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. With $12 flat-rate shipping per 50lb box, it’s the cost-effective choice for makers, schools, businesses, and DIYers.

• 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. Please reach out to us at support@makerstock.com for a quote.
