demolishing a cinder block wall

Step 1: Confirm That the Wall Is Not Load-Bearing

If the wall isn't load-bearing and can be removed safely, check for electrical wires and plumbing in the wall. Turn off the breaker and take care to move wires out of the way before starting on the wall.

Step 2: Prepare the Area

Remove furniture and stored items, cover the surrounding area with a drop cloth and hang plastic sheeting from the ceiling to keep your clean-up area contained.

When using a sledgehammer, make sure it isn't too heavy for you to use effectively. If the hammer is too heavy, it will cause you to become exhausted quickly and slow down the process. Check your swing radius to make sure you have enough space on all sides to use the hammer safely.

Step 3: Demolishing the Wall With a Sledgehammer

First use a prybar to remove the drywall from furring strips; then begin demolishing the wall using the sledgehammer to remove the cinder block surface underneath.

It's best to have more than one person for this project. For safety's sake, notice those working around you and make sure they are keeping an eye out for you.

Continue to remove debris as you go along. Having to navigate around piles of debris can be tedious, time-consuming and dangerous. Exposed nails, screws, metal, wood, and large pieces of debris can create a very hazardous situation.

Step 4: Patch the Adjacent Wall(s)

Once the wall has been demolished, the adjacent wall(s) need to be patched and smoothed. Cover the seams with drywall tape and then use a putty knife or a drywall knife to apply joint compound. Feather the joint compound away from the seams as you apply it.

Use a small orbital sander to smooth the surface and prepare it for painting. Then remove any residue, prime and paint.
