5 F. Source Limitations: Components listed shall be provided by a single manufacturer or approved by the primary roofing manufacturer. 1.9 PRE-INSTALLATION CONFERENCE A. Prior to scheduled commencement of the roofing restoration and/or coating, a meeting must be conducted at the project site with the contractor, architect, owner, Tropical Roofing Products representative and any other persons directly involved with the performance of the work. The contractor shall record conference minutes to include decisions, agreements, and open issues and offer copies of recorded discussions to all attending members. The main purpose of the meeting is to review proposed methods and procedures related to roofing work. 1. Observe and inspect all roofing substrates and discuss conditions of substrate, flashings, penetrations and other preparatory work to be performed. 2. Review Tropical Roofing Products Eternalastic Restoration/Coating system requirements (TRP specifications, contractor detail drawings and the Contract Documents). 3. Review required submittals, both completed and in progress. 4. Review and finalize the restoration/coating schedule, and verify availability of materials, contractor s personnel, equipment and facilities needed to consistently maintain progress and avoid unnecessary delays. 5. Review required inspection(s), testing, certifying, and material usage accounting procedures. Review forecasted weather conditions REGULATORY REQUIREMENTS Work shall be performed in a safe manner, conforming to federal, state and local codes DELIVERY, STORAGE, AND HANDLING A. Store and handle Tropical Roofing Products materials in a manner that will ensure there is no possibility of contamination. B. Store materials in a dry, well ventilated, weather tight location at temperatures between 50 degrees F (10 degrees C) and 80 degrees F (27 degrees C) until the products are ready to be applied. C. Do not stack material pallets more than two (2) high. D. Do not subject existing roof to unnecessary loading of stockpiled materials. E. All packages must be labeled and clearly visible F. Polyester Fabrics must be stored in a dry, and protected environment G. Polyester Fabrics should be handled in a manner to prevent damage to edges and ends. H. Coatings, Emulsion and Mastics must be stored at the recommended temperatures protected from inclement weather conditions. 01/22/ Tropical Roofing Products. All rights reserved. Page 5

6 I. Do not allow products to freeze. J. Keep product lids tightly closed on all containers when not in use. K. Locate materials temporarily stored on the roof in approved areas and distribute the load to stay within the live load limits of the roof construction. L. Select and operate materials handling equipment in a manner not to damage existing substrate and applied roofing. M. Installer shall take all necessary precautions measure to ensure that damage and overspray will not occur. Tropical Roofing Products is not responsible for damages caused by the overspray of its products PROJECT CONDITIONS A. Do not begin work if temperatures are expected to fall below 50ºF during the duration of the job (Temperature must be 50 F and rising). B. Roof surface must be dry with no precipitation in the forecast for the next 48 hours. C. Do not begin work if rain or heavy dew is expected within twenty four to forty eight hours (24-48) of application. D. This Restoration/Coating System is water based and should be applied when weather conditions permit proper application and drying. E. Applicator must allow for sufficient cure time for each product, because curing time for all products is critical. F. Other environmental conditions such as humidity, mist, dew, extreme temperatures, and condensation can affect cure time of products in an adverse way. G. The system should not be applied if there is ice or frost on the roof surface/deck. H. Upper temperature restriction (both air and substrate) for application of Tropical Roofing Products is 120 degrees F. If substrate temperatures exceed 120 degrees F, TRP products shall be applied during cooler periods of the day. If this is not practical, the substrate shall be cooled with water, and then TRP products applied just after the water has flashed-off. I. No moisture may be present when applying TRP products. Taking into consideration the UV curing properties of TRP Roofing Membrane and Flashing Grade, allow for sufficient daylight hours necessary for curing of materials. J. If ponding water is present in any area for more than 48 hours, this system is not recommended. 01/22/ Tropical Roofing Products. All rights reserved. Page 6

Penetrations: #950 Eternamastic along with #930 Polyester Fabrics shall be applied around the base of the penetration, extending at least 4 inches onto the vertical and 4 inches onto the base. Embed a 6 inch width of #930 Polyester Fabrics using additional #950 Eternamastic, as necessary to accommodate the shape of the penetration. Both the top and bottom of pipe shall be flashed using #950 Eternamastic along with #930 Polyester Fabrics as described above. G. Skylights: Curb skylights shall be treated in the same fashion as curb flashings. The entire perimeter shall be flashed with a minimum 6 X1/16 inches of #950 Eternamastic along with #930 Polyester Fabric. All exposed skylight fasteners shall be encapsulated with #950 or #951 flashing mastics. Do not bridge fasteners. #930 Polyester Fabric shall be cut around all fasteners so the fabric lies flat. H. Inspect Preliminary Work / Flashing Details for problem areas (e.g., gaps, cracks, fish mouths, air pockets, etc.) to ensure that work is complete and satisfactory. 01/22/ Tropical Roofing Products.

13 3.5 RESURFACING EPDM A. Moisture Scan: A moisture scan shall be performed on the roof system to determine the suitability of the existing roof for application of a Tropical roofing system. Any wet or deteriorated areas shall be removed and replaced. B. If the EPDM roof is newly installed, do not coat with the #911 Eternalastic Coating System for a minimum of 30 days to allow for full cure of the EPDM system. C. Preparation: Preparation of the roof substrate is the responsibility of the installer, who shall address and correct all of the conditions listed in this section. Examine substrates to receive new roofing. Do not proceed with the installation of the Tropical roofing system until unsatisfactory conditions have been corrected in a manner acceptable to the Tropical Roofing Products. D. Treatment of Ponding Water Areas: Installer shall make every effort to mechanically eliminate all ponding water areas on the roof prior to application of TRP products. Ponding water is defined as water that does not properly drain and remains on the roof for more than 48 hours after precipitation stops. E. Membrane Holes: Repair: Thoroughly inspect the EPDM membrane for defects (holes and other openings). If the defects are larger than 1/8, repair before coating application using either #950 Eternamastic with #930 Poly or #951 in a three course fashion (refer to flashing section for details). F. Deteriorated Seams: Repair all delaminated or open seams using either #950 Eternamastic with #930 Poly or #951 in a three course fashion (refer to flashing section for details). G. Pitch Pans: Pitch pans shall be capped with sheet metal so they may be sealed using either #950 Eternamastic with #930 Poly or #951 in a three course fashion (refer to flashing section for details). H. Condensation Lines: Condensation lines shall be installed from HVAC units to gutters as part of the overall drainage system. The type of piping used for condensation lines may vary depending on local building codes. I. Membrane Cleaning: If grease, oils or heavy contaminants are present on the roof surface, remove them with a mild detergent prior to final cleaning. Bleach may be used to remove any algae, fungus or vegetation present. J. Apply #990 Eternalastic Rinseable Primer at a rate of 1 gallon per 500 sq. ft. #990 Eternalastic. (#990 Eternalastic EPDM Primer significantly improves the adhesion of #911 Eternalastic to a EPDM rubber surface). K. #990 Eternalastic Rinseable Primer should be applied with a conventional compressive air sprayer/hudson sprayer. L. The EPDM surface must next be pressure washed with water (Two times) at a rate of max 2500 psi to remove remaining dust and dirt. M. #990 Eternalastic Rinseable Primer is mandatory for maximum adhesion. Any residue of the #990 Eternalastic Rinseable Primer left on the EPDM will also have disastrous adhesion results. Therefore, a complete second rinse with water is essential. N. If asphalt is present on the EPDM membrane, the asphalt must be treated with #980 Eternalastic at a rate of 1 gallon per 100 sq. ft. Application can be by brush, 01/22/ Tropical Roofing Products. All rights reserved. Page 13
