Understanding Sandpaper Grits
Sandpaper comes in a variety of grits, indicated by a number. The lower the grit (e.g., 80-grit), the coarser the sandpaper and the faster it removes material. Conversely, higher grit sandpaper (e.g., 220-grit and above) is finer and creates a smoother finish. Here’s a general guideline for sanding grits:
Coarse grits (80-120 grit): Remove heavy material, saw marks, and deep scratches.
Medium grits (150-220 grit): Refine the surface after coarse sanding, and prepare for finer finishing.
Fine grits (320-and-above): Create a very smooth finish for painting, staining, or varnishing.
Choosing the Right Sanding Tool
The best tool for sanding depends on the project at hand. Here are the most common options:
Sanding block: A versatile tool for flat surfaces and controlled sanding. Choose a firm block for coarse sanding and a softer block for finer grits. Ted’s Woodworking offers sanding block plans for customization.
Random orbital sander: Provides a smooth and efficient sanding motion for larger flat surfaces.
Palm sander: Ideal for reaching corners, curves, and smaller detailed areas.
Detail sanding sponges: Conform to various shapes and are great for curved molding or intricate millwork.
Sanding Techniques for Different Projects
Flat surfaces: Use a random orbital sander with even strokes, following the direction of the grain. Overlap your strokes to avoid sanding ridges. For hand sanding, use a sanding block with long, smooth strokes following the grain.
Edges and corners: Employ a palm sander or a sanding block with sharp corners. Tilt the sander slightly to avoid rounding over the edges.
Curved surfaces: Hand sanding with a flexible sanding block or detail sanding sponge is ideal. Conform the sandpaper to the curve and use light, even pressure.
Pro Sanding Tips
Always sand with the grain: This prevents scratches and ensures a smooth finish. You can check the grain direction by gently running your fingers along the wood surface.
Start coarse, progress to fine: Begin with a lower grit sandpaper to remove imperfections, then gradually progress to finer grits for a polished finish.
Use a light touch: Excessive pressure can gouge the wood. Let the sandpaper do the work.
Vacuum or wipe away dust between grits: Dust can clog the sandpaper and hinder a smooth finish.
Clean your sandpaper regularly: Shake or brush away dust to maintain cutting efficiency.
Consider wet sanding: For painted or finished surfaces, use wet/dry sandpaper with light water lubrication to minimize scratches.
Sanding Techniques for Specific Materials
Wood: As discussed above, follow the general sanding guidelines. Ted’s Woodworking plans often include specific sanding recommendations for the chosen wood type.
Paint: Use finer grits (220 and above) with a light touch to avoid sanding through the paint. Wet sanding is a good option here.
Metal: Start with a coarse grit to remove rust or imperfections, then progress to finer grits for a polished finish.
