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 a town that gets all 4 seasons including snow and lots of sun. I want to stain my house, deck floors and fence. My house has wood panel siding, my decks are redwood wood and some my fence is regular untreated wood fencing. Which series(s) should I use?

    I have a 15-year-old PT wood deck previously stained/painted.  I have recently replaced some boards, approx 4-6 months ago, and have stripped, sanded, and cleaned the deck.  The deck has a southern exposure and we are in northern Virginia.  Which type of stain would be best? TWP 100 series or 1500 series.

    Cypress siding has dried 2 years, planed and shiplapped. I am interested in a Redwood or Mahogany stain. Which semi transparent TWP product will provide more UV protection? Also what product is best to treat end cuts?

      TWP does not come in a Mahogany color. The TWP 100, 200, and 1500 series are all semi-transparent and all give the same UV protection. You do not need to treat end cuts but you can with any of the TWP stains.

    I thoroughly  restored a pressure treated deck with Cedartone 101 and it looks new. Can I use 1500 series over top of it for maintenance coats?

      If switching series you should strip and brighten for prep: https://www.twpstain.com/restore-a-deck-stripper-brightener-kit-detail

        Thanks for the quick reply, but just to be certain, I just did it last year, deck’s in perfect shape. Are you saying the 1500 won’t hold up on top of the 100, or it will look weird or? Also, might want to check the question from 6/11/2019, person from Nebraska says they started with 100, and if Nebraska changes it’s VOC laws, would the 1500 suffice, and the reply on 6/12/2019 was go ahead, use the 1500 on top of 100. Obviously I don’t want to have the extra work if I don’t have to. Just trying to clarify, thank you.

          For best results you should strip and brighten when switching. Stripping is not any harder than cleaning. Same exact process just removing the current stain so the new coating will fully soak in and give a uniform appears. On another note, the colors in the 1500 are not the same as the 100.

    I have a pool deck that seems to need a yearly stain as the chlorine washes the big box stains off in one season. I have replace the decking 2 years ago and want to apply something that will last.

    We are installing wester red cedar vertical grain siding and using the same for a deck as well. We want to retain the lightness of the wood and also preserve the warmth (not let it turn overly grey) but don’t want a red tone. Live in Bay Area. (CA) would you recommend twp100 or twp1500 and what shade?

    I've had great success with TWP 1500 for staining a Redwood deck and fence here in Northern California. Now I'd like to stain an wooden outdoor dining table. I'm not sure of the wood type - possible eucalyptus. Would you recommend TWP 1500 for this purpose? I've seen TWP 300 advertised for furniture. What is the difference? Thank you.

    I have a Rainbow redwood playset that has already been stained in twp200. Should I do that again? Or move to 1500? It is about 5 years old and has been stained twice.

    Located in North Texas, TWP 1501 was applied our fence about 4 years ago. Before we stopped him, a worker applied TWP 1501 to an already stained section instead of a new section. It turned darker and is shiny. The stained section is on the side of the house that out of sight. What do you suggest? Will it hurt if we just leave it alone? Thanks.

    wanting to protect cedar shingle siding accents that have minimal weathering, prepped with sodium percarbonate to remove mildew, brightened with oxalic acid and rinsed. Shingles restored to almost new appearance; not wanting to darken too much. Contemplating TWP 100 or Restore A Deck semi transparent waterborne, both in lightest tints. Probably 250 sq. ft., no previous coatings.

      Honeytone is the lightest TWP tint and enhances similar to a clean wet look.
