Silicon-Based Penetrating Water Repellent

Low-viscosity penetrating water repellent that forms nanoscale hydrophobic interfaces inside porous concrete, masonry and stone substrates.

Silicon-Based Penetrating Water Repellent

Technical Overview

CW-WP-01 is not a surface film. It penetrates capillary pores and microcracks, then creates a hydrophobic interface while keeping the substrate breathable.

It is designed for concrete durability, masonry retrofit, stone protection and water-repellent treatment on porous mineral substrates.

2024W06363 report: 19% water absorption ratio, 0 mm permeability and no staining under multiple aging conditions.
