When it comes to restoring an older wood deck, it’s extremely important to prep the wood correctly. Not doing so can lead to premature failure of the new deck stain. No matter the brand or cost of a deck stain, it will not last as long as it should if it isn’t applied to a perfectly cleaned and prepped surface.
One of the biggest mistakes DIY homeowners make in cleaning and preparing a wood deck for stain is not removing all remnants of old deck stain. Any failed deck stain that is left on the wood will block the new stain from penetrating the surface properly. The new deck stain will sit on top of the wood instead of diving into it. Deck stains do not adhere to each other well so this causes the newer deck stain to begin flaking and peeling off the deck normally in a year or less. Even if you can’t see any old deck stain but you know there was some on the wood at one time, it’s vitally important to remove it. Splash some water on the wood and see if it absorbs into the wood or if it beads up and sits on top. Beading up would indicate there is some type of old failed stain on the wood that needs to be removed.
To remove old deck stain from the wood you have to use a deck stripper. A quality deck stripper will break up and soften any old stain allowing it to be washed away. Most deck strippers will not remove solid stain or paints if this is the case you may have to sand the old stain to get back down to bare wood again.
Once the deck has been washed with a deck stripper and the old deck stain is gone, it is necessary to brighten the wood using a wood brightener. The deck stripper will darken the wood and raise the pH level. To brighten the wood back to a natural state, and lower the pH to a more acidic level, will restore the appearance and give the new deck stain the best chance of lasting as long as possible.
A properly cleaned and brightened deck should be allowed to dry for several days before a quality deck stain is applied. Taking these measures and using a deck stripper and deck brightener before staining will give you much better and longer-lasting results.
