Poor Adhesion to Substrate
The paint film does not adhere to the substrate properly; it peels off here and there. This is due to Poor Adhesion to the Surface.
|Unclean surface||Clean the surface with volatile solvent|
|Lifting of Primer of Sealer from the Surface – An Incompatible Finish. The Solvent in the Finish coat lifts the primer from the surface.||Ensure to use recommended primer and finish coat together.
Though the film will dry and appear good, primary adhesion will be ruined.
|Sanding the wood to a Smoother consistency. The problem is rampant in hardwoods that have closer grains.||
• Use 120 grit sand paper. for wood that have closer grains.
• Use 120-180 Emery paper for softwoods and wood with open grains.
|Stain Comes off along with the sealer||Apply a thin coat and then, wipe the stains off.|
|Applying Stains that are too Heavy. Either they are not wiped off or they did not dry, after application.||Ensure that the stain is dry, prior to applying the sealer.|
