Can I power wash my deck before staining?
There is a common misconception that just pressure washing a deck prior to staining is all you need to do in order to prep your deck for stain. Pressure washing can help, but if you want your stain to last, using a good deck cleaner and brightener on the deck prior to pressure washing will provide you the best result.
How long do you have to wait to stain a deck after power washing?
After a deck has been power washed it will have some retained moisture within the wood. It’s important to let the wood dry thoroughly so none of the water that soaked into the wood gets trapped under the stain. In perfect drying conditions, 48 hours is enough for the wood to get to where it needs to be before staining.
Can you pressure wash and stain a deck in the same day?
DPI Pressure Washing recommends you wait 72 hours following cleaning to stain your deck. Always inspect the wood before staining it. If you see moisture or some swellings still apparent in the fibers, wait another day or two. Remember that staining a wet deck will result in an uneven finish at best.
Do you have to seal deck after power washing?
After completing the deck power washing, wait 24 to 36 hours before applying sealer. If the weather is cool or humid, wait 48 to 72 hours. The deck must be thoroughly dry to ensure deep penetration of the sealer.
Why you shouldn’t powerwash your deck?
Wood decks are especially vulnerable to power washing, because the pressure exerted by the power washer can lead to splintering. If there is any area on the deck where the wood is already beginning to split apart, power washing it will exacerbate the problem and cause the split area to expand.
Is it better to sand or power wash a deck?
DO sand your deck before sealing. At that point, lightly sand the surface to remove splintery or fuzzy patches caused by pressure-washing the deck. A pole sander with 80-grit sandpaper will suffice; a power sander is overkill. Then seal the deck to protect from cracking, cupping, and warping.
How many dry days do you need to stain a deck?
You will want to set aside a minimum of two days, including drying time. If your deck needs to be power washed, or if the boards on the deck need replacing, you may want to set aside another extra couple of days. Be sure to have all of your supplies ready well ahead of time.
What if it rains after I stain my deck?
If it rains within 48 hours after you apply the stain, the water will soak into the wood pores and try to displace the stain. This will result in a splotchy surface rather than an even tone. If it rains right after you apply the stain, the stain will peel and flake off.
How many coats of stain do you put on a deck?
The general rule of thumb is to apply only as much deck stain as the wood can absorb. Typically this will be 2 coats, unless your dealing with extremely dense hardwoods which may only be able to absorb 1 coat of wood stain.
What PSI is needed to power wash a deck?
For cleaning a wooden deck, you’ll be best served by using the lowest pressure setting that’s still effective. For soft woods like cedar or pine, this is usually about 500 to 600 psi. For harder woods, it can go up to 1200 to 1500 psi. Choose the right tip to use as well.
How do you clean deck before staining?
How-To Prepare a Deck for Staining Thoroughly sweep the deck to remove all leaves and other debris. Liberally apply cleaner using a roller or pump sprayer (wear protective equipment to avoid contact with skin and eyes). After 15 minutes, work the cleaner into the surface using a stiff synthetic-bristle brush.
How do I know if my deck is dry enough to stain?
To determine if pressure treated wood is dry enough to stain, try the “sprinkle” test. Sprinkle water on the wood: if the wood absorbs it within 10 minutes, plan to stain as soon as possible. If the water beads or pools on the wood surface, the wood needs more time to dry.
What do you put on a deck after pressure washing?
Applying Sealer Your deck needs at least two full days to dry after you wash it and before you seal it. While you can always apply sealer with a paintbrush, it’s faster and easier on your knees to use a roller or a sprayer.
What should I do after pressure washing my deck?
After you’ve power-washed the entire deck, rinse all of the wood with plain water to dilute and neutralize the stripper. If there’s still debris trapped between deck boards, such as leaves or twigs, remove it now (Photo 3).
