How to Stucco a Foundation


Stucco is a simple coating composed of an aggregate and binder that applies easily and spruces up otherwise plain-looking surfaces. The concrete of a foundation is functional but hardly appealing. By stuccoing the foundation, you can enliven the space and bring a certain rustic appeal to your home. Even for those who have never applied stucco, the project is straightforward and can be finished in just a few days of work.

Things You'll Need

  • Wire-bristled brush
  • Pump sprayer
  • Concrete degreaser
  • Nylon-bristled brush
  • Garden hose
  • Concrete bonding liquid
  • Paintbrush
  • Paint roller
  • Wheelbarrow
  • Powdered stucco mix
  • Water
  • Shovel
  • Stucco hawk
  • Steel trowel
  • Rubber float
  • Pull all debris off the foundation by running a wire-bristled brush over the entire surface.

  • Fill the tank of a pump sprayer with a concrete degreaser and apply it to the foundation where you intend to apply the stucco finish. The degreaser will break down any residue on the surface, allowing the stucco to properly adhere.

  • Scrub the degreaser into the foundation with a nylon-bristled brush. Use short, circular movements with the brush to pull all residue off the foundation.

  • Spray the foundation with a garden hose to remove the degreaser.

  • Wait at least 24 hours for the concrete of the foundation to dry. Do not advance with the project unless the foundation is dry to the touch.

  • Apply a thin, even layer of concrete bonding liquid onto the foundation. A paintbrush or paint roller will work effectively for the application. Allow the liquid to partly dry for 13 to 15 minutes so it feels tacky.

  • Mix water and the stucco powder in a wheelbarrow with a shovel. Use the recommended ratio of water to stucco mix as indicated on the instructions..

  • Grab a stucco hawk with one hand and scoop some stucco onto it with a trowel in the other hand. The hawk will allow you to hold a good portion of stucco so you don't have to continually go back to the wheelbarrow.

  • Scoop stucco from the hawk with the trowel apply it to the base of the foundation wall with an upward stroke. Hold the trowel at a 45 degree angle to the wall as you apply the stucco. Work from the base of the wall to the top, being sure to make a large sweep with the trowel and keeping the stucco to a 1/2-inch thickness. Wait for the finish to dry for approximately 20 minutes.

  • Soak a rubber float in water and run it over the stucco with long sweeping strokes. Make sure you apply little pressure to the stucco. You do not want to redistribute the stucco but rather smooth the surface.
