How to Remove Fake Brick From Drywall

Insert a thick-bladed drywall knife under the brick to pry it away. A 3- or 4-inch drywall knife should do, but the size isn't as important as the thickness -- you don't want the knife to break while you are using it. Be as gentle as possible to avoid damaging the drywall underneath the brick.

Use a hammer and chisel to shatter the brick if it proves too difficult to pry away. A crowbar is also an effective choice. Note that both of these methods likely will damage the drywall underneath, so only use them as a last resort.

Scrape the remaining adhesive off the wall with the drywall knife. If the paper surface of the drywall tears, use a utility knife to cut a circle around the damaged area to limit how much paper will rip away.

Remove all loose bits of material from the wall to prepare the surface for repairs. The goal is to create a stable subsurface to which the joint compound can adhere.

Coat the area with a thick layer of ready-mixed joint compound. Use a 12-inch drywall knife to cover a large area at once. Leave as few ridges and lines as possible, and let the joint compound dry for at least 24 hours.

Sand the joint compound smooth with 100-grit sandpaper. If the area still looks rough, apply another coat of joint compound, let it dry and sand it again. It might take several coats before the area looks smooth.
