GENERAL DESIGN CONSIDERATIONS HOW TO DETERMINE IF A ROOF IS A GOOD CANDIDATE FOR COATING When installed on a new roof,a roof coating should: • Be a component part of the larger warranted roofing system.This will ensure compatibility with the system and enhance overall performance of the system. • Be installed after the roof has weathered as necessary. Weathering periods may vary depending upon the type of system to which the coating will be applied. Use of a primer may also be required for certain substrates to ensure adequate adhesion. When installed on an existing roof, a roof coating should: • Be compatible with the existing roof. • Extend the remaining service life of the existing roof.Although a coating cannot add life back to a roof already beyond its service life, it can prevent a roof from aging as quickly as it would without the coating. • Only be applied to a roof that drains properly. Some coatings may be adversely affected by the presence of ponding water.Therefore, areas of the existing roof that pond water should be repaired prior to coating. • Only be applied to non-leaking roofs.While coatings may help seal some pinhole leaks not visible to the naked eye,they will not generally find and repair existing leaks. Accordingly, existing roof leaks will need to be identified and repaired prior to coating. (Allow repairs to fully dry prior to coating.) NOTE:When coating over an existing roof coating or an existing coal tar pitch roof, contact GAF Technical Services at 1-800-ROOF-411(1-800-766-3411).

If any questions arise regarding the compatibility of HydroStop® PremiumCoat® liquid-applied roofing products with an existing substrate, Installer �. shall prepare test patches to check adhesion. • Do not proceed with the installation of the HydroStop® PremiumCoat® liquid-applied roofing system until compatibility and adhesion of HydroStop® PremiumCoat® roofing system has been verified by test patches and other preparatory work has been completed and unsatisfactory conditions have been corrected. • Roof must have positive drainage.Substrate should not pond water for more than 48 hours after precipitation stops. •GAF defines "ponding" as water that does not drain or dissipate from the roof surface within 48 hours after precipitation ends. Ponding can also result from other water sources, including improperly piped air conditioning condensate and steam condensate lines. • Protect adjacent surfaces that will not be coated. • Do not apply liquid-applied roofing products to surfaces unacceptable to GAF, or under inclement environmental conditions. • Substrates must be clean, completely dry, and free of any debris before application of any liquid- applied products. • HydroStop® PremiumCoat® liquid-applied roofing products should not be used on heavy-traffic bearing substrates. If foot traffic is expected, a rooftop walkway system approved by GAF must be used. Always contact GAF's Technical Services Department (800-766-3411)for questions regarding suitable substrates, materials for test patches, or if you require additional information. PROPER PREPARATION FOR ROOF TYPES To ensure proper coating application,the existing roof membrane must be thoroughly cleaned. All dust, chalking film, bitumen exudate, greases or oils,and other loose debris should be removed prior to coating. Be careful when pressure washing to preserve the integrity of the existing roof membrane and to avoid damage to membrane seams(especially adhered seams).Allow the roof to dry completely prior to coating. Any required roof or flashing repairs should be completed and allowed to adequately cure where necessary. Refer to specific sections of this Manual for more information on roof preparation. Depending on type of existing substrate and the coating to be applied, use of a primer may be required. Surfaces which typically require primer include: metal flashings,gravel stops, and other metal edging; concrete roof decks, masonry walls and other floor surfaces,and other porous surfaces. Refer to specific sections of this Manual for detailed requirements. While rusted metal roofs can be coated, additional measures may be required. If the roof is affected by "white rust" (i.e., zinc or aluminum), it can be coated after cleaning. However, if the roof is affected by "red rust,"the rust must either be removed or treated with corrosion inhibiting primer. Additionally, all rusted fasteners should also be removed or treated with a corrosion inhibiting primer. WHAT IS BENEATH THE EXISTING ROOF SURFACE? In membrane roof systems,there is typically a layer of insulation beneath the membrane. If the roof has ever experienced leaks, it is possible that there are areas of wet insulation in the existing roofing system. All wet roof insulation must be removed and replaced prior to coating. While certain areas of wet insulation may be noticeable simply by walking on them,an infrared moisture scan is recommended to more accurately determine areas of wet insulation. Metal roofs are typically installed over a solid roof deck or over purlins and insulation. Examining the underside of the roof deck can reveal areas of wet insulation, deteriorated deck or other damage that needs to be repaired prior to coating. HydroStop®PremiumCoat®Liquid-Applied Roofing(LAR)—Version 1.2 11 MOISTURE SURVEY It is the responsibility of the roofing contractor to determine the suitability of any substrate to receive a liquid-applied coating system. Roof moisture surveys are a common tool used to assist with this determination. When the deck/substrate has more potential to "hold" water, a moisture survey may be required by GAF. aj4. . Mttip Alternately,for decks/substrates such as steel,the use of roof cuts to verify the suitability of the substrate can be effective. Where a moisture survey is performed: • GAF requires a moisture survey be conducted by the roofing contractor prior to warranty issuance for Emerald PledgeTM and Diamond PledgeTM Guaranteed Systems installed over existing roofs. • If the moisture survey shows areas of the roof that are wet, remove and replace all wet areas with new materials. Make typical repairs with original roof technology and follow the appropriate surface preparation steps. • Moisture surveys include: IR scans, nuclear scans,test/core cuts, and portable devices used to indicate moisture.

HydroStop°PremiumCoat®Liquid-Applied Roofing(LAR)—Version 1.2 24 Adhesion Testing 7 ` Adhesion testing is generally performed to verify the suitability of any substrate to receive a liquid- applied coating system. It is the responsibility of the roofing contractor to determine the suitability of has. the substrate prior to the application of a liquid-applied coating system. When adhesion tests are conducted: • Test patches shall be labeled and photographed to document adhesion results. • Installer can consult with GAF's Technical Services Department (800-766-3411)concerning all adhesion test results. GAF recommends either of the following test methods: Test Method #1: Test Patches Overview Patch testing gives information about the bond strength created between a liquid-applied product and a substrate. • Installer should prepare no fewer than three(3)test patches at Preparation different locations on the roof for all questionable roof substrates to verify adhesion of the liquid-applied coating system. • Minimum test patch size should be 1 square foot(0.09 square meter). • Allow at least seven(7)full 24 hour days of drying time after Test Method application of the test patches before checking adhesion. • Check adhesion by slicing an"X"(approx.6"[152 mm] in size) near the center of the test patch. • Using a spatula,try to remove the material at the center of the „X» acceptable Result: •Test patches that show good adhesion will release or chip away from the surface in very small pieces. Unacceptable Result: •Test patches that peel off of the surface and show the underlying substrate reflect poor adhesion. HydroStop®PremiumCoat®Liquid-Applied Roofing(LAR)—Version 1.2 25 OFFICE COPY Test Method #2: Field Peel Adhesion (Alternate to Test Patches) ASTM D903"Peel Adhesion"is found in all roof coating standards and is especially well-suited to field testing with elastomeric Overview materials.Primers and enamels may also be evaluated by a similar n F test called ASTM D3359"Tape Adhesion."It may also be important to run the test wet;this is called"wet adhesion." "x • Make a mock-up of the intended coating system on the existing r roof surface. • Duplicate any mechanical surface preparation. • Simulate cleaners and power washing. • A worn Scotch-Brite'cleaning pad makes a good power washing Preparation101 simulation. • Prime as specified. • Apply a layer of elastomeric coating to the substrate. * Installer should prepare no fewer than three(3)test patches at different locations on the roof for all questionable roof substrates to verify adhesion of the liquid-applied coating system. Test Method • Wet about 6"(152 mm)of a precut 1"(25 mm)wide by 12"(305 mm) long fabric strip with the coating. • Allow the remaining 6"(152 mm)of the fabric to be available to pull on the test sample. K `' • Apply another layer of coating to encapsulate the wetted section of fabric. .* • Allow to dry.This can be anywhere from 24 hours to 2 weeks. • In warm weather,1 day may be sufficient. • In cold weather,5 days is often required. • The standard practice is 1 week. * Soak prior to testing(best practice). • One hour is usually sufficient;use wet rag and cover with a bucket lid or plastic. • Some coatings like polyvinylidene difluoride(PVDF)or silicone may take longer. • Pre-cut 1"(25 mm)wide strips of butyl tape work faster and can be used in a post installation inspection.A"wet adhesion"version can be accomplished by soaking the roof area first as indicated above, Optional but follow with a towel dry,and then use butyl tape to run the pull test.The butyl tape can be easier to use with a gauge as it will bond to itself making a perfect loop. Quantitative Evaluation (best practice) Qualitative Evaluation * Use a force gauge such as a digital fish scale or trigger Coating tears up the substrate(cohesive pressure gauge. failure of substrate) * A loop,staple or clamp may be used to hold the fabric in Very Good:Most of the coating remains on the the gauge. substrate(cohesive failure of coating) • Pull slowly;the peak value should be above 2 pounds/ Good:Some coating remains on the substrate inch(2 PLI). (partial cohesive failure of coating) Fair:Coating pulls clean but pulls below 2 pounds/ inch(2 PLI) o Test strip comes off easily and cleanly (complete cohesive failure of coating) HydroStop®PremiumCoat®Liquid-Applied Roofing(LAR)—Version 1.2 26 A c n m n H Section 3 Quick Specs HydroStop®PremiumCoot®Liquid-Applied Roofing(LAR)—Version 1.2 27 " HydroStop® PremiumCoat® Quick Spec Directory Spec Number Substrate Specification Page# HS-1 Metal—HydroStop° PremiumCoat° 29 HS-2 Smooth&Granulated Asphaltic—HydrostopTM PremiumCoat° 30 HS-3 TPO— HydroStop° PremiumCoat° 31 HS-4 PVC—HydroStop° PremiumCoat° 32 HS-5 Hypalon°- HydroStop° PremiumCoat° 33 HS-6 EPDM—HydroStop° PremiumCoat° 34 HS-7 Structural Concrete—HydroStop° PremiumCoat° 35 HS-8 Corrugated Structural Transite Panel—HydroStop° PremiumCoat° 36 HS-9 ISO—HydroStop° PremiumCoat° 37 HS-10 Gypsum (DensDeck&SecuRock)—HydroStop° PremiumCoat° 38 HS-11 Warranty Extension/Renewal—HydroStop° PremiumCoat° 39 Quick Specs are abbreviated specifications and are not meant to replace detailed specifications.

HydroStop"'PremiumCoat®Liquid-Applied Roofing(LAR)—Version 1.2 39 CD > and C �+ v C v RI > C v m a` c 03 'R m , fa u Section 4 Care & Preventative Maintenance HydroStop®PremiumCoat®Liquid-Applied Roofing(LAR)—Version 1.2 40 OVERVIEW Due to its constant exposure to heat, cold, ultraviolet radiation, rain, snow, hail, high winds and/or am mechanical damage, a roof can be the most vulnerable component of a building's exterior. Despite .-3- P these negative effects, long-term performance can be enhanced, and major roof problems avoided, through correct design, quality materials, proper installation procedures and workmanship, and a comprehensive roof maintenance program.The cost of a comprehensive maintenance program is minimal compared to the cost of repairing and/or removing and replacing a damaged roofing system. The roofing system is a critical asset in the overall building envelope, and should be treated as such. Identifying and correcting potential problems early is paramount to ensuring that small problems do not become major issues. It is also essential in maintaining the integrity of the roof, protecting the building's contents,and avoiding interruption of the building's intended function. A thorough and consistent maintenance schedule will not only extend the life of the roofing system and lower life cycle and replacement costs, but will help protect other building components as well. UNDERSTANDING THE IMPORTANCE OF PROPER ROOF MAINTENANCE AND REPAIR Like all roofing systems, roofs that have been coated require regular maintenance and repair to enhance long-term service life.The Roof Coatings Manufacturers Association (RCMA) recommends that roofs and coatings be inspected twice each year,generally in the spring and fall, and after any major storms or high speed wind events. Additional coating should be applied as necessary to repair damage to the coating or underlying roofing substrate.Additional coating can also be applied where the existing coating has worn away. Refer to the specific sections of this Manual for more information on coating and re-coating applications. GENERAL CARE & PREVENTATIVE MAINTENANCE The following is a list of general care and maintenance recommendations that will help achieve maximum performance from the roofing system. • Provide proper drainage...to minimize standing water on the roof. Keep the roof surface clean from leaves, pine needles,twigs, paper, accumulated dirt and other debris, which tends to accumulate at and clog drains. Cut back trees or branches growing too close to the roof. Ponding of water on the surface of the roofing system will increase the probability of moisture entering the structure in the event of a puncture or other mechanical damage to the roofing membrane. • Check the building exterior...for settlement or movement. Cracks in the walls are a warning of possible cracks in the roof substrate and flashing. Ensure that overhangs,cornices,fasciae, and edging are in good condition. • Avoid damaging the roofing system by exposing it to any of the following,which could cause premature degradation of the coating or membrane: • Liquids containing petroleum products • Solvents • Grease used for lubricating rooftop units or from restaurant vents • Oils(new or old) used for air conditioning or compressor units • Kitchen waste or other animal fats • Chemicals HydroStop®PremiumCoat®Liquid-Applied Roofing(LAR)—Version 1.2 41 4"<`i • The use of catch pans (including proper drainage of these pans or other means of protection) may be used to protect the roofing membrane from exposure to grease, chemicals,and other materials that would otherwise be expelled onto the roof surface. Prolonged exposure to these materials can cause swelling and possible degradation of the roofing system if spills are not removed in a timely manner. • Check for signs of algae, mold, mildew or other plant growth on the roof, particularly in shaded areas that hold water. • Unprotected areas of the roofing system are more susceptible to damage from heavy foot traffic and additional measures must be taken to avoid damage to the system. Contact GAF at 1-800-ROOF-411 (1-800-766-3411)for recommendations where heavy foot traffic is expected. • If snow removal is necessary, use plastic shovels and be careful when working around protrusions or other areas where detail work could be damaged. Snow blowers, picks, axes and shovels with sharp edges must not be used on the roof. • Remove foreign debris, such as glass, bolts, nails, screws, metal shavings, and any other materials that may cause punctures or cuts to the liquid-applied coating or roofing system. • Limit roof access. Most roof damage is caused by individuals that are not authorized to access the roof, or by individuals that are not aware of the damage that can be caused when proper precautionary procedures are not followed. Roof access should be strictly limited to authorized personnel and outside personnel should be informed as to the precautions necessary when accessing the roof. Make a log of all visitors and maintenance personnel accessing the roof. • Make sure that maintenance personnel are warned against dropping tools and equipment on the coated roof surface in order to avoid puncturing the membrane. When servicing the rooftop HVAC units, antennas, solar panels, satellite dishes, etc., care should be taken when placing tools, metal doors, lids, pans, or sharp objects on the coating system surface. When moving roof-mounted units or equipment over coated roofs, avoid damage by placing smooth plywood over the coating membrane prior to moving any equipment. • Repair of any damage caused by misuse of the roofing system is the responsibility of the Building Owner.The Building Owner is also responsible for ensuring that any such damage is properly repaired by either the original contractor of record or another GAF-certified contractor. If timely repairs are not made to rectify mechanical damage or other misuse of the roofing system,this can result in the need for major repairs or replacement of the roof or roof coating system at the building owner's sole expense. HydroStop®PremiumCoat®Liquid-Applied Roofing(LAR)—Version 1.2 42 SEMI-ANNUAL INSPECTIONS & MAINTENANCE When conducting a semi-annual inspection,the liquid-applied roofing system or coating may be slippery when wet. Exercise caution when walking on the liquid-applied roof system or coating during or after a rain shower, or if moisture is present in the form of dew,frost or ice. Pay attention while walking on light-colored surfaces as ice or frost build-up may not be as visible as on a dark surface. Semi-Annual Inspection& Maintenance g g Consist of cleaning the membrane and then a visual examination of the roof coating system.The • inspection should include the overall coating condition as well as the integrity of flashings, vent pipes and other protrusions, skylights, drains,gutters, parapet walls and caps,adjacent walls, and mechanical equipment.Also check for evidence of any biological growth or other foreign debris. Preventative Maintenance Program Consists of regularly scheduled inspections and subsequent corrective actions, intended to maximize the life expectancy of the roofing system. It is recommended that preventative maintenance semi- annual inspections be scheduled in the spring and fall. Additional Inspections In addition to the scheduled semi-annual inspection, additional inspections should be scheduled if the roof is exposed to abusive or unusual conditions including but not limited to those listed below. Maintenance programs that include semi-annual inspections can usually be arranged through the installing contractor or another GAF-certified contractor.They can also be performed by a registered roof consultant or other qualified personnel who have been properly trained in liquid-applied roofing systems and safety.These inspections should be attended by the Building Owner and/or in-house maintenance personnel responsible for the roof.Additional roof inspections should be conducted whenever any of the following conditions occur: 1. Exposure of the roof to severe weather, such as strong winds, hail or continuous heavy rainfall. • Examine the roof for severely ponded areas, accumulated debris, and any damage to building components that may allow moisture to infiltrate the roofing membrane. The coating or liquid-applied system should also be examined in areas where severe conditions may have caused punctures,tears, abrasions or loose coating. 2. After repair or replacement of rooftop equipment, or at any other time when the roof may be exposed to activities from other trades where damage may occur. • Examine the roof for spills, debris, sharp objects, punctures, excessive wear, or other damage caused by heavy traffic or modifications to the roof. Cleaning Procedures WARNING:The liquid-applied roofing system or coating may be slippery when wet. Exercise caution when walking on the liquid-applied roof system during cleaning. 1. Remove any build-up of rocks, branches, leaves, pine needles and other foreign debris, as well as excessive dirt build-up around drains and other low areas. Use a plastic rake, medium-bristle push brush or other appropriate method for removing accumulated debris from the roof, using the least amount of pressure possible. Remove any excessive build-up or blockage from drains,gutters and downspouts. Ensure that downspouts on multi-level roofs do not dump directly onto the coated roof surface below.Trim any overhanging trees to HydroStop®PremiumCoat®Liquid-Applied Roofing(LAR)—Version 1.2 43 prevent excessive leaf and pine needle accumulation, allowing as much sunlight to the roof M; '{ as possible to help eliminate mildew and algae growth. 2. Liberally apply GAF United Cleaning Concentrate, diluted at a ratio of 1 part concentrate to 10 parts water, under low pressure to a given section of the roof at the rate of 0.4 to 0.7 gallons per 100 ft2 (1.6 to 2.9 L/m2). Allow the cleaner to sit for a minimum of 15 minutes. oar 3. Make sure that areas where algae, mold, or mildew growth has occurred are thoroughly saturated.These areas should also receive additional scrubbing with a medium to stiff bristle brush to assure the most complete removal possible. 4. Pressure rinse toward the drains using clean water and a 1,200 to 1,500 psi pressure washer. Use a fan tip on the extension wand, held no closer than 12" (305 mm)from the coated roof surface. Low areas where the dirt has accumulated may require additional agitation using a broom or cleaning pad. IMPORTANT: Roof wash-off catchment systems should be in place when required. Be sure to follow state and local requirements for roof-wash off catchments during the cleaning process. HydroStop®PremiumCoat®Liquid-Applied Roofing(LAR)—Version 1.2 44 INSPECTION CHECKLIST Pre-Inspection 1. Prior to the actual roof inspection,a detailed roof plan should be prepared, on which any „ , �,` defects and notes can be recorded. "N` 2. Prior to going onto the roof itself, inspect the underside of the deck (if accessible), as well as the outside of the building. Note any signs of excessive moisture or deterioration.These observations can give clues to not only problems with the roof, but also other conditions affecting the performance of the building envelope. GAF Inspection Checklist Area of Concern Treatment ✓ Roof Membrane&Flashings • Ensure that the overall roof coating membrane is sound and free of mechanical damage,splits,crazing,and cracking.In areas prone to standing water,inspect the coating surface for signs of blisters, delamination,or degradation caused by biological growth. Roof Drains&Scuppers • Ensure that roof drains and scuppers are clear and free of all debris to allow for proper drainage.Check drain covers to verify that they are tight and properly fastened.Ensure that the coating around drains and scuppers is sound and free of blisters,tears,and delaminations. Parapet Walls&Caps • Inspect interface between roof deck and parapet walls to ensure that there are no splits or tears,and that the coating membrane is fully- adhered and sound.Examine parapet walls and caps to ensure that there are no cracks or breaks in the substrate or membrane that will allow moisture to enter beneath the coating system. Protrusions • Inspect the reinforced coating around all protrusions,such as vent pipes, for any signs of splits,tears or delaminations around the base.Ensure that vent pipes have the proper caps installed.Inspect coating to ensure that it is still self-flashing and secure around the top of all protrusions. Roof Mounted Equipment •All rooftop equipment should be inspected to ensure that it is well- secured to the base risers,and that the coating and reinforcement around the base is sound and free of blisters,tears and delaminations. Skylights •Check the reinforcement around all skylights to ensure that it is sound and free of blisters,tears and delaminations. Other Details •Check the bricks and mortar on chimneys,as well as caulking or joints in metal flashings such as copings,counter-flashings,rooftop units,curbs, caps,expansion joints,etc.Repair or replace caulking as necessary. Moisture Analysis(optional) • If damage has caused concern with moisture penetration into the roof substrate,a non-destructive moisture detection survey can be conducted to provide an accurate analysis.Two common methods are nuclear metering and infrared thermography.A moisture meter probe can also be inserted through the coating;however,this is a destructive method and will require the damage be repaired. Minor Repairs •Areas found to need minor repairs(e.g.,small punctures and tears)during the inspection may be repaired with Roof Mate Butter Grade.More extensive repairs may be treated with Roof Mate Butter Grade product with fabric.For project-specific recommendations,please contact GAF's Technical Services. HydroStop®PremiumCoat®Liquid-Applied Roofing(LAR)—Version 1.2 45 ROOF SPECIFIC LEAK INVESTIGATION s ° On metal decks, it is important to identify the direction of the deck flutes and deck slope. Moisture I.E may infiltrate through the roofing system, migrate in the lower flutes of the deck, and leak inside the building in low areas. On concrete decks or on projects where the existing roofing material is left in place, leaks may result irg from moisture entrapment in the original installation. On poorly insulated roofing assemblies, leaks may occur as the result of condensation. It is therefore important to determine the leak location and frequency. Sources of air leakage should be sealed if possible. 1. Begin leak investigations by conducting a thorough visual inspection of the general location on the roof where leaks have been detected inside the building. 2. Inspect detail areas such as drains,vents, scuppers, HVAC and other roof-mounted equipment, parapets, ponded water areas,etc. If the roof is dry at the time of investigation, areas where water ponds can be identified by evidence of accumulated residue on roof membrane. 3. Examine lower areas of the roof for moisture beneath the roof coating system (soft insulation can be detected when walking over the roof). 4. Check areas around mechanical rooftop equipment, drains, skylights, roof hatches, expansion joints, pipes,vents, etc.to identify cuts or punctures in the coating membrane. 5. Examine the condition of metal flashings(i.e., edging, coping, expansion joint covers, parapet caps, etc.)for cracks and improperly sealed joints. 6. When a visible source of the leak has not been identified,wet the system at the anticipated leak area with water and examine the interior area for leaks. 7. Often, an inspection of the underside of the deck will reveal signs of water leakage and/or air infiltration. EMERGENCY REPAIRS GAF must be notified of any leaks within 30 days of discovery of a leak or GAF will have no responsibility for making repairs or replacing that portion of the products that leak as a result of a manufacturing defect. The Building Owner may make temporary repairs to minimize damage to the building or its contents in an emergency. Only qualified workers should perform temporary repairs. These repairs will not result in cancellation of the applicable guarantee or warranty as long as they are reasonable and customary and do not result in permanent damage to the GAF roofing materials. When weather conditions permit, permanent repairs should be completed by a GAF-certified contractor at GAF's direction if it is a covered leak or at the building owner's direction for non-covered leaks. Repairs should not be made with asphalt-based products unless a wet patch type product is needed for emergency purposes. If wet patch products are used they must be completely removed at the time permanent repairs are made. HydroStop®PremiumCoat®Liquid-Applied Roofing(LAR)—Version 1.2 46 Temporary Dry Surface Emergency Repairs • Clean the coating surface around the damaged area using GAF United Cleaning Concentrate. • Rinse the area with clean water and allow it to dry. • Apply HydroStop® PremiumCoat® Butter Grade Flashing and embed with fabric as needed to provide additional strength. Contact GAF Technical Services before any other product is used ;'= to confirm its suitability. x_ Specific Repairs to Liquid-Applied Roofing Systems over Spray Polyurethane Foam (SPF) Insulation • Minor breaks in the coating or mechanical damage to sprayed polyurethane foam (SPF) may be repaired with approved urethane caulk and then top-coated with HydroStop® PremiumCoat® Butter Grade Flashing with or without fabric.The damaged foam must be completely cut away prior to repairing. If the repaired area is larger than 2" (51 mm) in diameter,consult GAF Technical Services for proper repair procedures. Note: If silicone is used for repair,the area must be filled with Unisil with Unisil Fibers. • Large blisters that are not leaking but have broken open should be removed and repaired. If the blister has not broken open, GAF recommends leaving it in place. Specific Repairs to Liquid-Applied Roofing Systems Not Over Spray Polyurethane Foam (SPF) Insulation • Repair minor mechanical damage to the liquid-applied coating membrane with HydroStop® PremiumCoat® Butter Grade Flashing and/or approved urethane caulk, and then top-coated with an approved GAF product.The damaged membrane must be completely cut away prior to repairing. If the repaired area is larger than 2" (51 mm) in diameter,consult GAF Technical Services for proper repair procedures. • If the liquid-applied roofing system incorporates reinforcement fabric,then the repair should use HydroStop® PremiumCoat® Butter Grade Flashing with or without fabric. ROOF ALTERATIONS General GAF must be notified of any planned roof alterations prior to such alterations being made. Coverage under the guarantee or warranty may be jeopardized if: • GAF is not notified of alterations. • The original contractor of record (or another GAF-certified contractor) does not do the required work. • Non-GAF products are used.
