The Duke Company is proud to carry SpecChem products including Spec-O-Lith. Spec-O-Lith is a Liquid Fluosilicate Hardener Concentrate. SPEC-O-LITH is a water based solution of fluosilicates, formulated to harden and dustproof concrete floors and improve the wearing characteristics of new or aged concrete and terrazzo. Provides a chemically hardened surface with increased resistance to water, chemicals (acids, alkalis, etc.), grease and oil absorption. SPEC-O-LITH is especially effective in strengthening weak, soft or dusting concrete surfaces. SPEC-O-LITH is ideal for factories, warehouses, schools, hospitals, breweries, aeries, food processing plants, and service garages. SPEC-O-LITH is compatible with most conventional carpet and tile adhesives.

Surface must be clean, dry and free of all oil, grease, coating or residues that prevent absorption of chemical into surface. On new concrete surfaces, wait a minimum of 14 days (28 days, if possible) before applying. Product must be diluted with clean water prior to use. Use a plastic container or original container for this as product is corrosive. See coverage/dilution chart. Apply only when temperatures are above 40°F. Apply by spray (low pressure), squeegee or push broom. Two applications are generally necessary, each after the other has dried. AVOID puddles to prevent area whiteness. To help avoid surface whiteness on terrazzo floors, or other extremely dense concrete floors, rinse with warm water before SPEC-O-LITH dries completely. If whiteness occurs, it is an indication that either the diluted solution is too strong or the floor has reached its maximum absorption of the chemical. Recheck dilution ratios or add additional water to solution until whiteness no longer occurs. Remove whiteness by immediately scrubbing with water and a stiff bristle broom.

Texture and absorption of surfaces dictates final coverage rates. Warm water washing speeds removal. For Concrete: Allow each application to dry before applying the next application. Texture and absorption of surfaces dictates final coverage rates. Drying Time: 4 to 8 hours depending on temperature & humidity. Immediately clean tools with warm water.
