Difference Between TWP 100 and TWP 1500

 

TWP 100 or TWP 1500 Series DifferencesDifference Between TWP 100 vs. TWP 1500

The TWP brand of exterior wood and deck stain has been around for over 2 decades. It 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 comes in several different series of formula. 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 preservative. It is EPA registered and contains 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 Preservative 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 wood. If doing two coats, apply "Wet on Wet". The first coat is a saturate 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 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 surfaces 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. 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 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.

Preparing to stain cedar shingles on 10 year old home. Currently applied stain brand is unknown…it is a semi transparent oil based, but that’s all I know about it. Have applied several TWP samples over the past 2 years with no peeling, etc. Planning on using cleaner/brightener rather than stripper followed by TWP stain. Question..do I choose TWP 100, 200 or 1500 series?

Our deck is over 15 years old. It’s likely made of pine. It has cracks and shows its age. It also has a stain on it already that is peeling. Which is better 100 or 1500? Does the original stain need to be stripped?

We are also installing a new pine fence and want to use the same color.

Had a cedar deck installed last November/ December in west central Illinois. We were told to let it go through the winter before treating. We are now ready to treat. We like the natural weathered gray look of wood, but have been told if we let nature take its course, our deck will deteriorate guickly. Do you have a gray stain color that looks like gray weathered wood?

I live in Louisiana and built a 600 sq ft deck with pressure treated pine in March 2018. I expect to stain the deck with TWP 1500 in Sept or Oct.
1) Should I simply pressure wash the deck and/or do I need to pretreat the deck with a cleaning solution?
2)For a new deck, do I apply one or two coats of TWP 1500 initially,
or
3) apply one coat initially and apply a second coat in 6 – 12 months?

I have a 10 year old cedar fence. I used TWP on the fence 10 years ago. It is starting to fade in spots and could use a little refresh and darkening. I can’t remember if I used the 100 or 1500 series. Does it matter? What kind of prep will I need to get started. It is a two inch slat fence with two inch gaps between slats. Thanks!

5 years ago I had a new cedar fence installed. I first prepped the fence with Gemini Restore Kit to clean the oils on the wood. I then used TWP 100 Cedar Tone, now I would like to stain the fence again using the TWP 1500 Cedar Tone. What is the difference with using Restore A Deck Stripper or Gemini Restore Kit?

Hello – I live in Brooklyn and I’m planning on building a deck with premium PT lumber.
2 Questions:
1. Since I am in New York State, I am assuming I can only buy and use TWP 1500, correct?
2. In several posts here, and elsewhere on the web, you folks recommend letting the wood ‘dry’ or ‘weather’ for 4 months. If I buy KDAT PT Lumber, that is, “Kiln Dried After Treatment”, do I still need to let the wood dry for 4 months? (or does the kiln drying make this additional drying time unnecessary?)
Thank you.

I live in Austin, TX and just finished building a new 6 ft 3/4″ cedar privacy fence. The cedar is smooth on both sides. Four questions: (1) How long do I need to wait before applying a TWP product; (2) which TWP product do you recommend; (3) which color in a semi-transparent would be best to show the natural cedar color and variation in the cedar boards and (4) what is the process to reapply in a few years. I understand clear is not an option because it does not provide UV protection.

I have a cedar deck that is about 7 years old. It has never been stained. We just clean it every year. It’s in pretty good shape but is looking a little dry. I cleaned it two weeks ago with Behr all-in-one deck cleaner. I didn’t know about the Gemini products until now. Should I reclean and brighten with Gemini before I stain with the TWP 1500? Also, should I use two coats of stain considering it’s not a new deck but never been stained?

The 1500 series has more solids than the 100 series. Does this mean it is more likely to peel? I am currently dealing with Sherwin Williams deck stain that is peeling and don’t want to ever strip and sand the deck again. I live in Ohio and get lots of shade so I thought the mildewcides in the 1500 would be good, but am worried about it peeling more than the 100 series. Thank you for commenting.

We have a 25 yr old deck that we’d like to get a few more years out of. It was last stained several years ago with a Behr product that is water soluble. We have cleaned the deck with Restore-a-Deck and would like to stain it a darker color than what it is now (teak color is current color). On half of the deck, the stain has worn off but the other half is fairly intact. Do we need to remove all of previous stain to be able to use TWP stain since it is oil based?

I’d coated it with Cabot sealer and after 1.5 years it was peeling badly, looked horrible. I ended up pressure washing and sanding entire deck and am back to bare wood. I realize I need to maintain and reseal the deck every couple years but am looking for a product that will not flake/chip that I don’t have to sand… Read more »

In Arkansas, pressure treated pine decking, which should I use, 100 or 1500? It seems 1500 is marketed as being superior to 100, but it seems you usually recommend 100 over 1500 if it’s legal in the area? Pros and cons of each?

They are both excellent stains. Most use the 100 Series in your state. See this for differences:

have a cedar deck in St. Louis. We live in the woods so most of the deck has filtered sun. Those areas that get sun do so only about 2 hours per day. originally used Defy stain now looking to clean and use TWP 100 or 1500. How best to clean and which product would be best?

You cannot just clean. You have to strip off the Defy and then brighten the wood. Try using the Restore a Deck Stain Stripper and Brightener kit. Stain with TWP 100 when done.

Our deck has relatively little direct sun exposure. We are in lower Michigan. Would TWP 100 or TWP1500 be better for this application?
Also, how much addl. life span could we expect if we went with Cedartone rather than Honeytone?

Thanks!

Use the 100 Series. Cedartone gives better UV resistance over the Honeytone. About 2-3 years with Cedartone. Less with Honeytone.

When using the stripper on cedar siding, it’s easier to see the places that were missed the next day when the wood is drier. Is there any reason the brightener can’t be applied on the day after it was stripped instead of the day it was stripped?

TWPStainHelp
TWPStainHelp

Yes it is easier to see missed areas after it dries. Best to brighten as soon as possible. It neutralizes the stripper active ingredients.
