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.

My contractor wants to use series 200 on my one year old deck. Would I be better off to have him use series 1500? How is your product tested? Do you use natural or accelerated methods? Where do you test your product?

Cedar deck built in 2012 on north side of lake house in Nebraska. Was stained with an unknown stain, then a few years later painted with an unknown paint.. Where the sun is on it full time, the paint is 90% chipped off. Where there’s full shade the paint is still intact. The wood underneath is in good shape everywhere. Would like the deck to be grayish to coordinate with composite decking nearby. What should I use? How should I prep?

New deck with pressure treated lumber built 11 months ago. Planning to stain with TWP 1500 Cedartone. Since there is no stain on it, do I need to use the stripper and brightener to prep, or just a light power wash?
Also, is one coat of the TWP 1500 advised for this new wood even though it is 11 months old?

My son is building a pole barn to be sided with rough-cut hemlock. We are considering the TWP 1500 stain but he wants a color other than the standard colors listed for your 1500 product. Two questions: 1) Do/can you provide other colors (if we supply a color-sample)? and 2) Can the ‘clear’ TWP 1500 be tinted/colored locally, and if so, are there special pigment requirements?

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.
