Smooth and Finish Plastic Models

More Flexible than rigid sanding tools. The range covers grits from 180 through 3000.

These sanding sponge sheets measure 114 × 140 mm (approximately 4.5 × 5.5 in) and can be cut into smaller pieces as needed. The sanding cloths measure 170 × 130 mm (approximately 6.7 × 5.1 in) and are particularly useful on curved surfaces such as model car bodies.

Both product styles can be used for wet or dry sanding. The comparison chart makes it easier to identify the appropriate grit, product number, size, and recommended use for each stage of a modelling project.

Frequently Asked Questions

What Tamiya sanding grit should I use for removing material or heavy seam lines?

Lower grits remove material more aggressively. The 180, 240, and 320 grit sanding sponge sheets are useful for initial shaping, removing prominent seams, and cleaning up rough areas before moving to finer grits.

What grit is best for preparing a model before painting?

The 400 to 1000 grit range is useful for general surface cleanup and smoothing primer, putty, or plastic before paint. Progressively moving through the grits helps reduce scratches left by coarser sanding.

What should I use for very fine finishing or polishing preparation?

The 1500, 2000, and 3000 grit products are designed for increasingly fine surface refinement. The 3000-grit sponge is especially useful for ultra-fine wet sanding before polishing.

What is the difference between Tamiya sanding sponges and sanding cloths?

Sanding sponges have a flexible sponge backing, while the softer sanding cloths are particularly well suited to curved and complex surfaces. Tamiya sanding cloths are available from 600 to 3000 grit and can be used wet or dry.
