Graphex Cavity System is a cavity-based exterior insulation and finishing system (EIFS) wall cladding. It is an external wall cladding system for residential and light commercial type buildings where domestic construction techniques are used. The systems consists of Neopor®, a graphite composite board or expanded polystyrene (EPS) sheet fixed over battens to form a 20mm cavity. The render and plaster coating system consists of a 3 - 4mm thickness fibreglass mesh reinforced, polymer-modified cement based render, 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 sponge, patterned, adobe or a sprayed textured finish. The system incorporates a primary and secondary means of weather resistance (first and second line of defence) against water penetration by separating the cladding system from the external wall with a nominal 20mm drained cavity.

Carry out an annual inspection and record this on the Resene Construction Systems Maintenance guide. For best results use Resene Paint Prep and Housewash liquid concentrate. Apply the diluted solution with a soft broom, and wash off with copious amounts of fresh water. Most detergents have a detrimental effect on fish life so avoid letting the washings run off into the storm-water system. DO NOT use harsh solvent based cleaners.
