How to Use a Graphite Coated Canvas for Sanding

Quick Answer

Use a graphite coated canvas as a platen liner under your sanding belt to reduce friction and heat, helping the belt run cooler and last longer. Install it smoothly, secure it properly, and replace it when worn.

Step-by-Step Installation and Use

1. Prepare the Platen: Clean the platen surface thoroughly to remove dust, old adhesive, or debris. A clean surface ensures the canvas adheres evenly and prevents wrinkles that can cause uneven sanding. Check that the platen is completely dry before applying the canvas.
2. Cut the Canvas to Size: Measure the platen dimensions and cut the graphite coated canvas slightly larger than the platen. Trim it to fit precisely, leaving no overhang that could catch on the belt. Use sharp scissors for a clean cut. A precise fit is essential; overhang can cause the canvas to peel or interfere with belt movement.
3. Attach the Canvas: Peel off the backing (if adhesive-backed) or apply a thin layer of contact adhesive to the platen. Press the canvas onto the platen, starting from one edge and smoothing outward to eliminate air bubbles. Ensure it lies flat and smooth. Avoid creases or bubbles—they create high spots that can cause uneven sanding or premature wear.
4. Install the Sanding Belt: Mount the sanding belt over the platen with the canvas in place. Ensure the belt tracks correctly and moves freely. The graphite coating should not impede belt movement; it should feel smooth. If the belt drags or makes noise, check for misalignment or excess adhesive residue.
5. Test and Monitor: Run the sander briefly without workpiece contact to confirm smooth operation. Then perform a test sanding on a scrap piece. Monitor belt temperature and finish quality. If the belt runs hot or the finish degrades, inspect the canvas for wear or damage. Replace the canvas when you notice visible wear, tears, or a loss of lubricity—typically after several hours of heavy use.
