The new TWP® 1500 formula is designed to penetrate better, dry faster and outperform the previous TWP® 500 series formula.

TWP® 1500 Series is an EPA registered wood preservative which prevents structural damage and wood decay on exterior above ground wood surfaces such as untreated or previously treated fencing, decking, wood siding, log homes and roofing. TWP® 1500 Series resists water absorption that causes warping, cracking and splitting as well as preventing freeze damage in colder climates.

TWP® 1500 Series is a low VOC preservative with special U.V. absorbing pigments that prevent unsightly wood graying, darkening and fading. The selected mildewcides inhibit the growth of mold and mildew which assist in preventing premature discoloration.

TWP® 1500 Series will keep your wood beautiful, fresh and looking new longer. The ease of application and maintenance will allow you to enjoy your investment for years to come.

Yes you can blend the TWP with other colors of the same series. We do offer samples for testing:

Blending colors
I live is a damp wooded area in Pennsylvania so I have decided that the oil based TWP 1500 series would be best for my deck. I will need almost 10 gallons of stain. In my quest for a more custom color my question is has anyone ever combined two stain tints with success? I am thinking of combining (1516 Rustic with 1503 Dark Oak) or (1504 Black Walnut with 1502 Redwood)

How about shelf life of product
Thank you for the response - what is the expected shelf life of unused material...TWP 1515

re: TWP 1500 VS TWP 100
Since you have already used the 1500, it would be best to stay with it. You can clean and brighten the wood for prep. No need to strip. If you wanted to switch to the 100, you should strip as it is a little thinner in consistency than the 1500.

TWP 1500 vs TWP 100
I applied 1515 to PTP deck 4 years ago. After thorough deck cleaning with cleaner/brightener and power washing, I am ready to reseal. Looking for guidance between the 1515 and 115 sealer. I live in Michigan. Also, since I would be putting TWP over TWP I assume there is no need to strip. Please confirm.

150-200 Sq. feet per gallon for the first coat. Second coat applies at 250-300 sq. feet.

Deck Stain

I live in upstate South Carolina and I have an 11 year old deck that needs to be restored. I had to replace a few of the old floor boards the other day and I am trying to figure out what stain will work for me. I wanted to go with the TWP 1500 originally but am concerned about the new wood not absorbing the stain and having mismatched colors. Should I go with a full body solid stain to be safe? If so, what should I use?

Samples are on this link:

Either one of those stains would work well for you. I would suggest the samples and picking the color you like the best.

Product questions
I live in southwest Florida. We have built one large deck from PT and are planning to start a second even larger one next weekend. I know I need to let the decks dry for a couple months before I stain them so I am researching stains/sealers. Due to our very harsh sun, humidity and rain, I have become convinced that the big box store brands are probably not my best choice. I am undecided between TWP 1500 or the Armstrong-Clarke. I prefer the TWP colors but I like that the Armstrong Clarke can be applied in the full sun and heat. I don't see the application instructions here for the products so any advice would be appreciated. Also is it possible to get samples? I am going to wind up with over 1200 sq ft of decking and pergola so I would like to be able to see what the actual color is going to look like before ordering that much stain.

Thank you,

Lisa Brower

As stated above, TWP is not allowed in Canada.
TheSealerStore , May 13, 2014
I would like to order TWP 1500. You have responded previously to others to say that it can't be shipped to Canada. It says in this press release that TWP is available online to ship to Canada through Sealer Store:

Toronto Canada , May 13, 2014
No the TWP 1530 is tinted, not clear. If it does not have a tint then it will not prevent UV graying. Only the 1500 for NJ.
TheSealerStore , June 24, 2013
Is 1530 (natural)of TWP 1500 colorless? I do not want to add any color on our pressure treated pine. We live in NJ so TWP 100 would not be available to us, correct?

Light but protected
Hi! I know that light colored stains don't protect as well, but we really enjoy the natural beauty of our "new" deck (its>9 months old) so were thinking of going with Honeytone or Natural. Which one would provide more protection?

Allison , May 05, 2013
re: pictures of houses
Sorry but we do not. Final colors will vary though depending on wood type, age of wood, how applied, etc. Best to get a few samples to test before you buy in bulk. Stain Samples
TheSealerStore , April 05, 2013
Do you have any pictures of houses with any of the stain colors?
Karla , April 04, 2013
re: Coverage for a Cedar Pergola
TWP suggest waiting 4-12 months to stain new wood. Clean and brighten new wood before staining is required. Only 1 coat on newer wood. For the 1 coat you would need 6-8 gallons
TheSealerStore , October 01, 2012
Coverage for a Cedar Pergola
I have a new cedar pergola, wth the main cedar posts/beams/rafters being moderately rough. I have approximately 1200 sq. ft. of surfaces to stain. How much TWP 1500 to cover the 2 recomended wet-on-wet coats?

re: black mold 2 months after cleaning, brightening, and staining with TWP 1500 !!!!
TWP does not promote mold growth so it has to be one of the the two mentioned. I am 100% certain it is not the stains fault.
TheSealerStore , July 26, 2012
re: black mold 2 months after cleaning, brightening, and staining with TWP 1500 !!!!
Thank you for your reply. I do not believe either situation you described happened because the wood looked really good before and after prepping, no spores. Second, I waiting until all the pollinating was done to prevent problems from happening.

I will do as you recommend with the 1 part bleach to 5 parts water mixture.

I have to tell you I am quite disappointed with this. We've had a deck in this location before and just replaced it and enlarged it and never had this problem with acrylic stains....

re: black mold 2 months after cleaning, brightening, and staining with TWP 1500 !!!!
Mold can grow on top of any surface. Stains cannot stop this but they can prevent it from growing in the stain. TWP contains an EPA registered preservative that prevents this. One of two things probably occurred.

1. The mold spores where in the wood prior to staining and where not not completely killed when prepping.
2. A tree in the area was pollinating during the process and got caught between the wood and the stain. This can cause mold spots.

I am assuming the second based on the 2 months. At this point I would take a very light concentrate of 1 part bleach to 5 parts water and apply with a pump sprayer to the entire deck. Rinse after 10 minutes thoroughly. This should kill/remove the black spots and not damage the stain.

black mold 2 months after cleaning, brightening, and staining with TWP 1500 !!!!
I properly cleaned, and brightened a new deck that 'cured' for 9 months before prepping and staining. 2 months after properly preparing and staining the deck I have black mold showing up on large portions of the deck. The deck is exposed to a good amount of sun light. I am very upset with this. I spent a lot of money and sweat building this deck a year ago and I was 'anal' about prepping and staining properly. I had debated to use oil based vs. acrylic and went with the 'experts' and used a 'good quality' oil based stain since it was a 'new' deck. What do I do now!!!/???

re: Coverage & shipping
1. 3-5 Gallons for the 2 coats
2. TWP 1500 cannot be shipped to Canada
TheSealerStore , July 20, 2012
Coverage & shipping
550 sq ft of deck boards
Not much railing as I used PVC lattice sheeting Add 100 sq ft to be safe

1) How much TWP 1500 to cover?
2) Cost to ship that amount to Port Hawksbury Nova Scotia Canada?
Doug S , July 19, 2012
re: 1680 sq feet, 10 gallons purchased
No that is probably enough for only 1 coat. You would need another 5 gallon pail for a second coat. If the wood is dry then you should apply a light second coat.
TheSealerStore , July 16, 2012
1680 sq feet, 10 gallons purchased
Hi, I already purchased 10 gallons of TWP1500 (2, 5-gallon units) and have 1680 square feet to cover. Is this enough for 2 coats? Do you advise 2 coats?
Thank you!

Looking for advice if 5 gal is enough to do two coats for a 356 sq ft deck including treatment of the posts/closed steps. I was thinking I would need 6 gallons...

re: deck powerwashed but never sealed
A clear sealer will not prevent UV graying. You must have a tint in the stain if you want it to last.

Best to use a cleaner that is designed for wood and the use of a wood brightener is essential for overall appearance and longevity of the stain. I would look at the Restore-A-Deck for the cleaner and brightener.
Scott Paul - Over 17 Years of Experience , March 15, 2012
I have a 16x32 pressured treated wood deck that is 18 yeas old. Over the years I have had the deck powerwashed but never sealed. The deck has weather to a dark gray color and has mildew stains from overhanging trees. I am currently plan on cleaning the deck with and Oxygen zbleach cleaner and applying a clear sealer. I like what I read about your TWP 1500 series and am wondering if it comes in a clear finish. I live in the Centerville Oh area and would like to know if I can purchase your material in this area. Yhank you for your help!
Larry Anderson , March 15, 2012
re: Deck sealing
Before applying any new stain/sealer you should remove the CWF first. This can typically be done with a stain stripper.

TWP 1500 Series is a great wood preservative and stain and would work very well for you.

Not sure what you mean by "non-stained" look as TWP and any high quality stains are tinted.
TheSealerStore , March 12, 2012
Deck sealing
I have a large treated wood deck. After it was built - about 1.5 years ago - I used Flood CWF-UV deck sealer. It looked good to start, but it already has faded, the decking is cracking and it looks like untreated wood. I assume CWF-UV is water based.
I want a deck sealer that will last for several years and keep the sealed look. Is this the one? Should I pressure wash it before applying TWP 1500? Will it return to a 'non stained looking' look.

re: TWP 1500 stain/sealer
If you have some dark areas it might make sense to use a color that is a little richer like the Pecan.

TWP 1500 stain/sealer
Hello; I have a older pressure treated pine deck that I have just thoroughly pressure washed to get it clean. I would like to seal it now and retain as much of the natural color as possible. It does have some slightly darker shades in some areas. My question is: would I be better to stay with the "Natural:, or go with the "Pecan" to help hide some of the darker areas? Thank You; D Hill

re: home owner
The 1500 Series is a very good stain. Coverage is about 150 square feet per gallon. One 5 gallon should be enough for 700 sq. feet.

Shipping time is dependent on where you live. Typically takes 2-6 business days.
TheSealerStore , May 23, 2011
home owner
I have used TWP in the past and had good luck with it. My deck is old and had to replace some boards. It is open under it. It sounds like the 1500 series would be the product for me. What do you think and how long does it take to get it. I have about 700 sq ft. How much will I need and how long does it take to get it?
