Sand in water construction practice and steps

Sand in water construction step 1. foundation treatment.

After the mortar is scraped, it needs to be maintained for more than 15 days, waiting for it to dry completely. Before scraping putty, there must be no moss, grease and other pollutants on the cement surface and the material being coated. If there is, it must be removed thoroughly, otherwise it will affect the adhesion of the putty.

Sand in water construction step 2. batch scraping putty.

This time it is recommended to use special gray crack-resistant putty for exterior walls, and putty after drying should be sandpapered to sand off the sharp corners and knife marks, sanding can also make the primer better adhesion in the putty, to prevent the emergence of hollow drums, skinning and other undesirable conditions. In addition, it is recommended to scrape the putty twice in batches.

Sand in the water construction step 3. rolling primer.

Next it's time to roll alkali resistant closed primer. Alkali-resistant sealing primer has the role of alkali-resistant and anti-salt precipitation, strengthening the substrate, enhancing adhesion, covering the putty color, and forming the color of the separation joints. That is to say, it can avoid the problem of alkali or frosting on the surface of sand in water caused by alkaline substances seeping out from the wall.

Sand in the water construction step 4. paste beautiful paper.

After the primer is completely dry, stretch the lines according to the size required by the designer, and then paste the patterned paper according to the position of the stretched lines, and gently press the patterned paper to avoid peeling off.

Sand in water construction step 5. roller coating and medium coating.

This step requires uniformity of roll coating and color consistency, so most construction masters are roll coating twice to meet the construction requirements.

Sand in the water construction step 6. spray color points.

Generally spray two times color point. After the first surface is dry, spray the second time. The texture and thickness of the spray is consistent with the color of the sample effect.

Sand in water construction step 7. tear off the paper.

After sandblasting in water, you should tear off the textured paper immediately, so as to avoid the situation that the textured paper can not be torn off after it is completely dry or tearing off the textured paper will damage the integrity of the paint surface.

Sand in water construction step 8. polishing paint.

After the paint is completely dry, it is recommended to polish it again. This step removes sharp paint corners and adds beauty.

Sand in the water construction step 9. roller coating top coat.

When rolling, make sure to be even.
