You CAN sand it! Sanding hard-to-reach areas and what tools to use

Sanding is an essential step in achieving a flawless finish on any surface, but when it comes to contoured surfaces, it can become a bit of a challenge. Contoured surfaces add depth, character, and intricacy to your creations, but they can be tricky to sand uniformly. Fear not! In this guide, we'll explore the techniques, tools, and tips that will help you master the art of sanding contoured surfaces and take your projects to the next level.

Choose the Right Sandpaper Grit

The first step in achieving smooth results is selecting the appropriate sandpaper grit. For initial sanding on contoured surfaces, start with a lower grit (around 80 to 120) to remove any rough spots, imperfections, or tool marks. As you progress, move on to higher grits (180 to 220) for a finer finish. If you're looking for a polished, smooth surface, consider using ultra-fine grits (320 and above) for the final touches.

Embrace Flexible Sanding Tools

Traditional sanding blocks are great for flat surfaces, but for contoured surfaces, flexible sanding tools are your best friends. Foam sanding pads, flexible sanding sponges, and even cloth-backed sandpaper conform to the shape of your workpiece, ensuring consistent sanding across curves and intricate details.

Contoured Sanding Blocks

If your project features consistent curves, consider making custom contoured sanding blocks. Craft these by shaping a piece of scrap wood or foam to match the contour you're working on. Attach the sandpaper to these blocks and enjoy better control and precision while sanding curved surfaces.

Emphasize Patience and Even Pressure 

Achieving uniformity on contoured surfaces requires patience. Apply even pressure while sanding, and avoid pressing too hard on one section, as this can create flat spots. Move the sandpaper along the contours, working with the shape rather than against it.

Mind Your Direction

Sanding against the grain can result in unsightly scratches and blemishes on your workpiece. Always sand in the direction of the grain to maintain a smooth and consistent finish. If your contoured surface has changing grain directions, adjust your sanding technique accordingly.

Hand Sanding vs. Power Sanding

Hand sanding offers a hands-on approach that allows you to feel the contours of the surface better. However, power sanders, such as oscillating spindle sanders or rotary tools with sanding attachments, can speed up the process. Be cautious with power sanders, as they can remove material quickly, potentially altering the shape if not used carefully.

Emphasize Gradual Progression

Sanding contoured surfaces is a journey. Start with coarser grits to tackle initial imperfections and gradually move to finer grits as you refine the surface. Each step prepares the surface for the next, leading to a flawless finish.

Inspect and Repeat

Regularly inspect your work as you sand. Look for any uneven spots, scratches, or remaining imperfections. If necessary, repeat the sanding process with the appropriate grit until you're satisfied with the result.


Sanding contoured surfaces requires a blend of technique, patience, and the right tools. By choosing the correct sandpaper grit, utilizing flexible sanding tools, employing even pressure, and maintaining the proper sanding direction, you can achieve a smooth and consistent finish on your woodworking projects. Whether you're working on furniture, sculptures, or other creative endeavors, mastering the art of sanding contoured surfaces will elevate the quality of your craftsmanship to new heights.
