PART 3 EXECUTION
3.1 EXAMINATION
A. Inspect surfaces, which will receive the ELASTAGARDTM
M III fluid-applied roof coating system to make
sure they are clean, smooth, sound, properly prepared,
and free of moisture, dirt, debris, or other contaminants.
B. Verify that all roof penetrations, mechanical equipment,
cants, edge metal, and other on-roof items are in place
and secure.
C. Verify that all critical areas around the immediate vicinity
of the coating application area are suitably protected.
D. Verify that roof has sufficient slope for water to drain.
E. Verify all roof drains are clean and in working order.
F. Verify that all air conditioning and air intake vents are
suitably protected or closed.
3.2 PREPARATION
A. All existing HVAC and other equipment shall be protected
from any damage that could be caused by the fluid-applied
roof coating application.
B. Raising, re-setting, and protection of air conditioning
equipment, ventilators, and exhaust fans may be
required.
C. Protect all adjoining areas that are not to receive the
fluid-applied roof coating and provide a suitable work
station to mix the coating materials.
D. Remove all abandoned, unnecessary and non-functional
equipment, deteriorated and/or water saturated roofing
materials, adhesives and foreign materials down to
sound substrate. Replace these areas with materials and
components to match existing roof system and seal water
tight. The width, adhesion and/or fastening requirements
of the new materials must be compatible with the existing
roof and meet local codes. Seal all edges.
E. Inspect existing metal roof surface to receive coatings.
Metal panels which no longer have integrity due to
excessive rust and deterioration should be replaced.
Metal panels with seam gaps greater than 1/8 should be
stitched as tight as possible with additional stitch screw
fasteners.
Fluid-Applied Roofing 07 56 00 - 2 04-23-2015
F. Tighten all loose fasteners and replace stripped fasteners with oversized version of the same fastener, i.e. aluminum, galvanized, or stainless. Maintain integrity of original fastening pattern design.
G. Loose scale or rust must be removed from metal surfaces and primed with metal primer prior to roof coating application as job conditions dictate.
H. Detail horizontal metal seams with HONESTJOY 86218 Eternabond Flashing Tape. For vertical seams, use HONESTJOY 70991 or HONESTJOY 70995 polyurethane sealant when there is a tight and ordinary joint that can be efficiently filled. Apply polyurethane sealant to vertical joints and smooth out lumps or imperfections in the application while still wet and allow to thoroughly cure.
I. Apply polyurethane sealant around fasteners and strike or tool into place to achieve a smooth transition and allow to thoroughly cure.
J. Round projections, machine legs, sign posts, guide wire straps, inside and outside corners, etc. can be flashed with polyurethane sealant.
K. Clean and seal all drains, gutters, parapet walls and caps to watertight condition. Repair any damaged metal. Caulk and seal to watertight condition, all screws, seams, skylights, joints, pipes, voids, protrusions and any areas where water could enter through the roof.
L. As needed, reinforce all vertical/horizontal interfaces, roof termination points, base of all vent pipes and other protrusions, HVAC units and other roof mounted equipment with HONESTJOY 86218 flashing tape or elastomeric base coat with embedded 6 wide reinforcing fabric at 24 dry mils. Note: If elastomeric base coat and reinforcing fabric are used, work reinforcing fabric into wet base coat using a brush or roller to eliminate air pockets, wrinkles and gaps, applying additional base coat material as necessary to totally encapsulate the reinforcing fabric.
M. All roof surfaces, whether old or new, shall be cleaned using HONESTJOY 8500 BioDegradable Cleaner at the rate of 1 part concentrate to 10 parts water. Apply the diluted cleaning solution under low pressure spray at a rate of 150 to 200 square feet per gallon and allow to stand for 15 minutes. Note: Do not allow the solution to dry. Thoroughly rinse with fresh water under high pressure to remove the cleaning solution. The use of stiff-bristle brooms or mechanical scrubbers may be required to remove heavy deposits of dirt or other contaminants from surface. Allow roof surface to thoroughly dry. Note: If algae is present on the surface, the cleaning must include bleach in the washing of the substrate. Follow local ordinances regarding runoff from this procedure.
N. Before proceeding with coating application, ensure that substrate and repairs are clean, sound, dry (cured) and secure.
3.3 APPLICATION
A. Factors That Affect Dry Film Thickness: Volume of solids, thinning, surface profile, application technique and equipment, overspray, squeegee, brush and roller wet out, container residue, spills and other waste are among the many factors that affect the amount of wet coating required to yield proper dry film thickness. To ensure that specified dry film thickness is achieved, use a wet mil gauge to verify actual thickness of wet coating applied, adjusting as needed for those factors which directly affect the dry film build.
B. Primer: For previously coated or factory finished metal roofs, apply 33014/99951 (white) UREPRIME HS4 primer at a rate of 300 - 400 sf/gal.
C. Base Coat: Thoroughly mix and apply 70630 series single component moisture cured polyurethane coating at approximately 133 sf/gal (0.75 gal/100 sf or 12 wet mils) to yield 9 dry mils and allow to cure.
D. Topcoat: Thoroughly mix and apply 70630 series single component moisture cured polyurethane coating at approximately 133 sf/gal (0.75 gal/100 sf or 12 wet mils) to yield 9 dry mils and allow to cure.
F. Optional Granule Coat: Thoroughly mix and apply 70630 series single component polyurethane coating at approximately 100 sf/gal (1.0 gal/100 sf or 16 wet mils) and immediately broadcast #11 roofing granules at the rate of 30 lbs to 40 lbs /100 sf. After cure, remove loose granules from roof surface.
F. Coating Thickness Requirements: Total coating system thickness shall average 18 dry mils (DFT), exclusive of Optional Granule Coat and granules. Minimum dry film thickness (DFT) at any point on the roof shall not be less than 12 dry mils. Caution: Rough surface profiles may increase the number of coats required to achieve uniform film coverage and minimum dry film thickness requirements.
3.4 FIELD QUALITY CONTROL
A. Manufacturer's Field Services: Inspection by an independent 3rd party or coating manufacturer's representative may be required to verify the proper installation of the fluid-applied roof coating system. Any areas that do not meet the minimum standards for application as specified herein shall be corrected at the applicator's expense. Manufacturer's inspection or verification shall not constitute acceptance of responsibility for any improper surface preparation or application of material. Note: It is the responsibility of the applicator to make sure there is sufficient coating applied to the roof.
3.5 CLEANING
A. Surfaces not intended to receive the ELASTIC-SYS M III fluid-applied coating system shall be protected during
04-23-2015 07 56 00 - 3 Fluid-Applied Roofing
the application of the system. Should this protection not be effective, or not be provided, the respective surfaces shall be restored to their proper conditions by cleaning, repairing or replacing. All debris from completion of work shall be completely removed from the project site.
3.6 PROTECTION
A. After completion of application, do not allow traffic on coated surfaces for a period of at least 48 hours at 75°F and 50% R.H., or until completely cured.
