Important Note:  This is Our 1st Review of TWP 100 Series Stain. Our second review was completed in 2012. Please see here: TWP 100 Stain Review 2013

TWP 100 Series Wood and Deck Preservative has been manufactured for over 20 years while proving to be one of the best products on the market.  TWP Stains are registered as wood preservatives by the Environmental Protection Agency, the only stain to achieve this distinction. TWP 100 Series is a 550 VOC compliant wood stain that is available currently in 36 states. Composed of natural and synthetic oils, TWP 100 Series will provide ample protection from snow, rain, and ultra violet radiation.

TWP 100 Series has been rated #1 by Consumer magazine.

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

Appearance After Initial Stain Application: 8.5

- We tested the 101 Cedartone color for the pool deck. The semi-transparent color was a traditional cedar color, slightly orange/yellow. The stain had no issues penetrating into the wood completely and did not mask the wood grain.

Preventing UV Graying at 2 Year Mark: 8

- The TWP 100 Stain retained 80% of the original color after 2 years of weathering.

Wear/Tear and Peeling: 8.5

- TWP 100 exhibited zero peeling of the stain after 2 years. Slight wearing around the stairs where the wood butted up to the pool. This area was slightly more faded as well. Possibly from the chlorine in the pool.

TWP 100 Series

Cost Per Square Foot: 9

- We paid $139.99 for the 5 gallon pail of TWP 101 Stain. We used all 5 gallons for the 800 foot pool deck. We applied two coats to the wood. Cost to stain with TWP 100 Series was $.18 per foot for 2 coats of stain.

Preventing Mold/Mildew/Algae: 10

- TWP offers the best resistance to mold and mildew for an oil-based wood preservative. No mold, mildew or algae spores were present on the wood decking.

Ease of Application: 8.5

- TWP is easily applied. We applied two coats to the flooring using a 18″ wide stain applicator. The first coat took us about 30 minutes to cover 800 feet. Second coat took only 20 minutes as the TWP 100 applied at a better spread rate. Overall the 800 square feet was covered in under an hour and applied evenly with no puddling.

Color Shifting (darkening) after 2 Years: 9

- TWP 100 lightens in color after 2 years. No darkening from UV or mold.

Difficulty of Reapplication: 9

- TWP 100 Series offers deep penetration with no darkening of the stain. Reapplication will be easy without the need for stripping off the two year old stain. Cleaning to remove some dirt and grime would be enough to prep for another coat.

Overall Score TWP 100 Series at 2 Year Period: 8.81

- TWP for good reason gets one of our top overall scores. It is too bad that this product is not available in all 50 states but the TWP 1500 Series performed nearly the same in our test results and can be obtained in all states. If you are looking for a great stain that is economical as well, then the TWP 100 Series should be considered.

    Live in Pa, Have a deck that is 3 yrs. old, never been stained or weather proofed. Where should I start and what to use?

  2. Clyde says:

    OKC area 1200 sqft deck of which 900 is new smooth pt pine & remaining 300 is 15 yr old previously solid stain pt pine.
    Allowing new decking to weather possibly until spring and will clean/brighten all areas prior to stain application.
    Wanting to use TWP stain products which is based on all available product reviews. Which TWP product will best suit my situation?

  3. Clyde says:

    Very little solid stain remains hopefully will remove residue with cleaner/brightner application and pressure wash. Any thoughts? Also why TWP 100 over TWP 1500 product?

    • Clyde, cleaners do not remove solid stains. Stripper may a little but they also in general do not remove solid stains. You cannot cover a solid with TWP so get all of it off if you can. 100 is better at penetrating.

    We live in Illinois and have a cedar deck that is about 12 years old. We previously used Sikkens on it and have never been happy with how it holds up (peeling & fading) causing us to have to redo every few years. My husband used a cleaner on it and pressure washed but there are some areas on floor where Sikkens did not come off and the railings still have Sikkens on them. What would we have to do to remove the rest of the Sikkens from the floor and railings before applying the TWP product? Thanks for your help!

    • You would need a deck stain stripper and pressure washing to remove. You may need to do this a few times as Sikkens can be difficult to get off. Apply wood brightener when done.

    Hi there,
    We just installed a new Western Cedar deck and were wondering what prep. is required prior to staining and what type of stain you could recommend out of the ones we have available here in Edmonton, Alberta (Canada). We get cold winters with lots of snow and warm summers with low humidity. The deck is east facing so it gets a lot of sun during the day but is in full shade in the evenings.
    I hear TWP and Armstrong are really good brands for deck stains, unfortunately neither is available here. I have seen the following sold here: Wood Pride by Dulux, Behr, Sikkens, Cabot, Benajmin Moore, C-I-L, and Olympic.
    We would prefer a stain that allows more of the wood grain to show through to one that also doesn't require too much maintenance (if possible).
    Thanks for any help you can give us.

    Hi!
    I purchased a 12 year old home 4 years ago (western NC) with a 2nd story back covered deck (8X40). This year, the center part of the deck still looked nice but the parts which received the most sun had very little color and the water didn't bead up. I used SW Deckscape stripper & revive products then a final power washing because I wasn't sure what was previously used on the deck (wood grain showing but a 'honey' color – the wood is probably pressure treated pine from Lowes). I am a DIY newbe. There are places where the wood looks 'furry' – maybe too much pressure washing / scrubbing with the nylon brush? I noticed you don't recommend sanding but should I sand under these circumstances? If I do have to sand, would it be enough to use a leaf blower to remove dust?

    I am 60 so In the future I would like to complete regular maintenance that would let me treat one half of the deck and then the other half of the deck so I wouldn't have to move everything into the yard for a week or more and I wouldn't have to cover everything below deck and in the yard because of harsh chemicals. Can you recommend a semi-transparent stain and a proper maintenance schedule?

    Thank you for your help!

    • You can sand with 60 grit to remove the furring. Use a light pressure washing after to rinse off the dust and open grain of the wood for better stain penetration. Use the TWP 100 Series and maintain every 2-3 years or as needed.

    We live in Lawton, OK, temperatures can get extreme here but we applied TWP 100 Cedartone to our 20×20 deck in the middle of April. temperatures from then until July have been well below normal. The deck was 18 months old at the time and was pressure treated, according manufactures specs this was a seasoned deck, nonetheless we sanded the entire surface, was smooth and clean before application of two "wet" coats. drying time was very fast, next day patio was ready for furniture. It came out beautiful, very nice shine to it, deep color, absolutely outstanding. for about 3 weeks.After that the shine is complete gone, very dull looking. We are extremely disappointed with this product, after looking online there is no warranty associated with the stain. In my opinion this stain is a complete failure, to have less than a month of newness is ridiculous, would NOT recommend using this stain at all.

    • Dean, TWP is not supposed to be shiny at all. It is a penetrating oil based stain that is supposed to a flat appearance. No high quality decking stain will be shiny as that will create a huge peeling mess. Your expectation for the TWP and stains itself are incorrect for being shiny.

  8. Amelie says:

    I have a 20 year old mahogany deck that we have sanded clean and beautiful. I want to apply a clear sealer that will haelp to maintain the natural color of the wood and can be reapplied WITHOUT stripping. What would you recommend?

  9. Alan says:

    Hello, first of all, this is a great site!

    I live in Toronto, Canada where they have also applied the low VOC law. I have a 5 year old cedar deck. I did not seal it right away after construction (big mistake). It greyed and got dirty over a period of 3-4 years. Last year, I tried to sand all of the fibers that have built up over the years. I then used a deck cleaner/brightener. Following that, I used the Benjamin Moore Arborcoat waterborne translucent deck stain. After the winter, I found that 2/3 of my deck has peeled off. What a massive waste of time and money. I was extremely disappointed and frustrated.

    I need some help from the experts! What should I do? I want something that will last and that I can trust.

    Question 1: From your past experience with other Canadians, do you know any products available in Canada that are good?
    Question 2: If answer is No to question 1, then I'll need to order a product in the U.S and ship it to buffalo for pickup. What do you recommend that I do to strip, clean and re-stain? Any help and advice is greatly appreciated!
    Question 3: Sanding was a huge job, can I avoid sanding?

    Thanks,
    Alan

    • 1. Sorry but not really. Does not seem anything decent is found in Canadian stores.
      2. You cannot strip the Arborcoat. It will need to be sanded. Once removed you will need to clean and brighten the wood. If picking up in the US then look at the Armstrong Clark in a semi solid color.
      3. No

      • Alan says:

        Thank you for your reply! Much appreciated. Here are a few follow up questions if you don't mind :)

        1. Can I get away with a Canadian sold product for the cleaner and brightener? or does this play a very big factor into the staining process as well?
        2. I used a hand sander last time and it took a very long time. Do you recommend renting a bigger unit from a big box store (if that exists) and what coarseness do you recommend for a cedar deck?
        3. Why do you recommend Armstrong Clark over TWP? Just to confirm, I am looking at a non low VOC product, if I'm able to get it shipped and pick it up
        4. Can you explain why you would recommend a semi solid color? I've used translucent on the railings and I love how it brings out and enhances the natural color of the cedar.

        • 1. Probably but stay away from bleach based cleaners.
          2. We use 60-80 grit for the paper. Large sanders will speed up the process.
          3. TWP is not allowed in Canada.
          4. Semi-solids will give better UV protection for this.

    Located in Georgia
    Brand new refurbished deck (less than 2 weeks old)
    Boards are Cypress, hand rails are Cedar
    Should I let the wood cure before staining, if so how long? Getting conflicting advice from contractors.
    What stain do you recommend for Cypress?
    What is the difference between TWP 100 & 200?
    Thanks

    • Yes on weathering in our opinion and always best to follow the advice of the stain brand manufacturer, not the contractors. 200 Series is for shakes and shingles while the 100 is for decks.
