Hey everyone! If you’re like me, you love spending time outside on your deck. But we need to take care of it to keep it looking great and lasting a long time. One of the big questions I always have is, “Do I need to pressure wash before deck staining?” The short answer is it depends, but it’s often a great idea!
Pressure washing helps remove old coatings, dirt, and mildew so the new stain can adhere properly. But you also need to be careful not to damage the wood with the high pressure. If pressure washing seems like too much or if your deck is very old, there are other cleaning methods you can use. Keep reading, and I’ll walk you through everything you need to know so you can make the best choice for your deck!
Why Cleaning is a Must
First things first, why do we even need to clean our decks before we stain them? Well, decks, especially the ones made of softer woods like pine, are like sponges that soak up everything nature throws at them. Think about all the dirt, yucky mildew, and old, peeling paint or stain. If we just slap a new coat of stain over all that, it’s like trying to put a band-aid on a dirty wound. The new stain won’t stick well, the color might look uneven, and it won’t protect the wood for as long as it should.
What’s the Deal with Pressure Washing?
Okay, so what is pressure washing anyway? It’s basically using a super strong spray of water to blast away all that dirt and grime. It’s like giving your deck a super-powered shower! Pressure washing is great for getting rid of old, flaky finishes, mildew, and all the built-up dirt. It’s important to use the right kind of nozzle, though, called a fan tip, so you don’t accidentally gouge or damage the wood. Also, you can use special cleaners and a brush to get things extra clean.
The Good Stuff About Pressure Washing
Pressure washing is awesome because it does so much to prep your deck for staining.
- It removes all the dirt and yuck, so the new stain can grab onto the wood.
- It can blast away old, peeling finishes, which is super important for the new stain to soak in right.
- A clean surface makes the deck stain soak in better, which means a nice, even color and great protection.
- You may not even need to sand it if you pressure wash.
Watch Out! Pressure Washing Has a Downside
But before you go wild with the pressure washer, there are a few things to watch out for. If you’re not careful, pressure washing can damage the wood, especially softer kinds. You could end up with gouges or splinters. That’s why it’s super important to use the right nozzle and keep a safe distance. Also, remember that the deck needs to be completely dry before staining it.
When Pressure Washing Might Not Be Needed
Sometimes, you might not need to go all out with pressure washing. If your deck is pretty new or already pretty clean, you might get away with just a good scrub using a special deck cleaner, a brush, and a hose. Also, if your deck is super old or not in good shape, pressure washing might cause more damage. If you just want to use a sealant, a less powerful cleaning may be all you need. Plus, some deck stains, especially the semi-transparent ones, are easy to reapply without lots of prep.
Other Ways to Clean Your Deck
If you’re not into pressure washing, there are other ways to clean your deck. You can use an all-in-one deck cleaner with a pump sprayer, scrub it with a brush, and then rinse it off with a hose. There are also deck brighteners that can help make your wood look new again. And, if you have some tough stains, you can use non-chlorine bleach to get rid of them.
How to Pressure Wash Like a Pro
If you do decide to pressure wash, here’s how to do it safely:
- Safety first: Wear safety glasses and wear clothes you don’t mind getting wet.
- Test a spot: Try it out in a small area to get a feel for how strong the spray is.
- Use a fan tip: This spreads the water out so you don’t damage the wood.
- Keep a good distance: Don’t get too close or you might gouge the wood.
- Move smoothly: Go back and forth, following the direction of the wood grain.
- Apply a deck cleaner: Use a pump sprayer to apply it and a brush to scrub it, then rinse with a hose.
- Let it dry: Give it plenty of time to dry before deck staining, usually about 48 hours, or whatever the instructions say.
Extra Steps Before Staining
Before deck staining, it’s a good idea to check your deck for any loose or broken boards. Fix those up and then, if you need to, remove any tough stains that are left using non-chlorine bleach. I also think it’s a good idea to use a deck brightener before staining. It really makes the wood pop!
Picking the Right Stain
Now, let’s talk about stains. It’s important to know the difference between a sealer and a stain.
- Deck Sealers are clear or see-through and mostly protect from moisture, but don’t do much for sun protection.
- Deck Stains have color in them and protect from both moisture and sun damage.
There are different kinds of stains:
- Transparent stains let you see the wood grain and are easier to reapply.
- Semi-Transparent stains hide some of the wood grain but are more film-forming.
- Solid stains are like paint but they are permeable. Also, all deck stains are also sealers. Make sure to choose one with a UV-blocking agent to protect the wood from the sun.
Deck Staining Time!
When it’s time to deck staining, follow the instructions on the can. Usually, you’ll want to put two coats on the flat parts and one coat on the railings. Make sure you cover all the edges and joints so that the wood is fully protected. Then, let it dry before using the deck.
Keep it Up!
After deck staining, you’ll need to reapply it every few years to keep your deck in good shape. Decks around pools will probably need more frequent reapplication. Also, you may only need one coat when you reapply.
My Deck, My Happy Place

Frequently Asked Questions About Pressure Washing Decks Before Staining
Do I always need to pressure wash my deck before staining?
No, not always. While pressure washing is often beneficial, it’s not strictly necessary for every deck. A less intensive cleaning method may be sufficient if your deck is new or already quite clean. The need depends on the condition of your deck, and whether there are any old coatings, mildew or significant dirt.
What are the benefits of pressure washing my deck before staining?
Pressure washing effectively removes dirt, mildew, and old, peeling stains or paint. This helps the new stain adhere properly and penetrate the wood. It also makes the stain color more even and helps protect the wood longer. Pressure washing can also remove the grayed, weathered layer of the wood.
Can pressure washing damage my deck?
Yes, if not done correctly. Using too much pressure or the wrong nozzle can gouge or splinter the wood, especially softer woods like pine. It is important to use a fan tip and keep a safe distance from the wood.
What if I don’t want to pressure wash?
There are other methods! You can use a deck cleaner, a scrub brush, and a garden hose. You can also use a pump sprayer to apply the cleaner, then scrub it before rinsing. Deck brighteners can also be used to help restore the wood’s natural color. Non-chlorine bleach can be used to remove tough stains.
How do I pressure wash my deck safely?
Start by putting on safety glasses and clothes you don’t mind getting wet. Test a small, inconspicuous spot to get a feel for the pressure. Use a fan tip to spread out the water pressure. Keep a safe distance from the wood to prevent damage, and move the nozzle smoothly along the grain. Apply a deck cleaner, scrub, and rinse. Let the deck dry completely before deck staining.
How long does my deck need to dry after pressure washing?
Most sealants or stains require the deck to dry for at least 48 hours, or as specified by the product instructions, before coating it.
What should I do after cleaning and before staining?
After cleaning, inspect the deck for any loose or broken boards and repair them. You may also want to remove any remaining stains using non-chlorine bleach. Some may also sand the deck to promote better sealant penetration.
What’s the difference between a deck stain and a deck sealer?
Sealers are generally clear or transparent and primarily repel moisture but offer very little UV protection. Stains contain pigments that protect against UV rays and water and add color to the wood. Many products combine stain and sealer. Deck stains are also sealers, so applying a sealer on top of a stain is not recommended.
What type of stain should I use?
Semi-transparent stains allow some of the wood grain to show through and are easier to reapply. Semi-solid stains offer more color and hide more of the grain. Solid stains are the most opaque, like paint, but are permeable allowing the wood to breathe. For decks, semi-transparent stains are generally recommended for ease of maintenance.
Do I need to sand my deck before staining?
Sanding is not always required, but it’s often recommended. It removes old finishes, smooths the surface, and promotes better penetration of the new coating, improving both appearance and protection. However, it is especially important when switching from a solid to a semi-transparent stain.
Is pressure washing still needed if I choose to seal instead of stain?
Even when using a sealer rather than a stain, cleaning is still important for it to adhere properly. If you are not using a stain to add UV protection, keep in mind that a clear sealer alone will not protect from sun damage, and the wood will turn gray.
How often do I need to reapply the stain or sealer?
Clear sealers usually need to be reapplied every 1-2 years. Semi-transparent stains may last 2-3 years, while semi-solid products can last 3-4 years. Solid stains can last a bit longer, but have a higher risk of peeling. Regularly cleaning and inspecting the deck will help determine when it’s time to reapply. Decks around pools will likely require more frequent reapplication due to chlorine and splashing.
What if I don’t know what kind of finish is on my deck?
If you are unsure whether the existing finish is a paint or a stain, a deck stain stripper may be necessary and/or sanding.
Can I apply a sealer over a stain?
No, you should not apply a sealer over a deck stain. Deck stains act as sealers, so adding another sealer is not necessary and can cause peeling.
What are some signs that my deck needs to be re-stained or re-sealed?
Signs include graying or fading, mildew or mold, splinters, and water not beading up on the surface. A “water test” can reveal if water is absorbed within 30 seconds, indicating it’s time to reseal.
Are there any products that combine both stain and sealer?
Yes, many products on the market combine both stain and sealant in one application. Choosing a product that specifies both UV and moisture protection is important. However, applying a separate sealer over a stain is not recommended.
