Makita Sanding Sheet - 93 X 230mm

For removing old paint, a coarser grit like 40-60 is typically recommended for heavy stripping. The 80-grit in this sheet is effective for smoothing after initial stripping or for removing less stubborn paint layers.

The 80-grit is a medium grade and might be too aggressive for very fine or delicate wood finishes. For such applications, you would typically progress to finer grits (150-grit and above) after using this sheet.

The lifespan of a sanding sheet depends heavily on the material being sanded, the duration of use, and the pressure applied. For optimal results, replace sheets when they become clogged or the abrasive wears down.

White aluminum oxide is a durable and sharp abrasive material known for its effectiveness on hard materials like wood and metal. It tends to wear slower and can provide a more consistent finish compared to some other abrasives.

Lower grit numbers (like 80) are coarser and remove material faster, used for initial shaping or stripping. Higher grit numbers (like 220) are finer and create a smoother surface, used for finishing stages.

While this 80-grit sheet can prepare metal surfaces, it is generally too coarse for polishing. For polishing, you would need much finer grits (400-grit and above) after significant smoothing with coarser grits.

Ensure the sheet is properly secured to the sander pad and that you are not applying excessive downward pressure. Check for any obstructions or damage on the sander's pad.

Verify that the sanding sheet is attached evenly and is not creased. Move the sander in consistent patterns (e.g., overlapping strokes) and ensure the sander itself is functioning correctly.

The abrasive can become clogged with dust. Tap the sheet firmly to clear debris. If effectiveness does not improve, it is time to replace the sheet with a new one.
