FLX: An Exterior Plaster Coating System with Resilience

FLX is a highly flexible, durable and water-resistant acrylic plaster membrane that is applied over substrates* to assist in providing resistance against cracking.

More architects are opting for Flexible Acrylic Plaster instead of cement based plaster. Cracking in any plaster coating is not only unsightly, but can also allow water into the house and begin the process of expensive building damage.

With Masons FLX, houses are wrapped with a flexible, durable, water-resistant render, greatly reducing the chance of moisture damage to the building through the substrate.

This non-cement based waterborne acrylic plaster system contains aggregate to provide flexibility and excellent adhesion qualities, making it a favourite among plasterers.

Warranty system

FLX has a 20 Year system warranty, is manufactured in NZ for New Zealand conditions and it's a proven product that has been on the market for over ten years.


*Masons has plaster specification systems available for the following substrates:

  • Masons: ThermalCrete, Enviro AAC, XRV 
  • Brick and block
  • Monotek sheet
  • XRV and block
