What are the waterproof coatings for home improvement?
1, flexible mortar:
The ratio of emulsion to mortar is 5:4, which is elastic. Even if the bottom layer is deformed and cracked, it will not affect the waterproof effect. It is mostly used for meeting water surfaces such as walls and floors, but not for back water surfaces such as top surfaces. If waterproof is not done well, it is easy to wrap it up and leak water.
2, hard mortar, also known as rigid mortar:
The ratio of emulsion to mortar is 1:4. After brushing, the coating does not need to be treated, and it is convenient to stick bricks directly. The cement block formed after curing will not leak water, and its back water surface has good waterproof effect, which is its great advantage. The disadvantage is that this kind of mortar has high hardness and simply cracks with the deformation and cracking of the bottom layer, so it is generally used for waterproofing of the back water surface.
3. Polyurethane:
For indoor and outdoor use, the brush finish is very thick, about 3 mm, and the elastic tension is above 300%, so it is very elastic, and the cracking of any base material will not make it crack, and the waterproof effect is good. Although the safety function is controlled in environmental protection requirements, this kind of waterproof coating has a strong smell, which is difficult for ordinary people to accept, and a few waterproof brands are unqualified in environmental protection function. Polyurethane is gelatinous and thick, so it is laborious and complicated to use a scraper in construction.
4. Acrylic resin:
Acrylic pure liquid, ready to use when opened. Water-based, water-soluble, it is easy to combine with cracks in the ground to form a solid waterproof layer, which is better than flexible mortar. Flexible mortar and acrylate are more suitable for long-term immersion because of their good waterproof effect. Acrylic acid was also widely used in environmental protection paints and coatings earlier. The characteristic of this material is that it can be diluted into a water-soluble material with water, and it is colorless and odorless (the paint can be mixed with colorants according to requirements), but it is indeed a very fine waterproof material after conjunctiva. Therefore, the current paint basically has no paint smell (it used to be mixed with gasoline or thinner). This material has appropriate elasticity and ductility behind the conjunctiva and will not break with the settlement and dislocation of the bottom layer.
