How To Do Waterproofing On The Floor

1. The first step of floor waterproofing is to clean up the grass-roots. After cleaning, it is necessary to deal with the Yinyang angle, expansion joint, construction joint and other key parts. Especially for those parts which are not easy to be brushed, such as drainage holes, it must be strengthened to apply 2-3 times of waterproof primer paint.

2. Material used for waterproofing of flooring should be prepared, and attention should be paid to distinguishing waterproofing rolls, waterproofing coatings, base coatings and coatings for adhering rolls. Brush the underlying coatings. In order to improve the cohesiveness between waterproof membrane and base, the bottom coatings can be applied repeatedly, and the coatings are uniform, completely covered, and fully infiltrated into the concrete base, so as to improve the cohesive strength and shear strength.

3. Waterproof coatings must be proportioned according to the instructions of product use and A:B=2:1. Each mixing amount should be matched with the actual dosage on site.

4. Waterproof coatings should be stirred evenly, stirring time is about 3-5 minutes, and stirring until the mixture of A and B components is even.

5. The waterproof coatings with uniform stirring will be painted according to the area to be painted on the spot, and the area of the base coatings will be larger than that of the sticky coils. Waterproof paint is not easy to exceed 30 minutes at the latest from the end of mixing to the end of painting.
