We have a new brick patio and I want to spray some waterproofing on it to help seal it and hold the sand in. The sand is not the polymeric type. I don't want to use Thompson's, instead I want something better and want to apply it with a 3 gallon sprayer, 3-4 coats. I've looked at the Olympic waterproofing. What else is there to use? TIA!
