Application

1.0 Examination:

A- Verify conditions are acceptable for application of roof restoration system.

B- Inspect built up roof to receive roof coating and make sure they are clean, sound, properly prepared and free of moisture, dirt, debris or other contaminants.

C– A comprehensive moisture survey is to be conducted to locate and identify areas of trapped moisture and saturated insulation.

D– Verify that all on-roof items, penetrations, mechanical equipment, hvac drains are in place and secure. All air conditioning and air intake vents should be suitably protected or closed.

E– Verify that areas within the vicinity of the application area as protected from overspray.

F– Verify that all roof drains, gutters, downspouts, catch basins are clean and in working order.

2.0 Preparation:

A- Cleaning: The entire built up roof surface must be clean, sound, dry and free of any contaminants that would interfere with the proper adhesion of the roof coating. This may require pressure washing, scraping, wire brushing or other means necessary while observing responsible trade practices. All loose paint and rust should be removed before applying any product.

B- Ponding Water: Contractor shall make every effort to mechanically eliminate all ponding water areas on the built up roof prior to application of any roof coating product. For roofs with minor ponding (ie. small puddles less than 1/2″ deep) that cannot be corrected, consider using our solvent system.

C- Repairs: Wet roof insulation and damaged membranes are to be removed and replaced as necessary to match existing specified material. All ponds that hold water over 1″ for more than 48 hours should be mechanically diverted.

D- Do not apply coatings until all unsatisfactory conditions have been corrected in a manner acceptable to the original built up roofing manufacturer.

3.0 Application:

A- Inspect built up roof to receive roof coating. Always perform a coating adhesion test before doing the entire job.

B- Primer: Entire built up roof shall be primed using the appropriate primer and following the application rates specified in the table below.

C- Seams: All seams, penetrations and parapet walls should be flashed using SeamStitch Polyester Roofing Fabric and PrimeLock Bonding Primer. Apply a thin coat of PrimeLockT Bonding Primer over the seam and roll out 6″ fabric over the seam and apply another coat of PrimeLockT Bonding Primer over the fabric. Encapsulate the fabric with the appropriate elastomeric coating and feathering it at least 2″ to 3″ past the edge of the fabric. Substitute PrimeLockT Bonding Primer with EnergyGuard® Butyl Rubber Coating when installing a solvent system. Read 2.02 for details.

D- Cracks/Splits: Repair all cracks and splits using the same method as seam preparation above. If cracks and splits are all over the built up roof , a full fabric system will be necessary.

E- Blisters: All blisters must be cut out and inspected for moisture content. Cut area must be thoroughly dry before applying any roof coating. Use the same repair procedure for seams.

F- Base Coat: Apply appropriate base coat using the application rates specified in the table below. Allow to dry thoroughly for 8 – 12 hours depending on humidity and temperature.

G- Top Coat: Apply appropriate top coat in a cross-hatch technique using the application rates specified in the table below. Allow to dry and cure before exposing to foot traffic.

H- Standard System: Use the Acrylic System for built up roofs with good slope and no ponding water issues. Use the Solvent System for built up roofs with minor ponding issues or when outdoor temperatures are no longer favorable for acrylic coatings.

I- Acrylic Fabric Reinforced System: SeamStitch Polyester Roofing Fabric should be installed on the entire built up roof surface. Apply a thin coat of PrimeLockT Bonding Primer on the built up roof surface, roll out 40″ SeamStitch Polyester Roofing fabric making sure there are no air pockets and the fabric lays as flat as possible. Apply another coat of PrimeLock Bonding Primer to totally saturate the fabric. Overlap edges of SeamStitch Polyester Roofing Fabric at least 4″.

J- Solvent Fabric Reinforced System: SeamStitch Polyester Roofing Fabric should be installed on the entire built up roof surface. Prime the entire roof with PrimeLockT MultiService Primer. Apply a thin coat of EnergyGuardT Butyl Rubber Coating on the roof surface, roll out 40″ SeamStitch Polyester Roofing Fabric making sure there are no air pockets and the fabric lays as flat as possible. Apply another coat of EnergyGuard Butyl Rubber Coating to totally saturate the fabric. Overlap edges of fabric at least 4″.

3.1 Application Areas

Roof Repair Coatings: All roof coatings of epdmcoatings’ can be applied for roof leaks repair and roof cracks repair. These roof coatings are applicable on metal roofs, flat roofs, concrete roofs, modified bitumen and builtup roof etc. These coatings are long lasting, cost effective and have excellent weather resistance.

RV Roof Repair Coatings: Elastomeric coatings have good performance yet very cost effective. Easiest to apply (roll-on). Quick cure. Non-flammable. EPDM comes in several standard colors including gray, …….. Liquid roof and Eternabond tape are best for RV roof leaks repair.

Pond Leaks Repair: EPDM Pond Liners requires little or no regular maintenance once installed. These pond liners give remarkable resistance to the harmful effects of ultraviolet radiation (UV), ozone and other environmental conditions. These coatings are easiest to apply, durable and cost effective.
