Lithium concrete hardener COUPSYL®LS-HARDENER
COUPSYL® LS-HARDENER is a clear, lithium-based liquid that deeply penetrates concrete to react with calcium and magnesium salts, sealing pores and capillaries. It prevents the penetration of water, oil, steam, and gases, removes efflorescence, and increases the concrete’s density. As a result, treated surfaces gain higher abrasion resistance and much lower permeability.
