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

1, the requirement for concrete ground:

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

2 ground roughness general requirements within 2 m head is not more than 2 mm; Such as the gap is bigger, floor coating need to reduce the gap between increasing;

(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: vacuum 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.

(4) process: the whole grinding surface grinding machine again & ndash; After dust & ndash; To repair the large hole, sag and crack. For old paint surface, the same lacquer layer adhesion not firm, with the surface milling planer integral removing the old paint layer ( Old paint layer is below the thickness of 1 mm can use diamond cutting knife handle) , due to the high processing cost, if the customer does not require integral removing the old paint, loose only to remove old coating, removal of surface oil and impurities.
