SIA Abrasives - Abrasive fleece

SIA sanding fleece is a high-quality, flexible abrasive for professional surface finishing in the automotive and painting sector. It is used for matting, cleaning, and preparing paint, filler, and metal surfaces, ensuring an even, adhesive surface before further coating.

Classification is done using color codes, which roughly correspond to a comparable sandpaper grit range (P-value):

Red (SIA medium / Very Fine)
corresponds to approx. P360–P400
Standard in paint application. Suitable for sanding fillers, old paint, and plastic parts before painting. Ensures good adhesion of subsequent layers.

Yellow (SIA fine / Ultra Fine depending on type)
corresponds to approx. P800–P1000
For very fine matting of paint and clear coat surfaces. Ideal for blending, transitions, and delicate surfaces with low material removal.

Grey (SIA ultra fine / Micro Fine)
corresponds to approx. P1200–P1500+
For finishing work, intermediate sanding, and extremely fine matting. Perfect for preparing clear coat or high-gloss surfaces without visible sanding marks.

Available in round and rectangular shapes.
