Home floor QiChang analyses of different base material handling

traditional painting do not take the base material processing, sometimes without any processing of concrete coated with primer, or only slightly do processing, processing way is a spade a spade, scan, removal of dust.

1, the surface of concrete requirements:

(1) leveling &compaction concrete request, strength requirement is not lower than C20;

2 ground roughness general requirements within 2 m drop is not greater than 2 mm, such as the gap is bigger, more floor coating need to reduce the gap;

(3) if you need painting at the bottom of the ground, underground water level is higher, the concrete base shall make waterproof processing;

(4) new concrete dry at least more than three weeks, the moisture content is not higher than 8%;

5] can also be used in terrazzo, etc. The coating on the substrate.

2, base material processing method for new concrete base material, USES the following approach:

(1) processing purpose: to improve the overall surface roughness, remove dirt and floating layer, obtain uniformity of rough surface to facilitate the coating adhesion.

2 processing equipment: since the vacuuming surface grinding machine ( Japan's imports) , vacuum cleaners, etc.

(3) requirements: to achieve solid, no blister, nest hole on the ground, also requires a dry, clean, no dust, oil, cement, sand and other impurities.
