Maple S4S Lumber

Maple S4S Lumber is a solid maple S4S (surfaced four sides) finishing lumber, unfinished -- ready for your choice of paint, stain, or clear finish. S4S lumber is surfaced smooth on all four faces, ready for finishing or installation without additional planing. Used for custom trim, furniture components, and any application where a square, smooth board is the starting point. Available at Windsor Plywood locations across Canada.

• The hardest domestic moulding wood -- resists dents and wear better than pine, hemlock, or MDF
• Standard profile -- Interior trim, casing, baseboard, furniture components, and custom millwork
• Available at Windsor Plywood locations across Canada -- confirm stock at your local branch

Specifications

Common Uses

Cut and install as needed for your specific application. Maple is the premium choice for clear-finished and natural-look moulding. It blotches with penetrating stain -- use gel stain or dye for even colour.

Pro Tips

• S4S lumber is the starting point for any custom moulding or trim profile -- rout the edge profile you need with a router and the appropriate bit.
• For clear finish: sand to 220-grit and apply water-based polyurethane to maintain the pale colour. For stain: use gel stain or dye -- maple blotches with penetrating liquid stain. For paint: prime and paint directly.
• Available in multiple species -- confirm sizes and stock at your local branch.

Frequently Asked Questions

What does S4S mean?
Surfaced Four Sides -- all four faces are planed smooth and square. The board is ready to use without additional planing or jointing.

Does maple accept stain evenly?
Not with penetrating liquid stain -- maple blotches due to varying density. Use a gel stain or dye for controlled, even colour. For the cleanest result, apply a clear finish and let the natural pale colour speak for itself.
