Home renovation, hydropower transformation is the first step, followed by waterproofing. Regarding waterproofing, there are three kinds of waterproof materials on the market. Each of the three materials has its own characteristics. In the field of household waterproofing, who is the most suitable waterproof material, and look at the following analysis.

As for the three waterproof materials we are familiar with, the new polymer cement-based waterproof coating (universal waterproof paste, flexible waterproof paste), 911 polyurethane and waterproof membrane.

Waterproof coil is not easy to splicing, it is mainly suitable for building roofing engineering, and it is not suitable for small-area waterproof construction of household; 911 polyurethane waterproof coating is difficult for families because of its volatile toxic gas, dry construction surface, and non-sticking of surface layer and ceramic tile. Accepted; and the new polymer cement-based waterproofing slurry is composed of organic polymer liquid material and inorganic powder compound, which combines the advantages of high elasticity of organic material and good durability of inorganic material, and forms high-strength and tough waterproof after coating. The coating film has the advantages of good waterproof performance, anti-aging, anti-cracking, etc. It is environmentally friendly and convenient to construct, and is an ideal choice for household waterproofing.

First, comparison of material properties and constituent materials

The new polymer cement-based waterproof material is an aqueous waterproof material, which is composed of an organic polymer liquid material and an inorganic powder material, and combines the advantages of high elasticity of the organic material and good durability of the inorganic material. Moreover, such coatings are non-reactive products, and the factory is strictly processed according to the formula, so the quality stability is high.

The 911 polyurethane is generally an oily waterproof material. A isocyanate group-containing prepolymer obtained by addition polymerization of an isocyanate or a polyether, and a single component prepared by a process such as a catalyst, an anhydrous auxiliary agent, a water-free filler, a solvent, and the like. Polyurethane waterproof coating. Urethane coatings are generally synthesized and synthesized by manufacturers. Their performance, process control, raw materials and many other aspects may cause quality differences. Especially for some small manufacturers, the conditions are simple and the quality of employees is low, so it is difficult to guarantee quality.

Most of the waterproofing membranes are made of petroleum extracts as invasive coatings, polyester fiber non-woven fabrics, jute cloth, glass fiber felts, etc., respectively, as the anti-adhesive insulation layer, selected materials, ingredients, and Melt, invasive, composite molding, curling and other processes are processed, and the process is numerous and duplicated, and the quality is difficult to guarantee.

Household waterproofing requires stable materials, environmental protection and is non-toxic and harmless. The new polymer cement based waterproof coating is the first choice for home waterproofing due to its excellent and stable properties.

Second, compare construction convenience and construction efficiency

The new polymer cement-based waterproof coating is simple to construct and greatly improves construction efficiency. Direct agitation can be applied in the correct way to form a strong waterproof layer.

Third, compare the resistance of materials against age

The new polymer cement-based waterproof coating combines the high elasticity of organic materials with the durability of inorganic materials. After coating, it forms a high-strength and tough waterproof coating film, which has the advantages of good waterproof performance, anti-aging, anti-cracking, etc. It is environmentally friendly, convenient to construct, and can maintain the product characteristics as usual in a harsh and humid environment;

Oily polyurethane is afraid of ultraviolet light and has poor weather resistance, so it can only be used for concealed engineering waterproofing;

The waterproof membrane is made of petroleum extract, which is prone to aging, cracking, peeling and delamination in the natural environment.

The cement-based waterproof coating is suitable for the waterproof environment of the family, especially the damp household waterproof construction environment such as bathroom and kitchen.

Fourth, compare the total cost

Cement-based waterproof materials are 1.5-2.0mm in accordance with national standards, with low dosage and low cost;

The oil-based polyurethane polyurethane waterproof material requires a thickness of 2.0-3.0mm per square meter of material at least 2.5-3.0kg, and the amount of material is large;

The waterproof coiled material is complicated to be spliced ​​in the home construction, and the labor cost is extremely high.

Cement-based waterproofing materials greatly reduce labor costs due to their high efficiency.

Fifth, consider the safety of construction

Cement-based waterproof coatings and waterproofing membranes can be constructed in any safe environment.

Oily oily polyurethanes require construction in a closed environment, which not only causes poisoning of construction workers, but also causes explosions.
