I had concrete landscape border installed at my house three years ago. At that time the contractor sealed it with a product that gave it a wet look. I was told at about the three year mark I it would need resealed to keep that wet look. The contractor made a note on the invoice as to what sealer he used which I could not find anywhere. So I expanded my search and found this product, the 350. I decided to give it a try. This product applied very easy and produced the exact same wet look as when the boarder was originally installed and sealed. The only negative is the price per gallon/5 gallon is expensive in my opinion.
