section. Attached Figure Description

[0016] The accompanying drawings are provided to further illustrate the embodiments of this application and form part of the specification. They are used together with the following detailed description to explain the embodiments of this application, but do not constitute a limitation on the embodiments of this application. For those skilled in the art, other drawings can be obtained based on the structures shown in these drawings without any inventive effort. In the drawings: Figure 1 This is a flowchart of the imitation red brick mortar laying process according to this application. Detailed Implementation

[0017] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0018] The following description, with reference to the accompanying drawings, describes the imitation red brick mortar laying process according to this application.

[0019] like Figure 1 As shown, in this embodiment, a process for laying imitation red brick mortar is proposed. The steps of the imitation red brick mortar laying process include: S10: Determine the mortar formula through experiments; S20: Mix the determined mortar formula with water according to the preset ratio to form a plastering slurry, wherein the preset ratio ranges from 18% to 20%; S30: Apply primer to the preset area of ​​the wall and let it stand for the first preset time until the primer dries and forms a primer layer; S40: Apply the plaster to be painted evenly onto the primer layer and let it stand for the second preset time until the plaster dries and forms a brick-like mortar layer. S50: Apply a topcoat agent to the surface of the imitation red brick mortar layer by roller.

[0020] The imitation red brick mortar laying process in this application includes the following steps: First, the mortar formula needs to be determined through experiments. Then, after determining the mortar formula, it is mixed evenly with water according to a preset ratio to form the plastering slurry. The preset ratio of mortar formula to water is 18%~20%. Next, a primer is rolled onto a preset area on the wall and allowed to stand for a first preset time until the primer dries and forms a base coat, which improves paint adhesion and facilitates subsequent application of the plastering slurry on top of the primer. The plastering slurry is then evenly applied onto the primer layer and allowed to stand for a second preset time until it dries and forms a faux red brick mortar layer, at which point the wall has a red brick appearance. Finally, a topcoat is rolled onto the surface of the faux red brick mortar layer. This provides stain resistance, scratch resistance, and corrosion resistance, effectively extending the lifespan of the red brick mortar layer. After completing the above steps, the faux red brick mortar laying process is finished. The mortar formula prepared in this application has good weather resistance and durability. Using the determined mortar formula to plaster the wall can solve the problems of insufficient weather resistance and durability of the existing imitation red brick mortar.

[0021] In addition, in this embodiment, both the primer layer and the topcoat are 1mm thick and both use acrylic emulsion to prevent alkali from seeping out of the substrate, thus providing stain protection. Preferably, the imitation red brick mortar layer is 3-5mm thick, which provides better protection and can effectively protect the wall.

[0022] In this embodiment, the step of determining the mortar formula through experiments includes: White cement, heavy calcium carbonate powder, quartz sand, and additives were selected as the mortar formula, and the proportions of each component in the mortar were adjusted. Performance tests were conducted on each group of mortars with different component ratios to ensure that the initial crack resistance, strength properties, and workability of the mortars all met the preset requirements. The mortar formula that meets the performance test requirements will be used as the mortar for imitation red brick paving.

[0023] Specifically, the steps for determining the mortar formula are as follows: First, it is determined that the mortar in this application uses white cement, heavy calcium carbonate powder, quartz sand and additives as the mortar formula, and it is necessary to ensure that the mortar has the workability to be rubbed after being applied to the wall.

[0024] Next, the initial crack resistance of the mortar needs to be adjusted. This is done by adjusting the sand gradation to ensure the mortar is fully compacted. The sand needs to be continuously graded (i.e., using sand from coarse to fine) to ensure that the initial wind crack resistance of the mortar meets the preset requirements. After a series of sand gradation adjustments in the laboratory, it was finally determined that the quartz sand used was Nanlian Huanzi sand (0mm-1.18mm), with an admixture content of 55%~72%, to ensure good crack resistance of the mortar.

[0025] Subsequently, to ensure the mortar's strength met requirements, extensive adjustments were made to the cement and adhesive powder dosages in the laboratory. It was determined that the white cement used in this application is a special 42.5 white cement, with an admixture content of 20%–25%. The heavy calcium carbonate powder used in this application is Leiyang Baihui 300-mesh heavy calcium carbonate, with an admixture content of 8%–15%. This ensures the mortar possesses high 28-day flexural strength, 28-day compressive strength, and original tensile bond strength, meeting the preset requirements.

[0026] Furthermore, to ensure the mortar working time meets the requirement of more than 30 minutes, the dosage of cellulose ether was extensively adjusted in the laboratory. Experiments revealed that the cellulose ether dosage needs to be between 1.2‰ and 2.8‰ to retain moisture and extend the working time. The starch ether dosage needs to be between 0.25‰ and 0.45‰ to meet the preset requirements and improve the mortar's anti-sagging properties.

[0027] Ultimately, it was confirmed that in this embodiment, the mortar includes white cement, heavy calcium carbonate powder, quartz sand, and additives. The proportion of white cement ranges from 20% to 25%, the proportion of heavy calcium carbonate powder ranges from 8% to 15%, the proportion of quartz sand ranges from 55% to 72%, and the remainder is the proportion of additives.

[0028] The results of performance testing on the mortar formulation are as follows:

[0029] As shown in the table above, the mortar with the above-mentioned proportions can be applied smoothly for 60 minutes without any obstacles. During initial drying, there are no surface cracks, and the flexural, compressive, and tensile bond strengths all exceed the test standards. Furthermore, there is no visible efflorescence or powdering. The mortar formulation that meets the performance test requirements exhibits good weather resistance and durability.

[0030] Furthermore, in this embodiment, the additive consists of an application modifier, a colorant, and a lubricant. The application modifier is present in a proportion of 1.5‰ to 3.0‰ in the mortar, and the colorant is present in a proportion of 31‰ to 34‰ to adjust the color of the mortar. The lubricant is present in a proportion of 1.5‰ to 3.5‰ to ensure the mortar is not too dry and is easy to apply to the wall. Preferably, the application modifier is present in a proportion of 2.35‰, the colorant in a proportion of 32‰, and the lubricant in a proportion of 2.5‰, at which point the additive exhibits good overall performance.

[0031] In this embodiment, the coating modifier is composed of cellulose ether and starch ether, wherein the proportion of cellulose ether in the mortar ranges from 1.2‰ to 2.8‰, and the proportion of starch ether in the mortar ranges from 0.25‰ to 0.45‰. Preferably, the proportion of cellulose ether in the mortar is 2‰, and the proportion of starch ether in the mortar is 0.35‰. At this ratio, the coating modifier has good anti-sagging properties, a long workable time, and good overall performance. The cellulose ether used in this application is Tianpu HK4M cellulose ether, ensuring that the mortar has a long workable time for construction workers to apply the mortar to the wall surface.

[0032] In this embodiment, the colorant consists of iron oxide red, iron oxide black, and iron oxide yellow, wherein the proportion of iron oxide red in the mortar is 17.5‰~18.5‰, the proportion of iron oxide black in the mortar is 4.5‰~5.5‰, and the proportion of iron oxide yellow in the mortar is 7.5‰~8.5‰. Preferably, the proportion of iron oxide red in the mortar is 18‰, the proportion of iron oxide black in the mortar is 5‰, and the proportion of iron oxide yellow in the mortar is 8‰. At this point, the color of the mortar is closer to the color of red brick, and the appearance effect after being painted on the wall is realistic.

[0033] In this embodiment, the particle size range of the quartz sand is 0mm-1.18mm. It has a large specific surface area and good filling properties, and the mortar with the above particle size has a delicate coating effect.

[0034] In this embodiment, after the step of applying primer by roller to a predetermined area of ​​the wall and allowing it to stand for a first predetermined time until the primer dries and forms a primer layer, the method further includes: Apply multiple joint strips at equal intervals to the primer layer.

[0035] Furthermore, the joint strip in this application includes a first joint strip and a second joint strip, and the step of attaching multiple joint strips at equal intervals on the primer layer can be further described by the following steps: First, multiple first joint strips are evenly spaced along a first direction on the primer layer. The first joint strips extend along a second direction. Then, multiple second joint strips are evenly spaced along the second direction between any two adjacent first joint strips. The second joint strips extend along the first direction. The first direction is perpendicular to the second direction to ensure that the attached first and second joint strips can effectively form a grid structure, which can imitate the function of brick joints.

[0036] The distance between the multiple first seam strips can be adjusted according to actual needs, and similarly, the distance between the multiple second seam strips can also be adjusted according to actual needs. The adhesion between the first and second seam strips is good, stable, and not easy to fall off.

[0037] In this embodiment, after the step of uniformly applying the plaster to be painted onto the primer layer and allowing it to stand for a second preset time until the plaster dries and forms a brick-like mortar layer, the method further includes: After waiting for the plaster to dry and form a layer of imitation red brick mortar, several joint strips are removed to ensure that the wall surface has an appearance similar to stacked red bricks, thus meeting the user's need for a red brick wall.

[0038] After the first and second joint strips are pasted at their positions using the above method, the entire wall is plastered with the plaster to be applied. The surfaces of the first and second joint strips will be covered with the plaster to be applied. After the first and second joint strips are subsequently removed, the wall surface will have an appearance like stacked bricks, achieving the effect of imitating a thick layer of red brick cladding.

[0039] In this embodiment, the step of uniformly applying the slurry to be painted onto the primer layer and allowing it to stand for a second preset time further includes: Apply the plaster to be painted evenly onto the primer layer using troweling or spraying methods to ensure good surface consistency of the imitation red brick mortar layer.

[0040] In addition, to ensure a good painting effect of the mortar, a primer can be applied to the pre-designed area of ​​the wall and left to stand for a first pre-designed time until the primer dries and forms a primer layer. After this step, the mortar and water are mixed evenly according to the pre-designed ratio to form the mortar to be painted, so as to avoid the mortar drying too early and affecting the painting effect.
