How to Remove Dried Spackling Off Walls

Spackling compound allows you to fix holes in walls and prepares the walls for priming and painting. This gypsum-powder joint compound is a staple of home-improvement projects, but filling in holes with spackling and a putty knife isn't the end of the job. Spackling leaves a rough finish on walls that has to be sanded down.

  • Narrow-blade putty knife

Instructions

    • 1

      Put on a dust mask to avoid inhaling small particles.

    • 2

      Chip off large chunks of spackling with a small metal putty knife. Scrape the blade of the knife gently against any ridges to remove them.

    • 3

      Sand the remaining spackling in a circular motion with a piece of 120- or 150-grit sandpaper. Use a hand sander to make the job go faster.

    • 4

      Wipe the wall with a damp sponge to remove leftover dust. Sweep up any dust on the floor with a broom.

    • 5

      Prime the spot where the spackling was with latex primer before painting over it. Paint the primer onto the spot with a bristle or sponge brush.
