Sanding Guide: From Rough to Ready

Sanding is simple in principle but getting good results takes knowledge and technique. Here's how to approach sanding different materials effectively.

Grit Progression

The fundamental principle: start coarse, finish fine. Typical progressions:

• Bare wood: 80 > 120 > 180 > 240
• Between coats: 220-320
• Final finish: 320+

Never skip more than one grit step - scratches from coarse grits show through finer sanding.

Sander Types

Different sanders for different jobs:

• Belt sanders: Aggressive material removal, flattening
• Random orbit sanders: All-purpose, swirl-free finish
• Orbital (sheet) sanders: Light finishing, corners
• Detail sanders: Tight spaces, mouldings
• Drum/spindle sanders: Curves and edges

Technique Matters

Good sanding technique:

• Let the sander do the work - don't press hard
• Move steadily with the grain
• Keep the pad flat to avoid gouges
• Overlap passes for even coverage
• Clean dust regularly to see progress

Hand Sanding

Sometimes hand sanding is better:

• Profiles and mouldings
• Fine finishing work
• Delicate veneers
• Between coats

Use sanding blocks for flat surfaces - finger pressure creates uneven results.

Dust Extraction

Sanding creates fine dust that's bad for lungs and clogs sandpaper. Good extraction:

• Extends sandpaper life
• Improves visibility
• Protects your health
• Keeps workspace cleaner

Sandpaper Quality

Cheap sandpaper is a false economy. Quality abrasives:

• Cut faster
• Last longer
• Leave more consistent scratches
• Don't clog as quickly

Match grit type to material - aluminium oxide for wood, silicon carbide for finishing.
