HydroCoat 905-CM

  • Optimised Curing Process: Extends curing time to ensure full cement hydration, delivering maximum strength and durability.
  • Protection Against Heat and Wind: Shields waterproofing membranes from the harsh effects of sun and wind, preventing premature drying.
  • Water-Based and Easy to Apply: Utilises advanced acrylic copolymers in a water-based formula, ensuring a simple and safe application for a wide range of projects.

Newton HydroCoat 905-CM is a water-based curing compound which inhibits the effects of sun and wind on liquid waterproofing membranes and so extends the curing time to ensure full cement hydration and full strength of the product.

HydroCoat 905-CM is a specially formulated, water-based curing compound utilising advanced acrylic copolymers, which is designed for use with HydroCoat 103 2K and HydroCoat 107 Elastic 2K cement/acrylic waterproofing membranes, and HydroCoat 203-RM repair mortar, where it inhibits the effects of the hot summer sun and hot winds and so extends the curing time to ensure full cement hydration and full strength of the product.
