Midwest dome home finishes recoating

Monolithic Domes, just like any other building, require upkeep to remain functional. The Monolithic Dome home in Dighton, Kansas known as the Muddpuddle Dome On The Prairie was recently recoated to preserve the dome.

The home suffered damage from a hail storm in 2016, creating the need for a recoating. More rain and wind this year created further damage to the home, tearing off large pieces of the skin and exposing the polyurethane foam.

“The skin broke down and became unstable,” stated homeowner Kay Mudd.

The project was completed by Dome and Roofing Solutions, a company founded by Lars Benson that recoats domes and large metal structures. Their work was completed at the beginning of May, finishing in just a few days. The company was chosen after a bid was presented to the owners by a referral from the Monolithic Dome Institute.

“We felt like they were qualified to do a good job,” Kay said. Their insurance company did pay for the claim, she said, after their deductible.

To apply the recoat, the company used liquid EPDM rubber sprayed at 20 millimeters thick. “The product is spray applied so therefore it is also seamless,” stated national sales manager Lloyd Benson. The homeowners should be able to rest assured for a while because, according to Benson, the coating has a ten year warranty and expected to last more than 20 years.

Monolithic Domes have a roof membrane, the Airform that is inflated to give the dome its shape. Membranes are often damaged by sunlight, exposing the polyurethane foam underneath. After years of sitting in the sun, each dome needs to be recoated to maintain the structure. Severe weather, such as hail in this case, can also cause damage to the membrane.

Like any other structure, this must be maintained over the years. “This roof membrane must be maintained and coated periodically,” stated Monolithic president Michael South. “The key is to keep your dome clean, and be looking for signs of wear on the Airform.” South stated there are currently efforts to find a better coating solution, in hopes of extending the life of the membrane.

Built in 2010, the home is seven years old and the project of Kay and Ernest Mudd. The home has 4,700+ square feet over two levels with six bedrooms and five bathrooms. The dome has a diameter of 66 feet and a height of 25.5 feet. Next to the home stands Twinkie, a four-car garage named because of its similar appearance to the popular snack.
