PROSOCO HCT Finishing Rinse – Post-Treatment Rinse for Marble & Limestone (5 Gallon)

POST-TREATMENT FOR STONE CONVERSION SYSTEM

PROSOCO HCT Finishing Rinse is the second step in the HCT (Hydroxylating Conversion Treatment) system, designed to complete the treatment process for carbonate stone surfaces such as marble, limestone, dolomite, and travertine.

Used after application of HCT, this finishing rinse enhances treatment performance by stabilizing the conversion layer formed within the stone. It helps ensure maximum durability, improved resistance to acid attack, and long-term protection of treated surfaces.

Ideal for restoration and preservation projects, HCT Finishing Rinse supports deeper penetration and consistent results while maintaining the natural appearance and breathability of the stone.
