 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 am in louisiana and have new cypress beams that i have just planed and sanded down from rough (not an attractive rough, hence the finish). It feels a bit waxy, so im assuming we have glaze to deal with. I understand that it needs a lot of time before the 100 formula (assuming that is best) will absorb well and i see the recommendation to let them weather for 4-12 months. However i also see that they won’t be completely dry for years. Would it be feasible to just apply a coat now for some level of color and then reapply in a year or 2? The raw wood doesn’t match the house.

I’m installing 2×12 wire brushed douglas fir or cedar siding on a cabin in an area with extreme weather conditions of cold and snow. Is the 100 the better choice and applying all sides before the install? Once installed, I was wondering if you can lightly coat semi solid on to give it a unique color?

This is a northern Idaho location project. Variable weather conditions, extreme cold and heavy snow fall. Was thinking of using the 100 due to higher VOC 550 content. Is the semi solid VOC a 550 level? Always thought the higher the VOC, the better the penetration and weather resistant.

I have sealed my pine 6′ fence with TWP-100 (Dark Oak) twice over the last ten years and was planning to apply a third coat in December 2023. Unfortunately without my knowledge my neighbor to the rear sealed 100′ of my fence using a water-based solid seal made for fences and decks. He meant well and thought he was doing me a favor, but the damage is done. I am going to leave it this way for now, but want to know my options in the future as far as un-doing this damage. Luckily it is a run of fence that is mostly out of sight. I would like to know if I am able to strip this water-based seal off and restore back to bare wood – then applied coat-on-coat of TWP 100 (Dark Oak). If a stripper would work for this situation – which stripper would you recommend? I do know he only applied a single coat of the water-based seal.

I bet combining that product with a high-power pressure washer will get it off. I am hoping the adhesion is not that good for the water-based solid seal as they did not prep at all before applying over top of the old TWP-100.

The RAD ingredients make me weary – I am looking for something stronger (no odor= weak) product. I am going to look around for something stronger that gels – I don’t care if I have to wear a mask and it does not have to be environmentally friendly – the more odor the better (caustic=strong)

Northern Minnesota, rough cut Cedar lap siding.
I have used Olympic brand oil based semi transparent twice with good results- 10yrs and 8yrs before redo. That stain is no longer made.
I have high confidence in oil based products.
Which of your products would you recommend?

Which type should I use for a new fence? That’s mostly redwood but has some cedar and Douglas Fir. I’m not sure whether to do the 100 or the 1500. Or what the differences are. Also, where can I get this in Placer County California?

I am considering using the 200 series for our cedar siding that is 30 years old and  has always been treated with TWP 1/2 cedar tone 1/2 clear mix. We have stripped the old stain.  But I am concerned about the non drying parrafin oil. When it says non drying, what does that mean? Does the stain stay tacky?

I live in PA just soft washed my natural cedar home as it faded since I bought it. Currently waiting for it to dry. I want to keep it as natural as possible. Previous owner used Thomson Wood Protector Clear. Attached an old photo of and of it just soft washed.

1. Do I go with 1500/200?
2. Clear or Cedartone?
3. Can I mix the bug juice with it? I live on a creek and want to keep spiders off and carpenter bees away.

My 500 Sq ft deck has not been stained. It is “new”, having weathered for a yr. I live in Southwest Louisiana and we have very hot summers and high humidity. It is yella wood pine. It is not covered and gets sun most of the day. I am hoping to apply with a pump sprayer. Mold and algae are a moderate concern. Which TWP product do you recommend? Semi- transparent is preferred if possible. Will I need 1 or 2 coats as this is the initial staining?

Good evening. Planning on redoing the stain on my cider siding in Georgia. Probably at least 10 years since it’s been done and I have no idea what was used on it besides some sort of stain. Would the current stain need to be stripped to use one of your products?

We’re looking to re-stain the decks at our house in the Bay Area of Northern California. They were last done in 2015 with a 50-50 mix of 205 & 1501. If doing this myself then I’d like to switch to just one series – which should I use?

Getting ready to stain our 2- 1/2 year old uncovered pine deck for the first time. We live in KY, the deck faces northeast, gets morning sun, and backs up to a wooded area. As you can imagine,  it’s quite weathered, has  areas of mold, and some wood-splitting. What stain product would you recommend? As we’re not very timely with our home maintenance projects, a long lasting stain would be nice.

Hello, I love in the coast of oregon and gave a cedar shake roof. I previously used a chevron oil for preservative. Its 25 years old. The shakes have lost some thickness. Lots of rain, wind and salty air.
Should I use series 200 or 1500 series? Where is the closest dealer or can I order it direct from you?

I live in Colorado in some intense sun. About 7 years ago I stained my deck (skirting and railings) with TWP 100 redwood. It’s held up great, but due to fading and weathering, it now needs to be redone. However, I can’t order TWP 100 to Colorado anymore. Should I use TWP 1500 instead? Will it go over the faded TWP 100 okay or is there other prep work I’d need to do? And is the TWP 1500 redwood the best color match for TWP 100 redwood?

Would it look funny to use TWP 1500 Dark Oak for a porch railing and balusters I’m about to add when I already used TWP 100 Dark Oak on the deck and steps I’ve already built?  Everything is/will be built from redwood.  I ran out of the 1 gallon of TWP 100 I had, and it has since become more convenient to get TWP 1500.

I understand that even when using the same product, with some wood stains there can be a risk of slightly different colors, if all the cans used aren’t first mixed together to make it all uniform.

Is the difference in color between TWP 1500 and TWP 100 likely to be more noticeable than different cans of 100 that weren’t combined?
