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.

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… Read more »

I am looking for a wood preservation as opposed to a stain. My 2 x 4 fir deck is now a good 10 years old and has never been stained but could stand some rejuvination and preservative. Any suggestions?

I live in S.Carolina and have a 35 year old deck that is still in pretty good condition. i have been using TWP 101 Cedartone stain every 2 years for about the last 10 years. My questions are: 1) Is there any reason to switch to TWP 1500 series? 2) Will switching to the Honeytone color actually lighten the color of the deck at all?

I applied TWP1500 7 years ago. Am I well advised to stick to semi-transparent, or can I switch to solid stain ? What prep product should I use before I re-stain ? Please advise. Also, what about the boards that I need to replace ? I can’t wait another year to stain !

I purchased a clear cedar wood garage door that was built in Southern California approximately 4 months ago. Due to COVID, the company kept it in their warehouse until recently. It is now on my back deck under a tarp. How long should I wait until I stain the door? Also, do I need to sand or prep the wood? It is clean and high quality.
Thanks in advance. I am a huge fan of TWP!

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… Read more »

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!

I’ve been using TWP 100 in North Carolia for years and love it’s ease of use, protection and durability. As I get older, the strong odor gets to me. 2 questions:
1. Can I apply 1502 over 102 same color. That’s if the 1502 odor is less?
2. Do I need to wear a respirator.

Thank you,
Joe

I live in MN, I bought a house with an old cedar deck, probably 25 years old. I have sanded down the entire deck. Still don’t understand if I should be using the 100 series or the 1500 series? My wife seems to like the colors of the 1500 series better but I want whatever is going to be the most durable/last the longest.

I live in Michigan and have a cedar deck that was completed in November of 2017. It has never been treated with anything since it was built. I assume the Gemini kit is required to clean first but not sure which stain is better to use for this application, TWP 100 (cedar tone) or TWP 1500 (cedar tone). Which do you think will work best?

I have a pressure treated pine deck in western Kentucky about 8 years old. Never stained. Only clear water seal in past. It was pressure washed a week ago and he used some household bleach as well. It’s raining off and on several times a week. I was going to now use Gemini clean and brighten product when I get some consecutive dry days then stain. Is that ok after pressure wash and that bleach? I was going to use 1500 series but I see you recommend 100 series to some. How do I know if I need 100 or… Read more »

Hello, I have a 20 year-old straight-grain Douglas Fir deck located in western Washington on Puget Sound that was previously coated with an acrylic solid stain. This stain is mostly gone and will be completely removed with a full deck sanding. There is black mildew staining and graying. I live in a wooded area that has lots of rain/moss/algae in winter, but the deck is in full sun during the very dry summer. The deck is fully exposed year-round. Snow is rare but freezing is routine. Most of the decking is old-growth and in good shape. My questions are: Is… Read more »

I have 10 year old cypress cabinets in an outdoor covered patio. They get full sun from the west in the afternoona nd evening here in Louisiana. The cabinets were stained and polyurethaned twice in the past by two different painters. The marine urethane has never held up. It is peeling and the cabinets need to be sanded and redone. Is TWP 1500 a good option for cypress? If so, can you please provide any information for prepping the cabinets before applying? Any instructions for applying the TWP. Thank you in advance.

Have a epi deck that was previously stained with twp. He said he used 200 series butternut but owner said too orange. Said he mixed 100 series dark oak with 200 series butternut. Trying to match up color to restain. They like the color it is now. Any suggestions? Don’t have a problem trying to match up on some scrap epi. Do you see any issues with mixing 100 series and 200 series together.
