Stronger the Second Time Around - About Our Historic Restoration Services

About Us


The Spray-O-Bond Company was formed in 1926 by Rudolph Forrer, the grandfather of current owner Robert Forrer. During the past 84 years, 9900 jobs have been completed under the direction of Forrer family ownership including Rudy Forrer (1926-1960), Richard and Fritz Forrer (1960-1992) and Robert Forrer (1992-present). The list of historic structures that Spray-O-Bond has successfully completed is lengthy. Throughout its history, the company has remained focused on its specific discipline of exterior above grade masonry restoration. Recent projects have been focused on historic projects which require complete diagnosis and restoration of veneer systems due to the sustainability of a sound veneer structural support system. Historic fabrics of stone, brick and terra cotta comprised the majority of Spray-O-Bond’s work.

Spray-O-Bond’s staff includes Attila Barabas. Attila is General Superintendent and is a 17-year veteran of the Spray-O-Bond Company. He received masonry training in Eastern Europe and has over 37 years experience in the business.



Robert is third generation Forrer Family to run the Spray-O-Bond Company. With a background in pension fund real estate investment, he took over the day to day operations in 1992. Since then he has been very active on a national basis in the development of national standards for historic restoration of commercial, industrial and institutional landmarks. Robert was a member of Milwaukee Department of Neighborhood Services High-rise Committee which helped develop the new ordinance for façade investigation in the City of Milwaukee. He is Past President of the SEALANT, WATERPROOF AND RESTORATION INSTITUTE and currently an active member of several organizations dedicated to the preservation of historic structures.
