Superior Paintability In A Multi-Use Overlaid Plywood Panel

rezon® MDO (medium density overlaid) plywood is a multiple-use industrial panel whose surface provides superior paint-holding characteristics and is highly resistant to chemicals and weather when properly coated. For over four decades, Crezon® MDO has been used for: boat hulls and structures, truck doors, signs and displays, pickup truck floors, rental trailers, barricades, soffits, gable ends, siding, commercial building fascia, agricultural animal confinement structures, screens and fences, garage doors, factory and warehouse wall liners, ducts and troughs, cabinets and specialty crating. Wherever a smooth, easily painted, durable surface is required, Crezon® MDO is a superb choice.

General
1. Crezon's smooth surface is obtained by sanding the plywood substrate before the overlay is applied. This "two step" process results in less face grain show-through for better looking finishes.
2. Crezon's Medium Density Overlay provides just the right "tooth" for rapid, even paint application, so less material is required per coat. It is the preferred panel when long-lasting paint or coating performance is required. Coverage is so uniform that in most cases a primer and a single top coat are sufficient for years of trouble-free performance.
3. Olympic Panel manufactures its own overlays and plywood, so quality is assured throughout the production process.

Standards
All Olympic Panel Crezon® MDO Panels meet or exceed the exterior-grade plywood requirements of U.S. Product Standard PS-1 and bear the exterior grade-trademark of the American Plywood Association. Panels are produced with B-grade faces and C-grade inner plies. The overlay may be specified on one or two sides. Olympic Panel can also design a panel core configuration to meet specific end use requirements.

Structural Qualities
Crezon® MDO exceeds the structural qualities of most grades of raw plywood. Compared to particleboard and wafer-board it is stronger, stiffer, has better racking resistance and resists creep better. For structural calculations refer to APA Design Specifications for engineering details and formulas.

Features and Benefits
. Has a higher strength to weight ratio than reconstituted wood panels. Limits checking and weathering by masking the grain of the raw wood.
. Overlaid surface increases performance and durability of plywood, yields smooth, splinter free surface ideal for painting.
. May be used as substrate for special industrial coating systems.
. Can be pressure-treated with preservatives or fire retardant chemicals by wood treating companies.
. Withstands extremes of temperature, water and ultraviolet when properly coated.
. Resists chemicals-diluted acids, mild alkalies, etc.-when properly coated.

Finishing
Crezon® MDO panels take paint uniformly with good chemical and mechanical adhesion. Paint lasts approximately three times longer compared to raw plywood under normal weathering conditions. Use top quality coatings and follow manufacturer's instructions. Avoid oil base stains, shake and shingle paints. All edges should be sealed.

The prime coat is the most important coat. Oil/alkyd primers are recommended; latex primers also work well. The surface should be clean and dry before painting. No other surface preparation is needed. Do not apply too thin a prime coat. The primer should be applied to yield about 1 mil dry film thickness. Apply within the spreading range recommended by the manufacturer to obtain proper thickness.

Top Coats
Once Crezon® MDO has been properly primed, it may be top-coated with a variety of finishes including solvent-thinned and water-thinned paints and enamels. To insure compatibility between the topcoat finish and the primer, both should be from the same manufacturer. For best results, follow the manufacturer's application instructions. Some finishes should not be applied to Overlaid plywood. These include automotive primers and enamels, lacquer undercoats and topcoats.

Edge Sealing
The most vulnerable portions of overlaid plywood are the edges. Because they absorb water which can lead to finish and surface deterioration, the edges require the most effective protection. Two coats of edge sealer must be applied for adequate protection against moisture penetration. Any conventional method of application may be used as long as adequate coverage is obtained.
