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.

Abstract

A construction method of applying waterproof coatings before the cement finally condensates. This method includes the following steps: wetting with water on the base surface, then scrape a cement plasma layer or cement mortar layer, wait for the cement plasma layer or the layer of the cement plasma layer or orAfter the surface of the cement mortar layer is dry, scrape the waterproof coating to form a waterproof layer; or it can directly scrape the waterproof coating before the cement plasma layer or the cement mortar layer is finally condensed.The waterproof coating construction method described by the present invention has a reaction effect, solving problems such as the adhesion of the coating layer and the grassroots or protective layer, the slow drying speed of the water -based coating, and the high requirements of the base surface.The technical characteristics of the concrete basis or cement mortar base surface can be solved during large -scale construction. The problem that can also be constructed or construction can be constructed. The coatings can form a sealing adhesive layer to solve the problem of waterproof coating.

Description

technical field [0001] The invention relates to a construction method of a reactive adhesive waterproof coating, which belongs to the field of building waterproof construction. Background technique [0002] Ordinary water-based coatings require the base surface to be flat and dry during construction, and the base surface must be a solid base surface. The construction method generally adopts the direct brushing method. During the curing process, the coating itself relies on physical adsorption in the process of smearing and flowing, and combines with the capillary pores of the base surface to form a waterproof layer after the conjunctiva. Most of these construction methods are physical. Adhesion, the formed waterproof layer is easily affected by the environment, the adhesion cannot be guaranteed, and the image of water channeling often appears. Therefore, it is necessary to solve the problems caused by the waterproof construction method. Contents of the invention [0003]...
