What type of sander is best for plywood?
When working with plywood, choosing the right sander is crucial for achieving a smooth, professional finish without damaging the delicate veneer. Plywood consists of thin layers of wood glued together, making it prone to splintering or over-sanding if the wrong tool is used. Here are the best sanders for plywood and their advantages.
1. Random Orbital Sander
The random orbital sander is one of the best choices for plywood. It combines spinning and oscillating movements, reducing the risk of swirl marks while providing an even finish. Since it doesn’t sand in a fixed pattern, it minimizes the chance of damaging the plywood’s top layer. Use 120- to 220-grit sandpaper for the best results.
2. Sheet Sander (Finish Sander)
A sheet sander (also called a finish sander) is ideal for fine sanding plywood. It uses a back-and-forth motion, making it less aggressive than belt sanders. This type of sander is perfect for smoothing edges and preparing plywood for painting or staining.
3. Detail Sander
For tight corners and edges, a detail sander is highly effective. Its small triangular or pointed pad allows for precision work, ensuring that no area is left uneven.
Sanders to Avoid
Belt Sanders – Too aggressive for plywood and can quickly remove too much material.
Coarse-Grit Sandpaper – Can tear the veneer; always start with a finer grit (150+) and work gradually.
Final Tips
Always sand with the grain to prevent scratches.
Use a dust collection system to keep the surface clean.
Finish with a higher grit (220 or higher) for a polished look.
By selecting the right sander and technique, you can achieve a flawless finish on plywood for any project.
