How to Sand Wood Veneer to Level Filler

To sand wood veneer and reach the goal of level filler, focus on a steady grit progression and even pressure. These silicon carbide sheets are built for wet or dry use, so you can choose cleaner wet sanding or quicker dry sanding based on the stage.

Why Sanding Matters

Sanding is how you control surface flatness and scratch depth. A consistent pattern improves adhesion and helps your final finish look uniform.

Tools

• Sanding block or hand pad
• Vacuum/brush for dust removal
• Microfiber cloth or tack cloth
• Optional: spray bottle + clean water for wet sanding
• Optional: painter’s tape for protecting edges

Recommended Grit Sequence

• 80 grit
• 120 grit
• 150 grit
• 180 grit

Step-by-Step

1. Clean the surface. Remove residue so the abrasive cuts evenly.
2. Level and blend. Start with 80 Grit (100) to remove highs and smooth transitions.
3. Refine scratches. Move to 120 Grit (100) until the previous grit marks are gone.
4. Finish prep. Use 150 Grit (100) for a uniform scratch pattern appropriate for the next step.
5. Inspect closely. Angled light will reveal deep lines and low spots.
6. Final cleanup. Vacuum and wipe (and dry fully if wet sanding) before finishing.

Special Cases

Clogging: Wet sanding helps reduce loading; rinse sheets and wipe slurry often.
Edges: Use lighter pressure to avoid rounding.
Between coats: Use the finest grit and sand only until the sheen is uniformly dull.

Pro Tips

• Don’t skip large grit jumps—each grit removes the scratch pattern from the one before it.
• Overlap passes and keep pressure light.
• Change direction slightly with each grit to spot missed scratches.
• Replace sheets when they stop cutting; fresh abrasive saves time.

Aftercare

• Remove all dust before coating.
• Store sheets flat and dry.
• If wet sanded, allow full drying time before primer/paint.

FAQs

• Can I use these wet? Yes—silicon carbide sheets are designed for wet or dry use.
• When should I move to the next grit? When the scratch pattern is consistent and the previous grit scratches are gone.
• Do I need a sanding block? For flat surfaces, a block helps prevent finger grooves and uneven spots.

Watch & Learn

Pay attention to the surface checks between grits—catching deep scratches early prevents rework later.

For a consistent finish, follow the grit sequence and keep strokes even—start with 80 Grit (100) and work upward to a smoother surface.
