EIFS Revealed

Base Coat with Embedded Mesh

The EIFS base coat is installed over the insulation or heavy duty reinforced base (as illustrated).   Reinforcing mesh is embedded into the wet base coat.  Manufacturers have different colours and logos to identify their mesh.  Beware of mesh that is not supplied by the manufacturer.  Legitimate mesh is tested under a very severe protocol that few products can meet.  It is a critical component for the long-term durability and performance of the system.

Regular mesh is over lapped a minimum of 65 mm.  In this illustration the mesh overlaps the prewrapped starter by at least that amount.  Additional strips of mash may be used to connect the prewrapped starter pieces where they are butted together.  In all cases with EIFS installation, the reinforcing mesh must be overlapped to insure continuity.
