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.

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

  • 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

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

  1. Install wood and let site outside for 2-4 months or more.
  2. Once wood has been exposed, use the Restore A Deck Cleaner and Brightener Kit for prep.
  3. Let 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.

    Additionally, I am installing six 10-inch diameter columns on the porch, and if I don't pre-treat the flooring during installation, there will be no opportunity to treat the wood under the columns. Won't this be a problem having untreated flooring under the columns, with the opportunity for rot, etc., to occur in these areas?

      No. Wood stains like the AC are for exposed wood and would have no benefit for the unexposed wood. You want the wood to be able to breathe as well and not 100% sealed on all sides.

    I am replacing my Southern Indiana front porch (west facing) with new Douglas Fir tongue and groove flooring in November. Based on your responses to previous responses I'm assuming I need to wait until spring to apply any treatment (it won't be warm enough any time sooner). Is this correct? Additionally, I was planning on applying your penetrating semi-transparent stain to the underside of all the porch floor as well for added protection. However, once the floor is installed I will not have access to it. So is it better to apply a coat to the new wood before installation, or go without any application at all? Thx.

      No need to stain the underside prior to install. Wait until Spring, prep, and then stain.

    We would like to use stain on our front porch floor. House was built in 1900 & think floor is close to original. We did have to replaced a few boards & did so with kiln dried fir. Planning on having sanded to remove existing paint & stain next week. Do we need to wait until spring to stain? Local hardware store suggested to pour water on new boards to see if soaks in. Pic is example of one of the several spots I tested.

    I have a two newly installed IPE T&G porches under cover plus exposed IPE stair treads. The IPE was installed about 1 month ago. Waiting 2-4 months will put us into winter here in New York. I see responses below that is better to wait until Spring than to apply during the winter. Is this true to IPE as well? Will the IPE not weather and turn grey over the many months (8 or more) until the deck can be sealed in the Spring? Or will the Restore A Deck Cleaner and Brightener remove the greying of IPE before a Spring sealing? Thank you very much for your time and inpiut

      Yes, you should wait until Spring. It is okay if it grays, the prep kit will restore it.

    I have new KDAT Southern Pine. Is it better to stain the fresh boards prior to installation, or install the boards then stain? Also, do I need to use cleaner/brightener on the new KDAT boards prior to staining?

      Armstrong · 10/12/2017
      For this wood type, install first, let sit for 30 days and prep first with the Restore A Deck Kit. Only one coat of the Armstrong is to be applied.

    Hello.

    We finished our cedar deck floor-boards and cedar skirting in mid August. We live in Toronto, Canada and the temperature is starting to drop. Would it be best to apply stain now or wait until the Spring. If the answer is to wait should I apply anything for the winter or will it be okay for one winter season.

    I see a similar question recently posted but wanted to ask based on our different location. Thanks in advance.

    We recently installed a new cedar deck, finished approximately August, 2017. We live in Kansas and can have harsh winters, although not always. Should we stain our deck now or wait until spring?

    I have a new cedar deck that was installed 5 months ago. I will clean and brighten and allow to dry for two days. Then I'll also only apply one coat. How long should I leave the oil on before wiping? Secondly if the wait time before wiping is multiple hours, is it ok to walk on the oiled deck prior to wiping or will i leave footprints? Any tips for how to overcome this perceived issue would be appreciated.

      You do not back wipe the AC. Just apply the one coat and let it soak in and dry fully.

        Thank you. I'm concerned there will be tacky areas if I don't back wipe. Should I not be concerned about tacky-ness if I don't back wipe?

          You cannot back wipe the AC. If you do, it will not cure correctly.

    Jane:
    We live in Oregon and have new deck/porch railings plus a large pergola. They finished the work in mid-August. If we let the wood sit exposed for 2-4 months, it will be October or November when we can stain, which means lower temperatures and probably rain. Will that be a problem? Should we stain before temperatures drop and rain begins again?

    No. Best to wait until Spring.

    I live in Salt Lake City, Utah. Is there a dealer that I can buy AC from in my area? Also I just built my new deck out of redwood and cedar. How long should I wait until applying my first coat of sealer/stain?

    There are not any dealers there but we do ship there from this website. Takes about 3-4 days.

    Wait 2-4 months to weather and prep first.

    Ronda:
    Hello,
    We have just had roof built over our patio they used cedar posts and trim and the ceiling is tongue and groove pine. Do you recommend waiting to have the wood stained on vertical and ceilings? What is the best way to take care of the wood? We are in Austin Texas and just had a lot of rain due to hurricane harvey and I am wanting to make sure that the wood is taken care of properly so that it will last a long time.

    Yes, wait and lightly prep before staining as the article states. Redo as needed every 3-4 years for the verticals. Ceiling could go as long at 5-8 years.

    How about 30 yr wood?
    which of your products would work/last best and be easiest to apply.
    in my judgement the more oil in a semi transparent the better.
    also, what are your thought about applying linseed oil?

    Use the AC in a semi-solid for this older wood. Make sure to prep by removing any old coatings first.

    Hi there, I am reading the prep for the new deck, however, elsewhere cedar is being said to be stained as soon as possible.
    I used the sample on some cuts I have and the surface is very greasy, this tells me that would is not dry, any suggestions for cedar?
    thanks

    Cedar is not any different and needs to be weathered and prepped just as this article states.

    Richard K.:
    Can oil stain be applied to the underside of pressure-treated (southern white pine) decking without issues? I wanted to provide some protection to the underside of the boards, including the existing, aged joists, prior to installation, as the decking has a southern exposure, and is subjected to relatively damp, 4-season weather in Ohio. Thank you.

    Yes, but you will need to stain after install, weather, and prep.

    I live on Long Island in New York and had a new deck installed with pressure-treated lumber in March of this year. I would like to use your semi-transparent stain but I was advised to have the deck professionally sanded first if you could please confirm this is necessary? Thank you.

    You do not need to sand but use the prepping kit for the prep.

    I recently purchased Armstrong-Clark stain and Restore a Deck. The deck is 6 months old and ready for staining but, I am wanting to sand the deck before I stain. My question is would I use the Restore a Deck before sanding, wait for it to dry then sand the deck and then brush/compressed air to remove sanding particles and stain or sand the deck and then use the Restore a Deck wait for the deck to dry and then stain? I don't know how the water after sanding the deck will affect the overall outcome. We use the deck a-lot and I don't want to look at a finish disaster if I use the wrong process. Thanks for your help

    The best approach would be:
    1. Use the Step 1 and pressure wash the deck.
    2. Let dry and lightly sand.
    3. Apply Brightener and rinse well when done.
    4. Wait for 48hours to dry and stain.

    Water does not affect the outcome after any sanding.

    Maria St. John:
    Which product should I use for cedar porch only railings and thick posts? Is it the same you use for decks?
    I wish to keep the natural cedar color, but to protect the wood. I understand the less color the protection is lower.
    To order a sample is a great idea.
    Could you give me some advice?
    How much maintenance will be require? I live in TN, it is humid and the porch gets sun in the morning. Thank you so much!

    All vertical wood? You can use a transparent color on these. Clean and reapply every 2-3 years.
