TWP 100 Series Deck Stain Review

TWP 100 Wood Deck Stain

TWP 100 Series Stain RatingImportant Note:  This is our 2nd Review of TWP 100 Series.

See our other reviews of the TWP 100 Series here: TWP 100 Wood Stain Reviews

TWP 100 Total Wood Preservative Deck Stain protects and maintains all exterior wooden surfaces. TWP Wood Stain is a special blend of chemicals in a contractor grade formula that safeguards and protects exterior wooden surfaces.

TWP 100 Wood Deck Sealers lock out water and moisture that causes wood to crack, split, and warp. Freeze damage is also prevented in cold climates.

TWP Stains are the only wood and deck stains on the market that are registered as exterior wood preservatives by the EPA.

TWP Stains – 100 Stain Review

TWP 100 Series Wood Deck Stain Scores (1-10)

Appearance After Initial Stain Application: 9

– The TWP 100 Stain was applied to a very large deck surrounding a pool. The wood was about 1 year old at the time and was prepped with the Restore-A-Deck Cleaner and Brightener kit. The wood was a knotty cedar and the Cedartone 101 color gave a rich look that is typical of a cedar stain. Knots and grain where enhanced and the stain dried evenly for the 2 coats that were applied to the floor.

Preventing UV Graying at 2 Year Mark: 8

– Same as the first time tested, The TWP Cedartone 101 retained about 80% of the original color after 2 years of weathering.

Wear/Tear and Peeling: 8

– We found that the TWP did wear slightly in about 20% of the floor area. It was mostly in the high traffic areas that surrounded the pool. The upper level deck in the back had little to no wearing.

TWP 101 Cedartone Color

TWP 101 Cedartone Color

Cost Per Square Foot: 8.5

– The price paid was $159.99 for the 5 gallon pail of TWP 101 Stain. We used all 15 gallons for the 2100 foot pool deck. We applied two coats to the floor and 1 coat to the railing.  Cost to stain with TWP 100 Series was $.23 per foot.

Preventing Mold/Mildew/Algae: 10

– No mold, mildew or algae spores were present.

Ease of Application: 8

– As you can see from the photo, this deck was surrounded by a pool. We needed to be extremely careful of getting any stain into the pool. We did all flooring with a stain pad that allowed the stain to apply evenly and absorb well. We tarped the railings to prevent over spray and used a pump sprayer to apply to the spindles, back wiping the drips.

Color Shifting (darkening) after 2 Years: 9

– The TWP did not darken from mold or UV discoloration. Slight water spots were noticeable around the edge of the pool.

Difficulty of Reapplication: 9

– Reapplication will be easy without the need for stripping off the two year old stain. The use of a wood cleaner and wood brightener should be sufficient prep. On this particular deck, we cleaned and prepped the flooring and reapplied to the floor and top of the railings. We did not do the verticals as they still looked good form the original application.

Overall Score TWP 100 Series Stain at 2 Year Period: 8.69

– As contractors, we enjoy using the TWP Stains. It penetrates well into the wood, fades lightly in color and holds up to wear and tear. We like that when it is time to redo the wood in 2-3 years, the TWP can be cleaned and re-coated or even removed with ease. This makes the reapplication process much easier.

Note: We do not use TWP on brand new wood. If applied to wood that is less then 4 months old, it seems to have a difficult time with penetration. We find this with many of the stains we have used on new wood. The manufacturer suggests waiting 4-12 months to let the wood weather. We strongly suggest that you wait.

    loved using this product! What an improvement over the Behr and Wohlman's!

  2. Ralph says:

    Excellent site, thank you! We began building a screen porch in May this year with new cedar (western red). We're in Minnesota and the decking was beginning to gray just slightly. (southern exposure) On the recommendation of our local Home Depot I applied Behr's Transparent Weather Proofing – All In One Finish in cedar natural tone just to the decking/floor boards. It's water based and is after 4 weeks still sticky when you walk on it and is more like paint than stain. I'm very disappointed and wish I had found your site before applying their product. I should have gone with an oil based product that would actually penetrate the wood. The rest of the porch – posts eve's etc. are also cedar and the goal was to stain it before it turned too gray. My questions are –

    1. What should I use to remove the water based product? From reading it sounds like sanding could make future staining less optimal for penetration. Not to mention 12 X 16 deck is a lot of sanding.

    2. Should we wait through the winter before applying anything as you indicate new wood doesn't stain well and if we wait will the cedar gray too much during this time? Our preference is to preserve the newer color with a semitransparent stain.

    3. Do you have a recommendation for sealing the cathedral ceiling, rafters and support beams which are made of Douglas Fir?

    I would happily pay for advise or further consultation, thank you!

    • Strip off what you can but you may need to sand as well to remove all of the Behr as it can be stubborn. Use a wood brightener after the removal. You can wait until spring to do all this. You can use the same stain on the ceiling, rafters etc.

  3. Michael says:

    I live in Kansas and am re-staining a cedar pergola. We have already cleaned and power washed. We are considering the TWP 101. My question relates to application. Due to the proximity of the pergola to the house, we will have to apply with a brush/roller. I see the review indicates "wet on wet" application…will you explain what that means? We also have a newly installed rough sawn cedar fence. Do we need to let it weather before application of the TWP 101?

    • Apply the first coat then apply the second coat within 20-60 minutes of the first coat. Rough sawn cedar fence can be stained without the weathering when new. It is much more absorbent.

  4. julie says:

    Where can I purchase the stain in Western Colorado.

  5. Nancy says:

    We just finished sanding Our 700+sq. foot deck because of the stain we used two years ago gave us terrible results. The wood we used was Deck Wood. We're trying to decide what stain to use now. We don't want to go through this again. TWP 100 sounds like the answer to our prayers. Since we just sanded the deck down to the bare wood, is there a time we should wait to apply the TWP 100 or is there is something else we should do to the deck before we apply the stain?

    • Prep with a deck cleaner and wood brightener to open the grain so the stain absorbs deeper. That will help. Do not over apply the TWP. You want it to penetrate fully into the wood grain.

  6. George Grauvickel says:

    Can I apply this over existing stain?

  7. jeff says:

    I live in northeast Iowa with a west facing deck. What is the best semi-transparent stain that will last and help fight off the elements of sun, rain and snow? The deck is about 15 years old and is pine I believe and is in very good condition.

  8. Sue Crowley says:

    Hi, we live in Maine and had a pressure treated pine deck built around an apple tree(beautiful but messy). We are ready to stain our deck and bought a cleaner but havn't tried yet. We want to keep it as close to its natural color as possible and see the wood grain. What do you suggest for a stain? It's about a year old. Thanks. Sue

  9. henry lance says:

    Can TWP be used over 3 yr old deck that has had two treatments of Messmers clear oil stain on it all ready,

  10. beckyg says:

    Can't say how TWP 100 Stain will look at the two year mark but having lived with 1100 sq feet of wood deck for 20+ years I can say that I have never used a product that went on as easily than this one. No problems with lap marks and able to go back and get thin spots. Having used major store brands and the heavy advertisers where the stain turns out to be paint and the waterproofing doesn't make through the second storm I'm ready for a real, live, stain that actually soaks in. If this even starts to last I'll be quite happy

  11. Mary says:

    I live in Missouri and just power washed my deck that nothing had been done to for at least 5 years. After much research, I want to use the TWP product. But I have a couple questions.
    1. Do I really need to use a cleaner or brightener, or sand before using the TWP 100 Wood and Deck Stain?
    2. Do I need to use a Deck Sealer on top of the first product?
    Thank you for this useful site.

  12. Jules says:

    Hi. I'm in Pa and have a very large 1 year old pressure treated pine deck which hasn't been stained. I didn't replace my steps which have some old stain on them. I purchased the Gemini cleaner and brightener and plan on using twp stain. Daytime temps will be dropping to mid 70's, but, evening low temps will be mid to high 40's. Please answer the following for me : what stripper Do you recommend on the steps? How long do I have to wait between stripping then cleaning and brightening? In fear of incorrect application and failed stain, I am wondering if a single coat would be sufficient to protect from harsh winter and full sun? Will low evening temps slow stain dry time and/or contribute to stain failure? Best tool for floor application? Lastly, 100? Or 1500? Thank you in advance.

    • 1500 for PA. What stain brand and type is on the steps? Makes a difference as the stripper needed. Do all the prep the same day but strip first. One coat this Fall and then maybe a light coat in the Spring after a light wash to remove dirt. Use deck stain pads for applying.

      • Jules says:

        I'm not sure what brand of stain is left behind, but, it is solid color–most of which was washed off with a pressure washer last season. Since I am running out of "good weather" days here, will the drop in eve temps below the 45 degres minimum application temp Cause stain failure? Also, is a brightener required for staining success? If yes, can the brightener be rinsed with a hose only? Thank you for your time!

        • Deck Stain Help says:

          Jules, you will need to sand off the rest of the solid stain then both clean and brighten all the wood for the prep. Dropping below 45 at night does not affect the stain. Brightener can be rinsed but cleaners need to be pressure washed or heavily scrubbed.

  13. Larry says:

    Good morning, I live in Downeast Maine along the coast and we are getting new Western Cedar STK decks installed over the next few weeks. You recommend that the wood should season for up to a year before staining. That would mean our new decking will need to go through a full winter (lots of snow and very cold temps). Should we consider sealing the decks now and look to applying a stain next summer, or should we be okay with letting the deck just sit and then clean/stain after this winter concludes?

  14. Jan says:

    Not only do I have a large deck but also have log siding that's is in desperate need of restaining. I live in NE so we see it all. Am considering the TPW100. We are in the process of powering washing off old stain, graying, dirt, moss etc. Questions: 1) what additional measures should be used to prep all surfaces? 2) will TPW100 work on log siding as well? 3) I have noticed some log homes have a glossy sheen to their logs. Is there an additional product that is applied after staining to produce this result or a different stain entirely?

    • 1. Just make it is clean, free of mold, and no old coatings.
      2. Yes it works great on vertical logs.
      3. You cannot apply TWP over a old stain with a sheen not can you apply a product on top of the TWP that would create a sheen.

  15. Lee wheeler says:

    I live in northern Wisconsin. I have a one-year old pressure treated cedar deck and sidewalk that haven't been finished yet, as I was told to wait a year. I've read many of the comments here and am still confused as to whether the 100 or 1500 series would be better here. Not sure what the difference is. They get full sun until late afternoon and are high traffic areas as the deck is the way into the house and the sidewalk connects the garage to the house. Also, it's now getting down into the 30s at night with highs in the 50s and 60s in the days. Is it too cold to stain at this point? Hoping for some warmer weather yet, but not sure…

    • We would use the 100 Series after prepping with their Gemini Restore Kit. As for the temps, we stain in these temps during the day but will not apply stain if the temps below freezing at night.

  16. Roberta says:

    I had a paint contractor stain my very large deck. He used Cabot solid stain. It peeled the very next year. I have just finished stripping my deck down to the bare wood and used all of the cleaners and brightners. I am having a very difficult time deciding which stain to use, so I don't have to strip it all of the time before I reapply. I do not want a solid this time. I want something that will soak in and protect the wood. I have a western facing deck that only gets shade in the morning and I live in northern Indiana. I have done much research and am sfill having a problem deciding which product to use. I have heard that Sikkens was good and so was Defy. Any suggestions will be much appreciated.

  17. Larry says:

    I need to re-stain my PT Pine deck. I have been able to pressure wash off most of the old stain but some remains. From the readings of other comments, I percieve that oil based is out since I cannot get a completely new surface for it to adhere to. Am I right? I need a dark brown solid stain. I'll be using it to cover the deck, dock, stairs to the dock, and various trim. What would you recommend?

  18. Judy Mulheirn says:

    I live in Dallas TX and have a 20 year old TP pine deck that is very large. It has been power washed and I would like to stain and seal it. There is some feathering. I assume I need to sand it first before applying any product. Which Product is best for this aged deck? And what would be the best application method?

  19. Michele says:

    We just had a new cedar porch built on the back of our lakefront home (upstairs and down) with 10" posts and 2" railings that faces east (direct sun every morning). I love the look of the new cedar and want to do everything I can to prevent it from graying out. We're located in west TN where the weather has a tendency to go to either extreme. Our contractor has suggested Behr or Olympic to seal it now (even if just a clear sealant) but I want to do whats going to be best in the long run vs. short term fix. I like the reviews of TWP, but it says to wait 4 months which puts us in middle of winter months. Any suggestions?

  20. yoann says:

    I live in San Diego, CA

    I am having a deck build in few month from Ipe or Redwood. I am trying to opbtain a redish color.
    I was reading online the product "Ready Seal", do you recomend TWP, if so which one?
    Thank you evry much

  21. Mike says:

    Live in Denver area. 3 years ago, the last owner put on his yearly application of a very gooey type of oil based wood stain on what I believe is a Redwood deck. He would apply every year and although the deck was 20 years old when I bought it, it looked brand new. It is a West facing deck. Half of it only gets sun in the winter and the other half get a fair amount of sun in the summer and of course more in the winter. My house gets 20% more snowfall and 20% more wind than an average suburban Denver area house (I have measured this). I made a mistake a lightly pressure washed the deck a year ago while preparing to put on Behr DeckOver so I could have a 5 year life instead of a 1 yr life. I blew it and didn't do the staining and found myself having to go through an entire winter last year and all summer this year and it still hasn't been done. I am now wavering on doing DeckOver because the prep time will be too long (I caused this myself obviously). I am in the position of needing to sand the deck because of my laziness and I don't have enough time now before winter sets in. The temperature is barely within range to apply a stain. Realizing that I must do a complete job of things next spring, what should I apply that will be easy to apply and yet easily removable next spring when I do a complete reconditioning job with a large sander and all of the other prep that a pro would use?


    • Mike, you should not apply anything over the layers of the old stain. Leave alone and strip it all off next year.

      • Mike says:

        Thank you for responding. Normally I would agree with you but let me add this clarification. The old stain has almost all withered away. It has gone far enough on the deck floor that in my opinion, oiling the deck would totally soak it and not just gum up the surface. There is maybe only 10% of the old substance on the surface anymore, if that. The railing is much better of course. Fortunately, the 4×4 posts are in concrete and you can't even budge them. The 2×8 cross supports are totally OK too. However, the deck is extremely dry and starting to crack everywhere, although the railing is easily restorable. I am very afraid the deck will get a lot worse over the winter. I was thinking that if I applied some sort of a linseed oil to add a moisture barrier and also relax the drying wood, that oil would soak in deep enough to partially remain even after I refinish it next spring. I am also rethinking applying the DeckOver product. Let me make an educated guess that DeckOver would work much better if the subsurface wasn't already so dried out. My guess is that even with the most perfect prep work in the world next spring on an overly dried out subsurface, will allow the deck to continue to deteriorate from beneath and between the 2×6 decking boards. A product like DeckOver or any other product that is only a cover up (doesn't penetrate very deeply nor does it moisturize the wood), only prolongs the inevitable, it doesn't restore anything. My question is: Would a different product be better able to actually restore the wood as follows: Sand with large ____ type sander, fill larger cracks with ___ restoration application (not for the entire deck surface, mostly just the cracks that remain after sanding), remove and replace screws that are loose (applying a ___ brand sealer or glue in the few screw holes that became over-sized) and then applying 2 coats of the final deck product. If you are in agreement with the above for the most part, what would be better in this case than DeckOver, so I wouldn't have to keep applying a new application every one or two years?

        Also, if I could completely cover the deck with 6 mil industrial grade plastic and seal all of the edges so no moisture could get in, would this be a better option than letting the deck dry out even more? My fear in the Denver climate is that we have have a very regular "freeze / thaw" cycle nightly because our temperatures vary so much. The good part is that we don't get moisture as regularly as some climates but at the same time, the temp will go below freezing and then rebound the next day with bright sunlight. THe UV rays dramatically speed up the drying cycle in the morning which then leads to a more dramatic expansion and contraction.

  22. Susan says:

    Live in north central Florida. We have a 13 year old never stained, pressure treated pine porches (approx 1000'). Would the Restore-a-Deck kit and then TWP 100 semi transparent stain be a decent choice for our area and wood type?

  23. Kim says:

    I live in South Florida and have an 8-year-old pressure treated deck that I just cleaned and need to stain. Is there a product that is good for areas with lots of rain and humidity. I need something that dries fast because we rarely get a 0 percent chance of rain forecast.

  24. Travis says:

    I live on the Lake of the Ozarks in mid Missouri. We have over 2,200 square feet of Decking to stain this spring. I NEED the best! Id like to do this in one pass and be able to re-aply without any headaches later on. Please let me know your suggestions on getting my deck ready for stain and your suggestions on stain and keeping it nice. Thank you.

    • Deck Stain Help says:

      The TWP 100 would be a good choice. It can be cleaned and reapplied as needed without hassles. Prep first with the Restore A Deck products.

  25. Barbara says:

    I had a new deck built with pressure treated wood what would be the best product ?

  26. Cynthia says:

    Hi. I have a home with cedar siding on the coast of Maine. It has only been stained and sealed once, when it was built 9 years ago. Used Messmer's UV Plus. Thinking of switching to TWP with just cleaning and pressure washing. Will it take or would it have to be stripped? And, if so, would you recommend simply staying with Messmer's? Please advise as I have no idea. Thanks!

    • Best to remove the Messmers. Strip and brighten for the prep. It will be easy to do as Messmers comes off with no issues. For Maine, you will need the TWP 1500 Series as the 100 is not allowed there. We would suggest this.
