Images for illustration purposes only Watco Epoxicote High Build Primer is specially designed for use with Watco Epoxicote High Build. Epoxicote High Build is a high performance 100% solids epoxy resin coating, which benefits from the use of this primer on bare concrete surfaces. Use the primer on hard, smooth, power floated concrete which would otherwise reject a paint coating. This eliminates the need for grinding or costly shot blasting. Also use on weaker, porous bare concrete surfaces.
