When properly applied, coatings can provide significant advantages to a roof system. Coatings have been documented to expand the service life of existing roofs, improve a building’s energy efficiency, resist degradation from chemicals and ultraviolet radiation and eliminate the formation of small cracks associated with these degenerative conditions. Improper coating application leads to premature coating failures, which could lead to the demise of the roof system.
The spray equipment used can be any type that is capable of spraying the coating in an even application. In roof coating applications, airless sprayers are used most often. The viscosity of the coating material, the internal diameter size of the hose and the length of the hose are important determining factors for the proper selection of the spray equipment. For guidance with the spray equipment selection process, consult the material manufacturer for the type of sprayer that provides the best performance with their materials.
