Q: Is this non-skid?

4 months ago
1 Answer
  • A: It is not non-skid. It is a water proofer that will bead water on top of the wood. Water on top of wood is slippery. Also, you cannot add anti-skid additives to any Seal-Once product. Investigate using 3M no-skid strips. They come in clear and colors.

Purchased last month. Can hardly call it a stain, more like somewhat transparent. Following their directions, WILL NOT flow through a pump up style garden sprayer. Using a longer nap roller to back roller, as recommended, still would not fall between the boards. Will need to go over it with a brush. Slippery when wet, not great for a deck. Application was okay, provider you could back roller immediately. First coat seemed to sucked in immediately, where second coat all but eliminated the woods grain

No, I do not recommend this product.
