Model sandpaper sheets & sanding sponges

Model sandpaper sheets & sanding sponges

Great finishes start with consistent prep. Our selection of model sandpaper gives you predictable cutting power from first seam removal to ultra-fine finishing. You’ll find flexible sponge paper for curves, pre-cut sheets for quick changes, and adhesive kits for custom blocks—everything you need to step through grits methodically without rounding edges or scratching clear parts. When you want smooth paint, sharp decals, and fewer re-sprays, model sandpaper is the tool that gets you there.

What’s in this collection

• Sponge paper and sanding sponges that conform to fuselages, car bodies, cowlings, and figure capes to avoid flat spots while blending transitions.
• Pre-cut sandpaper sheets (P240–P2000) sized for repeatable strokes over sprue nubs, seams, and filled joints.
• Adhesive abrasive kits to mount sheets on blocks or custom sticks for perfectly flat removal.
• Wet/dry options that resist clogging and keep plastics cool during longer sanding sessions.

Each item complements the next so you can progress through grits efficiently and arrive at a uniform, paint-ready surface with your model sandpaper workflow.

Why these abrasives improve results

Generic hardware paper loads quickly, sheds grit, and leaves deep scratches. Purpose-made modeling abrasives are graded accurately for controlled scratch patterns across the full range.

• Reliable grit steps erase previous scratches cleanly from P240 through P2000.
• Durable backings and binders resist tearing—wet or dry.
• Task-specific formats: sheets true up flat joints; sponges float across curves; adhesive pieces shape to any need.
• Paint-ready finishes help primers, acrylics, enamels, and lacquers level smoothly.

Pro workflow: from seam to shine

• Start with P240–P400 on a hard block to level sprue gates and filled seams.
• Blend at P600–P800 using sponge paper to follow compound curves.
• Refine with P1000–P1500 in single-direction passes so remaining scratches are easy to see.
• Finish at P2000 (or finer) before primer on gloss subjects; wet-sand clear parts and then polish.
• Between steps, sweep residue with a dust remover brush and rinse lightly so debris doesn’t telegraph through paint.

Tips to protect detail

• Mask raised rivets and photo-etch while sanding nearby.
• Use short, controlled strokes along panel lines to avoid rounding edges.
• Replace worn pieces early—dull abrasives burnish rather than cut.
• Keep separate sets for plastic and resin to prevent contamination.
• Work under raking light to spot remaining seams before moving up a grit.

With the right model sandpaper, prep becomes faster and more consistent—leading to smoother coats, sharper decals, and professional results on every build.
