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.

    Can you apply a second coat after the first coat dries?

      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?

      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.

        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?

          TWP Stains · 05/14/2020
          Possibly but the depends on how absorbent the wood is. It may take a few days to fully dry.

    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

          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.

      Try a water-based graffiti remover from your local hardware store.

    How long does a new coat of stain need to dry? We purchased some stain and now I'm looking at the forecast to see what day would be best to apply it. Thanks!
    • We will reply to your comment shortly

      After applying, about 12-24 hours before rain.

    Can I use a graco airless paint sprayer to apply 1500 stain. If so, what size tip should I use? What pressure should I run the sprayer at?
    • We will reply to your comment shortly
      TWP Stains · 10/29/2017
      You can. Not sure on the pressure or that it matters. Tip should be a wide fan.

    Estella Draheim:
    We applied one coat of TWP 1500 to our deck. Is a second coat needed? And should it be done this year or next? And after that how often should it be done?

    Do a light second coat if needed in the Spring. Every 2-3 years after that.

    What is the best application tool to use for the stain. Would a wagner sprayer be suitable?

    You can use a Wagner but you will need to back brush to ensure an even application.

    Pam SF:
    Painter over applied TWP in some areas and it is shiny. It is day two now and still shiny and tacky. Can I still use mineral spirits to remove the excess?

    Yes. Saturate any oil rags in water and lay flat to dry outside.
