Seal-Krete Lock-Down Concrete Bonding Primer is a selfcross-linking epoxy primer for concrete surfaces which provides superiortopcoat adhesion and durability. Nanotechnology locks topcoats into thesurface to reduce peeling and hot tire pickup, while the acrylic formulaallows for use over previously coated surfaces. Low odor, low VOC epoxy-bonding formula works on coated and uncoated surfaces and dries clear. Fromthe Manufacturer SEAL-KRETE LOCK-DOWN is a self cross-linking epoxy floorbonding primer for concrete surfaces. Its nanotechnology improves adhesionwith its ultra-fine, nano-sized particles that penetrate deeply into theconcrete, while locking down the chalk and providing a clean, sound substratefor a topcoat of water-based floor paints, stains and textured coatings.
