Primer coating is s special material used on concrete surface to create a compatible layer between surface and other acrylic resin coatings like resurfacer or color or cushion.
It’s a base layer applied to the surface before resurfacing or applying acrylic systems. Its primary purpose is to improve grip by binding the base surface and other layers of the Acrylic court system. It also ensures a long-lasting, uniform, and durable surface by preventing the seepage into upper layers.
