Q: Is this non-skid?

3 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.

Average at best

23 days ago
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.

Brings life back to old, grey wood

a month ago
I wish I would have taken before pics! This deck was grey and ugly! I applied the suggested cleaner, power washed it and sanded a few spots. I had to fill a few cracked spots that are visible after painting. It was relatively easy to apply, however there are some lap marks where I painted under the railings prior to painting the floor boards. It’s not very forgiving with drips, either. Not a big deal for me at all and overall very pleased with the finished product! It brought life back to my old, grey deck! Hoping it lasts as long as it says it does! Color is light brown.

Yes, I recommend this product.

Very good product for wood

a month ago
The wood finish applies smoothly and evenly, allowing for excellent coverage with minimal effort. It’s consistently is easy to work with helping the brush glide across the wood surface without leaving noticeable streaks or brush marks.

Revitalized an old picnic table

a month ago
Really soaked into the wood, as i was hoping. No fear of a peeling coating. After a sanding and a couple brush coats of this product, the table looks nearly new again.

Yes, I recommend this product.
