MonoMesh XF is used for the prevention of cracking in render around openings and large expanses of masonry. The mesh can be purchased as part of the Monocouche XF render system. Monocouche recommend the insertion of alkali resistant fibre mesh, to areas of typical stress points in the construction, i.e. above and below all openings such as windows and doors and at horizontal junctions of dissimilar substrates e.g. ring beams & coursing bricks. This is good practice and should be included in tender documents and technical recommendations for all Monocouche products. How to Install MonoMesh XF Embed the mesh into the Monocouche when preparing the substrate for beading of the render. If using polymer modified key coat (MonoBase XF) it can be embedded in this application. Cut the mesh into a strip that will extend past the junction or point of weakness by 300- 500mm or depending on the size of the masonry substrate cover the entire fa§ade. Press the mesh into the fresh render evenly with a trowel or spatula and then over lay with further render to encapsulate the mesh.
