During deck or wood maintenance it is important to prep the wood correctly so the new stain you apply can perform as expected. Any old failing stain that may be left on the wood may end up causing the new stain to peel, flake, and fail prematurely. There is no need to hinder the performance of a new deck stain by leaving remnants of old stain on the wood surface. This is easily remedied by using a deck stain stripper during the cleaning and prepping process. Today there is a product that is user-friendly that homeowners can use to get professional like results when it comes to prepping a deck.
If an old failing stain is present the use of a stain stripper will help to emulsify the stain so it can be washed away using a pressure washer or stiff brush. The first and only powdered concentrated deck stain stripper, designed to be injected through a pressure washer is Restore-A-Deck Stripper. Reviews have indicated that this product can also be applied in higher concentrations if necessary by the means of a pump up sprayer.
