Tools You Will Need

To remove lath and plaster ceilings and walls, all you need are a few tools that you may already have in your own toolkit.

  • Gauging brick/trowel
  • Working platform and/or sturdy stepladders
  • Claw hammer (or any lightweight hammer may do)
  • Crowbar/ pry bar/wrecking bar
  • Pickaxe (if you do not have one of these, you can manage but they are great for getting old laths down)
  • Items to clean up with: Broom, dustpan, shovel, shop vac/vacuum cleaner

You may also need electrical screwdrivers to remove old fittings, rubble sacks and dust protection like dust sheets.

How to Remove Lath and Plaster

To remove lath and plaster, there are essentially four steps. There are five if you need to prep the area by setting out dust sheets and removing furniture.

  1. Remove the plaster with a hammer and stout trowel. Work in front of yourself by tapping the plasterwork to break it up. If it does not drop away, keep tapping and use the claw hammer or trowel to lever the plasterwork off. If you are working on a poor ceiling or wall, you can slide the trowel under the plasterwork and pull large pieces away.
  2. Clear debris away at this stage. You do not have to clean up entirely but get the big chunks out of the way.
  3. Remove the laths with a pickaxe. Slide the blade through a few of the laths and position the pickaxe at the bottom of a joist. Lever large sections of lath down.
  4. Finally, remove the nails that were holding the laths up. This is tedious but it is imperative that you do this! Otherwise, you could hit a nail while putting up new boarding and it can be a pain to deal with.
