Seal-Once Marine Premium Wood Sealer - Waterproof Sealant - Wood Stain and Sealer in One - 1 Gallon & Clear

Im in central FL and had this playhouse in the elements for maybe 1 week with heavy rain twice. After leaving it to dry it really dried out the cedar. Always kept it covered and only 6 months old. Glad I sealed it because it did not come sealed. This was easy to use and not messy. A little runny but worked well with a regular brush. Was able to get 2 coats on quickly since it dried fast. Dried very smooth, no problems with bubbling unless I was trying to get in the small spots and they would brush right off after a few minutes. Finish is smooth, hope this lasts. Great price and value compared to others.

For a water based sealer this is really interesting. I bought two gallons and covered both sides of decking for a 14x10 deck. Hardly put a dent in the first can. Looks promising but time will tell

First photo is the applied product . Second photo is applied on the right side, but I haven’t gotten to the left side yet. On the applied pickets, this morning, the day after applying , it’s still feels like raw wood to the touch. Which I’m happy about , it seems like the first round soaked into the wood, but did not give it a high gloss feel .I’m using it on my back fence. Clear, first off. It’s like any other can of paint, if you open it and go straight to application without stirring it well of course it’s going to be chunky. If you shake it, yeah it’s gonna foam up. You need to stir it very well, scrape the edges. I used an extra long kitchen whisk actually, I find it mixes so much easier but a paint stick is just fine. Do it thoroughly. I dry brushed really well then power washed it and let it dry for a few days. I used a corded paint sprayer on low output, stayed the same speed and distance away, did 2-3 boards at a time, and then went over them immediately with a paint brush to really spread it out. My wood was very raw and damaged from the sun and moisture so it absorbed VERY quickly which is why I sprayed just a few at a time and went over it quickly with a paint brush to push it in and around before it soaked up. It soaked in FAST. Some I had to spray over thickly a few times because they were so sun damaged and dry and soaked it up. But it took to the wood with careful application. I got about 25 feet of 6 foot standard picket fencing done with one gallon. We get the Marin layer in the mornings here so I did it in the afternoon when the fence was very dry and still had time to try again after applying it.

I was hesitant about ordering this based on other reviews. Product came well packaged. It mixed no problem. I am refinishing my dock. It has never been coated and is made of cedar. I stripped the gray with 50 grit belt sander. Then these photos before and after with 2nd coat applied. It was much easier to apply with an exterior stain pad then a brush and saved alot of time using that method. Keep a brush handy though to smooth out. Not sure why the colour tints are not available here but would have loved to get the cedar color.

I am returning to leave this review having 3 years of experience with this product. I purchased Seal-Once Marine Penetrating Wood Sealer (clear) in June 2023, 3 years ago, and applied it to a large gazebo (from Costco) on my deck. Seal-Once has done a phenomenal job of protecting the wood, and the gazebo still looks almost new. My experience with prior brands of sealer/waterproofing caused me to do a lot of research while selecting which protection to use on my new gazebo. I live in sunny California so sun damage was my primary concern, but we average 54” of rain annually so I was also looking for water protection too. I have been pleasantly surprised that this product has really surpassed my expectations. I am a very satisfied customer and will continue to use Seal-Once Marine Penetrating Wood Sealer. (The attached photo was taken right after the gazebo was first installed.)
