- Applications
Surfaces must be dry, free of dirt, loose debris, oils, grease or any substance that could interfere with adhesion. Refer to the POLAPRIME Data Sheet for information regarding selection of appropriate primer, if necessary. Reinforcing over seams on metal roofs is achieved by embedding ROOFAB into a fresh coat of POLAROOF RAC applied at 15 to 25 mils wet thickness. The fabric is then brushed thoroughly to squeeze the POLAROOF RAC upwards to remove all voids, fishmouths and dry spots. A second coat is then applied to seal the surface of the fabric. Bolt‐heads on metal roofs should be daubed with sufficient POLAROOF RAC that they are encapsulated to the point of rundown. As soon as the POLAROOF RAC has dried, it may be coated with POLAROOF RAC or other compatible topcoat.
Application over E.P.D.M., modified and other rubber roofs requires the preparation detailed above, including reinforcement of seams. Some types of rubbers will swell slightly immediately upon application. This is normal, the adhesion process is complete when the original dimensions have returned. New urethane foam should receive 2 coats of POLAROOF RAC at 15 mils wet thickness per coat. Sudden precipitation will not wash POLAROOF RAC off when wet or newly applied, but will produce a mottled, dull appearance that is not detrimental to overall appearance. POLAROOF RAC should never be applied to a wet or damp surface, or pinholes may result.- Maintenance
Damaged areas may be repaired by cleaning surface and application of POLAROOF RAC as described in application section.
