This “PM” polymer-modified washer is crafted from high-density, polypropylene created to secure fiberglass mesh, wire mesh, or expanded lath over foam insulation boards. This is an excellent product for attaching rigid insulation boards to various substrates and poly-modified stucco applications. For maximum flexibility, the DP300 EIFS PM washer can be screwed, nailed, or shot.

Traditionally, class PM EIFS use extruded polystyrene insulation (XEPS), and a thick, cementitious base coat applied over mechanically attached glass fiber reinforcing mesh, with joints similar to traditional stucco. PM EIFS has evolved to include different insulation materials and base coats. A standard finish is used, although an elastomeric finish can be used to bridge hairline cracks that may occur in the thicker base coat.

Benefits and features:

• Strong polypropylene construction provides impact resistance and long life
• Low-profile washer design enables flush seating
• Keyholes create a powerful EIFS base coat mechanical bond
• Large, 1-3/4" head diameter for extra wind load holding
• Used for foam, plaster, lath, and plastic lath attachment

Note: The DP300 washer is not recommended for polymer-based systems.
