How to choose waterproof paint, choose soft or just choose

we choose waterproof paint, often ask: in the end waterproof paint is good rigidity or flexibility good?many consumers may have such doubts, of course, also heard some people say that the price of flexible waterproofing is a little higher than rigidity, so certainly flexible good. Is that really the case?
fact, rigid and flexible waterproof coatings, they are not good or bad, the so-called "soft" and "just" is only the product performance effect is different, can not be used as a criterion to judge the quality of materials.1, rigid waterproof
rigid waterproof relative to waterproof coils, waterproof coatings and other flexible waterproof materials, including waterproof mortar and waterproof concrete, rigid waterproof material refers to a certain proportion of cement mortar or concrete mixed with waterproof mortar or waterproof concrete material
China
.water resistance features:
(1) rigid waterproof material is not scalable. For example, common rigid waterproof materials have waterproof mortar and cement-based osmosis crystalline waterproof coatings.
(2) rigid waterproof roof and flexible waterproof roof comparison, its main advantages are low cost, good durability, less construction process, convenient maintenance.
: The main problem is that the uneven subsidion of the foundation causes the small deformation of roof components, temperature deformation is more sensitive, easy to produce cracks and leakage.2, flexible waterproof
flexible waterproof refers to in contrast to rigid waterproofing such as waterproof mortar and waterproof concrete, such as a waterproof material form, flexible waterproof through flexible waterproof material to block the water access, in order to achieve the purpose of building waterproofing or increase the ability to resist leakage.
waterproof layer under the external force, waterproof material itself has a certain degree of telescopic (e.g. rubber-like elasticity), can resist the elastic range of waterproof material grass cracking, showing a certain degree of flexibility.
characteristics: strong impermeability, high pull strength, low gentleness, large coefficient of friction, good stability and deformation adaptability to a wide temperature range, long service life and other good comprehensive technical performance., there is a certain difference between the construction of the two
rigid paint construction, the grass-roots conditions are not high, can be constructed on a damp substation. After the construction of the surface film hard, suitable for brick, so often used in the wall waterproof.
Flexible paint anti-deformation ability is strong, but the construction of the grass-roots requirements are more stringent, and because the film is soft, elastic, smooth, tile easy to slip, so flexible paint is often used for ground waterproofing, as well as pipe root, yin and yang angle of the enhanced use.
remember: flexible waterproof paint must be used carefully in the wall waterproof, and avoid large brick wall, to avoid the late tile tile fall off to pull off the waterproof layer phenomenon.
To say here, we should understand that the so-called waterproof paint is just soft, in fact, there is no good or bad, but the use of different parts and methods, each has its own strengths, we should pay attention to distinguish between Oh.
