How To Stain A Deck With Penofin Penetrating Oil

Whether it’s a barbeque with friends and family, a relaxing cup of coffee by yourself, or a glass of wine with your spouse, time spent on your deck is a little slice of paradise. To make sure it stays that way, however, you need to maintain it. If you have a wood deck, one way to ensure it lasts longer and stays beautiful is to use a high quality stain like Penofin.

How To Stain a Deck With Penofin Oil

Penofin stain was designed by a scientist with Ph.D.s in physics and nuclear physics because his friends dared him to make a product that was better than anything on the market.


To meet the challenge, the product “had to penetrate, seal, dry quickly, have minimum odor and bleed back, and be easy to apply. It also had to be stable enough to allow lacquers and varnishes to be sprayed over it if wanted.”

The rest is history and now Penofin (PENetrating Oil FINish) is well-regarded as a top-notch deck stain–one that we’re happy to distribute.

If you’ve stained before, staining with Penofin might be slightly different than with other stains. If you haven’t stained before, staining your deck is a rewarding project–but like any project, it goes more smoothly when you take your time and follow the directions!

How to Stain Your Deck with Penofin

  1. Make sure your deck needs staining. You can sprinkle some water on the deck and see if it absorbs immediately (you should stain your deck) or beads up on the deck and just sits there (your deck probably doesn’t need sealing just yet).
  2. Make sure you have everything you need:
    • Goggles
    • Broom
    • Deck cleaner
    • Hose (if pressure washing)
    • Brushes and rollers
    • Paint roller pans
    • Rags
    • Mask (if sanding)
    • Sandpaper / sanding tool (if sanding)
  3. Prepare yourself. Be patient and read the directions on every product you use. Check the weather and make sure you have several days of sunshine so your deck can dry out. Make sure it’s not going to be below 45 or above 80 degrees when you stain.

  4. Prepare the deck for staining. Clear everything off the deck. The manufacturer recommends that you use Penofin Pro Tech wood care products. The cleaner and brightener both come in powder form and are easily mixed with water. They take just minutes to apply and are environmentally safe. (If your deck is really in disrepair, you may need to sand it. Sand with the grain and wear a mask to avoid inhaling wood.)

  5. Stain the deck. Apply Penofin to a clean, dry surface, making sure the wood is not hot to the touch. Penofin can’t be applied over another stain, so make sure you’ve prepared the deck for staining.

  6. Brush on, use a stain pad, or spray on using a pump up sprayer equipped with plastic tip.

  7. After the stain has sat on the deck for 30 minutes, wipe off the extra stain with a cloth–don’t let the stain dry on top of the deck or it will get sticky and tacky.

  8. Wait at least 12 hours.

  9. Throw a party!

Not only does Penofin make your deck look great–and help it stay that way–the company strives to be socially responsible, promotes volunteerism, and strives for sustainability. Good values with great products are a win-win.

    What to do when a little too much product was applied and some areas are tacky?

    • Judy

      Penofin is a penetrating finish that penetrates into the surface of the wood. The surface of the wood must be wiped thoroughly with nap free cloths to assure that no Penofin dries on the surface of the wood. If you allow Penofin to dry on the surface of the wood it will turn sticky and tacky and eventually peel off the surface because it is not a surface coating. It will also interfere with the cure of the product that has penetrated into the wood causing the product to fail to protect the wood fibers. If you already applied Penofin Stain and it is now tacky, Penofin Pro-Tech Cleaner applied according to directions will clean the finish, once dry. If the wood appears blotchy apply a light coat of Penofin according to the directions on the can remembering to wipe.

    My contractor want to put 2 coats of Penofin on our new cedar deck. Will that be ok?

    • Judy

      Great question! We spoke with Penofin regarding your cedar deck. What matters is whether or not the cedar wood will absorb a second coat. Apply the first coat and wait about 30 minutes after the wiping stage. Apply a second coat in a small test area to see if it will absorb a second coat of Penofin Stain. If it is not absorbing more stain, it would just be wasted in the second application during the wiping stage. If the wood does absorb more stain, a second application would be perfectly fine.

    I just Stained My New Cedar Deck with Penofin Red Label Clear, if you want to see how it applies or how it looks give my video a look

      Ive read online from other reviews that cedar blackened after using this product. What was your experience?

      • Judy

        Thank you for your question. It’s a good question because blackening on wood can happen, regardless of the product you are applying to your exterior wood project. There are three primary causes for wood blackening:

        • Excess Oil is Applied The solution is simply to not over-apply the oil. Be sure to read and follow the installation intructions.
        • Mold and Mildew If the wood was already penetrated with mold spores, it will continue to spread. If mold is in the wood, it’s not the stain that is blackening. It’s actually mold spores within the wood. If this does occur, the solution is to apply Penofin Cleaner.
        • Extractive Bleading Tannins naturally exist in all wood species. Some species have higher levels of tannins than others. (Cedar, Redwood and Hardwoods have particularly high concentrations of tannins).

    I used Penofin stripper, cleaner, brightener and stain and some of the wood surface feels kind of like fir. What did I do wrong?

      To clarify, does it feel fuzzy? Did you power wash it before cleaning?
