Water - based wood paint common problems: gloss wood paint uneven luster Phenomenon There is light coating on the wood surface, coating film gloss, some areas of low gloss Cause The wood fiber and pith ray in cork are loose with the growth of growth rings, the base material infiltrates excessively, the coating film increases the pigment volume concentration due to the decrease of the base material, and the luster decreases. Other parts due to dense, less infiltration of the base material, pigment volume concentration unchanged, luster unchanged. If it is a varnish coating,loose parts due to the infiltration of base resin, coating thickness decreased, luster decreased. The thickness of the coating film is not uniform,not uniform luster. Perfection The substrate is sealed with high degree of polymerization and high molecular weight. The base material of coating is polymer or polymer emulsion with large relative molecular weight.The base material is larger than the wood hole of wood, so it is not easy to be absorbed.

Common problem of lacquer of waterborne woodwork: varnish besmear film is not level off, burnish is not even Phenomenon : Wood is filled with putty hole processing, after sealing the bottom, coating brush varnish, coating film flatness is low, luster is not uniform. Cause : Hole putty poor quality, loose, solvent absorption. The wood fiber and pith ray on the wood surface are relatively loose. The large pores on the wood are filled with the putty filler, but the putty itself brings a large number of micro pores. Because be bored with child filler content is high, filler itself also has bibulous amount. When be bored with child fine air void rate is high, coating absorbs water quantity to be too big, bring about coating dry fast, not level off, burnish is uneven. If the use of closed primer closed poor performance, not completely closed the wood surface, there is still part of the varnish is absorbed by the wood surface, resulting in uneven varnish coating and gloss. Improvement: Choose the putty with high compactness, add the sealing primer on the putty surface, select the sealing bottom with good sealing performance, and increase the number of coating paths appropriately.

Phenomenon: Wood coating water - based varnish after the grain fuzzy, grain color and luster differ, failed to retain the original style of wood. cause 1.Transparent putty transparency is poor or scraping too thick, reduce the clarity of wood grain. 2.Water-based paint storage time is too long, pigment precipitation, on the shallow under the deep operation without mixing evenly, coating film thickness is uneven. Improvement: 1.Choose suitable transparent putty, and pay attention to the construction thickness and uniformity; 2.Fully stir the water-based paint before use, uniform.

Phenomenon : Part of the water-based paint film from the primer uplift, which contains gas or liquid, showed uneven distribution. Cause 1.When the water-based paint is applied, the dry water-based paint film is exposed to rain. 2.Apply a water-based paint primer to the wet substrate; 3.Water based paint film is affected by acid - base and heat. Amelioration 1.Considering the gas phase conditions, the water-based paint film is completely dried and then re-constructed. 2.Substrate drying and surface treatment should be strictly implemented 3.Choose to accord with the conditions of use of good chemical resistance and good heat resistance of water paint varieties.
