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.
