When painting a wood door, a light sanding of the entire door with 180 grit sandpaper is required. Sanding helps open the grain to enhance the finish penetration and remove dirt or handling marks from the door.
It is strongly recommended that an oil based primer be used when painting either a finger joint or a veneer pine door. This prevents the finger joints from bleeding through the paint and the veneer from lifting. In addition, when finishing solid pine doors for exterior use, a tanning blocking primer should be applied prior to painting to avoid resin bleeding through the finished door surface.
Consequences of not using oil based paints lead to the following; finger joints being exposed, warping, and veneer lifting and cracking. These are not covered under our warranty.
