TWP Deck Stains – Semi-Solid Pro-Series Review
TWP Semi-Solid Pro-Series Wood Deck Stain Scores (1-10)
Appearance After Initial Stain Application: 9
– We prepped the deck first with the Restore-A-Deck Stripper and Brightener kit and applied the TWP Semi-Solid in the Cedar Mulch color after a few days of drying. The overall appearance was excellent with very even coverage. Semi-solid in appearance with a small amount of wood grain showing. The TWP Cedar Mulch color penetrated deep into the wood grain on our pressure treated deck. This will result in little to no wearing and peeling down the road. We would expect this stain to last 2-4 years before a reapplication is needed.
Preventing UV Graying at 2 Year Mark: N/A
– This is a brand new stain from TWP. The base of this stain is the TWP 100 Pro-Series and which has consistently scored an 8 out of 10 at the 2-year mark. We expect even better UV protection due to the higher solid content of the semi-solid. We will update as needed.
Wear/Tear and Peeling: N/A
– TWP penetrates very well into the wood grain and this is normal. The TWP 100 Pro- Series (base of the TWP Semi-Solid) scores a 9 out of 10. We expect the same results for the TWP Semi-Solid Pro-Series.
Cost Per Square Foot: 8
– The price paid was $250 for the 5-gallon pail of TWP Semi-Solid Pro-Series with Free Shipping. The coverage rate is excellent for the TWP Semi-Solid and we used less than 4 gallons for our 800 sq. foot deck. The total amount for the stain on our deck came to $200 or .25 cents per square foot.
Preventing Mold/Mildew/Algae: N/A
– The TWP 100 Pro- Series (base of the TWP Semi-Solid) scores a 9 out of 10. We expect the same results for the TWP Semi-Solid Pro-Series when preventing mold or mildew.
Ease of Application: 9
– Before starting your deck staining make sure to blow off any debris from the deck such as leaves and dirt. Prior to applying any stain, you need to thoroughly mix it evenly. We had no issues mixing the TWP Semi-Solid to a smooth consistency. We applied only 1 coat to our deck using a deck stain pad applicator to ensure an even appearance. Overall, we applied the TWP Semi-Solid stain in 1-2 hours to the 800 sq. foot deck and a team of two employees.
Color Shifting (darkening) after 2 Years: N/A
– The TWP 100 Pro- Series (base of the TWP Semi-Solid) scores a 9 out of 10. We expect the same results for the TWP Semi-Solid Pro-Series when it comes to preventing darkening.
Difficulty of Reapplication: 8
– Reapplication in 2-4 years will be as easy as using their Gemini Restore A Deck Kit. One of the kits will be enough to clean and brighten the deck for reapplication and then apply 1 maintenance coat of the TWP Semi-Solid Stain
Overall Score TWP Semi-Solid Pro-Series Stain: 8.5
– The TWP Brand of Stains is one of our most commonly used wood stains as we have personally applied it to over 10,000 decks over the past 25+ years as wood restoration contractors. What we like best about the TWP Semi-Solid Stain is that it is easy to apply, will be easy to prep and reapply when the time comes, and holds color very well from the UV. We are very excited and look forward to using the TWP Semi-Solid colors. Maximum UV protection and a much larger color palette is the top reason we will be offering the TWP Semi-Solid to all of our customers in 2021 and beyond.
Note: We do not use TWP on brand new wood. If applied to wood that is less than 4 months old, it seems to have a difficult time with penetration. We find this with many of the stains we have used on new wood. The manufacturer suggests waiting 4-12 months to let the wood weather. We strongly suggest that you wait and only apply one coat for wood that is 4-12 months old.
