Product Overview

JS polymer cement-based waterproof coating is a new type of waterproof material. It is a two-component water-based building waterproof coating made of building polymer lotion and special cement as the main raw materials, and added with other additives. Therefore, it has a "rigid flexible" waterproof characteristic.

Product Features

1. Easy to construct, widely applicable, and has obvious advantages in the construction of complex parts.

2. After curing, a seamless and complete elastic waterproof layer is formed, which improves the waterproof and anti-seepage ability of construction projects, which cannot be achieved by roll products.

3. The coating has high strength and extensibility, and has strong adaptability to cracking or expansion of the base layer.

4. Easy to repair, only partial repair of the damaged area is needed to achieve the original waterproof effect.

5. This product has bright colors and can play a decorative and beautifying role. It does not have strict requirements for the moisture content of the base layer, and can be applied to damp surfaces.

Construction method

Base treatment

Clean and level the base surface, keeping it free of cracks and looseness; Make the yin-yang angle into a circular arc angle; Grind down sharp areas.

Ingredients for polymer cement-based waterproof coating

1. Proportion of polymer cement-based waterproof coating (weight ratio): Liquid material: 32.5R or above ordinary silicon cement=1:1;

2. Proportion of polymer cement-based waterproof coating (weight ratio): Liquid material: 32.5R or above ordinary silicon cement=1:1.5;

3. Proportion of polymer cement-based waterproof coating (weight ratio): Liquid material: 32.5R or above ordinary silicon cement=1: (2-2.5).

Node processing

Splash water to moisten the base surface. For corners, through wall pipes, floor drains, construction joints, etc., use Sichuan type polymer cement-based waterproof coating with fiberglass cloth for reinforcement treatment, with a thickness of about 1.0mm.

Waterproof layer coating

Take the material according to the prescribed ratio and stir thoroughly with a mixer for about 5 minutes until there are no lumps in the coating. If water needs to be added, it should be added to the liquid material first, and the powder should be slowly added while stirring with a mixer. The pigment dosage for colored layer coatings is less than 10% of the liquid material, and only the pigment needs to be added to the surface coating. When coating, it should be as uniform as possible, without local deposition, and it is required to roll and brush several times to ensure that there are no bubbles between the coating and the base layer, and the bond is tight. When using non-woven fabric for construction, the bottom and top coatings should be applied continuously. The non-woven fabric should be laid flat and brushed tightly without leaving any hollows. Brush the second layer directly after the first layer is non sticky (each layer is about 0.6mm, not too thick); Generally, waterproofing requires brushing two or more layers, and then sprinkling a thin layer of sand on top of the waterproof layer before it dries to enhance its adhesion with the protective layer. After brushing, brush the edges of the coating a few more times before finishing; Wait for the waterproof layer to completely dry and solidify.
