Important Note: This is our 2nd Review of TWP 1500 Series. Our first review of the TWP 1500 Stain was started in 2010 and completed in 2012.
See Here for First Review: TWP 1500 Series Review
*Note: TWP 1500 and the TWP 100 are the only deck stains registered by the EPA as a wood preservative. The 1500 is compliant in all US states while the 100 Series is not.
TWP 1500 Stain Deck Stain Scores (1-10)
Appearance After Initial Stain Application: 8.5
For the pine deck we used the TWP 1530 Natural. This is not a “clear” but rather a traditional cedar color in our opinion. The manufacturer stated they made this color in the 1500 Series to match the color of the TWP 101 Cedartone. This allows for an easy switch from the 100 Series for consumers who are in a low voc state.
The wood grain was highlighted naturally with the 1530 Natural semi-transparent tint. The 1500 does not mask or film on top of the wood grain.
Preventing UV Graying at 2 Year Mark: 8.5
Excellent at preventing UV graying at the two year mark. For the vertical railings, the TWP 1500 lost very little of the color. For the horizontals, we saw close to 80% color retention.
Same results as last time and one of the better products for preventing color fading
Wear/Tear and Peeling: 8
The TWP 1500 penetrates deep into the wood reducing the chance of wearing. We find that the 1500 Scored well here for a low VOC oil based stain.
Note that when staining brand new wood with TWP, we have found that it is best to let the wood season in the elements for at least 3+ months. Once it is weathered, we prep with a deck cleaner and wood brightener to enhance the stain penetration. Only 1 coat of the TWP 1500 for new smooth wood.
