How to Finish Plywood Edge

Plywood is a versatile building material that is commonly used in construction, furniture making, and DIY projects. It consists of thin layers of wood veneer glued together to form a strong and durable board. One of the challenges when working with plywood is finishing the edges to give it a clean and professional look.

In this guide, we will discuss different methods on how to finish plywood edge, from simple and budget-friendly options to more advanced techniques.

Necessary Items

Before we dive into the methods, you will need to gather some essential items to prepare for finishing your plywood edges. These include:

• Sandpaper or sanding block (various grits)
• Wood filler or putty
• Paintbrush or roller
• Primer and paint (if painting)
• Veneer edge banding (if using the iron-on method)
• Edge banding trimmer or router (if using the iron-on method)
• Veneer edge sealer and edge smoothing tool (if using the veneer tape method)

13 Steps on How to Finish Plywood Edge

Step 1: Sanding

Sanding is the most basic and budget-friendly way to finish plywood edges. It involves smoothing out rough edges and imperfections with sandpaper or a sanding block.  Start with a coarse grit sandpaper (around 80-100) to remove any large splinters or bumps. Then, gradually work your way up to finer grits (200-400) for a smooth finish.

Step 2: Wood Filler

If your plywood edges have noticeable gaps or holes, you can use wood filler or putty to fill them in. Apply the filler with a putty knife, then sand it down once dry to create a smooth surface. And don’t worry about the color of the filler, as it can be painted over later.

Step 3: Prime (optional)

If you plan to paint your plywood, it’s recommended to prime the edges first. This will ensure that the paint adheres well and creates a smooth finish. Use a brush or roller to apply primer evenly and let it dry completely before moving

Step 4: Paint

If you plan on painting your plywood project, you can simply apply primer and paint to the edges for a clean finish. Make sure to use painter’s tape or a steady hand to avoid getting paint on the visible parts of your project.

Step 5: Iron-On Edge Banding

Iron-on edge banding is a popular method for finishing plywood edges as it gives a seamless and professional look. It involves applying heat to adhesive-lined veneer strips that are then pressed onto the edges of the plywood. First, cut the banding to size and apply it to the edge. Then, use an iron to heat and activate the adhesive. Finally, use a trimmer or router to cut off any excess banding.

Step 6: T-Molding

T-molding is another method for finishing plywood edges, commonly used in flooring and furniture making. It involves inserting a plastic or wood strip into a groove cut into the edge of the plywood. This creates a durable and smooth edge that can also add a decorative touch to your project.

Step 7: Veneer Tape

Veneer tape is a thin strip of real wood veneer with an adhesive backing. It’s an excellent alternative to iron-on banding for those who don’t have access to iron or prefer a more natural look. To use, simply cut the tape to size and apply it to the edge, then use a smoothing tool to ensure a tight bond.

Step 8: Veneer Edge Sealer

For those using veneer tape, it’s recommended to seal the edges with a veneer edge sealer. This helps prevent the tape from peeling or lifting over time. Apply the sealer with a brush, then use the smoothing tool to ensure a smooth and even finish.

Step 9: Router

Using a router is a more advanced technique for finishing plywood edges, but it can create beautiful and precise results. First, choose a router bit designed for edge trimming or flush trimming. Then, use the router to trim off any imperfections or excess material from the edge of the plywood.

Step 10: Beading

Adding a beaded edge to your plywood is another option for a decorative finish. This involves using a router with a beading bit to create a rounded edge along the perimeter of the plywood. This method works best for thinner plywood boards.

Step 11: Mitered Edge Trim

Mitering is another advanced technique for finishing plywood edges. It involves cutting a 45-degree angle on the edge of the plywood and attaching a trim piece to create a clean and precise finish. This method is commonly used in furniture making.

Step 12: Edge Painting

For a unique and modern look, you can also consider painting the edges of your plywood project. Use painter’s tape to create clean lines, then apply paint in a contrasting color to the visible edge of the plywood.

Step 13: Varnish or Sealant (optional)

Finally, if you want to protect your plywood edges and add a glossy finish, you can apply varnish or sealant. This is optional but recommended for outdoor projects or those that will be heavily used.

Finishing plywood edges may seem like a daunting task, but with the right tools and techniques, you can achieve a professional and polished look. Choose the method that best suits your project and budget, and don’t be afraid to experiment with different finishes for unique results.
