Staining is fairly simple.
1. Find color of stain you like.
2. Make sure the wood surface is smooth and clean. I usually use 220 grit for surface prep before staining. Make sure all dust is off the wood before staining.
3. Use a clean rag or foam brush to apply stain. Apply the stain in the direction of the grain of the wood. Be somewhat liberal when applying the stain to make sure it penetrates the wood. Don't worry if it is a little streaky.
4. Once you get the surface covered with the initial coating take a clean rag and wipe off all the excess stain, again in the direction of the grain. This will remove the streaks and give you an idea of the color of the wood with the stain. If you want it darker let the stain set on the wood longer before wiping it off. Or apply another coat and let it sit longer before wiping off.
5. Let the stain dry for 24hrs. before applying clear coat.
