Power Washing Tips

by RAD Products

If you don’t already own one of the many commercially available pressure washers for a homeowner, you can rent one from your local home center. Seek out the highest GPM (gallons per minute) machine they have available. This will make the job go considerably faster. The pressure is not important as high pressure should not be used to clean wood. A simplified analogy is to think of cleaning a dirty dish with a spray bottle (higher pressure/lower flow) versus using the water from a faucet (lower pressure/higher flow)

A pressure washer is a serious tool. Damage to property and person can occur if you are careless.

Damage from using high pressure can vary from splinters and raised grain to visible lap marks in the wood (these show up more after sealing) Just using a pressure washer without a proper detergent like Restore-A-Deck can also yield unwanted results. The pictures below show examples of a homeowner using no cleaner and just high-pressure water to clean.

damage

After you have allowed the oxygenating power of Restore-A-Deck to work its magic, it’s time to rinse. While you are at the home center renting your machine, try to have them give you a nozzle which will lower your effective pressure to 800 psi. If you do not have access to interchangeable nozzles, you will need to keep the tip of your gun at 12-18 inches from the surface.

Start the flow away from the wood surface and bring the gun slowly into the position to start rinsing. Start at one end of a board and walk your way to the opposite end keeping the nozzle the same distance from the surface the entire way. This will prevent lap marks. If for any reason you need to stop in the middle of a board, start the process from the beginning (at the end of the board) until you pick up where you left off. Take your time and always keep conscious of the distance between the spray tip and the wood. Be extra cautious on spindles.

walkin

When you are finished cleaning, apply your brightener and rinse. You may use the pressure washer again or a hose may be faster for you. No pressure is necessary during this final step.

Note: You may experience some small fuzzies that appear after the wood dries. This is normal to a small degree (especially on cedar). Often times these will dry up and fall away during subsequent rainfall. If you are planning on sealing as soon as is possible, these can be sanded away.

It looks like it going to rain for the next few days is it ok to leave it for a week or so until the weather is nice. Restore a deck stain take 48 hours to cure?

Neighbor had 1/2 in. Skinny dog ear . It’s graying, pine treated fence. We put up board on board 8 months ago. Still looks newish wood color. We powerwashed her fence with no cleaner just water it still looks grayish. But clean. I want to stain hers and ours but want it to blend. We used no cleaner because of plants. We did just a easy rinse on our newer fence.should I put something else on her at this point to make it look like new yellow looking wood like ours.?

We used the cleaner and brightener with a power washer. Is there such a thing as overpower washing? The deck still looks wet over 12 hours later. Should I let it dry and then mist it before staining? Or is it good to go?

I just stripped previous AC stain with restore a deck and I am planning to brighten and then use Restore-A-Deck semi-transparent stain after brightening. I just realized I have quite a few wood fuzzies. Do I need to sand these off for a nice finish or can I just brighten and stain?

i am using the solid stain/paint stripper on an old deck an using a pressure washer to remove the stain. Some is coming off OK but some is not budging. I’ve power washed every surface at least three times. Is it ok to recoat solid stain over the old stain that refuses to come off?

Hello,
The Pressure Treated decking on my dock was replaced last year and will soon be cleaned/brightened/stained for the first time with Restore a Deck semi transparent stain.  The bare wood was exposed to the sun last summer and fall, and then all of the decking was moved into a garage for the winter and spring.  
Should I plan on treating and staining both sides of the decking (water side and top), or would I be wasting my time and money on the bottom?

I have a large deck, is it okay to strip/brighten half one day and complete the other half the following day? How soon after can I apply TWP 100 if the weather is dry ( mid 60s during day)?

I just “finished” the stripping step and have been rinsing for an hour and it is still very slippery.  Is that normal?  Can I just move on to the brightening step?

Hi, we extended out our fence with cedar and kept the existing fence, that was here when we moved into the house. Seems like the older fence it is dipped pine but we are not sure. We are now wanting to stain the entire fence so it looks as cohesive as possible. Which semi-solid paint would you recommend and how should we strip/clean the fence so the colors blend in as much as possible?

If I use Restore-A-Deck semi-transparent and want to reapply in say 2 years, what would I have to do in preparation?  Could I just clean it and apply or does it have to be completely stripped?

Deck was previously stained with Thompson’s semi-transparent stain. I stripped and brightened deck last fall with RAD products but weather got too cold to stain. I want to put solid stain on rails and semi-transparent on floor. Can I just clean and brighten? Also, some boards are scratched due to dog’s nails. Should I sand?

Hello, I’ve been working on restaining my deck and came across your website. A sealer was put on part of the wood and it spotted. How would I remove this and what do you recommend going forward to brighten and stain. I’m interested in the one day method.

You think it will bring back some of the luster from when it was original because the sun has faded it some

I just purchased the stripper. I understand it is a powder. What is the best way to dissolve the power? Cold or warm water? How long can I store any unused stripper once I’ve added the water?

We installed an L shaped grade level deck that is 70’x 12’ on the long end and 12’ x 16’ on the short end with a 20’ walkway that is 5’ wide. The wood came from two different suppliers so there is a visible difference in the PT wood color. Also, due to time issues and design changes I’m adding posts and railing in the fall now. What do you recommend I do in the spring to match/blend the wood to stain and protect the wood?

I have two new decks built in summer 2018 out of PT Pine – was told to wait a year before treating, but it very unfortunately escaped me until recently, and I’m hoping with Western NY weather I’m not too late…

1. If we don’t get another dry day over 45° before snow hits, will my deck be ruined from then going thru 2 winters unsealed or is that not out if ordinary? Can I safely push that 45° at all to get it done?

2. Does it matter, application-wise, if one deck is for an above ground pool? (My neighbor saud they were told to seal every year vs. 2-3 due to chlorine?)

3. The prep we did was as novices and after we cancelled a professional doing it with SWilliams/BMlore brands and before we learned of your brand/website so not sure if we have to clean again and brighten now?… it consisted of a different brand of deck wash followed by a power washing day almost 2 weeks ago. We obviously didn’t do great at the power washing as there are still gray spots, but not sure if we have to now sand the missed gray spots off first? or if stain will cover it (thinking Cedar or Light Walnut). Sample photos attached.

4. Does the deck/stain darken over time and how much? I’d really prefer a light colored deck but Natural color seems too yellow to me, wondering how these look after a few years and coats.

5. Any other advice for this age of unfinished PT deck headed towards winter #2?

You just saved me SO MUCH stress! Thank you very much! One more question I thought of afterwards, my father-in-law had already added some MinWax wood filler to some knots & big splinters so that they wouldn’t collect water and I think I read on another thread here that RAD won’t color wood filler? PLUS one random board that leaks sap… Will I need to replace all those boards or is there another way to fix them so the stain covers evenly?

Just received my RAD cleaner and brightener today. My 30 year old cedar deck is dirty and grey but cleans up nicely with pressure washing alone. I’m thinking of pressure washing first; applying RAD cleaner; and then pressure washing again after the cleaner sets. Brightener applied as recommended after the second pressure washing. My logic is that the cleaner will work all the better if I first remove the worst of the dirt.

I have a 16 yo contractor’s deck of 60 sq ft, horizontal surface painted 5 yrs ago, peeled badly, so repainted w/same product (?) 2 yrs ago and again has peeled. Deck used only to access bird feeders so not too concerned about looks. Some ‘surface’ rot at ends of 2 boards, plan to remove most paint and rot w/my 2400 max psi, pressure washer, fill rot with epoxy if necessary and opaque stain everything, using Restore-A-Deck and RAD stain. I want to avoid sanding even if it means leaving some splotchy areas of ‘paint’ behind. Am I likely to need more than one gallon RAD opaque without running out and having to start over or should I order 2 gallons to start? I’m trying to make the project as painless as possible as I have NO help.

I just cleaned and brightened a cypress fence and it was rough sawn, so it has a lot of fuzzies like cedar would. Will this impact staining? Any tips for application due to fuzzies? Sanding is not feasible because of the shear amount of fence pickets.

And it’s old deck, not new wood, thus the 2nd coat. Already used stripper and brightener/neutralizer.

I ran out of RAD stain while doing over 1000 sq ft of decks – one separate deck area just received a single coat (these deck soaked up 10 gallons like a sponge which is why I’m short…) I’ve just ordered more, will I be OK applying the second coat when it arrives in a few days? I know the instructions are to do the second coat 20-40 minutes after the first, but that’s not possible…

My Deck is 300 sq. ft. including steps. I used Pressure Treated wood (spruce, pine, fir or SPF in Ontario) and it was installed in the summer of 2018. Left to over winter and not treated with anything as I wanted it to weather for a few months.
What do you suggest for treatment now, and how much stain would I need? Is RAD acceptable in Ontario?

Ours is a new (9 month old) 2×6 PT deck. We are planning on waiting until a full year is up to stain. The wood is not black or dark, so do we need to do the cleaner and brightner and pressure washer?
