Plywood is a versatile material used in various construction and DIY projects. It's popular for its strength, flexibility, and affordability. However, to achieve a high-quality finish and lasting results, it is important that you use some specific techniques. In this final part of our plywood series, here are some top tips to help you get the most out of your plywood projects.
Cutting
Cutting plywood can be challenging due to its tendency to splinter along the edges. To minimize this, use fine-tooth saw blades or a sharp blade designed for plywood. Circular saws and table saws are commonly used. Make sure you cut with the good side facing down when using a circular saw and facing up when using a table saw. This reduces tear-out on the visible side. Scoring the cut line with a utility knife before sawing can also help prevent splintering.
Plywood sheets are large and can be unwieldy. To avoid accidents or poor cuts, always support the plywood adequately while cutting. Use a sawhorse or a table to provide you with a secure surface for cutting. A sacrificial piece of plywood underneath the one you're cutting can help prevent the saw blade from splintering the bottom edge as it exits the cut.
Handling and Storage
Plywood should be stored flat to prevent warping. If storing vertically, ensure it is well-supported and doesn’t lean at an angle that could cause it to bend. Avoid exposure to moisture, as plywood can absorb water and swell or delaminate. If working in a humid environment, seal the edges and surfaces with a primer or paint to prevent moisture penetration.
Fixing
When fixing plywood it’s important to use the right type, whether you are using screws, nails, or glue. Screws specifically designed for wood are best for plywood because they provide better holding power without splitting the layers. Pre-drilling holes can help prevent splitting, especially near the edges. If using nails, choose ring shank nails, as they hold better in plywood than smooth nails. Wood glue should be applied evenly and clamped securely to avoid gaps and ensure a strong bond. Be aware that excess moisture from glue can cause warping, so use products sparingly and make sure that the glue you use is fit for purpose.
Finishing
Plywood edges are often rough and expose the layers of veneer, which can be unsightly. For a polished look, consider edge banding—a thin strip of wood or veneer that adheres to the edge of the plywood. Iron-on edge banding is an easy and effective solution. Alternatively, you can apply a solid wood trim to the edges, which can be glued and nailed in place for a more robust finish.
Plywood surfaces can be rough or have small imperfections. Sanding with a fine-grit sandpaper (220-grit or higher) smooths out the surface and prepares it for finishing. Plywood takes stain and paint well, but to achieve an even finish, apply a wood conditioner.
