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!

Great product to use on a lake front dock
Product applied easily with a roller. Was able to do a 2 slip dock with 2 gallons of product - seemed like it went slightly farther than expected. Shake product well and stir thoroughly after opening. We had a gallon of product that may have sat a little longer in the warehouse/shipping area and it had white "clumps" that appeared on the deck (almost like little white scabs - very latex like). They can be picked off and gotten rid of - prior to drying.

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.

Made pillars look brand new.
My porch pillars were starting to fade. My husband then painted them with this stain. And they look like they are brand new!!!

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

Shop and compare other products before you purchase this one.
I'm very disappointed. Purchase this product in March. Now it's June and product has faded and has moldy spots forming all over the surface. Put 2 coats pur labeled instructions. We are in the Texas Sun in the DFW area so I knew the sun would be hard on it. But expected it to last longer than just a few months. Wish I would have known this before all the work was entailed and an expensive product was already used. Have decided to Prime and paint wish I would have done this from the beginning.

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!

Great coverage, applies easy. Will it protect from the sun? Only time will tell.
