Should You Wash Wood After Sanding

If the wood gets wet after its been sanded but not before youve had the chance to stain or paint it youll be back to square one youll need to wash and sand it all over again.
Should you wash wood after sanding. If your pressure treated wood has previously been sanded you may have to deal with how it looks until you decide to change the wood or cover it with a thicker or opaque stain which I dont recommend unless you want to deal with a peeling. If you seek a perfect finish make sure the tack cloth glides smoothly over the wood as you wipe. After stripping paint from wood you are left with leftover stripper residue that needs to be cleaned up before you can move onto any staining or painting.
After a deep power washing the wood fibers of the various components of the deck often raise as they expand with water. Instead use a tack cloth a sticky piece of cheesecloth made especially for this purpose. There are approved methods you can use to clean the dust before applying a polyurethane sealant or staining the surface.
You will need a hand brush to clean the dust. There are a few different ways you can remove this residue but through trial and error the most effective way for me has been through the use of mineral spirits and steel wool. If youve got brand new or gray untreated pressure wood you can choose to wash the deck with a cleaner rather than taking the risk with sanding.
Then blot it dry with. If you plan on staining using mineral spirits is even more important after sanding. Tack the floor with a DRY lint-free rag or towel.
What you would worry about is raised grain surface wood fibres swelling due to soaking up water. Yes removing the dust after sanding takes some effort. Dry rags or brushes arent the most effective tools for removing dust.
Once dry these wood fibers can often remain raised and may cause splinters. To answer your direct question no you dont need to clean the deck if all the wood is sanded down to raw wood. Even at 1500 PSI this pressure is still high and can damage softwood and go as.
