eQualle Sandpaper Sheets for Automotive Headliner Board Repair (80–320 Grit Guide)

When restoring or replacing a sagging headliner, the headliner board must be properly prepped before applying new adhesive and fabric. eQualle 9x11 inch Wet/Dry Sandpaper Sheets provide the grit sequence needed to clean, smooth, and ready the surface for a long-lasting bond.

Why Sanding Matters for Headliner Repair

Headliner boards often have old adhesive residue, foam, or uneven surfaces. Sanding ensures these are removed, leaving a smooth base for spray adhesive. Without sanding, the new headliner fabric may bubble, peel, or fail prematurely.

Tools You’ll Need

• Sanding block or orbital sander
• Vacuum or tack cloth
• Spray adhesive
• New headliner fabric
• eQualle Wet/Dry Sandpaper Sheets

Best Sandpaper Grits for Headliner Board

• 80 Grit (25-pack) — Removes stubborn foam and adhesive buildup.
• 120 Grit (50-pack) — Smooths rough board surfaces after coarse sanding.
• 220 Grit (100-pack) — Refines the surface for even adhesive application.
• 320 Grit (25-pack) — Final sanding step before applying spray adhesive.

Step-by-Step: Preparing a Headliner Board

1. Remove old fabric. Peel off the sagging headliner carefully, exposing the foam and board.
2. Sand with 80 grit. Remove deteriorated foam and adhesive completely.
3. Switch to 120 grit. Smooth the board surface to eliminate coarse scratches.
4. Refine with 220 grit. Create a uniform texture for better adhesive bonding.
5. Finish with 320 grit. Lightly sand for a smooth, even surface.
6. Clean thoroughly. Vacuum or wipe with a tack cloth to remove dust.
7. Apply new fabric. Spray adhesive evenly and attach the new headliner fabric.

Special Cases

For fiberglass headliner boards, avoid coarse grits below 80 to prevent gouging. For cardboard-style boards, use light pressure with finer grits to maintain board integrity.

Pro Tips

• Work in a ventilated area when sanding foam and adhesive residues.
• Always let the board dry fully before applying spray adhesive.
• Test adhesive coverage on a small section before committing.

Aftercare

• Allow adhesive to cure fully before reinstalling the headliner.
• Avoid direct sun exposure during curing for best results.
• Inspect periodically for bubbles and reapply adhesive if necessary.

FAQs

• Do I need to sand every headliner board? Yes, sanding ensures proper adhesion for the new fabric.
• Can I skip to 220 grit directly? Only if the old foam and adhesive are minimal.
• Will sanding damage the board? Not if done with light pressure and correct grits.
