SEAL-ONCE MARINE Wood Sealer, Waterproofer & Stain - 1 Gallon Penetrating Formula

ErikaErika: This stain is a game-changer for dock protection. I applied two coats of this sealer/stain which left my cedar dock not only waterproof but also enhanced with a beautiful bronze color. I used a brush for application which was a breeze, and the quick drying time was a plus. Exceptionally water resistant which is crucial for a dock constantly exposed to the elements. The color retention is impressive, maintaining vibrancy even after sun exposure. What sets this wood sealer and stain apart is the fact that it is safe for use over open water and non-hazardous to aquatic life. It's a reliable investment for lasting results. A+++!

Dana Head: I used this product on my wooden deck it was easy to apply with the brushes I also ordered. I purchased the natural stain and it made the wood change slightly. It was easy to install the second coat. I cleaned the brushes with soap and water. After it rained on deck the water beaded up. I am waiting to see how it holds up during the winter months. I am very pleased so far.

Mike: I used the 1 gallon clear version of this product on the Wood Bed of My Trailer and on a 50' Section of Snow Fence. From what I've seen over the last 2 months the product has certainly helped the water-proofing of my Trailer Bed, and I'll have to see how it does on the snow fence in the late Spring. But the product was very easy to work with, to include in my paint sprayer where I was able to pour it directly into the sprayer bottle w/o diluting it. Cleanup was a breeze with water & a little dish soap spraying out of the sprayer.

Amazon Customer: Product goes on easily, quite runny in order to penetrate wood. Highly advise using a cleaner prior to use. Very good results and lasts.

Mario: I followed the directions with preparation and application. It looks amazing and you can see water beading as it should. I used the clear and the cedar looks amazing.

CTCT: Used this for all of the sub-floor and framing on my boat (Mahogany, Cedar and Marine Grade Plywood) this was fairly easy to work with (almost like brushing on milk). You will definitely want a good quality synthetic brush which will hold this in during application, as again, it's like trying to paint with milk. 15-20 Mins between coats as stated on the can for 3 coats, and the results are fantastic. Very Impressed. I am glad I forked out the extra money for this product as compared to other wood sealers/epoxies/coatings. This was recommended to me by a marine shop, and I would have to agree. I highly reccomend it now too.

SandraSandra: This product goes on quickly, with no odor. I applied it on a 20ftx30 deck and it took 1 gallon. When you apply it it looks milky but dries clear. The manufacturer specifies very quick 2nd application- which is handy because you’ve got everything clear including animals.
It has rained all summer and the sealer has repelled water marvelously. #winner

Wayne Linehan: Although product was good we are still getting a Fedex bill for $67.32 from fedex
Shipping from Amazon was free. We phoned Amazon weeks ago and they said they would take care of it.

BtompkinsBtompkins: UODATE: We give the product 4 stars so far. It looks wonderful and goes on easily. I’ll update the durability once it’s been on for awhile and hopefully give the sealer 5 stars.

We give 1 star to the seller. The actual seal once company (not the seller here on Amazon) went above and beyond to answer my questions. The clear that was sent was tinted with bronze cedar. Clear is supposed to be clear. How the seller got things so mixed up is a mystery.

FIRST POST: We received our order of 2 gallons BUT the clear isn’t clear and the other can is labeled bronze cedar!! We started using the second can before we noticed the different label. The old deck is done but now the first half is not the same tone as the other half. Does the clear have a color? Ours does. Want to do our stairs but not sure which to order for another gallon. Help!!

Mike C.Mike C.: The wood on my dock is about 9 years old. In south Fla the wood gets beaten on by the sun pretty much all year. The wood was faded and beginning to splinter. With wood prices through the roof right now I wanted to try and save it. I pressure washed it - yes, frowned upon, I know. I needed to get the mildew out of the cracks and crevices. I then waited two days and used my Greco air sprayer to apply it.

It went on super easy. I followed the directions and applied two coats fairly close to one another. I have 750 sq ft of dock and used 4.5 gallons. I'm very impressed with the look. I originally thought Clear would leave it looking faded so I got some of Seal-Once's light brown color, but it looked artificial to me. The Clear brought back the younger look of the wood as can be seen in the before/ after pictures. The after picture is after a recent sun shower. The water beads nicely (applied early April) and the color looks the same wet or dry.

I cannot comment on longevity yet but I'll give 5 stars now and update as needed.
