Abrasive mesh 115×280 mm grit 300

Abrasive mesh 115x280 mm grit P300 - for final sanding of skim coat before painting. Grit 300 is fine: removes scratches left by coarser grits, smooths the surface to paint-ready. The last pass before rolling.

115x280 mm is the standard size for hand sanding blocks and orbital sanders. Mesh structure lets dust fall through the holes, keeping the abrasive from clogging. Matters especially with gypsum fillers - they load up plain sandpaper fast.

For finishing skim like Knauf HP Finish or similar - P300 is the right grit. Coarser and you get scratches showing under paint. Finer and you're working for nothing.
