For the best results when cleaning and maintaining a wood deck, removing all the old deck stain is crucial. Deck stain is meant to penetrate into the wood to provide protection. When an old stain remains on the wood it prevents any new stain from penetrating. The newer stain will instead remain atop the old stain and will be prone to peeling and flaking.
To ensure the new deck stain dives into the wood and provides adequate weather protection, any existing deck stain must be removed. During the wood cleaning process, a deck stain remover should be used. When using a deck stain remover it is not necessary to use a deck cleaner. The deck stain remover will not only remove old stains but dirt, grime, mildew, and graying as well.
There are many types of deck stain removers on the market. Liquid and powdered forms are the most common. The liquid forms are usually ready to apply while the concentrated powder forms require mixing with water.
Deck stain removers can be applied to most any exterior wood surface or deck to aid in proper cleaning and prepping for stain. Stain removers are commonly applied using a garden type pump sprayer but may also be applied using a soft brush.
Deck stain removers are very aggressive and will emulsify most semi-transparent and semi-solid deck stains. For hard to remove stains several applications may be necessary. Deck stain removers may not remove all deck stains especially some solid stains or paints.
Deck stain remover is a great way to aid in proper cleaning and prepping wood for a new stain application. The lack of removing deck stains leads to excessive buildup, darkening, and peeling. Deck stains do not adhere well to other deck stains, so removing a failed deck stain prior to a new application is definitely the best option to ensure excellent results.
Always wear protective gear when handling any type of cleaner or stripper. Protect landscaping, windows, concrete and other non-targeted areas with plastic or tarps prior to cleaning. Follow the recommended directions per the product label for the best results. Use caution when cleaning wood with a pressure washing. Getting too close to the wood can cause permanent damage.
It is best to apply a wood brightener to the deck following cleaning or stripping. This will reverse the darkening effect on the wood and will ensure proper stain penetration.
