9.8 Rating Restore-A-Deck Stain Stripper Booster & Thickening Gel
I would love to hear if you have used the Restore-A-Deck Stain Stripper with the Booster and/or Thickening Gel additives on your wood or deck. Please post a rating in the Consumer Star Ratings below.
If you have any questions as to the effectiveness of your deck or wood stripping project, please ask below with the name of the stain brand and type being removed. Please add a couple of pictures as well.
Note: These are 2 additives for the RAD Stain Stripper. They only work as additives for the Restore-A-Deck Stain stripper and will not work by themselves. This article reviews both additives when used together in the RAD Stripper. We tested this on two extremely hard-to-remove finishes: Behr Acrylic-Based Semi-Transparent Wood Stain and a White Solid Color Deck Stain. Both of these coatings were applied 3 weeks before removal. Pictures of the test boards are below.
Restore-A-Deck Stain Stripper Booster – Up to 300% More Effective

The Restore-A-Deck Stripper Booster will increase the effectiveness of stain stripping by up to 300% by helping to break down the surface tension of difficult-to-remove wood stain finishes.

Restore-A-Deck Stripper Thickening Gel Additive – Clings up to 1 Hour

With a longer dwell time, Restore-A-Deck Stripper Thickening Gel will increase the effectiveness of stain stripping by adding the ability to cling to vertical and horizontal surfaces for up to 1 hour. Works especially well on improving the stripping performance on vertical wood, such as wood railings, wood fences, and wood-sided homes.
