Construction technology of external wall elastic paint .

Construction steps.

Base leveling-batching putty-exterior wall alkali anti-alkali primer-pasting imitation brick tape-topcoat construction-repair, acceptance.

The quality requirements of the coating construction base layer.

1. The base layer should be firm, no cracks, no powder, no sand, no hollow drum, no peeling, no lime burst point, no old coating with poor adhesion.

The base layer should have a flat surface, vertical elevation, yin and yang angles, square, no edges or corners, the depth of the grids should be the same, horizontal and vertical. The allowable deviation should meet the corresponding implementation standards and requirements, and the surface should be flat, not just flat.

3. The base layer should be clean, and the surface should be free of dust, scum, oil stains, rust spots, mildew spots, alkaline and salt analysis products, and no moss and other sundries.

4. The base layer should be dry. When applying solvent-based paint, the moisture content of the base layer must not exceed 8%; when applying water-based paint, the moisture content of the base layer must not exceed 10%.

The PH value of the grassroots level cannot exceed 9.

The concrete is cured for 21-28 days, and the plastered grassroots is cured for more than 14-20 days.

7 Before installation, the grassroots should be checked and accepted, and the painting can be carried out after passing the test.

Foundation leveling treatment

Scrape the exterior wall exclusive putty twice, each time the thickness is 1-1.5mm,

2. After drying, sand it with 260# sandpaper.

Maintain one with water, and apply the primer after drying.

The exterior wall alkali-resistant primer construction.

1. Painting tools: paint roller and paint brush.

The exterior wall alkali-resistant primer can be mixed with water by 30%, and it is evenly painted and there is no leakage.

3. Apply top coat after drying.

Top coat construction technology.

Apply top coat twice.

1. Painting tools: paint roller and paint brush.

The topcoat shall be applied twice, the first time of water mixing shall not exceed 10%, the second time of water mixing shall not exceed 5%, and the time interval between the first and second application shall not be less than 2 hours.

3. Partially refurbished, ready for acceptance.
