The product was easy to apply with a roller. A week after it was applied It appears to be working well as water is beaded up on the surface of the concrete treated and there is no discoloration of the concrete either dry or wet. It meets my expectations. I will note that the concrete treated was very "thirsty" and the sealer just barely covered the minimum identified square footage coverage. This is not a criticism of the product but just a helpful comment to anyone wanting to use the product - be sure to obtain enough before you start.
