I would like to apply it to some wood that has some narrow crevices that are somewhat deeper than 2 inches. It is not a flat surface.
I found these instructions:
Fully mixed PC-WOODY® has a light brown or tan appearance without any streaks of white or brown. Spread the mix on the mix board to a thickness of about 1/4 to 1/2 inch.
Can I apply 1/4 to 1/2 inch, let it cure and then apply additional coats as needed?
