Wood Deck Stain Strippers and Removers
It is important to remove old failing deck stains prior to applying a maintenance coat. Failure to do so can jeopardize the protection and performance of the new stain because it cannot penetrate the wood correctly.
To remove an old deck stain you will need to use a deck stain remover. Deck stain removers are more aggressive than deck cleaners. They will soften most water and oil based semi-transparent and semi-solid deck stains so they can be washed from the wood more easily. They are also effective at removing dirt, mold, mildew, and UV graying.
Most deck stain removers either come in a liquid ready to use formula or a concentrated powder that is mixed with water. When applied, a deck stain remover breaks down and emulsifies old stains so they can be washed off using a pressure washer or a stiff brush and garden hose.
Without the use of deck stain strippers, most deck owners will try using excessive water pressure which is mostly ineffective and can damage the wood leaving it permanently splintered or furred. Even older stains are tough to remove without the use of stain removers.
For more stubborn deck stains like solid colored stains or acrylic based stains, even an aggressive mix of deck stain remover may not remove all the old stain. Several applications may be necessary as well as longer dwell times.
After wood deck stain removers are used it is a good idea to apply a wood deck brightener. This is even necessary after using a simple wood cleaner. Because both cleaners and wood stain removers are caustic formulas they will raise the pH level of the wood and cause it to appear very dark in color. For the best performance of a new deck stain, you want the wood more acidic. Applying a wood deck brighter, also called a neutralizer, you will correct the pH level of the wood which will essentially brighten the wood and provide a more suitable surface for the new deck stain.
Applying a deck brightener is easy. Simply rinse the wood after stripping it with a deck stain remover and apply the brightener as directed. Allow it to remain on the surface for a few minutes then re-rinse and allow the wood to dry prior to applying your new deck stain.
Deck stain removers are very helpful in removing old failing stains from decks and other exterior wood surfaces. They will remove most deck stains to provide a clean surface so your new deck stain can penetrate better and give lasting beauty and protection.
