Rated 4.8 out of 5 by 5 reviewers.
Rated 5.0 out of 5.0 by Great color, easy to use waterproofing! This semi-transparent waterproofing stain is very easy to use and has soap /water cleanup. It is a bit thicker than I had expected (kind of like a pancake batter) and looks opaque until it dries. The thickness makes it easier to use with less dripping and mess than other waterproofers. The only mess I had was with trying to pour from the can (a longer pour spout would have been nice.) I tested it on some pressure treated wood, and after sanding it, the stain absorbed well into the wood. The maple brown color is a little lighter than it appears in the chart, but it looks good. I need to add a shelf on my cedar arbor to install lights on it, and this shade will match great! It does repel water well, as the beading shows in the photo. I do like that this can be applied on damp wood as well, since we seem to getting so much rain these days that wood hardly gets a chance to dry thoroughly. Although I enjoy staining with a water cleanup product, I don't like the idea that I can't store it in my garage during winter months like I could with my older oil version stains. June 17, 2014
Rated 5.0 out of 5.0 by Very easy to apply, dries fast Like that this is more of a thin paste than just a liquid, it makes it very easy to apply with a brush. We applied it to brand new pressure treated wood on a trailer deck, and it looks great. I did two boards at a time and don't see any brush marks. Not sure how long it will last on a trailer but says 4 yrs on a deck so will probably depend on how hard we use the trailer. You can see a little of the green on the pressure treated wood since this is a semi transparent. I also did a regular 2x4 piece to see the color difference and it wasn't very different, just a bit lighter on the untreated wood. Overall very pleased with the end product. Love the easy water cleanup. July 25, 2014
Rated 5.0 out of 5.0 by Great product. Great product. It's a lot thicker than Thompson's Water Seal. We live on the coast so our decks go through a lot of abuse. The semi-transparent covers well and dries quickly. We used a combination of garden sprayer and roller to apply the stain to our dock. It's a little too thick for a basic garden sprayer cause it would clog the nozzle but since it is so thick the sprayer helped us get in between the cracks of our deck. It cleans up with soap and water. The color has more of an orange tint than I expected. I would have liked more brown but other than that I'm happy. September 2, 2014
Rated 4.0 out of 5.0 by Please develop a new color line. This stuff is fantastic. I power washed my deck and let it dry. I painted just the stairs to try it out for color and coverability. It completely recolored the stairs and after the first rain, proved how it does waterproof the wood. The down side is the color choices. The maple brown I used was very orangish and my son and granddaughters said it looked like vomit. I tried to power wash the stain off to restain a different color and this stuff is impenetrable. Great stuff except for the color. June 21, 2014
Rated 5.0 out of 5.0 by Great product This product is easy to go on, but be careful to go with the grain of the wood as it doesn't wipe off once it dries. I played around with it on scraps before applying and discovered this. Dries quickly. June 26, 2014
