PROSOCO LS/CS – Concrete Hardener, Densifier & Dustproofer (5 Gallon)

PROSOCO LS/CS is a penetrating silicate treatment designed to harden, densify, and dustproof concrete surfaces. It reacts within the concrete to form durable compounds that increase surface strength and eliminate dusting.

Suitable for both freshly placed “green” concrete and existing floors, LS/CS provides a fast, efficient alternative to traditional hardeners. Its easy application requires no scrubbing or flushing—simply spray and spread.

This treatment improves durability, simplifies maintenance, and enhances the overall performance of concrete floors without contributing to Alkali Silicate Reaction (ASR).
