Seal-Once Nano+Poly Penetrating Wood Sealer with Polyurethane - Premium Waterproof Sealant -1 Gallon & Clear

Great stuff! Applied to our bare pine ranch table and benches. It goes a long way and the finish is nice, showing the wood grain and color, though slightly milky. You wouldn't know it if I didn't tell you. I light sanded the wood, vacuumed and wiped down with a wet tack cloth. The sealant goes on easily with a brush and a little goes a long way. Didn't use 1/2 gallon to cover a 120" x 40' table and two 108" x 16" benches, top, bottom and legs with two coats! It did require two people to get the second coat down (instructions said to apply second coat when first is damp), as in the Arizona heat, it was drying pretty fast. The ranch table is out on the covered patio and now I can wipe the dust off in minutes. I'm very please with this product.

The product was easy to apply, but one needs to be very aware of the 20-30 minute time between first and second coats. Break the deck area down into smaller sections the size that you can apply the first coat in the time period but an area that you will be able to fully reach in order to apply the second coat. I used a brush which allowed me to really work the product in real well to obtain the best penetration on the first coat. My deck is Western Red Cedar which is a very porous and absorbs well so I needed to make sure to apply enough on the first coat to ensure a full penetration seal. The next most critical thing is to keep the leading edge of your application live or you will get a line between the the application stages. I live in the interior of British Columbia in Canada. Winters are long, wet, snowy and cold. Summers are hot and dry. All products that I have used in the past never make it through a single season. I apply them in May - June and they are gone by the end of December. I always have to fully sand and refinish every spring. Claims for Seal-Once Nano + Poly suggest I should get multiple years of use with out refinishing. Only time will tell. I am very hopeful but the jury is still out, as I only just finished the sealing.

Seal once brushes on easy and does not change color of wood. What is most satisfying is that when it rains you can see the water just laying on the surface as it will not penetrate wood.

Seems to be good. Time will tell. Ordered twice and the wrong color was sent first time but no biggy. Returned it fine and got it right second time. Application was fairly easy and straightforward. Had just enough to brush on 2 coats within an hour of each other. My deck had to be sanded down to bare wood before applying it but will see how durable it is over the next year or so.

Don’t buy it. When you apply it, works perfect and you have the water beads coming off the deck! Coming out of the winter, water just soaks right through and the coating didn’t even last one winter! Followed the instructions perfectly as well!
