Which TWP Stain Should I Use?

TWP stands for Total Wood Preservative. It has been around for over 20 years and has been a leader in the wood staining industry. TWP Exterior Wood Stain is an EPA registered wood preservative. Unlike other stains that cover up wood and form a protective film that is venerable to peeling and flaking, TWP stains are a penetrating oil formula that offers excellent protection. Knowing which TWP formula is best for your exterior wood project is the key to having excellent results.

TWP 100 Series – The 100 Series has been a leading and respected formula for over 25 years. It penetrates and enhances natural wood beauty and is available is 6 different colors. It is used for all types of exterior wood decking, siding, fencing, and hardwoods. It is not prone to mold or mildew. The 100 Series is not compliant in all states. Please be sure to check if it is compliant in your area. 

TWP 200 Series – Available in 8 different colors, the 200 Series formula is best used on wood siding, shakes, and shingles. It uses a non-drying paraffin oil formula that enhances the wood cell’s structural stability making it an excellent choice for older wood that has lost its natural oils. It sheds and repels water and prolongs UV fading. The TWP 200 Series is compliant in all 50 states.

TWP 500 Series – The TWP 500 Series formula has been discontinued and replaced with a new and improved formula called TWP 1500.

TWP 1500 Series – The new 1500 series replaces the old 500 series. This newly formulated preservative penetrates better, dries faster, and outperforms it predecessor. TWP 1500 is a low VOC preservative with unique absorbing pigments that prevent wood graying, fading and premature discoloring. Selected mildewcides prevent the growth of mold and mildew. Available in 9 different colors, TWP 1500 Series Stain is best used on all types of wood fencing, decking, siding, log homes and roofing. It is compliant in all 50 states due to its low 250 VOC formula.

Choose the TWP Series Stain that best fits your needs and give your wood surfaces the protection and lasting beauty they deserve.

    I live in Michigan. I have a 15 year old pine pressure wood deck that has never been stained. I am going to clean it with Restore-a-deck cleaner and use the brightener. Should I use the TWP 100 or 1500? Also, I just had a pine pressure wood railing put on. I plan to let it weather for year. Should I use 100 or 1500 on that? Thank you.

    I just had a cedar fence put up in the Seattle, WA area. It was finished in May. Should I wait four months to (September) or can I stain sooner? The constant rains start early. Also, should I use the 100 or 1500 series? Thank you!

      If it is smooth wood, you have to wait and prep. If rough sawn cut wood, you can do it now.

    I have 300 sq ft of pressure treated deck in central Vermont that gets intense sun in the summer and lots of snow in the winter. The deck was installed 11 months ago and ready for its first treatment. I am looking at the TWP products but am not sure whether to use the 100 series or 1500 series. What is the difference?

      Use the TWP 1500 Series.

        Difference is VOC compliance for certain states.

          I understand that Vermont does not require the more restrictive VOC levels. You still recommend the 1500 series?

    How long will the TWP 1500 series last on a pine deck in the woods with some afternoon sun?

    I used TWP dark oak stain on a vertical cypress beam with beautiful results. The beam fell into some bushes before it could be secured to the house resulting in greenish bark “juice” in a few spots. What would you advise?

    Can you apply TWP 1500 over the top of a deck that was stained with TWP 100 about 3-4 years ago and has been power washed? I really want to go with the lower VOC option.

    Does the TWP series deck stain have slip resistance?
    • We will reply to your comment shortly
      TWP Stains · 06/21/2019
      TWP is a penetrating stain. You cannot add slip resistance into a penetrating stain nor would there be any need.

    I live in south east VA on the Hampton harbor (salt water). My pier deck, 1 year old, which is salt treated (not marine grade) was pressure washed to remove the graying. Do I use the 100 or the 1500 series 2 coats by roller.

      Use the TWP 1500. Two coats applied wet on wet. Use a stain pad or brush.

    Would a TWP product be a good choice for finishing a Douglas fir front door in Wisconsin?

      TWP Stains · 06/17/2019
      No, it is not suggested for front doors.

    I live in Pueblo Colorado and get about 330 days of sun a year. I have 700 foot of cedar fence I am almost done putting up. After letting it dry good through the next few months which of your products should I apply and how long would you expect it to last in our climate?
    • We will reply to your comment shortly
      TWP Stains · 05/23/2019
      Use the TWP 100 Series. On a vertical fence, the TWP should last 4-6 years in most scenarios.

        Thank you. I’ve used a bleach/water/detergent mixture to clean the surface, which has been rinsed thoroughly. The siding looks good and clean. Is it necessary to use the wood brightener Before I apply the stain?

    I couldn’t find a list of states why the stain is allowed. We have a new (12 months old) deck of pressure treated pine. We live in Kansas. Which stain would be best? Also, my wife wanted an outdoor carpet under the furniture. Will this have any effect on the stain since that part of the deck wasn’t fully exposed to weather? I lifted up a corner of the carpet and it is slightly different color.

      Use the 100 Series. Best to put the carpet in the same spot when done.

    We are located in the Adirondack Mountains in Lake Pleasant. During the winter we remove the dock and stack the board sections outside. However, most years we receive a minimum f 4 - 5 feet of snow which may cover the stacked sections. The boards have been stained with oil base stain 5-6 years ago and sit in the sun from June through September on the lake n the dock frames. They are in need of re-staining.

      Strip and brighten the wood for prep and stain with the TWP 1500 Series.
