TWP 100 or TWP 1500 Series DifferencesTWPStainHelp.com Tips: 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 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.

While waiting for our deck to weather, we are noticing some black mold and mildew spots. Is there something we should be doing and/or using to spot clean this before our actual clean/brighten/stain days?

We have cedar siding and a fir deck. We are using 1500 Cedartone. The color difference is stark and the two colors do not compliment one another. The fir deck stain sample is much darker and considerably more red-toned. Can you recommend a different color for the deck, to counter-act the red and compliment the Cedartone ? Also, as a possible alternative solution, do you have a semi-solid or solid Cedartone to achieve a closer cedar color for the deck?

I’m leaning towards TWP 1500 as that seems to have a longer dry time in order to stain wet on wet. I’m staining a cedar fence we put up last year and left up to let the grain open up a bit. However, it grayed a bit and I’m thinking of cleaning and using a brightener on it. Will that defeat the purpose of letting it sit this last year? My understanding is that the brightener (oxalic acid) takes off the top layer of fence material. Or is that false?

I have used the 100 series for my deck railings and stairs in the past. I am trying to finish a project but currently the 100 series is out of stock in my area and the distributor said that I can mix a new 1500 series pecan color with the 100 series pecan and dark oak that I have, and it would be fine. He also said the 1500 series is a superior product especially for vertical surfaces such as log homes whereas the 100 series is meant for decks. He also said there were 30% solids in the 1500… Read more »

After reading, and re-reading the info, I’m still a bit confused. We have just installed a new deck in Minnesota.–cedar-toned pressured treated pine. What would be a correct wood moisture meter reading in order to be able to apply TWP? We want to do a “picture frame” application with dark tones around the edges and cedar tone in the middle. It sounds like the 1500 series has more solids and a deeper color. Is that correct? Which would be better for our location — 100 or 1500, and why do you say that?

Last month I re-stained my front porch (15 year old cedar) for the first time since I initially stained it with TWP 1503 two years earlier. Before re-staining, I prepped the porch with the RAD treatment and made sure it dried out for two days before and then it was dry for two days after I re-stained it. After I finished re-staining, I used terry cloths to soak up any excess before it dried. Everything looked great, but I’ve noticed what looks like excess stain seeping through the cracks to the surface of the wood. I rubbed it, really hard,… Read more »

I have an older wood fence/ house panels that I am wanting to buy TWP 1500 for:
1. Would two coats last longer than 1 coat would?
2. What sort of maintenance do I need to do in the future for this stain (ie, strip and restain in X amount of years from now or just paint over the TWP coat again)

I live in Wisconsin and want to stain my deck a gray color (Cape Cod Gray). I have used the 100 series for many years but would like to step to the 1500 series for this project. Do you offer a Cape Cod or Driftwood Gray color in the newer 1500 series of TWP stains? If I need to order the 100 series to get a gray color tone, why is this more expensive than the other colors in the 100 series of TWP stains? I do want a semi transparent and not a solid color stain. Please clarify.

Hi. At this point I am still in the throws of the prep. It has been quite a process since I have been removing a Sikkens product. Still need to sand and then brighten and let dry. The weather has not been our side this summer so not sure when we will get this accomplished. If you want a pic soon I would ask the community to have someone forward a shot taken recently. Such is the world of working outside! Best of luck.

First treatment- semi transparent stain (oil and some brown color, 2 coats), don’t remember the brand, but bought at Lowe’s, turned a dark color, was ok but “looked” hot. Second treatment -Semi transparent stain (lighter) About two years later, applied 2 coats semi solid, red cedar – it was ok but can no longer see the wood grain but ok because… Read more »

I stained my deck about 18 months with TWP 1500 Rustic. I stripped and brightened before hand with Restore-a-Deck. The color has faded a lot more than I expected for that amount of time, especially in high sun areas. A water test shows that the boards are not beading water. I am ready to stain again and do not want to strip again. Should I have done TWP 100 originally instead? If so, is it ok to stain over 1500 with 100? I live in TN, so VOC laws do not apply.
