Dr. Rot,

I've read that CPES can be used over stains, but can it be used before staining? I have exterior Tudor wood on my home and I stain it from time to time. I'd like to treat the most vulnerable parts of the pattern, but I also want to be able to repeatedly stain the same areas periodically as needed.

CPES used before staining will inhibit the ability of the stain to penetrate/grip the wood. We cannot recommend it. Some of the heavier, pigmented stains will grip CPES-treated porous wood, but it's highly variable and often difficult to repeat tones and patterns.
