How to install a Live Edge Slab Countertop
What happens here
Thoroughly sand the live-edge walnut slab to achieve a smooth, blemish-free surface. Start with a belt sander using 50-grit sandpaper to remove any deep mill lines or imperfections. Progress through finer grits using a palm sander: 60-grit, 100-grit, 150-grit, 220-grit, and finally, 3200-grit sandpaper for a polished finish. After each grit, use a dry chamois cloth to meticulously wipe away all dust. Do not use any water, as water can raise the wood grain. For very fine dust removal before the final finish, use a tack cloth.
Goal: Achieve a smooth, dust-free surface on the walnut slab for finishing.
