Tutorial on pasting imitation bricks on the exterior wall of the building: sandblasting, painting or tiling on the exterior wall There are various kinds of imitation bricks for the exterior wall of the building, with superior performance and good quality, and they are safe and environmentally friendly. In addition, consumers pay more attention to environmental protection, health and personality. Therefore, the imitation brick on the exterior wall of the building is very popular. Nowadays, there is a large quality gap in the imitation brick of building exterior wall in the market, and the advantages and disadvantages coexist. How should we choose? What is the course of building exterior wall pasting imitation brick? I hope this article can help you and avoid detours. 1、 Which is better: 1. It is an era of energy conservation and emission reduction to solve the potential safety hazard of peeling off, and all the products we have developed hope to meet the requirements of energy conservation and emission reduction. If we stick wall tiles on the external insulation of the external wall, it is more likely to cause the potential safety hazard of peeling off wall tiles, and Lambao LB302 color brick paint, as a lightweight material and high adhesion product, can completely solve the problem of this potential safety hazard. 2 The cost of wall waterproofing is saved. The external wall tiles are prone to hidden cracks, causing water seepage in the wall. What's worse, there is no way to start repairing the cracks. For this reason, many projects will first do wall waterproofing before sticking the external wall tiles, which will virtually increase the additional cost (about 8-10 yuan/square meter of additional cost). Lambao LB302 color brick paint can avoid this water seepage defect without additional cost increase. 3 The use of color brick paint has more affinity. Color brick paint belongs to brick imitation products. However, in application, it can change the feeling defect of hard and cold exterior wall bricks. The wall with color brick paint has more rich texture and visual affinity characteristics, and increases the "breathing" permeability of the wall. 4. Make the shape of the wall richer. Color brick paint has more options in terms of color and brick segmentation shape, Change the rigid situation of the tiled wall. 5. Make the butt joints of the internal and external corners of the wall tiles more neat. The window sill line and the wall corner. The external wall tiles are cut into 45 ° bevel angles with two bricks, which is generally not easy to be neat, and the external corners are also not easy to be straight. Color brick paint can completely connect the wall tiles of two faces, and the external corner treatment is more complete and straight. 6 The cost of external insulation is reduced. Traditional external wall bricks cannot be used in high-rise buildings. However, when external wall bricks are pasted on external insulation of foreign enterprises, there are more restrictions. It is necessary to use steel wire mesh and other processes to improve the safety of external insulation structure of external wall, thus increasing the cost of external wall bricks (about 15-20 yuan/square meter of additional cost). 7. The cost without adhesive is to paste external wall bricks on external insulation of external wall, It needs adhesive bonding, plus the pointing agent of ceramic tile, which will increase the additional cost of 15-20 yuan/square meter, And the renovation cost is high. 9. The glazed surface of the exterior wall tile is easy to peel off, and the exterior wall tile is easy to absorb water. When the temperature changes sharply, it is easy to crack; In low temperature areas, due to the volume expansion of water freezing inside the exterior wall tiles, the light surface is easy to peel off. 2. Whether the exterior wall should be sandblasted or painted or tiled. 1. The sandblasting process uses the impact of high-speed sand flow to clean and coarsen the surface of the substrate. The compressed air is used as the power to form a high-speed jet beam to spray materials (copper sand, quartz sand, emery, iron sand, Hainan sand) High speed spraying to the workpiece surface to be treated will change the appearance or shape of the outer surface of the workpiece surface. Due to the impact and cutting effect of abrasive on the workpiece surface, the surface of the workpiece will get a certain degree of cleanliness and different roughness, and the mechanical properties of the workpiece surface will be improved. Therefore, the fatigue resistance of the workpiece will be improved, and the adhesion between it and the coating will be increased, It prolongs the durability of the coating film and is also conducive to the leveling and decoration of the coating (It can be divided into air spray painting, airless spray painting, electrostatic spray painting and other various spray painting methods), Different brands of spray paint have different toxicity due to different content of components. Pay special attention to safety when using, and avoid inhalation and skin contact (3) In the game "Go Kart", painting is a prop to change the color of the go kart. 3. Tile wall tiles must be firmly pasted, with the hollowing rate within 3%. There should be no defects such as skew, missing edges, corners, cracks, etc. The wall tile surface should be flat, clean, color coordinated, and the pattern should be reasonably arranged, without discoloration, alkali, stains, and significant gloss damage. Brick joints should be filled tightly, straight The width is uniform, the color is consistent, the lap direction at the internal and external corners is correct. The use part of incomplete bricks is appropriate, the arrangement is straight, the size of reserved holes is correct, and the edges are neat. The check flatness error is less than 2 mm, the vertical error of elevation is less than 2 mm, the height deviation of joints is less than 0.5 mm, and the flatness is less than 2 mm. 3. Related concepts 1. The external wall is defined by the judgment method, and A~B is set as a wall, If the A-B wall line can cut the relevant enclosure structure, it is the internal wall, otherwise it is the external wall. From the perspective of architecture, the exterior wall is the component that encloses the building to form an indoor and outdoor boundary. Its functions include: bearing a certain load, sheltering from wind and rain, heat insulation, noise prevention, fire safety, etc. 2. Ceramic tile, also known as ceramic tile, is a kind of acid and alkali resistant ceramic or stone material formed by grinding, mixing, pressing, glazing and sintering of refractory metal oxides and semi metal oxides. Building or decorative materials are called ceramic tiles. Its raw materials are mostly mixed with clay, quartz sand, etc. Related recommendations 150500 imitation stone external wall tiles 2017 Popular external wall tile pictures 2017 Rural external wall tile renderings Rock chip manufacturers: the application of rock chip in imitation tile paint _ Rock chip manufacturers Background wall imitation stone ceramic tile Rural external wall imitation stone ceramic tile Mould texture paint Difference between imitation brick paint and ceramic tile Imitation blue brick external wall ceramic tile Rural house external wall ceramic tile pictures Rural house external wall ceramic tile pictures
