Armstrong Clark Oil Based Wood Deck Stains

New Decking and Armstrong Clark Stain

by Armstrong Clark Wood & Deck Stains

Armstrong Clark is a penetrating oil based stain that will soak deep into the wood grain offering protection from UV graying and water. The advantages to a penetrating deck stain is that they will not peel but rather fade over the years. The key though is proper prep before applying your AC especially if your wood is new.

Key Takeaways
  • New smooth wood should not be stained immediately after install; wait 3-4 months for transparent or semi-transparent colors.
  • Use the Restore A Deck Cleaner and Brightener Kit to prep wood before applying Armstrong Clark Stain.
  • Rough Sawn cut wood can be stained right after install, as long as the wood is clean and dry.
  • Armstrong Clark covers 150-300 square feet per gallon on new wood; hardwood decking spreads farther at 300-400 square feet.
  • Maintenance coats are needed every 2-3 years; Armstrong Clark has a shelf life of 1 year opened and 3 years unopened.

New “smooth” wood should not be stained right away with Armstrong Clark. A few things need to happen first:

  • The wood should dry out in the climate
  • Exposed layers of wood cells should oxidize slightly
  • Mill glaze needs to be removed
  • Prep after waiting will remove both oxidation and mill glaze

New Decks and Armstrong Clark Stain Tips

The best advice is to not stain your new smooth wood too soon after install but follow these steps:

  1. Install wood and let sit outside for 3-4 months or more if using a transparent or semi-transparent color. If using a semi-solid color, you should wait 12 months.
  2. Once the wood has been exposed, use the Restore A Deck Cleaner and Brightener Kit for prep.
  3. Let the wood dry for 2 or more days after prep.
  4. Apply 1 coat of the Armstrong Clark Stain. Do not over apply.

To maintain your new coat of AC you will most likely need to a light coat in 12-24 months to just the floors or horizontals surfaces. In the future, you will need to reapply AC every 2-3 years for most scenarios or as needed based on your particular traffic and weather.

Important Note: Rough Sawn cut wood can be stained right after install as long as the wood is clean and dry.

How to Calculate Square Footage

Deck Sq. Footage

Flooring Length x width =?

Railing Length x height =?

Steps Width x Depth x #of Steps =?

Add up all 3 for the Total Sq. footage.

Fence Sq. Footage

Length x height =?

Multiply x 2 for both sides = Total Sq. Footage

Coverage Rate for AC Stains

The specified coverage rate for Armstrong Clark is 150-300 square feet per gallon for the first coat on new wood. From this, and from measuring the surface you can calculate how much stain you need. For more aged wood you could easily factor in some extra stain. On newer wood that is still smooth and dense, you probably are not going to use as much.

Note: Hardwood Decking spreads about twice as far. 300-400 sq feet per gallon and only 1 coat.

For maintenance coats you are not going to use near as much stain as you did initially staining bare wood. There are just way too many variables to know the exact coverage rate. There is really no way of knowing exactly how much stain you will need. It is better to buy more than you need than to not have enough. You can always save left over stain for next time. Armstrong Clark has a shelf life of 1 year if opened and 3 years unopened as long as the can is properly resealed.

I used your chestnut stain on PT deck boards & PT 2×6’s for my front porch a couple years ago. Waited maybe a month after purchasing the material to stain before laying it down. It’s held up amazingly since applying. Porch floor does have a roof, although exposed to hot afternoon sun & the steps are exposed year round with the winter snow sitting on them till spring. The steps will need a refresh this fall. Looking to rebuild my rear deck railings with a darker brown over PT 2×4’s. Why wouldn’t the oxford brown or expresso stain work on lets say a month old PT material??

I aged, cleaned and then stained my new deck 1 year ago, using your Rustic Brown. Good results. In this year, our 3 dogs have worn down the stain on the trafficked horizontal areas of flooring and steps. We have 3 very active dogs. New railing with verticals have since been installed from the base of the deck steps, going alongside concrete steps to our driveway. I have hoped to re-apply stain directly to the deck floor and steps and leave the verticals as-is. I know that the new railing/verticals need cleaning and staining, but am unsure about how to address last year’s deck stain.
Thanks very much for a great product.

Bob, how’s that rustic brown look on PT wood? Can’t get an accurate fix on the color from the pictures on this site. I’ve used the chestnut, & it’s too light of a brown for my current application. Guess only way to know for sure is to get a sample🙄.

I’m slow getting back to you. I really like the rustic brown. We had a little rain yesterday afternoon, so am waiting to see how it matches last year
The color\tint of our deck is pretty close to this photo on the AC site, but is less reflective – more flat. It’s PT yellow pine.

We just had a screened-in porch built on the back of our house. Pressure-treated, MC = below 11%.

  1. Should we wait until more moderate temps in the fall to apply?
  2. Do you sell small sample/test amounts?

Before I saw your response, I put a coat of the RB on an independent section of the mahogany deck. I will proceed with the rest of the deck using the Hardwood product. Should I do anything about the section i already did or just leave it?

After hours of research I like your product. Background is the painter put a indoor stain on my deck…..Made a terrible mess with some of it not drying etc,,,,,,It has now been sanded off and it is pine wood. I am sure it needs to be washed with a product etc. before another stain is used. Looking at Rustic Brown or Natural Oak… Dont want red tones ot it to be too dark but brown…..Any advise…..Plan on using semi transparent oil based stain.

I am having a new cedar fence installed – does the information above apply to new wood of cedar fences as well as decks? How long should I wait before I seal and what is the best application for a board on board cedar fence with a mission lattice? Does the lattice change the calculation of square footage? Is there mill glaze on newly installed cedar fencing?

I would like to use your semi transparent oil based stain on a knotty pine smooth ceiling tongue and groove and rough-sawn posts. Your instructions say rough-sawn can be sealed immediately while smooth surfaces should wait and then have your cleaner brightener product applied. I expect that step is not appropriate for ceilings where you wouldn’t want to pressure wash it. Please advise. This is new construction. Thanks

Thanks! On the back porch I’m staining pressure treated lumber…some rough-sawn and some regular pressure treated 2×12’s. Are those 2×12’s in the same category as the tongue and groove in terms of prep? Also, I put some sample stain on the tongue and groove and like the color. I’m a little concerned that opening the pores will change the color to something I may not like. What happens if you skip that pore opening step? I’m using Rustic Brown on that back deck. I have the same concern on the front patio. I like that semi-transparent chestnut color I’m seeing on the raw tongue and groove. I’m afraid using that cleaner/brightener will change the look.

Hello. I have a pressure-treated pine deck that was completed in May of 2024, so 2 years ago. I will be using the restore a deck cleaner and brightener, before staining with semi-transparent Nat. Oak. I was planning on 1 liberal coat, wiping away any leftover standing/shiny spots the next day. But, I wanted to check based on the age of the wood if 2 coats would be necessary or ideal. Also, is the 48 hour drying period before staining absolutely critical? I’m asking because I have a large tree above half of my deck, which attracts lots of birds and therefore bird droppings on my deck. At minimum, I anticipate having to hose down and lightly brush off any bird droppings that have accumulated after cleaning/brightening the evening prior to staining or possibly even first thing that morning. The deck gets a ton of sun, and I’d be starting with the railings and lattice, so the deck boards would have an opportunity to dry, so I was hoping that would be ok. Any suggestings?

Last summer I installed a new deck of kiln dried cedar. We were racing against winters arrival (October here in Upper Michigan) so after 6 weeks of it being exposed to the elements I did the restore and brightener and lightly sanded it to remove mill glaze although I think it used too high of a grit, then stained with AC Amber. It was beautiful.
After the long winter it now has areas where it looks weathered and like there is no stain or has significantly faded. I did a water test on it and within 3 minutes the water was absorbing in.
Apply another coat? Or Restore and brightener and then restain?

What’s causing this? Tigerwood 3yr old. Used defy restore, sanded boards, used defy brightner. . Rinsed deck for over 30 minutes, no soap bubbles. Even rained. Waited for boards to have no moisture. Front deck same way..tried an area with no brightner…same… goes on great.. looks great.. then as it dries yellow streaks appear. I put this on really light coat.. looks like i can clean it and put another coat on? Wood has zero finish.

You say to install wood and let sit outside for 3-4 months or more if using a semi-transparent color. How do you know if more sitting time is necessary? I plan on replacing the cedar deck surface in about 6 weeks and staining with the Cedar or Natural Oak. I have a moisture meter so does it come down to making sure reading is in the 15-19% range?

This time around, I bought myself a digital wood moisture meter and after letting the boards sit in my garage for one week, they are already sitting at around 9 to 10% moisture. The boards that I already installed earlier this week are already drying back and creating gaps on the deck. It seems like it is plenty dry. I’m just wondering how much more should I let it get weathered?

YIKES! We are planning on replacing a 2200 sq ft deck with KDAT decking, in reading the material on KDAT it says to acclimate the lumber for aproximately 48 hours to your climate then give it one coat encompassing the entire board and ends. We were planning on using Armstrong-Clarke stain but in reading your advice to Marcus on waiting 1-2 months I’m confused. I don’t have and enclosed area to acclimate the boards and keep them dry for 2 months. They will be on my covered porch. In my reading and giving the 1 coat, I also read we should stain the deck within 1 week of completion. So what would the answer be? Your stain directions or the lumber?

Hi
I just need a little clarification. Our Ohio spring weather has been a bit fickle.

So my newer pt pine deck is ready to be stained after following all prep guidelines. However our spring weather is making this a challenge. After a day of rain we will have 3 good days of sun. Although temps have dropped from the 80’s into the 50’s. On the 3rd day we will have temps in the 70’s which I would like to stain.
However the next day there is a chance of rain all day with chances starting around 4am.

Can I take the chance to stain? It will have around 12-14 hours of dry time with temps in the 70’s.
Thanks

Hi! I used semi trans Rustic Brown 6 yrs ago in my white pine fence. Need to restain this year. I made note I used about 12 gallons in the initial staining process. I plan to clean and brighten before restraining but do you think I need to order another 12 gallons or does a restain typically need less since there is already stain in the wood? Prices have gone up substantially since then so don’t want to over-buy. Appreciate your help!

Hi. I’m about to replace my current composite deck boards with a grade 2 cedar deck board a local lumber yard has. the cedar I was shown at the yard was stored outside so does that account for the time frame I would wait before staining because its acclimated already? I live in Boise,ID. elevation around 2700 above sea level. I’d like to know the recommended months to stain or if it matters because the deck boards have been outside for months already, and what stain you recommend using.
Initially I planned to get the deck boards into shop (regulated heat around 70 degrees) then light sand all (120grit), spray stain both sides. then the boards would sit in shop for a month or so before installing. then install on deck and spray second coat after installed. appreciate the advice/help

Hi. Finished restoring a mahogany rail system. Stripped Sikens Cetol from certain sections and awful BenMoore Harbour coat water based from other areas w/DRP stripper+[GREAT STRIPPER. used citrus stripper on a grage door, what a MESS]. Water based stain did not protect the wood at all, terrible product. Sikens Cetol worked but <VOC(s) lead to <time bef/maintenance coat required bec/mildew infiltration behind stain. So switched to Armstrong & Clark aft/>research. A&C easier to brush on than Sikkens and 1 coat looks great. Process. 1. cleaned w/sodium percarbonate TSP and Oxi-clean. 2. stripped w/Deck Restoration Stripper +, sanded w/60-80grit. 3-4 day dry time. Then A&C!

Wanted to confirm timing for staining. I have a new IPE deck and understand I should wait 12 months before staining. I also have newly installed vertical, smooth western red cedar and understand that if I plan to use A-C semi-solid stain, I should also wait 12 months. Correct?

Finished my first Armstrong staining today on my back deck and stairs. I am putting together notes for next year on how I should do the next staining on the horizontal surfaces.
1. Do I use Restore and Brightener after the first year before staining again?
2. If you recommend both or either the Restore and/ or Brightener, do I use them at full strength or 1/2 strength?
3. Any other recommendations for year 1.
4. For years 3-4 (assuming I restrain in year 1), do I use the Restore and Brightener just like I did for the initial application I just finished?

Thank you for your assistance.

We replaced all the boards on our 4th floor, full-sun, south-facing balcony 4 months ago with pressure treated pine. It is late October in Chicago. Am I better off waiting another 7 months until next Spring to stain with semi-tranparent AC, or risking less-than-ideal weather to get it done now before winter comes?

I assume a semi-trans stain will not hide the green ink stamps and I should sand them off. Should I sand the whole balcony to get a more consistent surface? If I’m not going to stain until Spring, should I wait until then to sand?

Lastly, our balcony sits on top of the roof over the 3rd floor balcony of the condo unit below ours. There is a drain in between our balcony boards and the downstairs neighbor’s roof below, but the drain isn’t placed right, so rain (or chemicals) may sit on the roofing material for a while. Will any of the cleaners and brighteners you recommend for prepping the bare wood damage the rubber-like roof membrane underneath our balcony? The balcony is also over a busy sidewalk, so I am worried about stray chemical splatters hitting pedestrians below. Would I be better off foregoing the cleaners and brighteners and instead sanding with 80 grit to prep the wood for stain?

I had my new PT pine deck board fence built two months ago. It is kiln dried. I am only now removing the mill stamps using the recommended sanding method with 80 grit paper and a palm sander. There is a noticeable difference in color as the sanding is leaving light patches on the wood. If I let things age for another two months and then use the brightener before staining, will the patches go away?

I stained my new deck very successfully with all of your directions in 2024. I did another round this fall–full restore a deck treatment and then staining. Did the two sides first, then the front. The sides came out great. But on the front, despite weather reports to the contrary, it rained within an hour of finishing applying the stain. Now that things have dried out, i’m not too happy with the front–it doesn’t look like it got as much coverage, or as even coverage as the front. Can I simply add another coat of stain on a sunny day or do I have to go back to the restore a deck steps first? Thanks!

We used restore-a-deck (R-A-D) semitransparent stain two years ago. It peeled in some areas after two years, so I have been removing it. I used R-A-D stain remover, then the brightener. I had to sand all the deck because, even though treating it twice with the remover in places they did not come off, stain remained throughout the deck, plus the power washer rough up the surface too much. I am now ready for new stain and am looking at Armstrong Clark because do not ever want to go through this grueling process again!

Questions:
1. Under my deck is a beautiful storage shed built two years ago, never stained. Before stripping the deck above, I cleaned the boards of the shed to try to avoid running and drip marks from above. When I brightened the deck, I also brightened the shed boards. Unfortunately, some light overspray from the stripper has made light dots on the shed wood. How do I restore the affected boards? On a test board, sanding did not do the trick.
2. It has taken several weeks to do all of the above. Since I sanded, do I need to do something more to prepare the wood for your stain.

3. Confirming: if I keep up with cleaning and putting on a coat of your stain again each year, I avoid all that I have had to do to this year with removing the former stain. Yes?

I finished stripping the old Penofin stain my 20 year old redwood deck. It should be ready for the Armstong stain 10 days after I apply the brightner & neutralizer. I will need to replace two 20 ft. boards. How long should I wait before staining the new boards. Would sanding the new boards or using a some chemical like a brigtner help accelerate the weathering before staining?
I know the new board wont match perfect but my only other option is to use the solid deck stain.
Any advice is appreciated.
Thanks

We had our deck retopped with pt pine. I plan on using AC semi transparent instead of Ready Seal that I used previously. There is a wood bench that is mounted on the deck that was not replaced and is stained with Ready Seal. I was unsuccessful using your stripper on it. I think my options are:
Continue to use Ready Seal just on the bench
Sand the bench and then apply AC stain
Apply the AC stain on the bench with no other preparation.
Advice, please

Help! Our cabin deck is approximately 700sq feet we have already power washed it and waiting a few weeks to sand. The deck is Douglass Fir and due to its size we need to extend its life as much as possible as replacing it not an option at the moment. We cover it with a tarp during winter to help extend its life. We are thinking of Dark Walnut color stain, is that a one coat application or will Doug Fir require more.?
