Applying Synthetic Stucco to a Monolithic Dome Home in Milford, Texas
A 32’ diameter Monolithic Dome Home with a new synthetic stucco roof. This roof will go 10 or 15 years before it will need to be top coated with a simple elastomeric roof coating.

Some friends of Monolithic own a small rental house in Milford, Texas, that was in dire need of some attention to the Airform. The house is about 20 years old, and the Airform has never been coated. Over the years, UV and weather damage has left the polyurethane foam exposed and blistering.
A great way to renovate the exterior of a Monolithic Dome Home like this one is to patch the Airform and install a synthetic stucco coating. A couple of months ago, our team did just that. The following photo journal lays out how we did it.
Once the fabric roof membrane loses its ability to block moisture, foam blisters can sometimes occur. In this project, there were about ten separate blisters. This Airform was left uncoated for far too long.

This is a major foam blister mid-repair. We remove all the loose material from damaged areas before filling them in.

The flashing that once connected the dome roof to the steel carport had badly deteriorated. This will be removed, and new flashing will be installed.

The gray area above the window shows what it looks like after we fill in a badly damaged area. MonoForm primer has been applied over the surface of the Airform in areas where polyurethane foam is exposed. MonoForm is a product Monolithic manufactures and uses on almost all projects. It’s dyed red to mark where it has been applied. MonoForm works well over damaged areas to ensure filler and coatings adhere to the structure.

Severely damaged areas have been patched and filled, and primer has been applied to all areas of exposed foam in preparation for the base coat.

The acrylic concrete base coat can be applied when the dome is ready. A reinforcing mesh is installed mid-spray in areas with large patches.

Once the base coat is complete, the final spray coat can be applied to the dome’s exterior.
