Repells Water and Looks Great

Stain applies well but prepare for spills and clean up. Protect areas you don't want covered. It's a watery type product so it will drip each time you go from a pan or the bucket to the wood structure. Quality of the stain seems great so far. I love the grey color. Applied 2+ coats and the results so far have been positive. Water runs off the deck so it should be well protected for years. Very pleased with this stain. Delivery from Amazon was prompt (next day as I recall). Made ordering so much easier than running to the local box store.

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!

Company changed the thickness, or lack of,to a product that is thicker

Right away I will say the 4 stars are because I just applied the sealant the other day and the fifth star will be if/when it performs over a bit of time. That said, I'm putting this out there due to having used the old formula that I bought last year and the new formula that I just bought because I needed more to complete my project. The formulations are the same but the thickness is much better now. The old was no more consistent than water and the new is like thinned down paint and therefore much better to work with. The company was getting the feedback about the thinness of their product and they simply thickened it. It made a big difference for me not only working with it but also I gained coverage. One gallon of the old covered roughly 150 square feet and the new is covering at a rate of 275 square feet per gallon which is obviously significant. The product sets up nicely and makes the appearance of the treated yellow pine deck boards more vivid which is what I like.

Buy enough for a second coat!

The media could not be loaded. My initial thoughts:It’s very watery and easy to spread. It dried with a blueish hue before curing and adding a slightly darker tint to the existing color. With that in mind, it will NOT cover any imperfections from washing/prepping.Not sure if it was just my deck wood or not, but it takes a good bit to really cover the surface well. A second coat is an absolute must. I couldn’t even tell it had been treated after only one coat. The second coat really brings out the product’s good qualities.I used about 3.5 gallons of the 5 to cover my roughly 600 sq/ft deck. As mentioned, a little can go a long way, but I found that if I really lathered it on it set better.It dries very quickly. Even with a heavy coat and indirect sunlight it would be dry to the touch in minutes after the first coat. The second coat remains tacky for about 8+hours.First rain came after 32 hours of curing. Seems to be working well!

Worth the money

Easy to use, no smell, darkens the wood slightly and on the sticky side. All in I would recommend this item.

Not Good!!

I was so disappointed with this product! After thorough research and reading reviews I thought this would be the best thing for my outdoor cedar bar top. Boy was I mistaken! After following the instructions to a T, we installed the bar top on our covered patio. Thought everything was great until 2 days later that I noticed the light rain we had the day before had blown the drops onto the bar top and it was stained with dirt spots all over one end. They wouldn’t come out so we took it down and resanded the wood and started over and used epoxy instead. Now it looks beautiful and won’t be getting stained again.This product was worthless!

good product

It arrived with some small leakage which covered the directions for use. I was able to get the directions for use on the internet. I ordered the clear but the liquid is milky white. I tested on a spare piece of wood and found that it dries clear. The product goes on very easy and did not leave brush marks, time will tell how well it holds up.

Great Product! Would purchase again!

I just coated 2 decks with this sealer & it done great. Water just bubbles up on it. I brushed mine on but you do have to put 2nd coat on pretty quick, while 1st coat is still damp or it will bubble up on the first coat like water sitting on it. I used the clear, it looks great! Would definitely purchase again!
