Seal-Once Nano Penetrating Wood Sealer - Premium Waterproof Sealant - 1 Gallon Clear Wood Sealant

Good product. Good value. Seems like an excellent alternative to toxic pressure treated lumber — which most lumber yards even refuse to cut for customers.I don’t have 10 years to test this stuff, but appreciate that it goes on easy, doesn’t smell and is easy to clean up.

Good product

I was expecting something more the consistency of paint or some other wood finish, but this has the same viscosity as water. So it was a little sloppy to apply.It also doesn't really do anything to bring the wood to life. I used it on Doug Fir, and it looks very flat with none of the 'glow' you would expect to see on something that had just been refinished.On the plus side, it has stood up over the winter and the wood still looks good. It seems to have done a good job of waterproofing.

Invisible when dry, and completely waterproofed my outdoor stuff with one application. For small items, I simply dipped them in the bucket and hung them up to dry. The product looks like watery milk, so it's kind of messy, but it easily washes off your hands with soap and water, and it didn't appear to hurt the grass at all when I used it in the yard. This gallon will go FAR, and protect my things for a long time.

I used the product on some decking that needed treatment before I installed it. I didn't write a review immediately after buying because I wanted to see how effective it is. I'm not big on writing reviews of the pretty packaging or the sales experience. It's certainly easy to use and seems to be doing a good job of protecting the wood even after some pretty heavy rain. I only gave it a 4 for longevity because I cannot possibly provide proof! Ask me again in 10 years' time.

Product was not sealed and spilled all over inside and outside of the box.

July of 2023. The deck wood is pressure treated and it has been on the deck for two years and it was untreated or sealed prior to applying Seal Once. I pressure washed my deck. I allowed the deck to dry for two rain-free days. The product went on easily (horizontally on walking boards & steps) with two coats applied and a roller used. After two weeks, I am not impressed with the level beading after a rain. However, next summer I will report if it still beads up water after a rain and to what extent. We will see.

This sealant goes on very easily. Love the finished effect it had on my outside garden chairs.It is water resistant and great value for money.This sealant protects from the rain and water and has a sheen effect.
