STARCKE 991A Softflex Silicon Carbide Waterproof (P400–P3000)

The STARCKE 991A Softflex is a high-quality, waterproof abrasive paper with a flexible latex paper backing and silicon carbide grit. It is specifically developed for wet and dry sanding and is used in the automotive and painting sectors for very fine and controlled surface finishing.

Thanks to its soft and flexible backing structure, the abrasive paper adapts very well to curves, edges, and delicate surfaces. This results in an even sanding pattern with a low risk of deep scratches or sanding through.

The wide grit range from P400 to P3000 covers the complete fine sanding and finishing range:

• P400–P800: Fine sanding of filler, primer, and preparation for paint
• P1000–P2000: Intermediate sanding of paint and clear coat layers
• P2500–P3000: Very fine finishing work, removal of dust inclusions, and preparation for high-gloss polishing

The waterproof design reduces clogging of the abrasive, resulting in longer tool life and a more consistent sanding pattern. At the same time, wet sanding allows for low-dust and very controlled processing of painted surfaces.

The material is ideal for professional painting, smart repair, vehicle detailing, and all applications where a particularly smooth and high-quality surface is desired.
