SURFACE PREPARATION |
| On existing built-up roofs, loose gravel and dirt are removed by power brooming and vacuuming. If necessary, blisters and saturated areas are removed. Sandblasting and/or priming are applied to metal surfaces as required. Most roofing surfaces are also primed prior to foaming. |
|
FOAM APPLICATION |
| Polyurethane foam is applied with a two component proportioning machine. This provides mixing of the components on the spray gun. The foam is applied as a liquid and rises in a matter of seconds. Within minutes, the surface is firm enough to be walked upon. The roof is sprayed to design thickness. Flashings, penetrations and parapet walls are sprayed to form one monolithic surface. Depressions due to roof sagging can be built up by spraying to facilitate proper drainage. |
|
INDUSTRIAL COATING |
| After curing of the foam surface, an industrial elastomeric coating is applied. This weather resistant coating is normally applied in two or more coats for uniform coverage. These coatings are designed to withstand water, ultraviolet radiation and normal wear for many years of service. The use of a white coating further reduces heat load and thermal stress in the structure. |
