Plywood
Our plywood inventory supports builders and cabinetry makers with dependable stock, clean faces, and flexible core options. Standard panels, custom layups, and specialty sheet goods—sourced to meet the demands of construction and production environments.
Plywood & Sheet Goods
At Mason’s Mill & Lumber, plywood isn’t an afterthought — it’s a working material. We stock and source sheet goods that builders and cabinetry makers rely on every day, with the consistency, face quality, and core options required for real jobsite and shop conditions.
From domestic NAUF and ULEF panels to specialty outdoor and moisture-resistant options, our inventory is built to support production schedules, not slow them down.
Custom Layups& Specialty Sheet Goods
For projects that need more than an off-the-rack panel, we offer custom plywood solutions through our sourcing and manufacturing partners.
Custom capabilities include:
Custom veneer layups
Different faces on each side (species-to-species or veneer to melamine)
Pre-finished custom panels
Cut-to-size options (within project scope)
- UV finishing
These solutions are typically handled job-by-job, allowing builders and cabinet shops to dial in exactly what the project requires — without over-ordering or unnecessary compromises.
If your project needs something specific, our team can help spec the panel before it ever shows up onsite.

Ayous / African Mahogany — Cutek Extreme Clear Finish
Ayous (Triplochiton scleroxylon), also known as Obeche, African Whitewood, Samba, or Wawa, is a lightweight tropical hardwood native to the forests of West and Central Africa. In its natural, unmodified state, Ayous has a pale cream to light yellow heartwood with a straight to slightly interlocked grain and a medium-to-coarse texture with good natural luster. It's frequently grouped with — and sold alongside — African Mahogany because of its similar workability, dimensional characteristics, and the way it accepts stains and finishes to achieve rich, mahogany-like tones.
Ayous is prized for several reasons that make it well-suited to architectural and millwork applications: it's remarkably lightweight (roughly 24 lbs/ft³), which eases handling for vertical siding, ceiling, and overhead installations; it has low shrinkage and good dimensional behavior once properly dried; and its clear, knot-free character grades produce a smooth, uniform surface ideal for high-visibility finish work. In its natural state, Ayous is considered non-durable to moderately durable against decay, which is why exterior applications require a quality penetrating finish to protect the wood and extend its service life.
Each board is finished with Cutek Extreme Clear, a penetrating oil specifically formulated to stabilize exterior wood from within. Unlike surface coatings that sit on top of the board and eventually peel, crack, or flake, Cutek carries its oils deep into the wood fibers where they work continuously to reduce moisture movement — the primary cause of cupping, checking, warping, and end-splitting. This is especially important for a species like Ayous, whose natural durability benefits significantly from a stabilizing oil. Because Cutek penetrates rather than films, maintenance requires no sanding or stripping — just clean the surface and reapply when it looks dry. The clear formulation adds no pigment, allowing the Ayous's natural cream-to-honey tone to show through initially before gradually silvering to a soft gray patina if left unmaintained with a colortone.
Because Ayous can react with iron and galvanized fasteners (causing black staining), stainless steel fixings are required for installation. Pre-drilling is also recommended, as the wood can be brittle.
Ideal for architectural siding, feature walls, soffits, porch ceilings, interior paneling, sauna applications, and covered outdoor living areas where a lightweight, workable hardwood with a refined appearance is desired.
