Waterproof membrane waterproofing agent features

February 08, 2017

At present, there are many kinds of waterproofing membranes and waterproofing agents that have sprung up in the market. According to the insiders, these waterproofing agents are basically filled with tap water. There is no waterproof effect, just relying on big hits. Advertisements flicker the high-priced tap water of ordinary people, and there are countless examples of leakage caused by waterproofing agents.

The common "mortar waterproofing agent" is a rigid inorganic material. It is not waterproof. It must be mixed with cement, sand and other materials. By adjusting the proportion of the mixture to change the pore characteristics and increase the compactness between the materials, it is more common to make the cement river sand more Coagulate well to form a piece to increase their density. This material is only used as one of the multi-channel waterproofing processes in the formal waterproof construction process.

Water repellents have the following disadvantages:

So, what are the benefits of waterproof coatings?

1. Waterproof coatings are divided into water-based coatings and oil-based coatings. They are commonly used in water-based and oil-based prices. The non-toxic, harmless and non-polluting products produced by regular manufacturers are environmentally friendly coatings.

2, waterproof coating is waterproof coating film, coating film has high tensile strength, water resistance, weather resistance.

3, waterproof coating can be applied on the base surface of wet and clear water, and the bond is firm.

4. The waterproof coating is cold construction, no special equipment is needed, the operation is convenient, and the construction period is short.

5, water repellent is generally used in cement mortar, can not form a dense and impervious waterproof membrane, water will slowly pass through the waterproof mortar layer leading to water leakage;

6. The waterproof mortar made of waterproofing agent does not have any flexibility after drying and can not resist the slight deformation of the base layer, which is easy to cause leakage.

7. The compactness of the waterproof layer cannot be guaranteed. The plasterer construction, the uneven thickness, the thick branches and large leaves, and even the appearance of the pore honeycomb, make the waterproof layer even the basic impermeability, which is equivalent to no waterproofing, leakage is inevitable.
