Contractor shall perform rehabilitation of existing coated SPF Roofing System using good roofing practice, some areas may require removal of the coating and/or the insulation; other areas shall require surface preparation and recoating with silicone coatings and granules. Areas shall be as described by the specifier and/or the contractor. Areas that are determined to have ponding water shall be addressed as follows. Scarify the top layer of coating and foam down to an acceptable substrate. Apply a thin layer of BASF SKY TITE 1800 primer over the scarified substrate and let it dry.

After the first layer foam has cured additional layers of SPF can be applied in order to insure positive slope.
