I applied this product to an older stone sidewalk.  I added a non-slip additive which blended well into the product. I'm very happy with the results after one coat.  I ordered another 1 gallon to add a second coat to ensure that the work I've done will last longer.  The product brought out the actual color of the stones, where before the application they all just looked like a dull tan. I posted a before and after to your Facebook page.
