Difference Between TWP 100 vs. TWP 1500

The TWP brand of exterior wood and deck stain has been around for over 2 decades. the TWP 1500 is the only registered EPA wood preservative on the market today. It is made using only the best quality raw materials to offer superior wood protection. TWP Total Wood Preservative/Protectant comes in several different series of formulas. Knowing the differences can help you to make a more informed decision.

TWP 100 Series Stain

The TWP 100 Series is the original formula of deck stain and Protectant. It is an exclusive blend, which protects wood from becoming damaged. This particular series of TWP wood stain has been respected for over 25 years.

TWP 100 Series Wood Protectant penetrates the wood to enhance its natural color. It comes in 6 varieties of wood tones. It will prevent the wood from turning gray by blocking out harmful sunrays and has exceptional water-shedding properties.

The 100 series is not prone to mold or mildew and is best used on wood siding, decks, fences, and hardwoods.

TWP 100 is restricted in 36 states due to higher VOC levels. It cannot be shipped to these states: California, Connecticut, Rhode Island, Maine, Massachusetts, New Hampshire, Vermont, Delaware, District of Columbia, Maryland, New Jersey, New York, Northern VA, Pennsylvania, Parts of Arizona, Ohio, Illinois, Indiana.

TWP is about 30-40% in solid content. It absorbs very well and dries in 2-6 hours for most scenarios.

1-2 coats depending on the age of the wood. If doing two coats, apply “Wet on Wet“. The first coat is a saturating coat, followed by a light coat to ensure absorption and even application.

TWP 1500 Series Stain

The new 1500 Series low VOC formula wood stain is compliant in all 50 states. The 1500 series wood stain is formulated to penetrate the wood better, to dry faster, and outperform previous versions of TWP stains. It is also a registered EPA wood preservative.

TWP 1500 Series Deck Stain stops structural damage caused by wood rot and decay. It enhances and prolongs a wood surface’s natural color and eliminates graying. It resists water and moisture, which can cause warping, cracking, splitting, and freeze/thaw damage. TWP 1500 uses mildewcides that help eliminate the growth of mold and mildew.

TWP 1500 is roughly 60-70% in solid content. The absorption rate is a little slower than the 100 Series and dries in 4-12 hours for most scenarios.

1-2 coats depending on the age of the wood. If doing two coats, best to apply two light coats “Wet on Wet“.

The new Total Wood Preservative 1500 Series Stain is easy to apply and maintain. It will keep your exterior wood surfaces beautiful and protected for many years to come.

We will be refinishing a log home in the Upper Peninsula of Michigan. Cool climate – quite a few trees nearby. We will have the home media blasted to strip it prior to staining. I am wondering if the 100 series of the 1500 series is the best option for this application? Thanks.

I will be applying TWP 1500 natural cedar to my cedar deck once i receive the shipment (later today). There is a chance of rain in the forecast Friday. I will likely need through Thursday morning to finish. If rain does come Friday, can I cover the deck with a thin plastic tarp to keep the water from hitting the deck? and if it’s ok to do so, will there be any consequences?

so if I apply tonight, and it rains Friday morning, I should have enough time? Also, I read that applying TWP over a different brand of stain could cause problems. I applied SUPERDECK Transparent Stain over 2 years ago on a freshly sanded cedar deck and rails. I cleaned the deck a few days ago and it appears there is little residual stain on the deck floor; however, the rails appear to be holding the stain. Do you think i am ok applying TWP on the deck floor?

I am fabricating adirondack chairs using cedar. The cedar has been stored indoors for minimum 6 months. The boards are 2×8 rough cut and 1″ deck boards. After thickness planning the boards, routing and or sanding to shape, radius routing edges, they are sanded with 80 grit paper on an orbital sander to remove fabrication marks. Then followed with 60 grit paper hand sanding with grain.
I would like to stain/seal each piece individual prior to assembly.
Current moisture reads 10-12%
I know the new wood is not ideal for staining.
Is there an additional proceedures or chemicals to use for better absorption?
I prefer to use a semi transparent stain.
I appreciate your time and any help you can offer.

In using the Brightener will it open the pores enough on new wood prepped as I explained to allow your 100 stain sealer to soak in without having to weather the wood for sometime?
Thanks for your time.

  1. would the 1500 be overkill?
  2. which color / tone would give it the most natural look?

I am going to stain a new pine wood deck, can I start off with the 100s then switch to the 1500s in the future? If so, 1 or 2 coats and when would I start using the 1500? We can use the 100s where I live.

I applied the 1500 series in 2012. My contractor applied a Valspar semi transparent over it 2 years ago (clean up soap and water which indicates it was latex). It is now pealing and bubbling. I had a contractor power wash it today but it’s just peeling up in strips. How to fix this and start over with the 1500 stain? The RAD stripper and brighten solutions? Can I use a transparent stain or will I need a semi transparent stain? Thank you.

It was very difficult fir me to remove the several layers of ore-existing paint from my deck. I incorrectly used the Behr stripper product with a power washer. It took roughly 6 or 7 separate applications and countless hours of power washing. As a result – I over powerwashed when stripping the pre-existing paint. Now my deck has uneven levels & grooves as well as “deck fuzzies”. I just purchased the Gemini kit and am planning on purchasing the 1503 dark oak. Please advise on the following;

1) what sandpaper grit should I use when pre-sanding prior to applying the cleaner and brightener? I’d like to go as deep as possible given the unevenness, fuzziness, groves, and potential for foot splinters, but I do not want to impede proper absorption of the 1503 stain.

2) what is the best (and easiest) method for applying the stain once I’ve sanded, cleaned, and brightened? Can I use something like the homeright deck pro listed in the link below?

3) how long does it take (estimate) to ship to Ohio?

4) do you recommend one coat or two?

Hi I live in St Louis MO and built a deck last Fall. The treated yellow pine is ready for staining and I am interested in your 100 or 1500 series. Most of the deck gets sun from early afternoon to evening.
1) I’m not sure which series to choose, would it matter?
2) I like teak color as it doesn’t pull too much yellow or orange but it is still light, would Pecan be the closest color to that?
3) With this being a new unstained deck, do I need to use your gemini cleaner and brightener or is a different prep involved?

I have a large detailed house and barn with TWP applied in 2012 again 2017 and some again 2020 because it’s starting to look fading and dry in som places but every time they do it it looks bad ( different shad and overlaps like where it was dryer and where it would not penetrate in the wood like it wasn’t ready yet it’s like it repelled itself in some areas how do I fix this? Stripping the whole house sound crazy. If it repels water dose it need it?

I stupidly put two coats of series 100 on a box of new red cedar shingles…..did not read your website carefully enough (and my hubby said to do two coats). The stain did not fully absorb…..they feel a bit greasy.
Did I ruin the shingles?

PS My hubby only went to the “dog house ” for a day!

Thanks!

I’m making some picnic tables for a restaurant out of Kiln Dried After Treatment Pressure Treated lumber. These tables will be subjected to the normal punishment of the elements, plus regular wiping and abuse that tables at restaurants endure, so I’m looking for the most protection I can get.

We don’t want anything opaque, as we still want the grain and character of the wood to show. Which of your translucent products would you recommend for this project?

I am preparing to re-stain my treated pine deck, which is over 10 years old. This will be the third time in 7 years that I use TWP1500. The painter has suggested using a clear sealant after the stain dries. Do you advise that I do so, and if so, what type?

Have a deck with Pergola above part of it, in Alabama with extreme heat in summer. The deck has never been stained, and was built 3 years ago.
I lnow the gemini cleaning kit is needed first…my question is on choosing the right stain. You now sell the new Semi Solid Pro, so what would be the advantage or difference between using the 100 series ve the Semi Pro? Will the semi pro last longer? Give better protection? Just trying to make the best choice, and would love to not have to restain in 2 yrs, if that semi pro would accomplish that!

Can you send me a small sample of your product that you most recommend for my deck? I want to try it on a small patch of the deck to see how it looks before I commit to doing the whole deck. Thanks.

We just changed our plaster columns for 10×10 rough cypress columns. Do I need to do anything to prep these columns before I stain them? There is no consistent answer that I have found online. Do they need to be cleaned, sanded, anything? I have a sample of both 100 and 1500 to try on some scraps before doing the final project.

After extensive research I applied the TWP100 Redwood Semi transparent stain to my 20 year old deck. Prior to application I had to strip the former stain until completely removed.
I have been extremely pleased with the product. The wood is still sealed after 2 years. Water will form beads in most areas of the deck
However, the color was too red so I would like your advice when restaining. Also, I live in a very dry climate so the wood has some splitting and showing signs of age.
Due to the cracking and color choices i am thinking I should switch to the 1500 series and use the California Redwood.
Do you agree and do yu have any advice
Thank you

I have built a dock on my 7 acre pond that has pressure treated decking that has weathered for 4 months. The rest of the wood (railing and some interior wood in screened in porch) is not pressure treated and is relatively new, only having been in place for a couple of weeks. I am wondering whether you would recommend the 100 or 1500 products for this use. As you can imagine, the summers here can be quite sunny and hot…average temps in the middle of the day around the middle 80’s to middle 90’s. I would like some advice on application as well. I would prefer a phone call to a qualified and experienced person to discuss. My name is Charles Leavell, phone 478 9513749

I have been using TWP 100 every few years. It appears your TWP 1500 is more UV resistant, so I was going to switch to that, as I believe I need protection from the sun more than anything else. Any special considerations using the 1500 after the 100? I am planning on using the cleaner/brightener prior. Thanks!

2. Do I need to wear a respirator.
