The UdiREINFORCEMENT corner strengthening mesh should be installed after the main mesh has been applied.
Whilst the render is still wet (immediately after the main mesh has been troweled in) the mesh should be placed in the corners of the openings and troweled in so that it is no longer visible on the surface of the render.
Apply a very thin layer over (less than 1mm) whilst the render is wet if required.
For more information see our how-to video above (skip to 7 mins to see how to install them).
How much do I need?
We would suggest that you use one piece of UdiREINFORCEMENT corner strengthening mesh in both top corners of each opening and the bottom corners of window openings.
These mesh is available individually or in boxes of 100 pcs
