Use the correct grit sandpaper
Wrong grit can leave grooves in the material.
• Coarse grits (lower numbers) remove material quickly but can leave deep grooves.
• Finer grits (higher numbers) create a smoother finish—choose the right grit for your task.
Check belt tension
Incorrect tension can cause uneven sanding and grooves.
• Refer to your sander’s manual for proper belt tensioning instructions.
Avoid excessive pressure
Pressing too hard can dig into the material and create grooves.
• Let the weight of the sander do the work—guide it evenly across the surface.
Apply even pressure
Uneven pressure can result in grooves.
• Distribute pressure evenly across the sanding surface.
Ensure belt alignment
A misaligned belt can create grooves.
• Check that the belt is centred on the drum and adjust as per the manufacturer’s instructions.
Inspect belt condition
A worn or damaged belt will not sand evenly.
• Replace the belt if you notice wear, damage, or uneven sanding.
Check for belt contamination
Debris or adhesive residue can cause uneven sanding.
• Clean or replace the belt if contaminated.
Remove dust and debris
Dust buildup can interfere with sanding and cause grooves.
• Ensure the dust collection system is working and the sanding surface is clean.
Consider starting with coarser grit
Hardwoods or irregular grain patterns may require leveling first.
• Begin with a coarser grit, then move to finer grits for a smooth finish.
