Masonry Overlay System

The Masonry Overlay System is an exterior insulating and finishing system for concrete masonry, in-situ or pre-cast concrete walls.

The system consists of Graphex (Neopor®), expanded polystyrene (EPS), extruded polystyrene (XPS) or polyisocyanurate (PIR) sheets fixed to the concrete masonry or concrete walls with adhesive mortar and mechanical anchors. The plaster coating system consists of a 5 mm thickness of fibreglass mesh reinforced, polymer-modified, cement-based plaster, which is finished with a cement-based finishing plaster that is then painted with a 100% acrylic-based paint system. The chosen finishing plaster is applied to give a range of different appearances, such as a sponge, patterned, adobe or spray textured finish.
