Our patio was due to be resealed and it was looking okay, but needed help to bring it back to life. After researching my options, I decided on the Armor AR350 Solvent Based Acrylic Concrete Sealer from Foundation Armor. Basically a three day process, starting with a good power wash, first coat, and then final coat on day three including the Armor Non-slip additive. I chose the roll on application method. For the price and ease of use, I am highly satisfied. Definitely a solid 5 star product.
