Li-Sil Sealer is an environmentally friendly, VOC free, lithium silicate concrete floor densifier, hardener, and sealer. Li-Sil Sealer is designed to penetrate untreated, bare concrete surfaces providing a permanent glossy, dust proof floor. Aqualon L-100 reacts quickly with the floor surface to produce initial and ultimate hardness. Li-Sil Sealer shows great effectiveness when used in conjunction with a floor polishing machine, yielding a highly protected, hardened, and densified floor.
