Newton Hydrocoat 103 2K

HydroSeal 103 2K – Two-Part, High-Adhesion, Hard-Wearing Cementitious Waterproofing Coating

HydroSeal 103 2K is a high-performance, two-part cementitious waterproofing membrane with exceptional adhesion to concrete and steel. Designed for fast application via airless spray or trowel, this durable, UV-stable coating provides superior resistance to water ingress, chemicals, and chloride attack.

With the ability to resist 10 bar of positive and negative water pressure, HydroSeal 103 2K is particularly suited for below-ground structures, podium decks, balconies, car parks, and water-retaining structures. Its high alkalinity and chemical resistance make it an ideal protective barrier for reinforced concrete in sulphate-contaminated environments.

For reinforcement over static joints and direction changes, HydroSeal 912-RT is recommended.
