Phenolic Baltic Birch Plywood (Light Brown) - 18mm

Durable, waterproof phenolic Baltic Birch plywood for cabinets, jigs, sleds, marine and boat applications, and heavy-duty builds – perfect for makers, DIYers, and businesses. Also known as film-faced plywood or HDO plywood (high-density overlay), our high-quality phenolic plywood features a Baltic Birch core made from multiple layers of hardwood birch veneers, offering a mostly void-free, stable, and durable structure. Both sides are coated with a smooth, glossy phenolic resin film (120 g/m²), providing a wear-resistant, waterproof, and scratch-resistant surface. The plywood’s distinctive edges showcase attractive, uniform stripes of alternating light and dark hardwood veneer, making it ideal for exposed-edge designs. Prized by woodworkers for its uniformity, workability, thick face veneers, and excellent screw-holding ability, this plywood is perfect for laser cutting, CNC machining, furniture, marine applications, and construction. Its exterior-grade glue ensures suitability for outdoor and high-moisture environments, such as boat decking (often covered with marine carpet) or concrete formwork. Available in 3/4" (18mm) in stock sizes up to 24” x 48”, or order custom-cut panels online here or via support@makerstock.com.

Specifications: Material: Baltic Birch Plywood core with hardwood birch veneers, coated with light brown phenolic film (120 g/m²) on both sides. Please note, the edge of a full 4'x8' sheet of material is painted. Resulting cuts to your stock size may result in some edges showing natural grain color and/or brown overlay color. Thickness Options: 3/4" (18mm, ±0.5mm) Density: 700 kg/m³ (0.025 lb/in³). Finish: Smooth, glossy, moisture- and scratch-resistant dark brown phenolic film; edges may show natural birch grain or black overlay Tolerances: Cut tolerance of +/-0.188" for all panel dimensions (in inches). Glue Type: Exterior-grade, waterproof. Workability: High-density (700 kg/m³ or 0.025 lb/in³), moisture-resistant, and excellent for screws and fasteners without splitting. Pro Tip: To ensure longevity, seal all exposed edges after cutting or building to protect against moisture. Use a carbide-tip blade with a high tooth count or apply masking tape and score the phenolic surface before cutting to avoid chip-out. For drilling, use carbide bits and place sacrificial material beneath to prevent blowout; taping also helps. Touch up chips or blemishes with acrylic paint pens. Clean with a non-abrasive cleaner to avoid damaging the glossy surface. FAQs: Is phenolic Baltic Birch plywood good for laser cutting? Yes, it engraves cleanly with CO2 lasers for durable jigs or signage. Can I use phenolic plywood outdoors? Yes, its exterior-grade waterproof glue and phenolic coating make it ideal for marine decking, outdoor furniture, or construction, but seal edges for maximum weather resistance. What thickness is best for furniture or construction? We suggest 3/4" (18mm) for sturdy cabinets, concrete forms, or trailer walls. What kind of fasteners should you use with phenolic? When used in exterior applications, stainless steel or corrosion resistant fasteners work best. What’s the difference between phenolic plywood and regular Baltic Birch plywood? Phenolic plywood has a waterproof phenolic film coating for moisture and scratch resistance, ideal for marine or outdoor use, while regular Baltic Birch lacks this coating, offering a natural wood finish better suited for indoor, exposed-edge designs. What does the 120 g/m² phenolic film density mean, and how does it compare to 220 g/m²? The 120 g/m² film weighs 120 grams per square meter, providing a thin, waterproof, and scratch-resistant coating ideal for marine decking, cabinets, and workshop jigs. A 220 g/m² film is thicker and more durable, suited for heavy-duty concrete forms or industrial flooring, but it’s heavier and costlier. The 120 g/m² film balances affordability and durability for most maker projects. Can I buy a full sheet of material? We do have 4’x8’ sheets of Phenolic available for purchase.
