A one coat application of Liquid Rubber 9981 will produce a 20 mil(.5mm) dry film. No primer is need even if metal has tightly adhering corrosion. Rubber & Thermoplastic membranes Repair delaminated seams; resurface deteriorated flashing in place; stops embrittlement of Hypolon and PVC; recoat single ply EPDM.
One coat will protect foam against UV degradation.
Asphalt based coating
Liquid Roof coatings/Liquid Rubber coatings should not be applied directly over an asphalt based coating. Water based acrylic elastomeric coatings may be used as intermediate coats before applying Liquid Roof/Liquid Rubber. Asphalt's based applications should be considered as being unstable materials and are excluded from warranty coverage. Caution-Latex house paints can not be substituted in place of the acrylic elastomeric coatings.

Commercial implementation to Plywood
Can be applied direct to plywood and lumber; however, we suggest a non oil-based primer.
EPDM Rubber will penetrate into fissures at joints between old and new concrete. Product will also penetrate into surface pores unless concrete is trowel finished or pores are first sealed with a primer. Rubber will effectively waterproof tiles and rain gutters made of concrete or adobe type materials that provide a long lasting Repair.
Flashing and Repair
Roof to wall flashing can be formed in place by reinforcing the EPDM rubber with polyester fabric. No mechanical fasteners are needed. Quick repair to reinforce weak areas or bridge cracks repair can also be made in similar fashion.
