4. Prevent Future Peeling or Flaking: Staining over an old, failing finish can lead to premature peeling or flaking of the new stain. Stripping eliminates this risk by ensuring a strong bond between the wood and the fresh stain.
Yes, this is the basis of refinishing furniture. Any time a piece is refinished the old finish and stain must be removed. The technical aspects of the process are probably of less concern to you than the practical ones so here is what you do. Chemical removal of the old stain is much easier and faster than sanding.
Yes, you can put a stain over an existing stain on a deck, but there are a few important considerations to keep in mind: Compatibility: Ensure that the new stain is compatible with the old one. If the existing stain is oil-based, it's best to use an oil-based stain on top.
Yes, you can stain wood that has already been stained. Sand the surface lightly to remove the top layer of the old stain, then apply the new stain. Proper preparation ensures a good finish. For more tips, see my Quora Profile.

You don't have to worry about sanding off the existing stain like you would if you were fully refinishing it with a traditional wood stain. Just lightly scuff the surface to give it some “tooth” so the gel stain will have the best adhesion.
If you plan on restaining or repainting you wood deck, you need to remove the old finish for the best, more durable bond. However, there ARE some products that are designed to be applied directly over your existing coat.
Remove any dust, grime or oils that could hinder stain penetration. Use warm, soapy water for general cleaning and consider a wood cleaner for heavily soiled surfaces. Always remember to let the wood dry thoroughly after cleaning.
Should I Pressure Wash My Deck Before Staining? Yes, pressure washing your deck before applying a new stain is a good idea. This will provide a much cleaner surface to work with, which should prolong the life of the stain.
Two Coats Recommended: Most manufacturers suggest applying two coats for optimal protection and appearance. Drying Time Matters: Wait at least 4 hours between coats and 24 hours before using the deck. Avoid Over-Application: Too much stain can lead to poor adhesion, peeling, and uneven color.
Generally speaking, it's a good idea to completely remove all traces of the previous coat of deck stain before applying a new one. The reasons for this may be fairly obvious — a previous coat of stain might be peeling away from the surface in several areas.
Natural Oils:
“These stains last longer and are more durable than unsealed water-based stains because there is no film on the wood to chip or fail,” according to the Green Home Guide, Tung oil is the optimal penetrating oil because it can penetrate, harden and still remain somewhat flexible.
You can still choose to refinish without sanding, but the new stain may accentuate existing scratches in the wood rather than cover them. Water damage or pet stains that penetrate the finish into the actual floorboards may also require a full on sanding of the floor.
Removing old stain isn't always necessary, but it depends on the condition and type of the previous stain. Water-Based vs. Oil-Based: Water-based stains sit on the surface and may need to be removed if peeling. Oil-based stains penetrate the wood and can be reapplied without full removal.
In some cases, your deck's previous coat of stain will begin to fade and peel from the surface, in which case it's best to remove it before applying a new coat. Other times, however, the old stain will stay put even if it's been there for several years.
Always prepare the wood with a light sanding.
Apply Minwax® Pre-Stain Wood Conditioner to ensure an even stain color (see Wood Preparation for other tips).
Sanding is an important step in refinishing a wood deck. The effects of weather and sunlight, as well as the deep cleaning that was just completed, will raise the grain of the wood. If the deck is to be stained, it's best to sand the wood smooth.
Before you apply stain, make sure the surface is clean (no dust, dirt, wood fibers or grease), dry and free from mildew. When a surface is not clean, stains and other finishes have trouble sticking and may end up peeling. Confirm no rain for 24-48 hours. Thoroughly sweep the deck to remove all leaves and other debris.
Restore-A-Deck Wood Stain Stripper: The Restore-A-Deck powder is consistently considered one of the best deck stain removers and easily removes old stain or varnish, along with dirt, mildew, mold, and mill glazes.
If you're going from a light stain to a dark stain, there's no need to strip away the existing stain first. However, keep in mind that the existing stain may alter the color of the finished product. Sand the surface of your project lightly with fine-grit sandpaper.
If you spray the dye and leave it without wiping, you won't get good grain definition. To improve the grain definition, apply an oil stain after the dye has dried — or over the sealer coat — and wipe off the excess.
You'll need to create a cleaning paste by mixing equal parts white vinegar and baking soda. Apply the paste onto the affected area and let it sit for about 30 minutes. Then, use a soft-bristled brush to scrub the spot. Use enough pressure but not too much that you'd damage the wood.
