Need Some Help With TWP Stains?

by TWP Help

Last Updated on January 30, 2023 by TWP Help

We are here to help you with your TWP exterior deck or wood restoration project for 2024!

TWP is an advanced wood preservative/protectant registered by the EPA. Performance and longevity can vary though depending on the wood type, how the wood is prepped, the age of wood, and how the TWP is applied. We want everyone who has decided to use TWP 100, 1500, or 200 Series to have the best possible results.

TWP Stain Tips and Help

When asking questions please give us some information about your wood restoration project:

  • What structure is your wood? Examples would be: Deck, Wood Siding, Fence, etc
  • What species is the wood? Examples: Treated Pine, Cedar, Redwood, Ipe, etc
  • Is the wood new or older than 1 year?
  • Has the wood been stained previously with a different brand? Please specify brand name and type of stain used: Examples: Solid stain, Semi-Transparent Stain, etc.
  • Any additional info that would be useful

Once you supply us with the information, we will able to give you advice as to how to prep your wood and any needed instructions for the TWP application.

Please ask your questions in the comment area.

Thanks

Forgot to say that I’m re-staining with TWP 120 Series Pecan stain.

It was cleaned yesterday so it’s still a bit damp in areas.

I just cleaned my cedar deck with a solution of water and TSP. I then rinsed it off with a power washer. It looks pretty good but there are some areas that have a white/grey haze on it. Would it be better to lightly sand the deck at this point or will a brightener remove the white/grey areas?

Do you recommend staining the underside of deck boards. I have KDAT decking and wondering if I need to stain/spray the underside after installation. I read that staining the underside may trap water/moisture that gets into the screw holes form the top (that would typically drain through the unstained bottom of the deck board). If the underside is stained then the moisture getting into the screw holes after it rains gets trapped in the deck board. Thoughts? My old deck KDAT boards had a lot of mildew on the bottom so I thought that staining the underside may protect from mildew? Should the rim joists be stained after installation? Also, can 200 Series stain be used on horizontal surfaces like deck boards – or only on vertical surfaces. Thank you.

Hi, I completely stripped my cedar deck and sanded it back in 2020, then applied 2 coats of TWP1500 (Color 1501 Cedar Tone). It stood up well for 3 years, but this year it has gotten to the point of needing to be restained. I used Defy Wood Cleaner on it, following all directions. I applied it, waited about 20 minutes keeping it damp the entire time, then used a scrub brush on the wood, followed by removing the cleaner with a pressure washer. I followed that, while still wet, with a Defy Wood Brightener for 5 minutes, then power washed that off several times to assure every bit of brightener was rinsed off. But, not all the stain came off (I did not expect it to since it is a cleaner and not a stripper). So, I have boards that have no stain, and others (mostly where the deck is always in the shade of the house), where there still is some to nearly all of the stain intact, but highly weathered. QUESTION: Can I now simply re-stain the entire deck and get a uniform color and correct protection with the same TWP1500 stain in the same color? Or, do I need to strip the deck to get a uniform coverage/color? It was a lot of work to clean and neutralize it, if I have to strip it, then I really just wasted my time and money on the cleaner, and it makes me wonder if the TWP1500 stain is really any better than any other stain since I can’t simply recoat it after only 3 years. I have attached a few photos to show what sections of the deck now look like. Please advise.

I don’t want to have to strip completely every time I have to restain. The question is: with the deck looking like it does now, if I apply a new coat of the TWP 1500 stain will it come out looking uniform or not? If not, then the TWP 1500 stain may not be what I want to use as it will always require stripping before it can be re-applied. Isn’t that correct?

OK, Thanks. One other quick question. If I use the RAD Stripper and mix up a gallon, will it “keep” OK in the sprayer for up to 8 hours to use a bit at a time during the day? That way I can avoid getting too far ahead of myself in trying to strip a section at a time. It is not always possible to strip when I have cool cloudy days, and I want to assure the stripper stays wet while it works. Then a second question: can I wait until I am completely done stripping to apply the brightener if I re-wet the already finished stripped areas, even if they have dried? I understand I need to completely rinse them very well before allowing them to dry.

I applied the 1500 stain, two days ago April 11, but I neglected to wipe off the access in time. There are sticky/tacky spots.
Are there any solutions to remove the sticky spots, any recommendations would be appreciated.

We have used TWP1515 Honeytone on our deck for several years along with the Restore a Deck kit but we still have dark areas and some places have little black spots, photos attached. We also tried the R-A-D stripper. Can you give us some advice, please.

I first stained my deck with TWP100 in 2017 and have been applying a maintenance coat every other year since then…so in 2019 and then 2021 and again in 2023.  Between maintenance coats, I have also applied the Gemini restorer and brightener. This year I had planned to strip the stain and reapply the same TWP 100 stain color, Pecan 120.

What stripper product should I use? Please see the attached photos of the deck.

I have an old deck that I’m considering using the TWP semi-solid on. After a couple years, does the stain fade away and allow for an easy clean and recoat, or does it begin to peel and have to be stripped and completely redone? Is the semi-transparent easier for maintenance? Thanks.

We have a a southern exposure 2 yr old pressure treated deck in Florida. This is the second stain on the deck. It was cleaned and brightened and then 2 coats of twp100 (wet on wet). It looks great, but seems quite dry like it needs another coat or possibly a sealer? Are sealers ever used over stains? If so, what do you recommend? Also, what can I do to slow down the mold and mildew? We are in a high humidity area. Thanks for your help! Karen

I’m a little confused on how to properly prepare a deck for application of TWP. Last year we power washed, used Gemini Restore-a-Deck and applied 1500 Clear—first time ever. The wood was mainly old, 2 x 6 CCA salt treated pine (50 yrs.—fortunately we live in the woods with a lot of shade), with some of the rotting boards replaced by newer salt treated pine over the past couple of years.
  I am assuming we should power wash again? Assuming yes: Safe Strip, ready-to-use in a power washer OR Gemini Restore-a-Deck combo package of wood and deck cleaner along with deck brightener OR Restore-a-Deck Stripper/Brightener kit? Overkill? Most cost effective?
Last year, 10 gal. of TWP just about covered all my deckboards. However, some of the decking is a dock over a fresh water lake, which the State Department of the Environment can get concerned and testy about chemicals over the water. Was thinking of adding the Bug Juice to the 1500, as we do have sections of the deck with carpenter ants.  Counsel? PS: nice product you make.

I stained my new deck last spring with TWP. It is now almost a year later and I am getting ready to stain it again! Do I only need to clean it since I am reapplying the same stain or do I need to clean and brighten over the stain from last year?

Hi there!

I purchased TWP 304UV Black Walnut from a bamboo retailer in San Diego California. They didn’t tell me that it doesn’t retain color. Do you have recommendations on a replacement that is a similar color that will retain the color? I know my options in CA are limited. Thanks!

I am looking to stain a deck that is right at a year old. It does not have dirt build up or mold on it yet. I think the twp 100 in cedar tone will work well for this project. Should I plan on applying 1 or 2 coats and will I need to still use the 2 step cleaning process first? Thank you

I can’t find my post from yesterday on this page, but you all replied and said “The blotchiness is part of the wood grain after prep. To fix, you would have to sand it all evenly with 60-80 grit and then recoat.” So, question on that answer… Should it have been prepped and then sanded or sanded, prepped and sanded again? Also, since we have to put the second coat on later in the year, should we sand before doing that, will that work, or will it mess up the 1st coat and make us start all over?

Thanks! So my contractor is just trying to figure out if they did it wrong? Should they have prepped then sanded? Or was it just bad luck that it turned out like that?

Is there a difference in TWP total wood preservative and TWP stain? I have used the TWP 120 Pecan preservative in the past on our cedar siding and was needing to order more but do not see the can/type I used before. Can someone help so I purchase the correct product? See attached picture of previously used product. Thanks

The pro series is semi-solid. I’m thinking what I used before what more clear so the wood grain shows.

We added a covered patio to our house 4 months ago. The ceiling is tongue and groove pine. We are looking to preserve the wood. Would TWP be a good fit? If so is one coat sufficient?  Since the ceiling is well protected from the elements, how long should we expect the application to last?

Can you mix driftwood with a 100 series or 1500 series dark brown (or similar in the semi-solid) to slightly reduce the gray tones in Driftwood semi-solid? How gray is the Driftwood in real life? I am trying to create a gray-brown Restoration Hardware type color.

We stained our cedar fence in Spring 2021 using TWP 1500 (1501), and want to apply the same stain again in a few weeks, once ambient temperatures cooperate. We think we know the correct prep, but can you please confirm? See attached pics…located in Northern NJ. Thank you…

In 2019 we stripped our 45 yr old pine log home to bare wood using your products. We restained using the 1501 series Cedartone. It turned out great and looked like a new home. It is time to restain. We plan to use the brightener prior to staining. Can we restain using a lighter color such as the 1500 series Honeytone. If we continue to use the cedartone the house will get darker, which we do not want.

Hi. We have a new deck, built July 2023 with pressure treated pine. It has not been stained or treated in any way, waiting for the wood to dry out. Is there a test to see if it’s okay to stain yet? Also, it has words/numbers stamped on it, I am assuming the 100 series cedar tone won’t hide those , so it be sanded to remove them?

Okay, thanks. So we didn’t know this, and obviously, didn’t sand it off right away. Should we not attempt to sand it now before staining or should we sand and then wait again?

I restain my Deck with TWP 1501 and really liked the look, but after we had heavy rains the color has changed, is this normal, and will it return to the original color after it dries. If not, what should I do to correct the problem.

Thanks,

Is the semi-solid stain more likely to show scratches, compared to TWP 200? The TWP 200 has held up well, but does show scratches in the high traffic areas.

Have Used TWP Stain on our San Antonio Tx deck 2 times. The Sun and severe heat was very hard on it this past summer .. Using past instructions from TWP we have hand sanded with a High power hand sander. Bought the Restore-A-Deck kit… Can we just use the Cleaner ? or would it be beneficial to do the Brightener as well.

If only one side of a cedar fence was stained w/ twp100 this summer will there be any issues or things to be aware of in the meantime or when the other side eventually gets stained probably early next summer? And will a previously opened and resealed 5gal pail of twp100 survive 10-12 months in storage?

Unfortunately I can only control when my side of the shared fence gets done, not the neighbor’s. So I’m basically asking these questions for him. You said there’s no way to prevent the bleed through and discoloration, so is there a way to limit it? And will a previously opened and resealed 5gal pail of twp100 survive 10-12 months in storage??

Craig

Not prevent, limit. Is there any way to limit (minimize, reduce, lessen, decrease) bleed through? Like don’t slop it on or being careful around edges and knots etc.?
