TWP 100 Series Wood Deck Stain Scores (1-10)
Appearance After Initial Stain Application: 8.5
- We tested the 101 Cedartone color for the pool deck. The semi-transparent color was a traditional cedar color, slightly orange/yellow. The stain had no issues penetrating into the wood completely and did not mask the wood grain.
Preventing UV Graying at 2 Year Mark: 8
- The TWP 100 Stain retained 80% of the original color after 2 years of weathering.
Wear/Tear and Peeling: 8.5
- TWP 100 exhibited zero peeling of the stain after 2 years. Slight wearing around the stairs where the wood butted up to the pool. This area was slightly more faded as well. Possibly from the chlorine in the pool.
Cost Per Square Foot: 9
- We paid $139.99 for the 5 gallon pail of TWP 101 Stain. We used all 5 gallons for the 800 foot pool deck. We applied two coats to the wood. Cost to stain with TWP 100 Series was $.18 per foot for 2 coats of stain.
Preventing Mold/Mildew/Algae: 10
- TWP offers the best resistance to mold and mildew for an oil-based wood preservative. No mold, mildew or algae spores were present on the wood decking.
Ease of Application: 8.5
- TWP is easily applied. We applied two coats to the flooring using a 18″ wide stain applicator. The first coat took us about 30 minutes to cover 800 feet. Second coat took only 20 minutes as the TWP 100 applied at a better spread rate. Overall the 800 square feet was covered in under an hour and applied evenly with no puddling.
Color Shifting (darkening) after 2 Years: 9
- TWP 100 lightens in color after 2 years. No darkening from UV or mold.
Difficulty of Reapplication: 9
- TWP 100 Series offers deep penetration with no darkening of the stain. Reapplication will be easy without the need for stripping off the two year old stain. Cleaning to remove some dirt and grime would be enough to prep for another coat.
Overall Score TWP 100 Series at 2 Year Period: 8.81
- TWP for good reason gets one of our top overall scores. It is too bad that this product is not available in all 50 states but the TWP 1500 Series performed nearly the same in our test results and can be obtained in all states. If you are looking for a great stain that is economical as well, then the TWP 100 Series should be considered.
