Since it takes time and effort to pressure wash and seal a patio and walls, I wanted a product that looked great in the end. Although more expensive than cheaper water based sealants, Foundation Armor did not disappoint. The application was easy - I used an inexpensive 1 gallon sprayer and a roller to apply the first coat. This allowed for adequate coating of the entire paver, not just the top surface. The second coat I applied with just a roller. The result are pavers that have a wet look that shimmer in the sun and bead water in the rain.
