A self cross-linking epoxy floor bonding primer for concrete surfaces. It's nanotechnology improves adhesion with ultra-fine nano-sized particles that penetrate deeply into the concrete, while locking down the chalk and providing a clean, sound substrate for a topcoat of paint. Using Lock-Down will significantly reduce the potential for peeling, cracking, blister, or chipping. It is a great primer for any concrete substrate to lock down paint and the preferred primer for Seal-krete epoxy seal, Floortex, and Granitex textured coatings. Covers approximately 150 to 250 sq. ft. per gallon. Dries to touch in 2 to 4 hours and topcoated in 8 hours.
