SlabArmor Closer

colloidal silica concrete densifier/hardener

SlabArmor™ Closer is the second step in the SlabArmor system. This colloidal silica densifier/hardener is applied after power troweling has been completed. A single application is applied to the surface and requires no scrubbing or rinsing. Its reactive formula penetrates deep within the capillaries of the substrate to form insoluble calcium-silica-hydrate, hardening and densifying the substrate.

The result is a more water, stain, and abrasion resistant surface, extending the life of the concrete.
