11 FLUID APPLIED ROOFING PART 3 EXECUTION 3.1 EXAMINATION 1. Ensure the substrate surfaces are dry, durable, free of frozen matter, loose particles, cracks, pits, projections, or foreign matter detrimental to adhesion or application of the waterproofing treatment. 2. Ensure all items that penetrate the roof surface to receive waterproofing treatments are securely installed. 3. Ensure the roof system is adequately supported and firmly fastened in place. 4. Ensure that the roofing panels have a minimum slope of 0.25 inch / foot (2.083cm/meter). 5. Ensure that the roof does not have any areas of ponding water. 6. Ensure all attached parapet/vertical walls are properly treated with the MonoSeal System. 3.2 PREPARATION 1. Remove lightning protection. 2. Protect adjacent surfaces not designated to receive waterproofing. 3. Clean and prepare surfaces to receive waterproofing treatment by removing all loose and flaking particles, grease and laitance with the use of a 3,000-psi power wash and a stiff bristle push broom. Care should be taken not to inject water into the substrate during washing. In some cases, additional drying time may be required after the cleaning process. Please consult your Agua-Seal Waterproofing Systems Technical Sales Representative for additional advice on cleaning metal roof substrates. 4. Make all necessary repairs to existing substrate. Contact Agua-Seal Waterproofing Systems Technical Sales Representative for assistance. 5. Do not apply waterproofing to surfaces unacceptable to manufacturer.

12 3.3 APPLICATION 1. Rusted areas (Field of Roof): a) Apply a 'spot' brush coating of PanelSeal Metal Primer to all areas showing signs of rusting including around seam fasteners, along the ridge vent and at metal panel edges. Allow to dry. b) Lightly moisten each fastener position along vertical and horizontal seams. Apply a 'blob' of AguaGrip Plus (fiber-bulked AguaGrip for long term waterproofing metal roof fasteners). Allow to dry. As an alternative AguaCaps may be used over fastener heads; apply a foundation coat of MonoBase, lay AguaCap into the wet MonoBase and over the fastener head. Immediately apply a saturation coat of MonoBase into and over the AguaCap. c) Consult AguaSeal s Technical Sales Representative to determine extent of PanelSeal Metal Primer coverage as necessary subject to overall condition of metal roof. Default treatment if no consultation with the Technical Sales Representative occurs; following Metal Primer spot treatment, apply a spray coating of Metal Primer to the entire field of the roof at a coverage rate of 200 ft. 2 / gal (one half gallon per square). Allow to dry. 2. Vertical Seams: In many instances, vertical seams do not need to be addressed with fabric. Consult your Technical Sales Representative for verification. a) In those instances where vertical seams do require full treatment, apply a foundation coat of MonoBase, along the length of the seam, feathering 3" either side of the mid-point of the seam. Lay 6" Agua-Seal Fabric into the wet MonoBase. Immediately apply a saturation coat of MonoBase into the fabric. 3. Horizontal Seams: apply a foundation coat of MonoBase, along the length of the seam, feathering 6" either side of the mid-point of the seam. Lay Agua-Seal Fabric into the wet MonoBase. Apply a saturation coat of MonoBase into the fabric. a) MonoBase coats direct to substrate are applied at a total rate of ft. 2 /gal ( m 2 /liter) or gallons per square, depending on the specific type of metal roof. MonoBase saturation coats over the fabric are applied at a rate of 40 sq. ft. per gallon. b) MonoBase coats should only be applied with the use of approved roof brushes. Rolling and spraying of the MonoBase coats are not permitted and will nullify the issue of an Agua-Seal Waterproofing Systems warranty.

13 4. Roof Penetrations: Apply MonoBase and a project specific size fabric up each and all penetrations through the waterproofing material a minimum of 6" (15.24cms). 5. Ridge Closures: Closures should be backed with proper backing material to the outer edge of the ridge cap. Apply a foundation coat of MonoBase, along the length of the ridge, feathering 6" either side of the mid-point of the seam. Lay 12" Agua-Seal Fabric into the wet MonoBase. Apply a saturation coat of MonoBase into the fabric. 6. Valleys: apply a foundation coat of MonoBase, 6" into the valley and feathering 6" onto the roof pan. 7. End Caps: Using Agua-Seal Waterproofing Systems approved backing materials, fill any voids in the end caps. Using MonoBase and 12" fabric seal the end cap into the adjacent pan applying the clean-cut edge of the fabric to the vertical edge of the end cap. 8. Parapet & Vertical Wall Junctions: Apply MonoBase and 12" fabric to all roof and vertical wall junctions. Apply the MonoBase treatment up and over vertical surfaces and onto the deck by a minimum of 6" inches in each direction. 9. Roof Drains: Remove drain rings and apply MonoBase and a project specific size fabric to seal the roof drains, extending into the bowl of the drain. 3.4 PROTECTION OF FINISHED WORK 1. Monitor finished system for 7 days, sweeping off birdbaths to allow for full cure. 2. Verify final film thickness as specified. If specified dry film thickness has not been achieved, application of additional coating will be required. 3. Visually inspect critical areas of the roof including roof seams and penetrations and touch up with additional MonoSeal coatings to insure complete and adequate coverage. 4. Protect completed membrane from damage by work of other trades. Schedule sequence of work so that traffic over new membrane is minimized. Institute required procedures for protection of completed membrane during installation of work from other trades throughout remainder of construction period. Do not allow traffic of any type on unprotected membrane. 5. At completion of construction activities of other trades, touch-up and restore damaged or defaced coated surfaces, if and where needed. Correct damage by cleaning, repairing, replacing, and/or recoating to make acceptable to the specifier and/or AguaSeal. Leave in an undamaged condition.
