Delamination of Finish Over Stain

 

 

CAUSE

REMEDY
A Clear finish is peeling or shows poor adhesion and when removed, finish shows stain adhering to the back of the chip.

This usually occurs when the finisher is trying to obtain a very deep stain color such as a mahogany or a white white.

The application of too heavy of a coat of stain without wiping can leave a loose surface film of pigment. When the clear coat is applied over the pigment, it only adheres to the pigment and does not have good adhesion to the wood, therefore, leading to peeling.

Dark stain color should be obtained by using toners as a first coat before stain application. All heavy application of stains should be wiped before finish is applied. In addition, stain should be allowed to dry the time recommended by the manufacturer.
