Excellent product, does what it claims to do. Super easy to apply; I used a paint roller for application of two outdoor areas with flagstone. Went on super fast, socked in and dried quickly. As instructed, I tested an area 4 ours later and it was sealed. I could detect no odor whatsoever outside. I wished I applied this to my outdoor grill and dining area 5 years ago when it was first built. Over the years, grease and spills from dining guests did stain some of my flagstone and there's no way to get that out. After application last week, we had a party and a few guests did spill and everything came up without a stain! The product is affordable too. I've used another product from this company that was also superb but for whatever reason, a quart was $45! This was far more affordable and works. Once dry, you'll see no difference between the area protected versus those that are not; it absolutely maintains the original appearance. I have an outside shower area and only wanted to use the product around the shower (no need elsewhere). It is impossible to tell where the product was applied and not applied, unless you get the area wet! Then you really see how well protected the flagstone is; water beads up. You can cover a large area rather quickly with a paint roller and matching tray. Pour the liquid in, let the roller soak it up, roll. Couldn't be easier to apply.

A fine product. Works as promised. The company was very helpful when I contacted them with a question. Fresh concrete will absorb a great deal of the sealer, so plan accordingly. Absorption on my new driveway was near the top of the range cited in the instructions (that is, lots of product per square foot of concrete). I ended up having to apply two coats. It is about the consistency of water. I used both a garden sprayer and a paint roller to apply. The paint roller works better. Once absorbed and cured, the sealer is invisible--no change in the color or surface texture of the concrete.

This stuff is great. Have sealed all my outdoor concrete and stone statuary. Wish I'd known about it sooner. Also have an old kitchen sink the stains easily, now use this every couple of months to protect it. Also regularly use to protect old ceramic tile counters that have lost their protective glaze.

Looks great easy to spray on. Has natural appearance. I will use this again

Good stuff
