Great Stuff
Put one coat on some cedar fence last year. Noticed the other day how good it still looks. Went and coated it again and the product beaded up just like it was applied yesterday. Excellent outdoor sealer. This penetrates and makes water bead up but does not leave much of a surface film. Its super easy to apply and totally forgiving.

This is what you need!
Wow! I couldn’t be more impressed! I searched for the perfect sealer for a live edge outdoor art piece and this one ticked all the boxes: Goes on quick and easy, low/no odor, soap & water clean up, fast drying, non-yellowing and excellent waterproofing. The best part!? It lived up to all of my expectations! The only “negative” about this product (which was actually an amazing bonus) was the clip added to the top of the gallon to prevent leaking during shipping was on tight and took some muscle to remove!! Shipping was lightening fast too!! It did an excellent job in sealing the live edge of the wood and I anticipate it will preserve it for years!

Water beads up, consistent coverage, good stuff
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.

Effective Sealer
Great water sealer but white of paint shows through on deck when wet and deck surface is a bit sticky on hot days. However product repels water and takes a while for it to dry.

READ and following the instructions
All of my reviews are of things I buy for myself. I do not accept freebies or anything in exchange for my reviews. Period. The Marine stain-sealer works very good. It has good coverage, goes on easily and quickly and the result is long lasting and looks great. It's my go-to stain-sealer now. I use it on my decks instead of the nano type. I've read many of the reviews and throughout many of them the same theme comes up, lack of proper wood prep or not following instructions. Preoprly prepared wood and follwing instruction will provide you with one of the best stain and sealer applications of any product including the top tier name brands. The wood. If the wood isn't properly prepared then no matter what you put on it will fail prematurely. Putting any stain and selaer on new bought wood is a mistake unless you first clean it and sand it. The wood you buy often has a waxy coating on it and sometimes anti-mold agents put on it. If all you try to do is buy new wood for your deck or project and then just stain and seal it, it won't last. Clean the new wood first, it's easy and you can use a dilution of bleach, water and dawn dish soap. Use a deck brush to scrub the wood and then rinse it off real good. The let it dry for at least two days, 3 or 4 days if it's humid or not really warm outside. If you don't do this the stain and sealer will not take. Before you apply the stain-sealer, test for penetration. When you apply a small amount it should soak right into the wood. If it sits on top, it's not going to work, nothing else will either. If you are using it on a deck, sand it even after cleaning the boards. Then just before you sapply, wipe the boards with a damp clean rag. Do not rely on using an air compressor or brush to get the sanding dust off. The rag should be just damp, not soaking. Let the boards dry for a few minutes and then apply the stain-sealer. It should soak right into to wood. This coat should not be heavy, but rather a light to medium light coart. You should not see shine on the surface. If you do, that means the stain-sealer isn't penetrating and you didn't prepare the wood correctly. On a 16' typical deck board, start from one end and let it sit for about 5-10 minutes. Go back to where you started to put on the secnd coat. This will be a light coat and it might seem shiny for just a short time. Don't use a heavy coat or it will sit on top and come off ahwn it wears or water gets on it. Curing. Let it cure. 2 days is best. Planning for this time is essential. If you need to use the deck then do part of it and then block that area off. Rotate areas you can use vs areas that need to cure. When to apply. After the morning sun is up and temps are up. Applying stain-sealer while the air has a lot of humidity is bad practice. Same with trying to finish some boards late in the afternoon unless your area is still nice and warm with low humidity. Decks or docks near or over water. The air is full of humidity so only aply at the height of the warm part of the day. Many boards on docks have been previous treated with oily sealers. Sorry, you'll never get that stuff off the boards so your choice is to use a similar sealer because nothing else will hold up. So clean your dock boards really good. The problem is that anything you use to clean much be ok if it gets into the water or can drain into the water. That means if the wood was treated with any oily type selaer nothing you can use that is safe for the water will also take off the previous oily sealer. Use the right product for the job. Brushes. Amazingly, some of the cheap synthetic brushed worked far better than expensive name brand brushes. The more expensive brush load up too much sealer and that isn't what you want. You want the sealer to run off and out of the brush so you can control how much goes on the wood. Trying to spread the sealer using the brush is a waste of time and leads to a bad result. Light coats. Clean-up. Dawn dish soap applied directly to the brush on both sides and then just a little water to let it suds up. Work the brush in a stainless steel pan back and forth really good. The start rinsing. Keep rinsing until thre are no more suds and the water runs clear. SHake the brush and let dry. Do that and just slightly beding the bristles before next use is like a new brush. Prep, prep, prep. You only stain-seal once every few years, don't skimp on the prep.

Don’t buy this from Amazon
2nd attempt to post a review. This item is available at other retailers with free delivery at $20 cheaper. I only ordered through Amazon because of the time advertised for delivery being sooner than other suppliers. It was not delivered in the promised time frame so highly recommend to get value for your purchase go else where for this purchase. Stuff is ok just follow the directions — we will see how long it lasts

Looks fresh and new
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.

great product and dries clear! Easy to apply.
Absolutely wonderful product. I was skeptical at first to purchase this item, considering I've always purchased deck stain at the local box stores. I'm so very glad I did! Works very well, easy to apply & appears is so much better than the name brand stains that only last about 3 years top! We'll see in a couple of years if the 10 years advertised holds up to the hype! Addendum: added photos and a note that 2 coats applied and still have over 1/3 of 5 gal bucket left over. The difference of shading is because of my poor power washing. Did it at night.

Worked well easy to apply
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.

Unusable, product spoiled.
I wasn't able to use the product because it was separated and unspreadable. It's probable due to wrong storage procedure but I had to return it.

Wood sealer
I had to wait until the wood dried and it went on real nice . I have not put them in the ground yet because I want to put on two coats . You can see it will do the job fine.
