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.

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!

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!!!

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.

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

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!

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 the second time we have used this product, 4 years apart. It works great.
Best sealant we have used.
