Coarse-grained sandpaper, designed for YT-82330 trowel and other devices on the market.

Using sandpaper for the trowel allows you to grind polystyrene boards glued to the wall to level the surface before applying thin-coat plaster. Troweling off wallpaper or other wall coverings (oil paint, dysperbit, vinyl tile adhesives) greatly speeds up the work and reduces the amount of force needed to prepare the substrate before applying new layers or leveling the base coats.
