- It is crucial that you remove any mold, mildew and dirt from the surface of the wood.
- A good cleaner formulated specifically for wood and will remove mold & mildew. Cleaning the deck with a stiff bristle deck brush is a necessary step in any successful staining project. This will remove mildew stains and provide a sound surface to stain. You never want to use regular soap and water to prep a surface because soap will leave behind residue which will reduce penetration. When thinking about other household cleaners, note that they either won’t effectively clean the surface and/or could damage the wood.
- Follow the product guidelines for the cleaning solution carefully.
- If the surface still has loose wood fibers, splinters, or has a very rough feel to it, we recommend that it be sanded smooth with a 80-100 grit sand paper. This is strong enough to smooth the surface and still allow stain to penetrate. (TIP: Always sand in the same direction as the wood grain to avoid marking the surface with your sandpaper).
- There are numerous electric sanders on the market to assist you with this task. If there is a small section of decking that needs attention, a pole sander will helps with the task and is easier on the back than bending down.
- Mechanical grinding can damage or destroy a wood surface very easily and should be left to a professional.
A Note About Priming
When you plan to apply a solid color stain to a deck or if you have your siding has chronic problems like continued Tannin Bleed, we recommend the use of a primer first. A primer will increase the adhesion of the topcoat therefore extending the life of the stain. Oil-based primers help with moisture vapor transfer on siding. In many cases, moisture trapped behind an unprimed coating can lead to surface peeling.
