FLX - Flexible Plaster Cladding System

FLX is a highly flexible waterproof acrylic plaster membrane, which is applied over substrates to provide a crack resistant coating.  As a non-cement based waterborne acrylic plaster system containing aggregate, it is flexible and has excellent adhesion qualities.

Key Features

The highly flexible properties of FLX provide a crack free finish on the exterior surface of the substrate, providing  the homeowner, contractor or designer with the security of added protection to their investment. 

Comes with a 20 year warranty.

Scope of Use
  • The substrate may require you to apply levelling coat of plaster first (refer to Masons Data Sheets on the correct plaster for the substrate).
  • Apply Masons Plastaseal Sealer over the first coat of plaster, this will stop the suction between FLX bedding render and the first coat of plaster, hence giving you more working time with the product on the wall.
  • Apply 3-4mm of FLX over the surface with Masons Fibreglass Mesh embedded into the wet plaster. Overlap each successive length be 50mm minimum.
  • To opening reveals mesh over the PVC flashings. Apply diagonal reinforcing strips to the corners of windows, doors and exterior openings.
  • Cure and protect from rapid drying in accordance with Masons requirements.
  • Apply 2 coats of Masons Premium Build High Build Acrylic Paint over the textured finish (if pre-coloured texture has been used then only 1 coat of paint is required). Darker colours heat up in the sun and can cause problems with expansion and contraction of the surface and for this reason the paint colour is restricted to a depth of 25% LRV or more for guarantee purposes.
