Best Way to Apply TWP 100 and 1500 Series Wood Decking Stains

It is best to first measure the wood surface of your staining project. Do not forget to include steps, railings and spindles if you are staining a deck and double the footage of a fence if staining both sides. On average TWP covers approximately 150-300 sq. ft. per gallon. The newer the wood the less stain it will take. Older wood is more porous and will absorb more stain.

Prior to applying any TWP stain be sure the surface is free of dirt, grime, mildew or any old coatings. Use a wood cleaner when no old failed coatings are present. If an old coating is to be removed use a wood stain stripper instead. Allow the wood to dry for 48 hours after cleaning.

The best way to apply TWP is with a brush, roller, stain pad, pump or airless sprayer. Be sure to mix the stain well prior to opening. Use protective gloves and safety glasses and cover any plants, landscaping, concrete or windows you do not want to get stain on. Apply a light coat on one or two boards at a time or in a small section. It is best to work from one end of a board to the other then move on to the next board. This will help reduce overlap marks.

If one coat soaks in fairly quickly a second coat may be applied. A second “wet on wet” coat should be applied within 30 minutes of the first coat. Be cautions of over applying TWP Stain. If excess puddles of wet stain remain after a reasonable amount of time and or not being absorbed do not allow the stain to dry. Wipe away the excess with a clean stain rag or back brush the stain to blend it in. Leaving excess stain on the surface to dry will result in an unappealing shiny finish.

    I have a douglas fir front door that showed signs of weathering. I don't know what the original finish was. I sanded the surface, removed the dust and applied TWP cedar tone. Before appling TWP the door had a uniform appearance. When I applied TWP the surface has dark and light blotches. What would you recommend to correct the blotching? Thanks for your assistance. P.S. we used TWP on another property and It worked great!

      The blotchiness would have to due with the porosity of the Douglas fir wood grain and how the wood takes the stain. Ther is not a way to change how the wood takes the stain.

      No, TWP cannot be top coated.

      Try a graffiti remover from your local paint store.

    When staining the deck with air spray, do I stain the rail first?
    • We will reply to your comment shortly
      TWP Stains · 07/18/2020
      Does not matter but most will do rails first.

    Does this work well with air spray? Do I need to brush it after air spraying?
    • We will reply to your comment shortly

      You can spray the TWP with a pump sprayer or airless sprayer. You will need to back brush to ensure an even application.

    I applied series 120 last year and just didn’t realize I was supposed to add a cleaner before applying a new coat this year. The second coat makes the deck look wet, but it’s actually dry. I still have about a quarter of the deck to do. Should I just proceed with adding the second coat over my deck stain or should I clean the the whole Deck with Gemini and restart?

    Appreciate the help.

    Should I fill small cracks in my wood before applying TWP 200 or will TWP 200 fill those small cracks for me? Cracks are 1-3 mm
    • We will reply to your comment shortly
      TWP Stains · 07/11/2020
      No. Filler will not work on decks and will not blend with the stain. The stain also will not fill cracks. Just leave then as is.

    Can you apply a second coat after the first coat dries?
    • We will reply to your comment shortly
      TWP Stains · 05/31/2020
      Depends on how porous the wood is after the first coat. You do not want to over-apply it.

    It is Sunday. There is rain in the forecast on Tuesday and Wednesday. Can I clean and brighten my deck today or tomorrow (Monday) and then apply TWP later in the week, after the rain stops? Or do I have to apply the cleaner, brightener, and then stain with no rain in between between applications of the brightened and stain?
    • We will reply to your comment shortly
      TWP Stains · 05/31/2020
      Yes, you can prep now and stain after the rain.

    Hello,

    I finished applying TWP200 late last night around 9:00pm. This morning everything looks great, except they’re a few areas that I missed. Is it ok to try and apply over those specific areas?

      It is hard to spot apply and blend. It would probably be better to apply one very light coat to all wood.
      • We will reply to your comment shortly
        Evan · 05/14/2020
        Ok, but the first coat was applied 12 hrs ago, so this would not be a wet on wet application. Will there be any issue with the second coat absorbing into the wood?
        • We will reply to your comment shortly
          TWP Stains · 05/14/2020
          Possibly but the depends on how absorbent the wood is. It may take a few days to fully dry.

            Ok, I’ll apply a light coat over the entire deck thank you so much for the quick reply! Your product is great! Thanks

    We used several gallons of TWP 100 stain last year on our deck which had been built in 2018. We had prepped it with your cleaning system. We have a person scheduled to put the second coat on in May. There are a couple of small, black "streaky" areas on 2 of the top railing boards. Do we need to wash the deck before the second coat?

      You always have to prep when recoating. All the wood.

    We have a cedar deck and have found that renting an orbital sander is a better way to clean the deck than power washing or deck cleaners. They just leave the deck surface rough. It takes only 2 hours to sand a 700 sq ft deck. Then use a leaf blower to clean off the dust. It is ready for sealing right away without waiting for the deck to dry out. We use TWP-1500, cedar tone. We love the look and get many compliments on this 34 year old deck! Thank you TWP.

    I was told by a contractor that foam is the best roller material for applying TWP. Is this true? If not, what sort of roller should I use?

    Thanks

    Hello,
    I power washed my deck 12 hours ago (full of mold, etc.). Today I was planning on using the gemini clean/restore. Do you apply step two solution immediately after completing step 1? Also, how long before I can apply stain after step 1 and 2 are complete?
    • We will reply to your comment shortly
      TWP Stains · 08/02/2019
      Yes, apply Step 2 as soon as you are done with the Cleaner. BTW, you pressure wash off the Cleaner. Rinse the Brightener. Wait for 48 hours after prep to stain.

    Hello,


    I am looking to refresh our deck and we used TWP 1500 between 1-2 years ago, and want to apply a fresh new coat of stain, Do I have to strip the older TWP 1500 off, before applying a fresh new coat, or do I just need to apply a deck cleaner and power wash it clean, and then apply a fresh coat?


    Thank You

      You can not use polyurethane on a deck or over the TWP stains.

          TWP is typically 2 coats wet on wet unless new wood. Just one coat for new wood.

    What if you notice spots you missed hours after application? Can you go back and apply stain to spots you missed?

      You can but it will most likely not blend.
