It can be applied directly to suitable brickwork, blockwork and concrete, or over an appropriate Parex base coat where required by the system specification.
Monorex GM is coloured throughout using mineral pigments, allowing the render to form the completed decorative surface without additional masonry paint. The Natural White G00 shade offers a softer alternative to a bright-white finish and should be checked using a physical sample before ordering.
Apply the render by hand or spray machine to create a medium scraped or spray-textured finish. At a typical finished thickness of 15mm, each 25kg bag covers approximately 1–1.1m².
