Our 18mm Spruce Plywood Cut to Size service supplies precision-cut sheets ready to install. The panel combines a stable multi-ply softwood core with smooth spruce faces, giving clean edges and a neat finish that accepts paint, stain, clear coats or laminate. It’s a dependable, great-value choice for flooring overlays, furniture frames, shelving, worktops/sub-tops, partitions and general joinery.
- Firstly, the 18mm thickness provides excellent stiffness and load-bearing capacity for demanding builds.
- Next, custom cutting saves time and waste—your panels arrive square, accurate and ready to fix.
- Additionally, the smooth spruce surface delivers crisp edges and an even decorative finish.
- Moreover, consistent construction helps reduce voids—ideal for CNC routing and accurate templates.
- Finally, great value keeps projects on budget without compromising performance.
Choose 18mm spruce plywood for subfloors and overlays, cabinet carcasses, shelving, boxing-in and soffits, room dividers and wall panels, workshop fixtures, site hoarding, jigs/templates, and general carpentry. For humid rooms or exterior exposure, select a moisture-resistant/exterior grade specified for those conditions and seal all cut edges.
Enter width × length for each piece and add the quantity. If you’re fitting into a frame or rebate, allow small clearances and movement. Want to minimise off-cuts? Send your cut list—we’ll suggest an efficient panel layout.
Support sheets while cutting; use fine-tooth blades for neat edges and sand lightly before finishing. Fix with wood screws or ring-shank nails at the recommended spacings, or bond with quality wood adhesives into sound framing. Pre-drill near edges and seal exposed edges where moisture may be present. Always follow current building guidance.
