Stucco is a popular foundation coating choice because it protects against moisture and other environmental elements. It also adds an attractive aesthetic to the home, creating an eye-catching curb appeal. The application process of stuccoing a foundation is not difficult. However, some important steps must be taken to ensure a successful application.
The main advantage of stuccoing a foundation is that it offers an attractive, waterproof, durable finish. Stucco also provides long-term protection from the elements, insects, pests, and other external threats. It can also help insulate your home by reducing heat loss through the foundation walls.
Additionally, stucco requires minimal maintenance over its lifetime and is a relatively inexpensive option for finishing your home’s foundation. You can find step-by-step instructions on how to stucco foundation in this blog article.
Step-by-step Instructions for How to Stucco Foundation
Step 1: Prepare the Foundation
Make sure the foundation is properly prepared before attempting any stucco work. This involves removing all excess dirt, sanding rough spots, and filling in cracks with concrete patches. Install metal lath over the entire surface of the foundation using galvanized nails or screws. Make sure that the lath is securely attached to the foundation.
Step 2: Install the Stucco Base Coat
Mix Portland cement and masonry sand together in a 5-to-1 ratio. Add water slowly, mixing as you go, until the mixture is the consistency of peanut butter. Apply the basecoat to the metal lath using a trowel or hawk, smoothing it out as you go. Make sure that the basecoat is thick enough to cover the lath completely but not so thick that it builds up like a mound.
Step 3: Install the Scratch Coat
Mix Portland cement and masonry sand together in a 4-to-1 ratio. Add water slowly, mixing as you go, until the mixture is the consistency of thin cake batter. Apply the scratch coat to the basecoat using a trowel or hawk, making sure to move in one direction and create grooves as you go. Allow this coat to dry for 24 hours.
Step 4: Install the Brown Coat
Mix Portland cement and masonry sand together in a 3-to-1 ratio. Add water slowly, mixing as you go, until the mixture is the consistency of soft butter. Apply this brown coat to the scratch coat with a trowel or hawk, ensuring no gaps between coats and that the entire surface is covered. Allow this coat to dry for 24 hours.
Step 5: Add Color and Texture
Mix Portland cement, masonry sand, and a color pigment together in a 4 to 1 to 0.5 ratio. This will give the stucco its desired color. Add water slowly, mixing as you go until the mixture is the consistency of soft butter. Apply this finish coat to the brown coat with a trowel or hawk, ensuring no gaps between coats and that the entire surface is covered.
For added texture, use a hand float or brush to create desired patterns in the stucco. Allow this coat to dry for 24 hours before applying the sealer.
Step 6: Apply Sealant
Once the stucco is dry, it should be sealed with an acrylic sealant. This will help protect the stucco from moisture and weather elements. Apply two to three coats of sealant, following the manufacturer’s instructions for application and drying times between coats.
With these six steps, your foundation should now be stuccoed and ready for use. Be sure to read the instructions for any of the tools or materials you use, as safety is always important.

- Make sure the foundation wall is dry before applying stucco.
- Use a garden hose to spray water on the wall and allow it to dry for at least 24 hours.
- Mix the stucco according to the instructions on the packet. The consistency should be thick and creamy but not too runny or lumpy.

How Do You Waterproof Your Foundation After Stuccoing It?
After applying the stucco to your foundation, it’s important to take additional steps to ensure it is properly waterproofed. Waterproofing your foundation helps prevent water from seeping in and causing damage or mold growth. Here are some tips on how to waterproof a stucco foundation:
- Start by applying a layer of the liquid waterproofing membrane. This is available in both acrylic and rubberized coatings that can be sprayed or rolled on your foundation. This will help to protect the stucco from water infiltration and damage.
- You also need to add an additional protective coating. Several different types of sealants can be used, including concrete sealers or elastomeric coatings. This will help to further waterproof your foundation and protect the stucco.
- Finally, you should add a layer of protective coating to the top of your foundation. This is typically done with a cementitious waterproofing system that includes an insulation board and a waterproof membrane. This will help to further protect your stucco from water infiltration and damage.
By following these steps, you can ensure that your foundation is properly waterproofed after applying the stucco. This will help to keep it in good condition for years to come.
How Should You Maintain Your Stuccoed Foundation?
Once your stuccoed foundation has been installed, proper maintenance is key to keeping it looking great and lasting for years. Here are some tips on how to maintain a stuccoed foundation:
- Clean the Surface Regularly. Dirt, dust, and debris can build up on the stucco over time and cause discoloration, so removing any dirt or debris that might be accumulating regularly is important. Clean the stucco using a soft brush and mild detergent solution, then rinse off with clean water.
- Check for Cracks or Damage. Make sure you check your stuccoed foundation from time to time for any signs of cracking, chipping, or other damage. If you notice any such signs, call in a professional to assess and repair the damage as soon as possible.
- Seal it When Necessary. Occasionally, stucco should be resealed with an acrylic sealant to help protect against water infiltration and weathering. How often this is needed depends on the type of stucco used, so refer to your manufacturer’s instructions.
By following these steps, you can ensure that your stuccoed foundation looks good and lasts many years.
