Introduction of construction technology of real stone paint

Real stone paint is similar to the decorative effect of natural stone, and is widely used to build the exterior wall of villa with pastoral style and the courtyard with natural pastoral style. Do you know the construction technology of real stone paint? Let's study together!

A, real stone paint construction preparation

1. Basic requirements: smooth and dry surface (curing period is longer than 10 day), free of floating dust, grease and asphalt, and PH value of wall foundation.

2. Tool preparation: putty knife, steel wire brush, putty scraper or scraper, putty tray, sandpaper, roller, air compressor for special spray gun for sand wall coating, film adhesive tape, shielding plate, covering paper, plastic protective glasses, masks, gloves, work clothes, portable electric mixer, filter screen, plastic bucket, even plate, steel tape measure, and powder wire package.

Second, the real stone paint construction technology

1. process flow: base treatment, primer, single item acceptance, finished product protection, polishing, intermediate paint and topcoat spraying.

2. Basic treatment: the plastered wall surface should be smooth and firm, and the missing edges and corners should be repaired in advance. The repair adopts brush cement slurry and 20% glue solution, and then 1: 3 cement mortar for local leveling, which meets the requirements of intermediate plastering. Painted walls should be dry,

The moisture content at the grass-roots level is 8%, and then the decorative surface is treated with putty scraping, and the finished decorative surface can not have cracks, holes, depressions and other defects; 3. Brush sealing primer: In order to improve the adhesion of real stone paint, the sealing primer should be brushed on the surface of basic data. The sealing primer can be rolled or sprayed with a spray gun. The coating must be uniform and brush leakage is not allowed.

4. Spray imitation stone paint: Before spraying, mix the real stone paint evenly, put it in a special spray gun, and then spray it. The spraying pressure should be controlled at 0.4-0.8Mpa, and the spraying sequence should be from top to bottom and from left to right, and spraying should not be missed. When spraying real stone paint, a thin layer should be sprayed quickly, and then slowly, steadily and evenly. The effect of spraying depends on the size of the nozzle and the distance between the nozzle and the wall. When the diameter of the nozzle is Ф 6-Ф 9, and the distance between the nozzle and the wall is properly adjusted, the ejected light spot is larger and the convexity and concavity are stronger. When the diameter of the nozzle is Ф 3-Ф 6 and the distance between the nozzle and the wall is appropriately reduced,

Small spray point and smooth finish. However, the distance between the nozzle and the wall should be controlled at about 0.4-0.8M, which should not be too large or too small; 5. Polishing: The real stone paint should be solidified after spraying. After 24 hours, when the real stone paint is completely dried, it should be properly polished and the decorative dust should be cleaned. Topcoat: After the topcoat is cleaned, the topcoat should be sprayed or sprayed. If spraying is used, the spraying pressure should be controlled at. It is required that the top coat be painted (sprayed) evenly and with the same thickness, and brush leakage is not allowed.

6. Spraying: spraying (brush coating or roller coating), evenly and thinly spraying with an airless spray gun, the construction temperature is not lower than 10℃, it takes 10 days for complete drying, and the spraying amount is 0.2-0.3Kg/m2.

The knowledge about the construction technology of real stone paint is introduced here for everyone, hoping to help you!
