EpoxyFlex Roof Coating System Over Smooth Surfaces EPDM, PVC, RUBBERS, HYPOLON PREPARATION 1. Make all necessary repairs as described in the Repair Section of this manual. 2. Seal around all protrusions, such as details, air-conditioners, pipes, stands, etc. with an appropriate product (cutback, modified emulsion, plastic roof cement, urethane calk, etc.). 3. Tighten and secure all fastening devices ( nails, screws, weldable seams, etc.) to prohibit the device from backing out. Secure all fastening devices against moisture penetration. Do not rely on the EpoxyFlex Roof Coating System or the EpoxyFlex Repair System to secure in any way fastening, sealing, or other such devices. 4. Prepare surface appropriately for coating. Preparation may require sweeping, brooming, and/or power washing, scraping, vacuuming, etc. Surface preparation shall always be in accordance with the highest standards of trade practices. A. The coating surface shall be completely dry, clean (clear of dirt, oxidization, oils, rock, soap, or any substance or circumstance that may impede adhesion), structurally sound and water tight. B. On aged membrane surfaces, it is highly recommended that the entire surface be cleaned with a mild liquid cleaning solution, working it into the surface with a stiff bristled broom to remove residue buildup. Immediately rinse worked area with clean water and allow to dry thoroughly. Any areas of non-removable substances must be capped before application of roof coating. 5. Immediately prior to coating application, remove all caps from parapet walls. Detach exposed objects, flashing, and other obstructions to a contiguous monolithic coating flow that are removable without disturbing structural integrity. DO NOT REMOVE anything that threatens a seal, integrates water penetration or deteriorates decking integrity.
