TWP 1500 Series Stain Review4.5/5(2)

TWP 1500 Series Deck Stain

TWP 1500 Series Deck Stain

TWP 1500 Series was introduced in the Summer of 2010 as the replacement for the TWP 500 Series. TWP 1500 stain is a semi-transparent oil based wood preservative registered by the EPA. The only deck preservative that is currently registered as an exterior wood preservative.

TWP 1500 Series is designed for all exterior unfinished wood. It has excellent UV resistance from graying. It is mostly used for exterior wood decking, wood fencing, log homes, cedar sided homes, etc. TWP 1500 comes in 10 colors that allow the natural grain of the wood to show through.

TWP 1500 Series Deck Stain Scores (1-10)

Appearance After Initial Stain Application: 8.5

- TWP 1500 Series had a beautiful rich look to the wood. Wood grain was highlighted naturally. 1501 Cedartone color was slightly brown for a traditional cedar color.

Preventing UV Graying at 2 Year Mark: 9

- Excellent at preventing uv graying at the two year mark. One of the top stains that we have tested in terms of absorbing the UV radiation that causes oxidation of the wood.

Wear/Tear and Peeling: 9

- Very good at preventing peeling. TWP penetrates deep into the wood. This seems to reduce any chance of wearing or peeling at the surface.

Cost Per Square Foot: 8

- TWP 1500 Series cost us $174.99 for a 5 gallon pail delivered. This breaks down to $.35 per foot for 2 coats of stain on our 400 square foot deck. We still had 1.5 gallons left when done. Coverage for the TWP 1500 was close to 200 square feet per gallon.

Preventing Mold/Mildew/Algae: 9

- Of all of the oil based stains we tested, TWP offers the best protection against mold spores that are known to grow in oil based stains. This is most likely due to the oils used in TWP’s stains. They do not use linseed oil but rather a mixture of natural and synthetic oils.

Ease of Application: 8

- For an oil based stain, TWP 1500 series applied well. We did notice that you need to back brush any puddles to ensure an even application. This is normal for most of the stains that we have tested. TWP 1500 Series did dry to the touch in 6 hours and we were able to put furniture back on the deck the following day.

Color Shifting (darkening) after 2 Years: 9

- The 1500 series did not “darken” in color like other oil based stains have been known to. TWP actually lightened up slightly at the 2 year mark. This gave the wood a more natural looking feel.

Difficulty of Reapplication: 8.5

- TWP 1500 Series would be an easy stain to reapply. A normal wood deck cleaner would be used to remove some dirt and grime, prepping for another coat.

Overall Score TWP 1500 Series at 2 Year Period: 8.5

- TWP 1500 Series (and 100 Series) have been known to provide tops in terms of durability and color retention. They have always been one of the best stains and is one of our top choices. Little to no fading on the railings. The deck surface faded to about 75% of the stain’ initial color after 2.5 years.

    We are having a 12 x 16 deck built using Cedar. We are in Northern Ohio and the beginning of winter starting soon. We are wondering whether we should seal the deck now or wait until Spring. Warmer sunny days are a rarity now rather than the norm. Will it hurt any if we do decide to wait until Spring to do this? I hate the thought of trapping moisture into the wood right now by sealing it.

  2. Lisa, clean and prep with the Gemini Restore Kit. We do not have much experience with the 200 series so I am not sure what color would be a match. I would call the manufacturer for some help with this.

  3. Denis, TWP 1500 is not able to be used in Canada. This came from the manufacturer. I would consider the Armstrong Clark if you are able to get it.
