What are the common waterproof materials, the advantages and disadvantages of the big reveal

Waterproofing is one of the important projects in the renovation, waterproofing project is related to the future of the problem of occupancy, and the impact of the project is good or bad, in addition to the construction process is the material, what are the common waterproofing materials on the market now? How to target the selection? I believe that many owners will want to understand this knowledge, the next detailed introduction to the common waterproof materials and the advantages and disadvantages of the issue.

What are the common waterproof materials?

1, cement mortar

Product features: cement mortar is an acrylate emulsion and a variety of fillers composed of organic emulsions, and then with special cement and filler materials composed of inorganic powders, and then after a certain proportion of the two-component water-based waterproof mortar.

Advantages: cement mortar belongs to water-based coatings, non-toxic, harmless and non-polluting, is very high environmental protection coatings, the material can be constructed directly on the concrete surface and bonded firmly, easy to construct, not subject to the grass-roots level of moisture content limitations, drying fast, condensation time is short, generally 2 hours after the construction of the grass-roots level of the surface can be pasted.

Disadvantages: this type of material is a rigid waterproof coating, after the film will be less elastic, will affect the waterproofing effect with the building settlement and dislocation, is more suitable for use in the structural stability of the location.

2, polyurethane

Product features: polyurethane waterproof coating has a "liquid rubber" reputation, and is currently on the market one of the best overall performance of waterproof coatings.

Advantages: film tough, high tensile strength, good extensibility, corrosion resistance, resistance to structural expansion and deformation ability, and has a long service life.

Disadvantages: these materials are not conducive to the construction of wet substrates, in the construction of fire safety requirements are higher.

3, polymer polymer

Product features: polymer cement waterproof coating is made of synthetic polymer emulsion and a variety of additives optimized combination of liquid and powder composite two-component waterproof coating.

Advantages: these materials are environmentally friendly and non-toxic, strong bonding with the substrate, fast drying, but it is mostly two-component materials, need to be guided by the instructions for the proportion of liquid and powder.

Disadvantages: Some manufacturers will add too much talc in the polymer polymer materials, which will greatly reduce the performance of the material, so in the purchase of such materials must be recognized when the formal brand.

4, acrylic

Product features: acrylic paint is the most important feature is that it can be diluted with water, which is a water-soluble material, colorless and tasteless, so the environmental protection is better.

Advantages: acrylic coatings in the drying of the film is very tight, and after the film elasticity and ductility are very good, will not be with the grass-roots level of the settlement and dislocation of the situation of fracture, this material is the current home furnishing in the waterproofing materials, and the price is also relatively affordable.
