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 SERIES penetrates deeply into wood without excessive surface film build, highlighting existing grain patterns with amazing clarity and warmth and is specifically designed to provide protection against the four major causes of wood degradation: wood rot, water, sunlight & mildew.

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

TWP Deck Stains – 100 Series Review

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

Appearance After Initial Stain Application: 9

– We prepped the deck first with the Gemini Restore Kit and applied the TWP 120 Pecan color after a few days of drying. This deck was originally done with the TWP 101 Cedartone. The customer wanted to use the Pecan this time as it has a slight “brown” tone. The overall appearance was excellent.

Preventing UV Graying at 2 Year Mark: 8

– Same as the first time tested, The TWP Pecan 120 retained about 80% of the original color after 2 years of full exposure to the elements.

Wear/Tear and Peeling: 9

– Very minor or no wearing of the TWP. TWP penetrates very well into the wood grain so this is normal and expected.

TWP 120 Pecan

TWP 120 Pecan

Cost Per Square Foot: 8

– The price paid was $170 for the 5 gallon pail of TWP 101 Stain. We used 6-7 gallons for our 700 sq. foot deck. Total amount for the stain cam to $240 or .35 cents per foot.

Preventing Mold/Mildew/Algae: 9

– No mold or mildew. Some green algae along the edge, near the home.

Ease of Application: 9

– We use the suggested TWP application of “wet on wet”. Pump sprayed on the first coat for the floor very lightly and applied the second coat with a pad applicator to ensure an even appearance. Railings were stained with a pad and brush. Overall, we applied the TWP stain in a few hours to the 700 sq. foot deck and a team of two employees.

Color Shifting (darkening) after 2 Years: 9

– The TWP did not darken from mold or UV discoloration.

Difficulty of Reapplication: 8

– Reapplication will be as easy as using their Gemini Restore A Deck Kit. One of the kits will be enough to clean and brighten the deck for reapplication. No stain stripper will be needed to remove as the TWP has faded lightly and evenly over the last few years.

Overall Score TWP 100 Series Stain at 2 Year Period: 8.5

– Once again the TWP is one of our most commonly used stains. We personally have applied the TWP 100 Series to many 100’s of decks and rarely have an issue. Easy to apply and easy to reapply when the time comes. There are a few other stains that are as good, but as of yet, no other product has been better.

Note: We do not use TWP on brand new wood. If applied to wood that is less than 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 and only apply one coat for wood that is 4-12 months old.

  1. Ben Green says:

    I have a four month old mahogany deck. Is the TWP 100 a good choice? How much will it change the natural color and is it California compliant?

  2. Jack says:

    When using kiln dried pine is it still necessary to wait before staining? If so, how long?

  3. Patrick says:

    I live in the sf bay area and am looking to restrain my deck. The deck is an old redwood deck on the 2nd story facing north east with very un even uv exposure, some parts of deck gets intense direct sunlight and other areas very little. I found some old behr arborcoat stain in a closet from previous owners, so I am assuming this is what the decks got treated with previously. The underside of the deck has a lot of black mold and moss but the top of the deck boards look in good shape, they are just greyed. Would you recommend the TWP 1500 formy situation? Should I treat the bottom side of the deck with something else? I have also read some good reviews of the one time stain. What would you suggest?

    • Deck Stain Help says:

      TWP 100 is not allowed in CA so yes you will need the TWP 1500 series. Make sure to prep by removing all the previous coatings. No need to stain bottom sides.

  4. Mark michel says:

    Can this product be used inside ? I have rough cut pine interior walls of an old house that looked good until the recent Louisiana flood. We cut at 30 and removed boards and pressure washed. Put back in place but there is some water stain marks still remaining. I want to stain the wanes coat boards and put a molding on the joint.

  5. Kevin says:

    I just installed a tight knot cedar deck and want to protect against the elements without much pigment. Your review says to wait 4 months for new wood. That would make it February and in Seattle I'll be lucky to have 3 dry days in a row for drying and application. Thoughts on what and when to use for protecting? Should I use a cleaner beforehand as well? Large dogs will be playing on the deck immediately. Gets limited sun.
    Thanks, kevin

  6. Marvin Wish says:

    Our deck is made of pressure treated pine.
    We had it installed June, 2016.
    We have maybe 50% sun (if that) on the deck with very little foot traffic.
    Please let me know if I should treat the wood prior to staining and what products to use.
    Please also advise on the stain/water repellent to use.
    I really don't want the deck to consume my life every few years.
    Thank you,


  7. Judy Rogge says:

    We have a pressure treated pine deck that has two year old floor and rails but has spindles that have been on for at least ten years. It is stained with Shermin Williams Deckstain that starts peeling after less than a year so the floor is peeling pretty good. We have a good pressure washer also. Should I stain before winter or wait till spring? Shuld we just pressure wash or use product on it first? Does TWP make a color that matches Shermin Williams Deckstain Cedar Bark Semi Transparent?
    Thanks for your help.

  8. Cheryl Duncan says:

    Our deck as built 8 months ago with pt pine and has not been stained before. We live in the Piedmont area of NC and have partial to full sun. A friend recommended Sikkens, but after reading other reviews I am back peddling in that advice. Is the TWP 100 the best product to use on our deck in your opinion and is there any prep work or advice you can share? TIA!

    • Yes you will need to prep. They suggest their Gemini Restore A deck kit for the prep. Only one coat this year and apply another light coat to the floors in 12-18 months. Every two years after that.

  9. Joe H says:

    Have a six year old cedar deck in St Louis area. Have had to replace some floor boards, and a railing post. October now. Should I wait til spring to strip SW deckscape? Will new wood blend in with old using TWP 100 pecan stain?

  10. PKK says:

    We have a 1950s house with a painted covered deck. Contractor sanded off paint to bare wood (pine). Can we stain right away or must we wait?

  11. Greg Dallas says:

    Read reviews here. They were great guidance. Great choice for replacing Behr stain that failed almost immediately. I had never heard of them. Product shipped promptly direct to my home for less than comparable product from local big boxes. Just finished 3rd year of withstanding Texas heat

  12. Just stain the exposed side. Wait until Spring and prep first.
