Apply your stain to the wood using a shop rag, brush, or roller. Always use the proper safety protection and gloves when applying and wiping stain. Stir stain well before applying to wood. The basic idea is to apply a wet coat and wipe off any excess before it dries. The longer you let the stain sit, or the more coats of stain you give your wood, the deeper the stain will be when it dries. Sometimes it’s appropriate to wipe off your stain within seconds of applying it. For example, if you want a hint of a darker colour overtop of a light stain you can apply and remove immediately. Other times it is more appropriate to apply stain generously (you can even pour it right onto the wood) and let it sit for a few minutes before wiping it off (just make sure it doesn’t dry before wiping), for a deeper application of that stain.
