The sequence of the construction process of rolling wall: Grassroots treatment → finding rules, making gray cakes → wipe the bottom layer, middle layer mortar → bomb line → wipe surface layer ash roll coating. The rolling grassroots treatment, finding the rules and making gray cakes, the bottom layer, and the middle mortar bullet line are the same as spraying. Different places are just the construction method of the surface layer. There are two operation methods: vertical rolling and horizontal rolling coating.
(1) Vertical roll. When rolling, master the dry and humidity of the bottom layer. When the water absorption is faster, the water should be properly wet and moist, and the amount of watering should not be flowing when applying. Two people need to cooperate when operating. One person applied the mortar in front, and the palaces were scraped tightly, and then used the presence to roll the roller and pull it. When operating, the Art Roller should not run too fast, the gestures are consistent, rolling up and down, left and right, and adjust the pattern at any time to make the pattern consistent. And when the final survival is required, the rolling direction must be pulled from top to bottom, so that the rolling pattern has a natural flowing water slope, so as not to contaminate the wall in the future. After rolling, start the division bar. If you are required to do the corner, the corner is usually carried out when the large surface is alive. In order to improve the durability of the rolling coating and slow down the pollution and discoloration, it is generally sprayed with the silicon water solution (water hate) after 24h after the rolling layer. When there is a light rain in the inside, the silicon sprayed on the surface will be flushed off. If it does not achieve the due effect, it must be sprayed again.
(2) Roll horizontally. The horizontal roll coating is basically the same as the vertical rolling coating operation. Because the floor is flat, the roller is short, and it is inconvenient to operate. Painting Roller can roll some jets and roll it in the middle position twice in a rolling.
Construction points for art coatings (1) The thickness of the surface layer is 2 to 3mm, so the bottom surface is required to be straight and calm to ensure the effect of the surface layer. (2) If you find that the mortar is too dry when rolling, you must not sprinkle the water on the roller surface. Add water to the gray barrel to mix the mortar and consider the consistency of the mortar. (3) It is found that the mortar should be mixed well before using it, otherwise the phenomenon of "flower face" will occur. (4) Daily segments should be done every day. Do not leave live , and they must not be repaired afterwards, otherwise there will be inconsistent patterns and colors. (5) The ingredients must be grasped by special person. Strictly follow the coordination ratio and control the amount of water. The mortar should be mixed well when used. Especially with color mortar, it should be strictly grasped by the combination ratio, grassroots humidity, sand particle size, moisture content, mortar consistency, and number of rolling times.
