There are a few decisions that need to be made when staining a deck and we will help you figure out what supplies and technique is right for your deck and situation. These penetrating deck finishes, at least the water-repellent sealers, may have a shorter service life than paint, but they are more easily renewed. Remove mildew by applying a cleaning solution of four (4) ounces of 100% powered Tri-Sodium phosphate (TSP) or phosphate-free substitute with one (1) quart of liquid bleach and three (3) quarts of water, to the wood surfaces with a garden sprayer or a heavy nap roller cover. For North Texas homeowners, it pays to be extra-vigilant in the care and maintenance of your pine or cedar fence.
The use and handling guidelines for treated wood reflect common sense and good safety practices for handling any wood. The tank is then filled with the preservative under high pressure, forcing it deeply into the wood. Typically formulated with UV protection and chemicals that retard the development of mold and mildew, these products will protect wood for up to two years. A deck that is regularly treated will look better and outlast an unfinished one.
Verify that the sealer has a few key properties: 1) waterproofs, 2) stops the growth of mold, mildew and fungi, 3) protects the wood from wood-destroying insects. It is advised to wait until the wood is dry before applying the stain, approximately one or two months after completion of the project. Our fence staining services include cleaning, staining, and sealing outdoor structures such as fences, arbors, decks, and play sets. When kiln-dried wood isn’t an option and you use air-dried or wet lumber, sealing all sides of the board is a recommended best-practice. If you plan to use an oil based stain, you should wait at least two months before applying the stain.
I used the Behr semi solid stain on a pressure treated deck….AND…..on a Gazebo roof made of cedar fencing. That’s about all there is to it, it is not rocket science, but you need to pay attention to certain aspects of what you are doing when staining a pressure treated deck. If you are unsure and the board is very flat to begin with, go with your gut and put the best looking side of the wood up. Based on the conflicting information out there, you’ve got a 50-50 chance of being right! The wood usually returns to its original color after cleaning with this type of cleaner.
It is therefore very important to apply a preservative to pressure treated wood to slow down the drying as a way to inhibit shrinkage. I have always custom-tinted the Behr stain, but I tried a small sample of Cabot’s Australian Timber oil in the Mahogany Flame and it looks great.
