SEAL-ONCE Marine Penetrating Wood Sealer and Waterproofer, Clear, 1 Gallon

Honestly, I didn’t know what to think. There are several negative reviews, several positive, which left me in a bit of a lurch. Do I risk it and potentially regret it, or will I be a lucky one? I went ahead and pulled the trigger and couldn’t be happier. I followed the directions to a “T”, bought the clear and then purchased the black tint separately. This stuff goes on like a dream. It’s is a bit watery, which the green painting tape didn’t completely guard against, but being water based made for pretty easy cleanup. I’ll try the upgraded paint block tape next time. We’ve had a hard rain today and this stuff had performed flawlessly. Water beads up and runs right off, the wood fibers seem very well protected/sealed, nothing to complain about as far as adhesion goes. Time will tell if it lives up to its stated duration. Honestly though, it goes on so easy and looks so good, I’m not opposed to having to reapply earlier if needed.

Good product, easy to apply and can recoat almost immediately- save lots of time

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.)

Great product will order again

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.
