Richply Armorbond® 2-Step Medium Density Overlay (MDO) is a premium overlaid multi-purpose structural plywood panel widely used by highway departments (DOTs) and private commercial sign shops across North America for sign fabrication. Panels can be specified with overlay on both the face and back or on just one face. The Exterior glue bond classification is best for sign applications as it resists exposure to extreme conditions of moisture and temperature.

Richply Armorbond is a versatile panel that provides customers with excellent value; the quality of 2-Step manufacturing combined with the toughness of a plywood structural panel and the “armored durability” of an overlaid surface. In addition to the sign industry, Armorbond is suitable for residential construction and do-it-yourself (DIY) applications.

Richply Armorbond accepts paint easily and has a superior-quality surface sanded smooth for finishing in either an interior or exterior environment. The MDO paper overlay provides a hard, smooth, densified surface which serves to mask most of the underlying wood grain characteristics that might be visible with the 2-Step panel construction. Richply Armorbond enjoys a quality reputation for long-lasting durability and quality workmanship.

Richply Armorbond 2-Step MDO is manufactured to CSA-0121 Douglas Fir Plywood as well as US Voluntary Product Standard PS-1.

Applications:

Richply Armorbond is also commonly used in the residential construction, do-it-yourself (DIY), and industrial markets. It is suitable for use in miscellaneous applications such as garage doors, soffits, fascias, finished columns, gable ends, chimney enclosures, garden boxes, work surfaces, storage bins, totes, crates, pallets, cabinets, shelving, furniture, signs, billboards, and truck and trailer linings.

Armorbond is an unfinished wood product that should not be left exposed to the elements without treatment. For exterior applications, panel surfaces require an acrylic latex primer and two all-acrylic latex topcoats. Panel edges require filling, priming, and top-coating with a least two coats of acrylic, polyurethane, or polyurethane-acrylic finishes. Consulting with a paint store to select companion products designed to be used together and preferably by the same manufacturer is recommended.

Key Advantages:

• Paintability – superior smooth surface easily painted using primer and compatible top-coat paints.
• Superior Masking – sanded 2-Step plywood substrate provides improved smooth surface quality when combined with paper overlay helps reduces visible grain and wood characteristics beneath the paper.
• Machinability – machines well during sawing, drilling, routing and boring; veneer-core provides excellent screw-holding.
• Weatherability – when combined with a quality finish on surfaces and edges, provides a durable exterior.
• Hardness – provides a smooth, densified surface that resists scuffing.
• NAUF – manufactured with no added urea-formaldehyde.
