Hardeners and Toppings

L&M™ SEAL HARD® is a proprietary, colorless, environmentally safe chemical solution that increases the wear surface strength of concrete floors subjected to pedestrian and vehicle traffic. L&M SEAL HARDpenetrates concrete surfaces to seal, dustproof, densify and harden them. L&M SEAL HARD floors last longer, cost less to maintain, are...

L&M™ CHEM HARD™ chemically reacts with soft free lime and calcium carbonate compounds in concrete forming dense, insoluble, chemically resistant flint-like surfaces. L&M CHEM HARD is a VOC-compliant, colorless solution of a carefully controlled concentration of 100% active sodium silicate chemicals with a non-acid penetrant. L&M CHEM HARD may be...

For the most abrasion resistant, heavy duty floor topping, we recommend L&M™ EMERYTOP 400™. This flowable, natural emery aggregate floor topping produces a very durable floor. L&M EMERYTOP 400 provides an economical, abrasion resistant solution to very severe and abusive concrete floor conditions where other solutions have failed....

For that needed abrasion resistant industrial floor topping we recommend L&M™ DURATOP HP™. This flowable natural metamorphic spinel aggregate produces a highly abrasion and chemical resistant solution for abusive impact and concrete floor wear conditions. The high concentration of the very abrasive resistant aggregates consisting of...

L&M™ TRAP ROCK™ is a combination of 100% graded trap rock and portland cement. It is a polyhedral shaped, abrasion resistant, chemically inert, non-absorbent aggregate produced from igneous rock. This dense mineral aggregate is crushed into a polyhedral shape. It is carefully graded to assist...

L&M™ EMERYPLATE FF™ is the industry's high strength dry shake for industrial concrete floors requiring additional abrasion resistance. It is the first emery aggregate dry shake surface hardener designed specifically for early application to concrete floors that must conform to a specific flatness designation....
