TWP 100 “Total Wood Preservative” Deck Stain protects and maintains all exterior wooden surfaces. TWP Wood Stain is a special blend of chemicals in a contractor grade formula that safeguards and protects exterior wooden surfaces.
TWP® 100 SERIES penetrates deeply into wood without excessive surface film build, highlighting existing grain patterns with amazing clarity and warmth and is specifically designed to provide protection against the four major causes of wood degradation: wood rot, water, sunlight & mildew.
TWP Exterior Wood Preservatives are the only wood and deck stains on the market that are registered as exterior wood preservatives by the EPA.
TWP 100 Series Wood Deck Stain Scores (1-10)
Appearance After Initial Stain Application: 9
– We prepped the deck first with the Gemini Restore Kit and applied the TWP 120 Pecan color after a few days of drying. This deck was originally done with the TWP 101 Cedartone. The customer wanted to use the Pecan this time as it has a slight “brown” tone. The overall appearance was excellent.
Preventing UV Graying at 2 Year Mark: 8
– Same as the first time tested, The TWP Pecan 120 retained about 80% of the original color after 2 years of full exposure to the elements.
Wear/Tear and Peeling: 9
– Very minor or no wearing of the TWP. TWP penetrates very well into the wood grain so this is normal and expected.
Cost Per Square Foot: 8
– The price paid was $170 for the 5 gallon pail of TWP 101 Stain. We used 6-7 gallons for our 700 sq. foot deck. Total amount for the stain cam to $240 or .35 cents per foot.
Preventing Mold/Mildew/Algae: 9
– No mold or mildew. Some green algae along the edge, near the home.
Ease of Application: 9
– We use the suggested TWP application of “wet on wet”. Pump sprayed on the first coat for the floor very lightly and applied the second coat with a pad applicator to ensure an even appearance. Railings were stained with a pad and brush. Overall, we applied the TWP stain in a few hours to the 700 sq. foot deck and a team of two employees.
Color Shifting (darkening) after 2 Years: 9
– The TWP did not darken from mold or UV discoloration.
Difficulty of Reapplication: 8
– Reapplication 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. No stain stripper will be needed to remove as the TWP has faded lightly and evenly over the last few years.
Overall Score TWP 100 Series Stain at 2 Year Period: 8.5
– Once again the TWP is one of our most commonly used stains. We personally have applied the TWP 100 Series to many 100’s of decks and rarely have an issue. Easy to apply and easy to reapply when the time comes. There are a few other stains that are as good, but as of yet, no other product has been better.
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.
