mechanical adhesion.
2. Patch holes and cracks before installation.
F. Repair voids and delaminated areas with cementitious and epoxy patching
materials.
3.2 MIXING
A. Mix materials in accordance with manufacturer’s instructions.
3.3 APPLICATION – GENERAL
A. Apply materials in accordance with manufacturer’s instructions.
B. Do not apply materials to damp, wet, or contaminated substrates.
C. Surface Prestriping and Detailing:
1. Prestripe with primer 1 inch (25 mm) beyond surfaces that require detail
work.
2. For nonmoving joints and cracks less than 1/16 inch (1.6 mm) wide, apply 25
wet mils (0.6 mm) prestriping of base coat over cured primer. Apply base
coat to fill and overlap joint or crack 3 inches (76 mm) on each side.
Feather the edges.
3. Dynamic cracks and joints over 1/16 inch (1.6 mm) wide shall be routed to a
minimum of 1/4 inch by 1/4 inch (6 mm by 6 mm) and cleaned. Install bond
breaker tape to prevent adhesion to bottom of joint. Prime joint faces
only with sealant primer and fill with sealant. Fill joints deeper than 1/4 inch
(6 mm) with backer rod and deep joint sealant. For cracks, sealant shall be
flush with adjacent surface. For expansion joints, sealant shall be slightly
concave.
4. Sealed joints 1 inch (25 mm) or less shall be coated over with deck coating
system.
5. Expansion joints exceeding 1 inch (25 mm) wide, including primary wide
expansion-joint system, shall not be coated.
6. Where coating system will be terminated and no wall, joint, or other break
exists, cut 1/4 inch by 1/4 inch (6 mm by 6 mm) keyway into concrete. Fill
and coat keyway as application of base coat progresses.
D. Metal Surfaces:
1. Remove dust, debris, and other contaminants from vent, drain pipe, and
post penetrations; reglets; and other metal surfaces. Clean surfaces to

bright metal and prime with sealant primer. Provide cant with deep joint
sealant to eliminate 90-degree angles.
2. Detail cant with primer and base coat in accordance with manufacturer’s
instructions before application of deck coating system.
E. Plywood Surfaces:
1. Plywood shall be smooth faced, APA stamped, and exterior grade.
Construction shall conform to code, with plywood not less than 15/32 inch
(12 mm) thick. Plywood spacing and deck construction shall be in
accordance with APA guidelines.
2. Priming is not required if plywood is clean and dry.
3. Caulk seams with plywood joint sealants. Prestripe 4 to 6 inches (102 to
152 mm) wide with 25 wet mils (0.6 mm) of base coat. Reinforce seams
between plywood sheets and between flashing and plywood deck by
embedding reinforcing fabric into prestriping.
F. Priming:
1. After thoroughly vacuuming surface, apply primer to properly prepared
deck surfaces at rate of 200 to 250 square feet per gallon (4.9 to 6.1
m2/L). Force primer into pores and voids to eliminate pinholes. Do not
apply over prestriping.

encapsulate.
3.6 EXTRA-HEAVY-DUTY TRAFFIC SYSTEM
