Waterbase Finishing Schedule

Standard process for finishing an instrument with waterbase lacquer



i-waterbase Updated 06/06

Special waterbase application tip

Waterbase finish doesn’t look wet and glossy as you’re spraying, unlike nitrocellulose lacquer. Be careful not to lay it on too thick, looking for that glossy wetness. Good lighting is very important. Spray light coats, carefully overlap your spray pattern by 1/3-1/2 for coverage with uniform thickness.


This newly-sprayed coat is wet, but looks dry and pebbly (like orange peel).


Moments later, it turns wet and glossy.


When finally dry, it turns satin-smooth.
