Floor paint construction elementary introduction common problems of the ground fissure

before floor paint construction, need to pay attention to many floor paint construction conditions, the epoxy floor level construction of the ground fissure is often met in the original concrete ground processing problem.

the most common is the dry shrinkage crack, generally because there is no cover or maintenance in time, after casting surface drying shrinkage, another common cause is the temperature shrinkage cracks, mainly because after pouring temperature difference is too large, such as the summer heat floor paint construction, or the winter low temperature floor paint construction is easy cause, this kind of irregular reticular crack generally shallow crack of concrete performance impact is not big, if the crack deep would reduce the durability of concrete. Other reason is that before the construction of the ground floor paint raw materials quality, stability, sand silt content, such as cement admixture don't adapt to, and so on. But if in the construction of epoxy floor paint, improper handling the floor base crack, can make the cracks expanded from the inside out to floor lacquer coating surface, affecting the surface of the floor paint effect or floor lacquer film shell formation, blister and other issues are likely to affect the service life of the epoxy floor.

by epoxy floor paint below small make up just before floor paint construction floor crack treatment methods to do a simple introduction of the base:

a lot of, the causes of cracks on the floor paint construction base level change of temperature cold heat, water shortage, low concrete strength and concrete curing period layer below the base surface is not flat, concrete slab stress non-uniform, can make floor surface cracks. When floor paint construction, if spotted the tear in the base level, application of cutting machine along the crack edge cutting, forming on the small of the v-shaped grooves. Then put inside the groove, sandstone, lime soil or other material was removed, mixed solvent epoxy primer quartz sand, in the end, just add a small amount of solvent free epoxy primer and stir well after quartz sand in the semi-arid state can, and then to fill concrete base surface grooves. Then, the cement base surface have the requirement of the floor paint construction.

only strict control of a good floor lacquer before construction conditions, to ensure the quality, make beautiful and durable floor paint engineering.
