Armstrong Clark Oil Based Wood Deck Stains

Armstrong Clark Staining Instructions

by Armstrong Clark Wood & Deck Stains

Choosing Armstrong Clark Oil Based Wood Stains will ensure lasting beauty and protection for all your exterior wood surfaces. Backed by five generations of experience in oil-based coatings and cutting edge technology, Armstrong Clark Wood Stains will not only meet your wood protection needs but far exceed them.

Key Takeaways
  • Measure all areas to be stained, including floors, railings, spindles, and steps, to determine total square footage accurately.
  • Armstrong Clark Deck and Siding Stains come in many colors; actual results vary based on wood type, age, and porosity.
  • Properly prepare and clean wood surfaces using RAD Wood Cleaner or Stain Stripper, then allow 1-2 days drying time before staining.
  • Armstrong Clark Deck Stain can be applied with a roller, brush, stain pad, or sprayer, even in direct sunlight on hot days.
  • Coverage is approximately 150-250 sq. ft. per gallon for the first coat; buy extra stain since it has a shelf life of 1-3 years.

Determine the square footage area of the surface you plan to stain. On decks be sure not only to measure the floor but also railings, spindles, steps and all areas that you are planning to stain. Armstrong-Clark Deck and Siding Stains will cover approximately 150-200 sq. ft. per gallon depending on age and wood porosity.

The Armstrong Clark Staining Instructions

Armstrong Clark Deck and Siding Stains come in many different colors and tones. Keep in mind that the actual color results can vary depending on the type, age, condition, and porosity of the wood. Color samples are available if needed.

Prior to using any of the Armstrong Clark Wood Stains it is important to prepare the wood surface properly so the stain will perform as expected. See the RAD Wood Cleaner or Stain Stripper products for properly cleaning the wood surface prior to staining.

Allow the wood surface to dry 1-2 days after it has been cleaned and prepped. Be sure no rain is expected on the day of staining and for 3-4 hours after application so the stain can cure properly.

To apply Armstrong Clark Deck Stain you can use a roller, brush, stain pad, or airless sprayer. Mix the stain thoroughly prior to use. Unlike other stains, Armstrong Deck Stain can be applied in direct sunlight and on hot days. If the first application of stain penetrates within 30 minutes another coat can be applied for added protection.

If applying by sprayer, use a roller or brush to go over the sprayed areas for a more even appearance. After 24 hours use a dry rag to remove any remaining puddles or glossy areas.

Armstrong Clark Wood Stain is environmentally friendly and does not contain an offensive odor. It is easy to apply and very user-friendly. Enhancing the appearance of your deck and giving it lasting protection is the best investment you can make and Armstrong Clark Oil Based Wood Stains makes it easy.

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 150-250 square feet per gallon for the first coat. Second will apply at 200-300 per gallon. This averages to about 100-125 sq. feet per gallon for 2 coats wet on wet. 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.

Is it a good or bad move too stain the tongue and groove profiles of Douglas fir? If stained would that cause a less tight fit compared to raw wood?

For sanded wood you guys recommend single coat?
My deck is sanded with 60g. And cleaned with brightner.
Going with semi transparent.
My question – what if some parts of deck drinks more pain? Still stick with single coat?

Hi am sanding my deck with 60g. It’s older deck but after sanding wood is looking bright. I did clean and applied brightner before sanding. I am planning to apply semi transparent Armstrong stain.
Question.
Do I need to apply brigtner after sanding? Is it must or nice to have?
Can I just blow off using blower and apply stain after sanding?

Thanks for response. I’ll strip and brighten it. Hoping to stain soon. Temps in TN are in the 90s. I understand that your product can be applied in warm temps. Anything I should be aware of. I assume the 2nd coat would need to be applied sooner since may dry quicker?? Do you recommend waiting for cooler temps?

I have milled rough cut red oak and it has dried 9 months on a pole barn. Have used Sherwin-Williams Williams timber oil before and have liked it. What product of yours would you recommend? I have heard the SW timber oil isn’t the best on red oak.

For a maintenance coat of the same AC semi transparent, I see that surface prep calls for RAD cleaner. Should the RAD brightener be used after the cleaner even for maintenance coats? Or is only the cleaner required? If using the brightener after the cleaner is not required, would it affect adherence / bonding one way or the other either positively or negatively?

About Armstrong’s ‘reply’ to my questions, who mentions, “Best at 100 or below.”

Does this refer to a 100 surface or ambient temperature, e.g., wood temperature?

Sorry for the duplicate comment below, but when I try to use the reply button, it doesn’t seem to work.

Please advise.

Armstrong’s directions state that Armstrong Clark Stain can be applied in direct sunlight up to 110 degrees. However, under those conditions, the wood surface could reach about 130 degrees within minutes.

Is application still recommended if the wood surface reaches 130 degrees or higher?

Please advise.

We’ve had a bunch of rain, predicted and random. We have no used cleaning and brightener on the deck twice trying to remove the previous water based stain. I plan to rent a random orbital sander and finish with a 60 or 80 grit to remove the little bit of previous stain. My question is, after sanding, since we have cleaned and brightened twice already. Do we need to sand and then clean/brighten again before applying the semi transparent oil based stain? I was planning to use a shop vac and leaf blower to get all the particles out from sanding. I didn’t want to apply too many chemicals by cleaning/brightening for a 3rd time unless necessary. Thoughts?

I have a 4 yr old covered pressure treated pine porch that gets some sun during the day. We’re at 6K elevation in Montana so UV and weather is harsh. I just removed Valspar by sanding it off (I didn’t want to use stripper to avoid any streaks or splashes on concrete below or log walls). I used 100 grit and wish I’d read these comments earlier. I want to use either transparent Natural Tone or Semi Transparent Cedar. Should I do 1 coat or 2? Do 1 coat now and another in the spring?

I have stained my deck previously (2020) in the Woodland Brown semi-solid stain without a problem. I recently hired someone to restain the deck in the same color. After drying I have large areas where the stain looks an orange/rust color and other areas that look like the woodland brown color. Could improper mixing of the stain have caused this and how can I remediate the problem? Thanks Gail

we have had over a week of rain. Before it began I stripped my cedar deck , see below, and sanded a few spots that I must have spilled the original stain,(Defy Extreme) on and have just a little stubborn spots to be fully stripped. When we finally get dry, hopefully end of week, I plan to sand with 80 grit , apply brightener, and when dry (I hope!) stain with AC semi trans cedar.
The deck boards are 2X6 cedar, pretty clear, 15 years old at least, I bought used decking .
They have cleaned up well. Should I be looking to do 2 coats, wet on wet? If so, how long to wait between coats? Same day? And should I wipe down between coats and after final?
I believe I have a 5 day sunny window end of this week.

I want to use Armstrong Clark Semi-Transparent Amber stain on a 6 month old Ipe outdoor dining set. Purchased in November 2025, and although I covered it over the winter, the springtime sun here in middle Tennessee has already bleached the wood, especially the horizontal surfaces, to a very pale gray-beige. I have tested the stain (one of your samples) by brushing it onto a leg under the table (in shade), which looks very good. Question: your stain directions provide lots of guidance on applying your products to decks; what’s different about using it for furniture? Your baseline instructions include this: “If the first application penetrates within 30 minutes, another coat can be applied for added protection.” How do I know if it has “penetrated”; is it dry to the touch? Any other guidance for furniture stainers like me? I’m ready

I have fo 12 years been using WP 1500. I switched 2 years ago to Defy Extreeme looking for a easier to apply sealer. However this past winter we had more snow and ice in Maryland than usual and I found shoveling it off scraped off the coating which was on top. I did use a platic shovel but still looks terible and no longer sealed. Thinking to go back to an oil and read good things about Armstrong Clark.
I am confused about how to remove the Defy. I had thought to sand it off, but see comments about that making oil penetration hard. So do I strip deck with Restore a Deck, then sand what stays on, then use brightener? I built the deck 35 years ago. This red cedar decking I bought used 15 years ago and installed and cleaned then put TWP on it. It took forever to dry so I am Hoping the AC will dry faster an absorb in well.

I am going to use AC semi transparent stain on my 500 square foot deck. I have pressure washed my deck. There is a small amount of previous stain remaining on my deck applied 10 or so years ago. My plan was to use a stripper to insure all remaining stain is removed. Then I am going to use a brightener shortly after. I also want sand my deck additionally, beyond the steps I have mentioned prior to apllying the stain. I purchased 5 gallon for this project. Let me know is sanding would be a worth while step.

I have a 600 sq ft deck with cedar boards. The deck is at least 10 yrs old and the previous stain has been completely removed. The wood is in fairly good shape. I’d like to apply semi transparent driftwood stain to it. I did already sand with 100 grit however. Will that affect applying the stain? Also how many gallons do you recommend? 1 or 2 coats? Do I need to brighten with oxalic acid? Thank you

Hello,
I finished the stripper gel process but there are some small areas where the stripper would not work. Can I sand those areas before applying the Amber stain?
Do I need to brighten the deck before staining in areas where the gel stripper was not needed?
Thanks.

Have a three-year old cedar deck. First year sanded, then stained with Cabot natural ATO semi-transparent. Second year sanded completely again, failed to use a brightener, and stained with ATO again. Stain faded badly within four months. Now looking to move to Armstrong cedar semi-transparent. Deck still has some faded ATO, and some areas where the stain is more intact. Just purchased RAD stripper/brightener. Do I need to do any sanding again, or should the RAD remove the ATO if the stripper is applied correctly? If sanding is needed, that step would be after stripping and before brightening, correct? Is any cleaner needed as part of the process? Want to ensure the surface is most prepared for the Armstrong. And if I don’t sand, will AC require two coats? Also, the fascia boards are rough side out cedar. Will RAD strip that as well? Thanks!

One additional question. If I’m using 2-3 gallons, should those be mixed together in a 5 gallon bucket prior to starting the staining process to ensure no differences in color?

We live in Central Oregon and have a covered porch and an exposed deck both 10+ years. Our exposed grey cedar deck needs to be re-stained but the wood is still good (checked with a deck contractor). To make the porch and the deck have a uniform look, we plan to sand the entire area before using an Armstrong-Clark semi-transparent stain. Our question: Should we apply a brightener like Restor-A-Deck after sanding and before applying the semi-transparent stain OR should we just apply the stain directly to the sanded deck? If a brightener is recommended, can we use a different product like Benjamin Moore Woodluxe Brightener and Neutralizer? One other question, would you recommend applying one or two coats of semi-transparent stain?

I saw a comment below, saying to not apply a second coat “because you sanded” during prep. I have an 18 month old pressure-treated pine deck, never been stained or treated. I’ve just sanded it then cleaned it. I have AC Semi-Solid stain (Expresso) and was planning to do two coats (for deepest possible color) using wet-on-wet method. But since I sanded, does that mean I should not apply two coats?

Frank Alexander

Thanks. And just to clarify… I sanded with 80 grit paper, which I understand reduces wood pore clogging. Then afterwards I scrubbed the wood using a homemade 1:3 diluted bleach solution & dish soap as specified in AC’s product data sheet. I heard such cleaning not only removes sanding residue but somewhat “re-opens” the wood pores. Does this cleaning-after-sanding make it possible to apply two coats of semi-solid stain, wet-on-wet, if I want a darker final color? (I can test the second coat penetration on a not-noticeable area of the deck — but sure don’t want to mess up this project!) Thanks again.

It took 5 gallons brushed on. (I used all the stain I could buy from the store.) Do I need to apply a second coat? If so, I don’t have another window without rain for a few days at least.

I have almost half of the 5-gallon bucket of semi-transparent cedar stain left from this year’s application on my deck. What is the best way to store the remaining stain to maintain the maximum quality of the stain for the longest period of time between uses? Does it help to wrap the original 5-gallon can in plastic, after firmly sealing the original lid?

Most of my deck is pine in full sun most of the time. The wood has been installed for about 6 months. There is one walkway section that is fairly old wood but in the shade. I am considering solid versus semi-transparent for the new because I read solid lasts longer and also would probably match colors on both the new and old surfaces (not sure if that;’s true! And would it be an easier job if I used semi-transparent on the railings? What is your advice on the choices AC offers? Thank you!

I just reapplied a coat of semi-transparent cedar stain on my cedar deck. It looks good, but prepping it with the cleaner and brightener was very labor intensive because of a significant layer of moss-and mildew. After a few weeks, I’d like to treat my deck to prevent and reduce the amount of moss and mildew that accumulate over the winter here in the Pacific Northwest coastal town where I live. I have Wet & Forget. but have tead that it is better a killing existing moss, rather than actually prrventing. it. What is AC’s experience with this product, and are there others that you recommend for better prevention of moss and mildew?

Hi! We are building a covered patio in the PNW with a combination of DF glulams, DF #1 exposed rafters, and cedar t&g ceiling. All kiln dried.
We are looking to stain as soon as possible. Is it ok to stain as the members are being installed? Or do we need to wait for “drying”?
Also, trying to decide between the transparent natural or transparent cedar. Will the cedar yellow? We don’t want yellowing.
Thank you!

I’m staining an older deck (covered porch) here in Kitsap County in the PNW. I used a stripper followed by an all-in-one deck cleaner and brightener from behr. I also have done some sanding with 80 grit on the cedar boards after all that. I’m a bit worried about the weather and humidity. Does the air humidity matter? If there is rain in the forcast am I still ok should i wait for it to rain then a few days later stain?… =The transparent natural tone is pretty, is it ok for my deck here or should i be using a semi-transparent?

2 coats or one?
Can i use a lighter semi-transparent then like next year when adding another coat use a darker one?

I have a set of stairs with a small leading deck and railings that are 35 years old. I am looking to try to save them as long as I can and I can’t afford to replace them. They are still sturdy but I want to provide some protection so they last longer. In the past, I have used Thomson water seal but your wood stain was recommended as well as TWP 100 series. I’m trying to decide if either is worth applying and which would be the best and easiest to apply. TWP 100 only recommends wet on wet application but see yours can be wet on wet or wet on dry.
