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.

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.

    And can I clean with pressure washer? Any other prep or cleaning solution?

    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.

    I have a freshly cut cypress beam for a mantel. What should I use to coat the mantel? I have been told linseed oil for a natural finish so the mantel can continue to breathe. Suggestions?

          TWP is a penetrating stain and does not film on top of the wood. Wood doors need a protective barrier that is film-forming similar to a polyurethane. This helps with the doors weather seals in extreme heat. TWP cannot be top coated with a polyurethane.

            TWP,
            I stained an exterior door (smooth finished cedar) with 2 coats of series 100 dark oak, let it dry 48 hrs, then used a soft cloth to wipe down the door until stain no longer transferred to the cloth. Afterwards, i lightly sanded the surface with 400 grit sandpaper, cleaned the surface throughly and applied two coats of varathane spar urethane. It looks great two years later. No flaking or cracking at all, even in the hot Texas sun. Absolutely love TWP products.

    I applied TWP stain on my deck after sanding it and it doesn't look good. Can I directly apply a semi solid stain on top of TWP stain?

    Can I use for interior walls?
    • We will reply to your comment shortly
      TWP Stains · 09/11/2018
      You can but the TWP will have a very strong odor on an interior application since it is oil based. It will dissipate but it could take awhile.

    Hi, I moved into a house with a large three year old (old growth) cedar deck that was treated with TWP 1500 series. I am in WA state and after only three years the deck was covered in mildew spots with tons of cracks in the floor boards. After cleaning with Behr all in one wood cleaner, the color is much brighter and much of the mildew is gone. Do I still need to use the restore kit or will the Behr suffice? Also, should I use the 1500 series again or the 100 series? I'm not really clear on what the main difference is between the two.

      Best to use the Gemini Restore Kit for proper prep. Use the TWP 1500 again.

    Is TWP a stain or oil? I have a deck that has previously been treated with oil.

      TWP is a semi-transparent oil based stain. You will need to remove any previous coatings before using the TWP.

      The TWP 200 would not be the best option for the Mahogany chairs as it may rub off. Use the 100 or the 1500 Series.

    I recently cleaned, brightened and restained our screen porch floor with TWP 100 pecan in anticipation of converting the screen porch to a glass enclosed sunroom. The glass walls were installed today and there is a residual odor from the stain which was applied two weeks ago. Will these fumes ( they burn my wife's eyes) clear or do I need to remove the stain? How long should it take for the floor to cure? It has been dry to the touch for over a week.

      The product cures within a week or so. The smell may linger longer if enclosed fully air out as best you can as it will not be a permanent smell.

        So, these fumes are not harmful to breath?

    Ada rogers:
    Going to stain new cypress boards before they are installed for the soffits only on one side. Does the wood have to cure before staying with the twp 1500?

    Is the wood rough sawn or smooth wood? See this about new wood:
