May be applied using sprayer, roller or brush onto the woods surface. "Goof Proof" application. is darkest when first applied. Do not apply over painted or newly stained surfaces. Sealed surfaces inhibit penetration.
Given its color, all I can say is: 'It's the sh**' !
A very fine stain, says my limited experience. I use it out of the can only, as particles separate out pretty quickly, and it needs frequent stirring. I've used it both to treat new wood and recoat a porch that was fading fast and, while it LOOKS way better as a new stain, I was surprised how well it stuck to the 1 x 6s on the weathered porch!
