Tips for Cutting and Finishing Plywood for Professional Results

Cutting and finishing plywood can be challenging, even for seasoned woodworkers. 

For example, what do you do when your freshly-cut plywood edges fray or when the finish of your project turns out blotchy? 

This often happens when incorrect techniques or unsuitable tools are used, compromising the aesthetics and affecting the project's structural integrity. 

Fortunately, you can overcome these issues with the right tips and techniques. This guide will provide actionable advice on cutting and finishing plywood for professional results, enabling you to work confidently and precisely every time.


Understanding Plywood

What is plywood? Plywood is an engineered wood product made by glueing several thin layers of wood veneer, or 'plies'. Additionally, the alternating grain direction of the layers gives plywood its strength and stability. 


Choosing the Right Plywood

The first step towards achieving professional results is choosing the right plywood for your project. 

Plywood comes in various grades, with A-grade being the highest quality, featuring a smooth, sanded surface with minimal defects. Likewise, A-grade plywood is the best choice for projects requiring a high-quality finish, such as furniture or cabinetry.


Cutting Plywood: Tips and Techniques

Use the Right Tools

The key to a clean cut is using the right tools. A circular or table saw with a sharp blade is ideal for cutting plywood. Moreover, a blade with more teeth produces a smoother cut, reducing tear-out chances.


Support the Plywood

When cutting plywood, ensure it's adequately supported. This prevents the plywood from bending or moving during the cut, which can lead to inaccuracies or damage.


Score the Cut Line

Scoring the cut line before cutting can significantly reduce tear-out. So use a utility knife to score along the cut line, then cut along the scored line.


Use a Zero-Clearance Insert

A zero-clearance insert is a plate that fits around the saw blade, supporting the plywood and reducing tear-out. This is particularly useful when cutting thin or delicate plywood.


Finishing Plywood: Tips and Techniques


Sanding is a crucial step in achieving a professional finish. You should start with a coarse-grit sandpaper to remove any rough spots or defects, then gradually move to finer grits for a smooth finish. Remember, always sand in the direction of the grain to avoid scratches.



Plywood often has voids or knots that must be filled for a smooth finish. For best results, use a high-quality wood filler that matches the colour of the plywood. Apply the filler, let it dry, then sand it smooth.



Sealing the plywood helps to prevent moisture absorption and enhances the wood's natural beauty. Make sure you use a high-quality wood sealer, applying it with a brush or a cloth. Allow the sealer to dry, then lightly sand the surface before adding coats.


Use a Top Coat

The final step in finishing plywood is applying a top coat. Depending on the desired look and durability, this can be a varnish, lacquer, or polyurethane. Most importantly, apply the top coat evenly, following the grain of the wood. Once applied, allow it to dry, then lightly sand between coats for a smooth, professional finish.


Advanced Cutting Techniques: The Jigsaw & Router

Plywood isn't only about straight lines and sharp corners. Creative projects often demand curves, intricate shapes, and clean edges, requiring additional tools and techniques. 

For example, jigsaw cutting is ideal when you're working on a project that demands curves or irregular cuts. Jigsaws allow you to easily navigate tight turns or complex shapes, but a blade with a high tooth count is essential for a smoother finish.

For creating clean, precise edges, a router comes into play. Routers can round over edges, make decorative cuts, or create dados and rabbets. Moreover, with an assortment of bits available, the router provides a new level of creativity and finish to your plywood projects.


Keeping Plywood Edges Sharp: Use of Edge Banding

Raw plywood edges reveal the core layers and can look unfinished in a project that otherwise boasts a professional look. This is where edge banding steps in. 

Edge banding is a thin strip of veneer that can be ironed or glued onto the edges of your plywood. This hides the layers and provides a clean, solid-wood appearance.


Handling Plywood Tear-Out: Backer Boards

Tear-out can ruin an otherwise perfect cut. We've already touched on scoring the cut line and using a zero-clearance insert to reduce this issue. However, a backer board can provide assurance when dealing with delicate or extremely thin plywood. 

Backer boards, positioned behind the plywood during the cut, support the wood fibres and prevent them from tearing or chipping.


Final Touches: Staining Plywood

Staining your plywood project can give it a rich, custom appearance while highlighting the wood's natural grain pattern. However, plywood often absorbs stain unevenly, leading to a blotchy finish. To avoid this, apply a pre-stain conditioner before staining. It'll help absorb the stain evenly, creating a more consistent and aesthetically pleasing colour.


Maintaining Your Tools: Key to Consistent Results

It's essential to remember that your tools need maintenance to ensure their longevity and performance. So, regularly clean and oil your tools, sharpen or replace your blades, and properly calibrate your machines. This will ensure they operate at their best and give you consistent, professional-grade results.


Final Thoughts: Mastering Patience and Precision

Achieving a professional finish with plywood demands skills, techniques, and a deep understanding of the material. It's about recognising the grain direction, knowing how the wood will react to a certain cut, or understanding how different finishes can enhance or mute its natural appearance.

Remember, every project is a learning opportunity. Sometimes, you may encounter warping or unexpected knots, or your cuts might not turn out as planned. But embrace these as part of the woodworking journey. Ultimately, patience, precision, and the courage to experiment will hone your skills and open the door to endless creative possibilities.
