Water bag how to avoid construction after the hair flower colorful coating white

After the construction, water bag water engineering coating began to form, this may be caused by a water bag water quality or construction. In terms of material, we can choose a strong, reputable manufacturers, but how do we prevent this problem in the construction? The proposed solution: 1. Spray varnish as much as possible when spraying. Roller is very simple, but it's easy to produce uneven local thickness, it may still cause frosting. Suggest the medium pressure, half overlapping spraying, pay attention to the atomization effect, avoid the accumulation of varnish prolapse agglomerate. 2. Whether spraying or roller coating, water bag water spray varnish usually have slight thickness difference. Too much coating will aggravate the problem of frosting and therefore coating should not be too heavy. 3. The coating and the underlying need to completely dry. After the film formation and drying, paint will form the hard sealing film. Containing water or impurities are most likely to lead to the bottom of the hard film on the surface of the sag and frosting. Therefore, covering surface must be completely clean at the grass-roots level, the construction shall be carried out after the water in the water completely dry. When choose cover varnish, use as far as possible low gloss or dark gloss varnish. High pervious to light the bright-coloured color of varnish will make the building colors more vivid and persistent. After completion of water package of water spraying, coating or coating is needed in the roller coating a layer of varnish, in order to prevent the water bag water coating structure is damaged, to achieve the effect of coating the clean. Because, however, are unlikely to get the same in each region on the surface of the outer wall smoothness, smoothness and roughness, so paint varnish can't completely uniform structure, thus increasing the possibility of a coating frosting. Especially in hot summer now, paint layer will have a certain degree of softening in the sun. Suspended particles in the air is convergent and infiltrate the paint layer, this will lead to water bag gray and flowering after a long period of time.
