Water-in-water and water-in-sand construction technology:
1. Environmental protection
1. Check the areas that need to be protected before construction.
2. Make building arrangements and cover window sills, door edges, trees and certain areas on the ground that may be contaminated with plastic film.
2. Base coat inspection and treatment
1. Carefully inspect the base wall surface for cracks and pits. Eradicate hollow, half-fallen and loose base surfaces.
2. The old wall surface should be cleaned to remove the old coating, floating dust, etc.
3. Use wire brushes, sandpaper, etc. to remove floating dust, grease and other powdered accessories.
4. If there is a lot of dust floating on the wall, use a high-pressure water gun to wash theexterior wall surface.
5. Fill cracks, dips and depressions with exterior wall putty and maintain for 5-7 days.
6. If the construction is based on a finished thermal insulation board, the surface of the board must be smooth and free from burrs, it must be polished with sandpaper.
3. Scrape the putty 1. Use flexible leveling putty to scrape the treated base surface 1-2 times. The putty should not be too thick each time to make the wall smooth.
2. Please apply a full batch of interface agent to ceramic tiles and mosaic walls first, then use a full batch of tile renovation sealant before leveling.
3. Polish the putty surface with water to remove floating dust and burrs on the surface.
4. After the construction of the putty is completed, it should be cured for 15-20 days (23±2℃)to ensure that the moisture content of the base coat is <10% and the PH value is <10.
5. Scrape the glossy flexible tape 2-3 times, with an interval of 12h (23±2℃) between each application, and dry for 24h (23±2℃) when finished.
6. Use fine water to buff the surface to make it smooth and smooth, providing a good base surface for building the paint.
4. Apply primer
1. Use a wool roller or spray gun to evenly apply the special sealing emulsion 1-2 times.
2. Once the primer is completely dry (6h/23±2℃), you can move on to the next process.
5. Spray colored imitation granite paint water in water in sand
1. Use a special spray gun to evenly spray the colored paint 1-2 times. (The diameter of the water in the water is generally about 3.0, and the diameter of the eau in sand is 3.5 to 4.0)
2. Each build interval is 12 hours (23±2℃).
3. After the colored paint is sprayed, dry it for 24 hours/23±2℃.
6. Spray the top coat
1. Use a spray gun to evenly apply the top coat 1-2 times.
2. The interval between each pass is 4-6h/23±2℃.
7. Coating maintenance
The coating will be completely filmed and cured for 7 days/23 ± 2°C. During this period, no human harm will occur.
8. Cleaning after building colored paint
1. One day after the process is completed, remove the protective film from the affected parts.
2. Cleaning, clean the affected parts and the floor.
9. Precautions for painting construction
1. Do not stir colored paints vigorously.
2. Do not mix other substances.
3. Do not add water tor dilute.
4. Try to use the paint immediately after opening the can.
Is there a difference between water-in-water and water-in-sand construction procedures?
Tianjin wall water sand is a common construction method, which has the advantages of sound insulation, heat insulation, fire prevention and resistance to humidity. Here is the construction method with water-coated sand on the walls of Tianjin:
1. Clean the wall first to make sure there is no debris or oil stains on the surface.
2. Then apply a layer of cement mortar to ensure that the wall surface is completely wet and even.
3. After applying the cement mortar, immediately pour the pre-measured cement mortar onto the wall.
4. Use professional tools to gradually compact and pound the cement mortar untiluntil all pores in the wall are filled.
5. Before the cement mortar is completely dry, use fine sandpaper or abrasive tools to polish the wall until the surface becomes smooth and flat, and remove the sand floating on the surface.
6. Finally, apply a coat of latex paint or varnish to protect and beautify the wall.
In short, water-coated sand wall construction in Tianjin requires high professional skills and experience. During the construction process, the corresponding specifications and safe operation requirements must be strictly adhered to to ensure construction quality and personnel safety. .
What should we pay attention to when spraying water-filled sand in hot weather?
There is not much difference in the construction process between the two.
1. Protect the environment arounde the construction zone.
Inspection and treatment of the base layer
1. Carefully inspect the base wall surface for cracks and pits. Eradicate hollow, half-fallen and loose base surfaces.
2. The old wall surface should be cleaned to remove the old coating, floating dust, etc.
3. Use wire brushes, sandpaper, etc. to remove floating dust, grease and other powdered accessories.
4. If there is a lot of dust floating on the wall, use a high-pressure water gun to wash the exterior wall surface.
5. Fill cracks, dips and depressions with exterior wall putty and maintain for 5-7 days.
6. If the construction is based on a finished thermal insulation board, the surface of the board must be smooth and free from burrs, it must be polished with sandpaper.
Pasticscrape
