PAINTING METHOD USING LOW DUST AND LOW NOISE

摘要

Provided is a method of painting a stone and a concrete structure using low dust chipping and fast curing mortar. The method includes a wetting and drying process (S10) of spraying hot water on a paint required surface of a stone and a concrete structure at a high pressure and naturally drying the wet surface; a surface processing process (S20) for spraying blasting slurry (S) at a high pressure by using a chipping machine (100) to chip the surface; a repairing process (S30) for spraying mortar including a binding material, fine aggregate and water on the dried surface at a high pressure; a curing process (S40) of curing the stone and the concrete structure processed by the repairing process (S30) for 2-4 hours; and a painting process (S50) for coating a paint on the surface processed in the curing process (S40).
