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

Good product

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 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.

Bought this a few times now and added the Brown stain to it. What a beautiful color, first off. The water repellent is great on the Nano. Instructions say to apply a second coat within thirty minutes because it beads up water after that. I've used it on my deck and my new blueberry cage that I'm currently building during the COVID19 mandatory shelter in place order. It's a great product, and I'll continue using it my future projects. It's a very watery product, so be careful not to waste it when applying it. We used a brush rather than a sprayer so we could stretch it out. You don't need much on the paintbrush - just a few dabs on the tip and then start blending it in. If it starts to drip on the wood, you can simply take the damp brush and go over it again to smooth it out. It's very easy to work with. Of note: it is white if you don't color it and greyish if you do, but that is not the color it dries.

I was expecting this to dry to a shine but it dries flat. Also it does not hold up to sun drenched areas. I just applied this to my cedar trim in May and I am having to redo it already because it looks terrible. Would not recommend.

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.

Been building and installing outdoor structures for over 25 years. Normally used treated lumber or natural cedar which I sand smooth and router a smooth edge on to avoid splinters. Normally encourage customer to accept natural weathered color but thought I would try something different. Bought this product to seal cedar beams on an fully exposed outdoor shade structure and two vertical posts that are under roof. Product lasted about 1 year with noted fading and loss of protection within 6 months. Used untinted version on exterior structure - full failure on horizontal and vertical members exposed to direct sunlight. Now the structure is mostly an "ashy" grey color like cedar normally fades to with exposure - NOT the rich vibrant natural wood that it started out as. I followed all instructions fully, applied two coats to parts in a covered building and then assembled on site. I added "cedar color" to vertical posts and they initally looked amazing but portions of post exposed to sunlight have faded to same grey color as other structure. Sanded down a second time, washed clean and vacuumed for reapplication - product is already fading after 4 months. I would consider this an INDOOR PRODUCT ONLY! It has not met the hype or justified it's costs and application of effort. This is nothing special.
