Question: How Long To Wait To Stain 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.

How long should I wait to stain my deck after power washing?

A basic rule of thumb for DIY deck builders, homeowners, and professional contractors is that roughly 48 hours is an adequate drying time for a newly washed deck.

Should you pressure wash your 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.

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.

Can you stain after pressure washing?

As a general rule, you should wait at least 24 hours to stain a deck after power washing. You want the deck to be completely dry before you put any sort or coating on top. If you don’t, you’ll trap the water underneath the stain and the finish will look blotchy and uneven.

How long after power washing can you seal a deck?

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.

How do you know if your 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.

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 is the best time of year to stain a deck?

The best time to stain your deck is either the spring or the fall. If you stain your deck in the summer, make sure you do it out of the direct sunlight. Applying a deck stain in direct sun will cause the stain to dry to quickly and can result in premature stain failure.

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.

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 long should pressure treated wood dry before staining?

If you buy ordinary pressure-treated lumber from a home center, however, you’ll have to wait anywhere from two to three days for the wood to dry sufficiently before you can apply a water-based semitransparent protective stain.

What if it rains after I power wash my deck?

If it looks like rain, cover the deck in a tarp to avoid extra seepage. If standing water is left after you power wash and scrub the deck, squeegee it off the surface of the wood or soak it up with towels to avoid soaking into one place.

How many coats of stain do you put on a deck?

Should I power wash my deck before sealing?

Pressure washing is the best way to prepare your deck for sealing. This is necessary to remove any splinters or fuzzy patches that pressure washing can cause. The easiest way to do this is to use 80-grit sandpaper attached to a pole sander.
