Description

Features:

  • A rapid hardening, low density, high strength mortar with enhanced polymer properties.
  • The thixotropic, shrinkage compensated nature of the product enables easy high build trowel applications.
  • Subject to normal conditions of use, the product will provide an effective barrier to the transmission of liquid water for the life of the structure.
  • Dense matrix offers low permeability to water, even at 10 bar pressure.
  • High bond strength exceeds the tensile strength of concrete, thus ensuring monolithic performance of the repair.
  • Excellent low sag properties.
  • Non-toxic when cured.
  • Apply by float or trowel as a render.

Substrate:

  • The areas to be treated must be free from all unsound material, i.e. dust, oil, grease, corrosion by-products and organic growth.
  • The strength of the concrete sub-base should be a minimum of 20 N/ mm².
  • The product is highly polymer modified and as a result concrete surfaces do not generally require a primer.
  • Highly porous substrates should be primed with RIW Cementseal Primer.

Application rate:

  • Normal applications: 2.6–3.0 litres of clean water per 20 kg bag, depending upon desired consistency.
  • High build applications: 2.8 litres of clean water per 20 kg bag.

Application temperature:

  • 5–35°C.
  • Protect the mortar from strong sunlight and drying winds.

Curing:

Protect the mortar from strong sunlight and drying winds with RIW Cementseal Primer, polythene sheeting, damp hessian or similar.

Usage:

  • A waterproof mortar for the structural repair, rendering and profiling of vertical, horizontal and overhead surfaces.
  • The product can also be used to provide ‘fillets’ at internal corners prior to application of other RIW Limited membranes.
