1, polished. Polish the concrete cement foundation to smooth it.
2. Pickle the ground. Clean the concrete floor - clean the water and soak the ground - clean with 8% dilute hydrochloric acid - rinse with clean water (restore the original color of the cement floor) - dry, no white powder and floating material on the surface, and circle the product The water is marked.
2. Handle the shrink seam. Clean all the dust and other impurities in the shrinkage joint of the concrete floor and repair them one by one with QT material.
3. Primer (0.2 kg/m2) for roller coating. In the case of drying the cement floor, the primer is evenly coated or sprayed evenly on the ground to achieve a film-free state on the ground.
4, leveling and repairing. In the water accumulated in the pickling process, fill the material with QT, fill in the depression in the field, and reduce the water accumulation.
5. Construction of elastic layer (dosage 1.2kg/m2/mm). When the primer is basically cured (can be applied to the person), the elastic layer (1-2mm) is scraped with a tooth scraper. When the previous layer is not sticky, it can be polished and applied. Layer (to make the adhesion between each channel stronger), if the coating film is thin (less than 1mm), the tooth scraper is difficult to level, can be scraped with a squeegee, should avoid in the morning and the hot sun Construction (the actual site uses more gums, two thicker at a time).
After the first polish
6. Construction of the surface layer paint (0.2 kg/m2). The elastic layer is not sticky (can be applied to the person). After the elastic layer is polished, it is necessary to ensure no water immersion within 24 hours after the construction.
1. Minimize the construction time between each floor, depending on the construction weather and construction conditions on site. If the interval process needs to be increased in cleaning and grinding, the adhesion of the material can be ensured.
2. The surface must be cleaned before each process in the construction process.
3. After the construction of the site is completed, it must be maintained for 5 days before being put into use.
