Lythic Densifier

Lythic Densifier with reactive colloidal silica is a densifier/hardener for concrete, used to improve the performance and appearance of concrete floors.

It increases surface hardness, compressive strength, abrasion-resistance, and liquid penetration-resistance. It is an integral part of the concrete polishing process, which can yield a glossy, reflective appearance similar to terrazzo or polished natural stone. Lythic Densifier reduces dusting, efflorescence and ASR. It is a zero-VOC, non-toxic, safe-to-handle liquid that does not require scrubbing in, removal, or hazardous residue disposal, and does not leave discoloring mineral salt deposits on concrete.

Lythic Densifier is 99.5% pure silica in nano-scale particles, suspended in an ultra-low surface-tension liquid using a proprietary, “green” manufacturing process. It reacts with calcium hydroxide (lime) in the concrete matrix to create additional calcium silicate hydrates (CSH), the active binder in cement paste, becoming a permanent part of the concrete, and increasing the density of the concrete surface.  Colloidal silica is unique among densifiers in that it also bonds to silica in concrete, and bonds to itself, enabling it to build up density in a way that silicate densifiers cannot.
