TWP 1500 Deck Stain Rating
TWP 1500 Series Deck Stain Scores (1-10)
Appearance After Initial Stain Application: 8
– The appearance of TWP 1500 Wood Stain on our test deck was a warm rich finish. The wood grain was enhanced and highlighted effortlessly. The 1501 Cedartone color was a little browner (not as orange) than a conventional cedar stain color.
Preventing UV Graying at 2 Year Mark: 9
– At the 2-year mark, TWP was holding up well against UV graying. This was one of the top deck stains tested as far as reflecting UV radiation that typically creates wood fading and discoloring issues. TWP 1500 retained about 80% of its initial color at 1 year and 70% at 2 years.
Wear/Tear and Peeling: 9
– TWP 1500 displayed zero signs of peeling and only a slight amount of wear. TWP is not film forming. The stain dives deep into the wood fibers, which reduces any chance or wearing or peeling on the wood surface.
Cost Per Square Foot: 8.5
– TWP 1500 Wood and Deck Stain cost us $39 per gallon. We applied 2 coats “wet on wet” to our 400 square foot test deck. Coverage for the TWP 1500 was 125 square feet per gallon for 2 coats applied wet on wet. The cost broke down per square foot was .35 cents.
Preventing Mold/Mildew/Algae: 9
– In our testing of oil based deck stains, TWP 1500 offered one of the best resistances to mold spores and fungal growth, which some oil-based stains are known to attract. This was most likely due to the EPA registered mildewcides in the TWP formula. Also contributing to the lack of spores is the use of synthetic and natural oils and a limited amount of linseed oil, which has been known to promote mildew growth.
Ease of Application: 8
– TWP 1500 Wood and Deck Stain applied fairly well for an oil-based formula. It was necessary to back brush or wipe excess stain to get a nice even finish. TWP 1500 Series Stain dried within 6 hours and we were able to place items back on the deck.
Color Shifting (darkening) after 2 Years: 9
–At the 2-year inspection, no noticeable darkening was apparent like we have seen with other oil stains. The 1501 Cedartone color essentially lightened up a bit giving a more natural appearance.
Difficulty of Reapplication: 8.5
– We are confident that the TWP 1500 Wood Stain would be easy to recoat. A quality deck cleaner could be used to remove common dirt and grime prior to re-staining with TWP 1500 again.
Overall Score TWP 1500 Series at 2 Year Period: 8.5
– The TWP products like 1500 and 100 Series Stains are known to produce a durable long lasting finish. They have always been a favorite of ours and are consistently one of our top choice stains. We personally use the TWP stains on 300+ deck restorations annually. Ease of application, a beautiful finish, and easy recoating makes TWP 1500 an outstanding professional grade stain for all exterior wood projects.
