HydroCoat 203-RM

  1. Swift Structural Repair: HydroCoat 203-RM, a single-component, fast-setting Portland cement-based mortar, excels in durable concrete repair. Ideal for roads, runways, bridges, and more, it’s polymer-modified and fibre-reinforced, quickly developing high adhesive and compressive strength.
  2. Adaptable Strength, Rapid Cure: Physically and chemically compatible with host concrete, HydroCoat 203-RM ensures fast-curing and reliable strength development. As a single component requiring only water, it’s effective up to 100mm deep. For high-performance screeds or deeper repairs (up to 300mm), bulk it with clean, washed, sharp sand.
  3. Reliable Performance in All Conditions: HydroCoat 203-RM maintains strength even in low temperatures. Its enhanced polymeric properties and rapid cure make it versatile for various applications, ensuring robust and lasting results.

Single-component, fast-setting, Portland cement-based structural mortar, used primarily for the durable repair of concrete. Ideal for roads, runways, bridges, decks, floors and footpaths.

Polymer-modified, and fibre-reinforced, HydroCoat 203-RM is physically and chemically compatible with the host concrete, quickly exhibiting high adhesive and compressive strength.

As a single component, requiring only the addition of water, the resulting mortar is rapid curing with enhanced polymeric properties and reliable strength development which is not significantly affected by low temperature use. The mortar can be used as supplied up to 100mm deep, or bulked out with clean, washed, sharp sand to form a high-performance screed or for floor or deck repairs up to a maximum depth of 300mm.
