Lythic Solutions recently launched its Lythic Densifier, a colloidal silica-based densifier for the polished concrete industry. It can be spray applied in 15 minutes and eliminates scrubbing in, scrubbing off and disposal of the caustic gel created by silicates. Lythic Densifier is shipped as a concentrate and contains zero volatile organic compounds (VOC). Lythic Protector, a conditioner containing colloidal silica and polymers, and Lythic Cleaner, a cleansing formula that imparts additional silica into the concrete surface every time it is cleaned, are also available.
