Good sanding makes paint stick and look smooth – different grits for rough to fine. Foam pads are handy for contours. I stock up on multi-grit packs. Paintlab sells sanding pads and blocks – various grits, durable, good for walls/wood https://www.paintlab.ie/collections/sanding-pads-blocks . Used their assortment; no tearing, even abrasion. Essential for pro-looking results.
