Description

EctoFlex is a two component, flexible, polymer based cementitious coating designed to prevent moisture ingress, under hydrostatic pressure as well as air leakage and vapour diffusion. EctoFlex is light grey in colour when fully cured.

Advantages
  • Used for both exterior or interior applications
  • Retains flexibility to -20°C
  • Very low permeability
  • Long-term weathering
  • Excellent adhesion
  • Permanently bridges minor cracks
  • Water-based technology allows for simple, safe application and easy clean-up
  • Liquid application assures a monolithic, seamless membrane
  • Vapour Barrier 18ng/pa.s.m2 (0.3 perms)
Uses

EctoFlex is used as a waterproofing membrane designed to provide moisture protection in a variety of both vertical and horizontal applications, including foundations walls, tunnels and other earth sheltered structures, plaza decks, mud slabs and other split slab construction, wet rooms and balconies. EctoFlex can also be used as a water resistive (WRB) air/vapour barrier within the building envelope. It may be applied to most common substrates such as concrete block, cement board, glass-mat coated gypsum board, and brick.
