5 to 10 minutes
Wipe the stain off immediately if you’d like a lighter tone. But for a deeper tone, leave the stain on the wood for 5 to 10 minutes before wiping it off. Be sure to wipe off all the excess stain going in the direction of the grain of the wood.
What happens if you apply second coat of stain too soon?
