Product overview
Performance and application overview.
X-MT Cementitious Penetrating Crystalline Waterproof Coating is a high-performance gray powder material formulated by blending active chemical components with Portland cement. This advanced concrete waterproofing solution uses water as a carrier to penetrate deep into concrete structures, reacting with unhydrated cement particles to form durable crystalline deposits. These crystals effectively fill pores and micro-cracks, providing permanent concrete protection against water ingress and enhancing overall structural integrity.
Key applications include：
tunnels, dams, reservoirs, power plants, and basements. With superior penetration up to 30 cm, it withstands hydrostatic pressure exceeding 120 meters and offers self-healing for cracks up to 0.4 mm. Safe for potable water and food industry use, it's compatible with various coatings and easy to apply.

Product usage
Application and installation guidance.
X-MT Cementitious Penetrating Crystalline Waterproof Coating is ideal for concrete waterproofing in demanding environments. Applications include tunnels, dams, reservoirs, power plants, nuclear stations, cooling towers, subways, bridges, underground walls, airport runways, pile foundations, wastewater facilities, water tanks, basements, roofs, bathrooms, and leak repairs.
Construction Methods:
(1) Trowel Application: Clean substrate, level uneven surfaces, remove stains, apply evenly (1.4-1.7 kg/m², 1.0 mm thick).
(2) Roller Application: Roll evenly at 1.4-1.7 kg/m² for consistent coverage.
(3) Dry Spraying: Apply post-leveling, tamp smooth, maintain moisture in hot weather.
Key Features in Use: Superior penetration (30 cm), water resistance (>120m pressure), self-repairing crystals, and compatibility with paints/epoxy.
