Stone paint construction common problem solving methods?

Skin and skin? Reason: the main use inferior putty, putty maintenance time is too short, hardness, surface treatment is not clean, base material the high humidity. Suggested processing method: remove processing, brush again cotea metope fixed permeability primer, and then use cotea triad putty ( Waterproof, elastic, putty) Blow to batch, meet the coating requirements after besmear again in the process of coating, coating, etc. The color difference? Reason: the color difference between different batches; With big batch chromatism, paint construction time interval is too long. Recommended approach: the same metope to use the same material as far as possible, a spraying the same wall, shorten the construction interval. Hang? Reason: coating is too thick, construction distance is too small and too much traffic, etc. Methods: before each spray, spray, try, try to adjust according to the state of spraying, if there is no exception, spraying effect for large-scale construction again. Suggest debugging related equipment ( Output pressure, paint, etc. ) 。 ) Before spraying. Crack? Reason: too thick coating, spray coating at low temperature processing methods: suggest serious crack, and then evenly spray it again. 'Bian base? Reason: the wall moisture content is exorbitant, high basicity processing method: remove processing, brush again good wall fixed permeability primer, and then using putty (section plus 3 in 1 Waterproof, elastic, putty) Blow to batch, meet the coating requirements, and then used in construction, stone coating, etc. Flowers? Reason: in the process of spraying film thickness is not uniform, a man not spraying spraying method difference is too big. Recommended processing method: before spraying, it is recommended that the adjusted spraying equipment ( Output pressure, paint, etc. ) 。 ) One operator to normal, normal effect a wall spraying construction.
