Aggre-flex Meshes
Master Wall Aggre-flex Mesh is a specially woven, treated glass fiber mesh that is specially coated for compatibility with Master Wall base coats.  These smooth working meshes give Master Wall Systems crack and impact resistance while helping smooth the base coat during application.

Application Procedure
Job Conditions - Air and substrate temperature for application of the Reinforcing Mesh  must be 40°F (5°c) or higher and must remain 40°F (5°c) or higher for a minimum of 24 hours.  Provide temporary protection at all times until the wall system, including flashings, caps, and sealants, is completed to provide protection from climatic conditions and other potential damage.

Application - All imperfections in the insulation board must be rasped flush and any gaps in the insulation board must be filled with slivers of insulation.  Apply the base coat over the entire surface of the insulation board in a thickness greater than that of the Reinforcing Mesh being used (approximately 1/16" (1.6 mm) for Standard Mesh and 3/32" (2.4 mm) for Ultra Mesh).  Immediately embed the Aggre-flex Mesh into the wet base coat and smooth from the center to the edge to avoid wrinkles.  Lap all meshes except Strong Mesh and Ultra Mesh a minimum of 2-1/2" (63.5 mm) on all sides.  The reinforcing fabric must be continuous at all corners and lapped or abutted in accordance to Master Wall specifications.  The color of the mesh shall not be visible but a slight mesh pattern may be visible. The   overall minimum thickness of the base coat should be a nominal 1/16" (1.6 mm) when dry.

When applying Strong Mesh or Ultra Mesh, tightly abut all edges and let cure for a  minimum of 12 hours.  Grind any imperfections with the edge of a stainless steel trowel or grinding stone, taking care not to damage the Aggre-flex Mesh, and apply a layer of Standard Mesh, Hi-Tech Mesh, or Medium Mesh as per the directions in the preceding paragraph. To minimize wall variations, the lap of the second mesh layer should not coincide with the abutment of the first layer.

Special Conditions and Recommendations
Apply backwrapping mesh or other approved accessory at all terminations of the insulation board.  This includes at the top and bottom of all walls and at all openings.

Aggre-flex Mesh may be wrapped from the face of the insulation board onto a foundation or onto the studs of an opening on barrier wall systems.  In all cases, the  exposed edges of the insulation board must be wrapped with Aggre-flex Mesh and base coat or an approved accessory trim.

Mesh Types
Detail Mesh - super soft, pliable mesh used for backwrapping, special shapes, and detail work.

Standard Mesh -Standard weight gray mesh for wall areas and general        detailing.

Hi-Tech Mesh - Upgraded heavier weight version of Standard Mesh with good workability. 

Medium Mesh - Extra tough heavy weight mesh.  Best for areas of light traffic.

Strong Mesh - Great high traffic mesh where impacts are a consideration.

Ultra Mesh - The best for abuse!  Ultra heavy for high traffic areas.

Strong Mesh and Ultra Mesh must be used in a two-layer system with Standard Mesh, Hi-Tech Mesh, or Medium Mesh.
