Things You'll Need:
- Portland cement
- Sand
- Water
- Trowel
- Towel
-
Step 1
First throughly clean the wall you are about to parge. Be careful to remove any paint dirt or concrete chips. A power washer can be handy but a good wire brush works as well.
-
Step 2
Once the wall is clean it's time to mix the parging mixture. Combine an 80lb bag of Portland cement with 65-70lbs of sifted sand. Once you have mixed these together and the parge is homogeneous begin adding water.
-
Step 3
Gradually add water to the parging mixture until no more will easily absorb in to it.
-
Step 4
Before you parge a wall you will want to do two things. First Cover the floor so that it is protected from any stray parging mix. Second take a wet towel and wipe down the wall. This prevents it from sucking moisure out of the parging mix before it can set properly.
-
Step 5
Next using a wet trowel begin to parge the wall by smearing the parging mixture on with fluid circular motions and a steady pressure. Overlap passes to give a nice textured appearance. Start in a corner.
