Enhance the exterior of your foundation with a basic parge application and reap the benefits of a protected foundation.
Things You Will Need
-
Scrape off loose bits of mortar from the foundation wall with a drywall knife.
-
Scrub down the wall to remove additional loose bits and debris from the foundation with a stiff bristled wire brush.
-
Spray a fine mist of water onto the foundation so that it is damp to the touch.
-
Mix together one part Portland cement, 1/2 part hydrated lime and three parts washed sand in a wheelbarrow.
-
Slowly add water to the dry materials in the wheelbarrow and stir together with a shovel. Stop once the material has the consistency of peanut butter.
-
Scoop the mixture onto a flat trowel and spread it onto the base of the wall with upward strokes. Continue parging the foundation until it is covered with an even coat. Aim for a thickness of 1/4 inch.
-
Run a damp broom over the recently applied coating. Allow it to dry for 24 hours.
-
Dampen the foundation with a mist of water, then apply a second coating using the same process as the previous day. The second coating will dry in 24 hours.
