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 1-3cm. 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 1-3cm. After the protective layer is dry, scrape 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 1-3cm. 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

The invention relates to a construction method for paining waterproof paint before cement is finally set. The construction method includes the steps of (1) wetting the base with water at first, blade coating a pure cement layer or a cement screed layer, and coating waterproof paint with a blade after the surface of the pure cement layer or the cement screed layer is dried to form a waterproof layer; (2), or coating waterproof paint with a blade directly before the pure cement layer or the cement screed layer are finally set. The construction method for paining waterproof paint before cement is finally set has reaction, solves the problems that adhesion of coating layers and bases or protective layers is insecure, drying speed of water-based paint is slow and requirement on bases is high and the like, construction is simple to operate, technical features of waterproof materials can be fully utilized, the problems that screed-coat layers are not needed to perform construction on concrete bases or cement mortar bases are solved in large-scale construction, paint can form a sealed bonding layer to solve a problem of water leakage of waterproof paint.

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]...
