When we choose waterproof coatings, we often ask: In the end, is the waterproof coating rigid or flexible? Many consumers may have such doubts, the price of flexible waterproof is a little higher than rigidity, so it is definitely flexible. Is this really the case?
Waterproof coatings can be divided into rigid and flexible. After the use of rigid waterproof materials, its strength is larger, and the flexible waterproof materials have good film forming flexibility after construction.
Flexible waterproof coating has high tensile strength, large elongation, light weight and convenient construction. Today, Xiaobian will explain the characteristics of flexible waterproof coatings in building waterproofing.
1. Flexible waterproof
Flexible waterproof refers to a form of waterproof material relative to rigid waterproofing such as waterproof mortar and waterproof concrete, etc. Flexible waterproofing blocks the water passage through flexible waterproof materials to achieve the purpose of building waterproofing or increase the ability to resist leakage When the waterproof layer is subjected to external forces, the waterproof material itself has a certain stretch and extension (such as rubber-like elasticity), which can resist the cracking of the base layer within the elastic range of the waterproof material, showing a certain flexibility.
Features: strong impermeability, high tensile strength, good low flexibility, large friction coefficient, good stability, good deformation adaptability, strong adaptation to a wide temperature range, long service life and other good comprehensive technical performance.
Flexible waterproof coatings are roughly the following categories: polymer waterproof coatings, polyurethane waterproof coatings, acrylic waterproof coatings, water emulsion type asphalt waterproof coatings.
Second, the characteristics of flexible waterproof coatings
1. The waterproof film formed by the flexible waterproof coating has good elongation, water resistance and weather resistance, and the waterproof effect is good.
2, waterproof layer weight is light, can even be used for light roof waterproofing.
3, the construction is convenient, it can not only be in the horizontal plane, but also in the façade, yin and yang angle and a variety of complex shapes of the surface construction, the formation of a seamless, complete waterproof coating film.
4. The waterproof coating on the basic surface is not only the main material of the waterproof layer, but also a binder with better performance. It can be used for base cracks, construction joints, rainwater buckets and through the periphery of the pipeline, etc., pasting carcass reinforcement materials, convenient construction, waterproof and leak plugging can be used.
5, the use of flexible paint waterproof, maintenance is more convenient.
6, the use of no need to heat, not only reduce environmental pollution, but also easy to operate, improve the working conditions.
