    Pine deck in great condition.  Previous owner applied orange latex solid stain.  I’ve stripped it to about 99 percent bare wood.  Getting the other 1 percent off has taken me almost a full day of labor but most of it is still there.  Two questions: 1. will applying 1500 over deck be possible.  2.  Will the orange latex stain that remains stand out.

      1. After full removal, you need to use this kit for final prep to open up the wood grain:

      2. It has to come off 100%.

        It is an impossibility to get it all off.  The only remaining is inside of checks in the boards.  So the implication is that if I can not remove that minuscule amount TWP is not a product I should be using?

          You cannot use a semi-transparent stain over a solid stain as it can have issues with adhering and or the solid stain showing through. This is not related to TWP but any stain with a lower opacity.

          If you can deal with it showing through on the inside of the boards a little, then you should be okay as far as performance.

            Yes that was the question.  The solid stain is still in cracks and other hard to reach places.  This is what it looks like.

                Thanks for all thehelp.  Final question, I know1500 is a penetrating product. In thefew placeswheretheoldcoating remains, willit (dark oak) color theoldsolid stain or willtheoldstain showthrough as it’scurrent color. Tryingto decidebetween sticking with oak or changing to cedar tone so theoldcoating willstick outless

                  It will show through the TWP so best to use a color that will blend it.

    When prepping for 1500 Black Walnut over douglas fir, it is advisable to apply a wood conditioner such as Daly's Benite, prior to staining?  I've had blotching issues in the past with doug fir floors using interior clear oil finishes that were remedied with conditioner.  Thanks.

      No, do not use a conditioner with TWP.

    In prepping for 1500 stain, I used a paint remover for some difficult areas on my garage door.  When I applied the brightener, I noticed some areas still had paint remover residue present.  I used denatured alcohol to fully remove it because it evaporates.  There doesn't appear to be any difference between the areas where I applied the brightener and those with the denatured alcohol.  Should I reapply the brightener over the areas where I used the alcohol?  Thanks.

    Teak wood is 4 year old flooring for covered front porch. Not previously stained but has turned a greyish color. We would like to restore the rich color of teakwood if possible. Do you think your product can achieve our goal?

    Is TWP 1500 available in slate grey? 100 series is not compliant in Pa, and client will probably want slate grey.

    We have an old seasonal cabin. It was last stained with Cabot’s Australian Timber Oil, approximately 8 years ago. The siding is dry and thirsty for stain and thus we hope to switch to TWP. It’s not accessible to easily strip. Can we clean the siding and apply the TWP semi solid 1500 product?

      No, you have to strip and brighten whenever you switch stain brands.

    I'm refurbishing a 28 year old log cabin.  I striped the old finish off the logs and have sanded them with 80 grit sandpaper.  Now I'm getting ready to apply new stain.  In the time it took to strip all the logs, some of them have begun to turn gray again.  What should I use to brighten them and prepare them for restaining?  Also, I'm thinking of using the 1500 series stain.  Any recommendations?

    Can you apply TWP 1500 directly over Woodwright 3000?

      No, you would have to remove that first.

    9 year old pressure treated stairway in upstate NY.  Applied one coat of of 1500 yesterday & handrails are dry and look like they could use another coat.  Can another coat be applied?

      Second coats need to be wet on wet so best to leave them alone for now. You can always lightly clean and apply another coat to them next year.

    Installed appropriately 3months ago.  Premium  pine (not 100% sure). Brand new wood. Thinking about the 1500 series. It's allowed in NY.  I'm in west Babylon, long Island.

    Most of the deck wood absorbed The stain like you described but a few small areas look as if the 1500 stain is still wet. The stain has been on the deck for 20 hr. Will it dry ?

    I live at 6500' in Colorado, and my new deck gets over 8 hours fulls sun each day. I'm thinking of doing the TWP1500 this fall, though that product is semi-transparent. Should I use something more solid? If so, which product? Thanks

      No, you would want the TWP 1500 Series.

    I have a 15 year old cedar deck that I had all the horizontal surfaces sanded (630ft2) and one coat of TWP 101 Cedartone applied 6/23. Previously deck stained with Benjamin Moore Arborcoat solid deck stain 2 years ago and severe pealing from all horizontal surfaces. After several rainy days it appears that the TWP has wash away and want to apply another coat using 1500 product. Any special prep that you would recommend before applying? Can I just power wash, allow to dry and apply new stain? 

    As a side note, the former company I hired to sand and seal the deck just blew off the sawdust after sanding and applied the first coat of TWP100. No special prep was done before the first coat.

      If you sand, you should never sand finer than 80 grit. If sanded, you should clean and brighten after to open the wood pores with this kit: https://www.twpstain.com/gemini-s-restore-a-deck-cleaner-and-brightener-kit

      When wood is sanded, you can only apply 1 coat of TWP. All that being said, you cannot just add another coat to your sanded deck at this point, and not of a different series. Best to leave it as is until next Spring. It will be fine. When time, do a full prep and recoat then.

    Large 16' wide 10' high cedar doors, 80+ years old. The wood is sound and beautiful. Was previously finished with Sikkens proluxe which is now peeling off. It faces SSE, exposed to full sun until 2-3pm, NY area. Also gets some rain splash which causes blackening of the lower foot or so. Would TWP 1500 with a recoat schedule work better than a varnish? Thinking about how long it would look good and how much work goes into the maintenance refinish.

      TWP Stains · 07/21/2023
      Varnish will peel on a deck. You have to fully remove the Sikkens before using the TWP or any other penetrating stain brand. You clean and recoat with the TWP in the future.

    Also have a large deck with rail of pressure treated wood in upstate NY the receives 50% direct sun.
    It is 7 years old and the exposed parts are just starting to show signs of graying, with some mildew on rails only. 
    Which product would allow the longest protection going forward, and what prep materials would be needed?
    I asked before that the "rustic" color seemed a good choice, but is it too red?
    Thanks for the help to determine my needs, Tim
