One of the best products I found for water proofing wood. Just amazing. And super easy to apply.

I purchased this product to refinish my small teak table for our patio and two wine barrels I’m restoring. I sanded the old finish for the table with 150 grit paper followed by a finish sanding using 220 grit. I used a small synthetic brush to apply the product. Following the instructions I applied the first coat being careful not to apply too much to avoid ponding. It went on smoothly, I applied a second coat after 15 minutes or so, as instructed on the label. It restored the teak to the original color and beauty. I was able to refinish the top of one of my barrels using the same procedures, except only one sanding with the 150 grit. It turned out great. It was easy to clean the brush as this is a water based product. I found Seal-Once to be a great value for the money. Time will tell how durable it is but I’m confident it will be.

It isn't cheap but far less expensive than rebuilding or repairing my sea side deck. As an 80 year old when I say that it is easy to apply, it must be super easy. The twenty minute drying time between coats is a real boon; by the time you get to the end of the project with the first coat, you can immediately start applying the second without doing a clean-up. The salt ocean air and the rain from the Japanese current are tough on wood so a marine finish is the way to go.

Came a clumpy mess, like it was left out in the winter or was stored incorrectly. Can't even stir it.

Product worked well. I used sprayer on deck boards and then immediately back-brushed the sealer to work it into the very weathered boards of my deck. Surprised by the milky white color of the “clear” sealer I bought, but all the white disappeared within 10 minutes of my brushing. Deck looked wonderfully different when I finished, and sealer clearly worked: water beaded up on boards when it rained a few days later.. Only problem was that one of the upside down cans leaked in the carton despite the metal clasps, making a small mess.
