Section 07 56 00 – Emulsion Base Acrylic Coating Roof Systems
3.11 INSTALLATION OF WALKWAYS (OPTIONAL): In high-traffic areas and around mechanical equipment, walkways should be installed to protect the coating system from damage. 3.12 FIELD QUALITY CONTROL A. Maintain Job Progress Report / Daily Log of work completed as required to assure installation is in accordance with manufacturer requirements. B. Provide on-the-job inspections, technical assistance and material application guidance as may be necessary to complete roofing material application in accordance with Tropical Roofing Products warranty requirements. 3.13 JOB COMPLETION A. Inspect completed coating system and correct all defects to meet the specification and/or warranty requirements. B. Transparent or Thin Areas: If areas appear to be undercoated, recoating may be needed to ensure final thickness to meet the Tropical Roofing Products specifications Total Dry Mils. C. Delamination: Verify that all coated areas appear to be fully adhered to the substrate. A visual inspection looking for typical signs of poor adhesion such as flaking, blistering etc. should be made. Re-priming and/or recoating will be required if such areas are apparent. D. Pin Holing: Certain job or site conditions may result in pin holing or out gassing during curing or cause pin holes in the substrate. Again, a visual inspection looking for typical signs of out gassing such as excessive pockmarks, pinholes etc. E. Delaminating: Delamination is caused when water-based coatings freeze, or solvent entrapment in solvent based coatings occurs. The coating surface may exhibit extreme wrinkles, small blisters and may have loss of adhesion. These areas will not “self-heal” and must be removed, power washed and a new coating must be applied. F. Texture Finish: Heavy patterns, blistering, “skinning,” etc. may appear in the final finish. These may be indicators that the coat is too thick, a build-up has occurred or another application problem. Check with Tropical Roofing Products Technical Representative for remedial advice. G. A Tropical Roofing Products Technical Representative will inspect the completed coating system and notify the contractor of any defects in the application. H. Restrict construction traffic and equipment movement on the completed coating system to only essential personnel. Provide appropriate protection against traffic and construction activities on completed roofs. Damage to the roof by other trades shall not be the responsibility of Tropical Roofing Products.
