Two-coat polymer-modified render systems
Mapei, Rockcote, Sika and Fosroc two-coat polymer-modified cementitious render systems for full render removal and replacement, render repair, and facade re-render works.
4 product systems
Two-coat sand-cement render systems
Traditional two-coat sand-cement render systems — scratch coat and finish coat — for render repair and replacement on masonry and concrete facades.
3 product systems
Fibre-reinforced render systems
Polypropylene and glass-fibre reinforced render systems providing enhanced tensile resistance and crack distribution — for facades with elevated movement or cracking risk.
4 product systems
Acrylic spray-applied render systems
Factory-blended acrylic/cement renders applied by machine spray — typically to AAC and lightweight construction substrates — Rockcote, Weber and Boral systems.
3 product systems
EIFS render systems
External Insulation and Finish Systems (EIFS) incorporating EPS insulation board with mesh-reinforced polymer render finish — repair, replacement and partial patch systems.
4 product systems
Salt-resistant renovating render systems
Render systems specifically formulated with reduced portland cement content and specialist polymer admixtures to resist chloride and sulfate attack in coastal and salt-affected environments.
3 product systems
Breathable / vapour-permeable render systems
WTA-compliant vapour-permeable render systems — sd value <0.14m, high pore volume >35% — allows moisture vapour to escape without disrupting the render surface.
3 product systems
Bonding agent and primer systems
Acrylic, SBR and epoxy bonding agents and cementitious bonding slurries applied to substrate before render to improve adhesion on smooth, dense or low-absorption concrete and masonry.
4 product systems
Salt-retardant substrate treatment systems
Crystalline and penetrating silicate-based salt-retardant treatments applied to masonry and concrete to reduce capillary salt migration before re-rendering on salt-affected facades.
3 product systems
Saline-resistant primer and slurry systems
Cementitious bonding slurry and polymer primer systems formulated for salt-affected substrates — applied before salt-resistant or breathable render on coastal and contaminated facades.
