PART THREE: EXECUTION
3.1
EXAMINATION
A. Examine substrate to receive
static control coating system. Notify Architect if substrate is
unacceptable. Do not begin preparation or application until
conditions are acceptable.
B. Pre-application
Product Testing: Pre-test material bond strength to substrate
per ElectraSeal product instructions.
C. Test vapor emission of
concrete slab (if applicable) per calcium chloride test method
ASTM F-1869. Should concrete vapor emissions results exceed 8
lbs per 1,000 SF/24 hour period contact United SCP prior to
proceeding with installation.
D. Ensure new
concrete has the following properties:
1) Maximum water/cement ratio of 0.45
2) Cured 60 days at a minimum of 70 degrees F.
3) Minimum compressive strength of 3,500 PSI.
4) Minimum tensile strength of 200 PSI.
3.2 SURFACE PREPARATION
| Specifier Notes: A
properly prepared substrate is essential for successful
application. Contaminants, dust and sealers of an
unknown origin may inhibit bonding of coating to
substrate. |
A. Prepare substrates in accordance with
manufacturer's instructions.
B. Ensure substrate is clean, free of dirt, oil,
grease, wax and other compounds which may inhibit bonding of
ElectraSeal to substrate.
C. Repair cracked and
eroded concrete in accordance with manufacturer's instructions.
Remove and repair unsound substrates.
3.3
APPLICATION
A. Mask all encumbrance such as
existing wall base and columns prior to application of coatings
in accordance with manufacturer's instructions.
B.
Install electrical grounding foil in accordance with
manufacturer's recommended grounding methods.
C.
Ensure that concrete or other substrate is visibly dry.
C. ElectraSeal is designed for use as supplied. Do not add thinners to any component of this
conductive floor coating system.
D. Apply 1st coat of ElectraSeal to prepared concrete per
manufacturers recommended guidelines. Allow to cure for at least
1 hour prior to proceeding.
E. Apply 2nd coat of ElectraSeal per manufacturers recommended
guidelines. Allow to cure at least 1 hour prior to proceeding.
F. Apply 3rd coat of ElectraSeal per manufacturers recommended
guidelines. Allow coatings 1 hour to dry before subjecting to
foot traffic and 24 hours prior to subjecting to moderate
forklift traffic.
3.4 TESTING
A. Allow floor to cure 7 to 10 days and test flooring to
recommendations of ANSI/ESD S20.20-2007 per methods
ANSI/ESD S 7.1 (electrical resistance point to point and
electrical resistance to ground) and ESD/STM 97.1 (combination
resistance of flooring, technician and footwear).
3.5 PROTECTION
A. The ElectraSeal system gains hardness and conductivity
during a curing phase lasting 48 hours. Protect
floor coating system while curing and especially during move in
of heavy equipment.
