Things You'll Need:
- Sandpaper
- Primer
- Joint compound
- Wide putty knife (8-inch blade or wider)
- Sponge
- Safety goggles or glasses
- Dust mask
-
Step 1
Sand off all high spots on the wall if the texture is deep. Wipe off all dust residue with a damp, rough cloth when finished.
-
Step 2
Apply a primer to the wall unless you painted with a flat paint. The joint compound you are using to smooth the wall needs a good finish to adhere to. Flat paint or a primed surface is best.
-
Step 3
Purchase joint compound from any hardware store or home improvement center. This can come in large 5- to 10-gallon buckets. Measure the wall you are smoothing, and then buy the amount of compound you need.
-
Step 4
Spread the joint compound across the wall using a wide putty knife. Apply a few coats, as necessary. Don't sand between coats, but knock off any high spots with a dry putty knife after the compound dries.
-
Step 5
Smooth the wall with sandpaper after the final application of joint compound. Fill in any spots, if necessary, and sand those when dried. Wipe wall with a damp sponge when finished.
