thoroughly rinsing to remove all traces of the solution.
Power washing of metal roof surfaces to remove all loose rust or scale is mandatory before
application. Use a high volume air broom or compressed air to remove residual dust rust
perforations, etc. Deteriorated metal roof decks must be repaired or replaced prior to the
application of the coating system.
3.3 INSTALLATION
A. General Installation Requirements:
1. Install in accordance with manufacturer's instructions.Apply to minimum coating
thickness required by the manufacturer.
2. Cooperate with manufacturer, inspection and test agencies engaged or required to
perform services in connection with installing the roof system.
3. Insurance/Code Compliance:Where required by code, install and test the roofing
system to comply with governing regulation and specified insurance requirements.
4. Protect work from spillage of roofing materials and prevent materials from entering or
clogging drains and conductors. Replace or restore work damaged by installation of
the roofing system.
5. All primers must be top coated within 24 hours of application. Re-prime If more time
passes after priming.
6. Keep roofing materials dry during application. Phased construction can be allowed as
long as no, more than 7 days pass between coats excluding primers.
7. Coordinate counter flashing, cap flashings, expansion joints and similar work with
work specified in other Sections under Related Work.
8. Coordinate roof accessories and miscellaneous sheet metal accessory items,
including piping vents and other devices with work specified in other Sections under
Related Work.
B. Metal Surface Roof Restoration: Renovation work includes:
1. Surface Preparation: Remove loose flaking rust, dust, dirt, debris, secure all gaped
panels and replace all loose fasteners with next size larger.
a. Remove rust by the most rigorous method suitable for the particular project and
as approved by Garland.
b. Tighten all fasteners and verify that neoprene washers are in place.
c. Replace missing fasteners using oversize fasteners as necessary.
d. Seal all fastener heads by applying a heavy dab of compatible sealant to the
tops and around of all fastener heads.
1) White-Knight Plus/Stallion Plus
2. Flashings: Repair/Replace metal flashings, pitch pockets, etc.
3. Primer:
a. Immediately after rust has been removed, prime surfaces with White-Knight
Metal Primer/Stallion Metal Primer at 1/4 gallon per 100 SF to prevent rust
from reoccurring.
4. Reinforcement: Base coat and treatment of field seams and around penetrations:
a. Application of White-Knight Plus Base Coat/White-Stallion Plus Base Coat or
Renton Municipal Airport NW Seaplane Hangar Roof Restoration
White-Knight Plus Base Coat WC on field seams,flashings and around
penetrations
1) Verify that the surface to be coated is properly prepared.
2) Restore the surface to a suitable condition if roof surface becomes
contaminated with dirt, dust or other materials that will interfere with
adhesion of the coatings.
3) Apply materials at specified dry film thickness.
4) Apply White-Knight Plus Base Coat/White-Stallion Plus Base Coat or
White-Knight Plus WC Base Coat at minimum 6 inch wide stripes over all
seams,flashings and around penetrations at 2.0 gallons per 100 SF.
5) Use fabric reinforcement when panels are gapped and cannot be be
cured tightly together.
6) Allow to dry for a minimum of 24 hours before applying finish coats.
7) On vertical surfaces to achieve proper application rate cut your
application into two coats to avoid sagging and runs of coating.
5. Coating:
a. Material:Apply in a uniform manner at 2.0 gallons per 100 SF over the entire
roof surface.
1) White-Knight Plus/Stallion Plus
b. Use special attention to coating flashings and other critical areas to build
adequate membrane thickness.
c. Use multiple coats on verticals to prevent sagging.
d. Apply to Garland's minimum membrane thickness over the entire roof surface.
6. The Final White Knight Plus system is to receive 2Gal per 100 sq/ft of base coat and
2Gal per 100 sq/ft of top coat.
