The construction method of applying waterproof paint before the final setting of cement
A technology of waterproof coating and construction method, applied in the direction of covering/lining, construction, building structure, etc., can solve the problem of slow drying speed of water-based coatings, high requirements on the base surface, and weak bonding between the waterproof coating layer and the base surface or protective layer and other problems, to achieve the effect of easy grasp, uniform thickness and reliable bonding effect

Embodiment 1
[0025] First, wet the cured concrete base surface that meets the construction requirements with water, and then scrape and coat a layer of cement slurry layer with a thickness of 1 to 3mm. After the construction of the cement slurry layer, within 3 to 4 hours, scrape coating on its surface Waterproof coating, the thickness of the formed waterproof layer after drying is 1-3mm. After the waterproof layer is cured, a layer of cement slurry is scraped on the surface to form a protective layer with a thickness of 1-3mm. The waterproof coating uses the inventor's patent: CN200910114456.X, which is a composition made of asphalt mixed with functional additives, fillers, thickeners and water.
Embodiment 2
[0027] First, wet the cured concrete base surface that meets the construction requirements with water, and then scrape and coat a layer of cement mortar layer with a thickness of 1 to 3mm. Within 3 to 4 hours after the construction of the cement mortar layer, scrape and coat the waterproof coating on its surface , so that the thickness of the formed waterproof layer is 1-3mm after solid drying. After the waterproof layer is cured, scrape a layer of cement mortar on its surface to form a protective layer with a thickness of 1-3mm. After the protective layer is dry, scrape it on its surface. Putty or tile. The waterproof paint uses commercially available acrylic waterproof paint.
Embodiment 3
[0029] Wet the base surface of the brick wall with water, and then scrape and coat a layer of cement mortar layer with a thickness of 1 to 3 mm. Within 3 to 4 hours after the construction of the cement slurry layer, scrape and coat the waterproof paint on the surface to make the formed waterproof layer The thickness after hard drying is 1-3mm. After the waterproof layer is cured, directly paste self-adhesive waterproof membrane on its surface to form the second waterproof layer, and then scrape and coat a layer of cement concrete on the second waterproof layer to form A protective layer with a thickness of 1-3mm. After the protective layer is dry, scrape putty or paste tiles on its surface. The waterproof coating uses CN200910114456.X, which is a composition made of asphalt mixed with functional additives, fillers, thickeners and water.
