PART 2 - PRODUCTS
2.01 MATERIALS
A. System
Overview
1. The coating system shall be Epoxy.com High-Build Coating System using
Epoxy.com #899 Primer/Low Modulus Binder, and two (2) coats of
Epoxy.com
#1 100% Solids Epoxy Coating. This system shall be applied over a clean,
well prepared substrate. See manufactures Surface Preparation
Guide at www.epoxy.com/surfaceprep.aspx
for additional information.
2. Prior to system application, all control joints and cracks
are to be treated with semi-rigid epoxy joint filler and rigid epoxy crack
filler respectively as described in the execution section.
3. The finished floor
system shall be a minimum 20 - 30 mils in thickness, dense, nonporous and have a
gloss finish with light non-skid texture matching approved sample.
B. Cracks and non-expansion joints shall be routed and filled with
Epoxy.com
Product #2704 and Epoxy.com Product #11 Epoxy Joint Filler respectively.
PART 3 - EXECUTION
3.01
PREPARATION
A. Obtain Architect's approval of mock-up before installing
flooring; see QUALITY ASSURANCE in PART 1.
B. Preparation of Surface:
1. Inspect
surfaces to receive flooring and verify that condition is smooth and free from
conditions that will adversely affect execution, permanence, or quality of work.
a. Remove all projections, all debris detrimental to flooring system, and dirt,
oil contaminates, grease, and surface coatings affecting bond.
2. Notify
Architect in writing prior to commencing work of any conditions deemed
unsatisfactory for the installation; installation of flooring materials is
understood as acceptance of the substrate as satisfactory.
3. Concrete: The
General Contractor shall be responsible for hiring an independent testing
service to test for moisture content and moisture vapor emission rate; install
no flooring over concrete until the concrete has been cured and is sufficiently
dry to achieve permanent bond with flooring as determined by material
manufacturer's recommended bond and moisture tests.
a. Effectively remove
concrete laitance by steel shot blasting or other method approved by flooring
manufacturer and achieve minimum surface profile of CSP-3.
b. Concrete slab
shall have an efficient puncture-resistant reinforced moisture vapor barrier 10
mils thick minimum directly under the concrete slab (for slab on grade). Do not
use vapor barrier manufactured with recycled material. Testing must be done to
verify that the moisture vapor emission rate of the slab does not exceed that as
recommended by the manufacturer at time of installation of the flooring or at
any future date. Moisture vapor emission and moisture content testing must
conform with the requirements of ASTM F-1869-11 (Calcium Chloride Test) and ASTM
F-2170-11 (Relative Humidity Probe Test). If any test result shows excessive
levels of moisture content or vapor emission rate, apply manufacturer�s
recommended moisture vapor emission control material based on the highest
reading.
C. Cracks and non-expansion joints shall be routed and filled with
Epoxy.com Product #2704 Super
Fast Setting Epoxy Crack Filler) and Epoxy.com Epoxy Joint Filler
#11 respectively.
3.02 APPLICATION

General Apply each component of the Epoxy Coating System in compliance
with manufacturer's installation instructions including mixing and application
methods, recoat windows, cure times and environmental restrictions. The system
is to be applied directly over all non-expansion joints and cracks that have
been treated as previously described. Material applied over properly treated
expansion joints, control joints, or moving cracks is subject to cracking or
other physical stress if there is movement in the joint or crack.
B. Cracks and Non-Expansion Joints
1. Cracks less than 1/16" wide after surface preparation shall be filled
with Epoxy.com #2704
or other resin approved by Manufacturer, mixed and applied as
recommended by the manufacturer's printed instructions. All treated
cracks are to be sanded prior to applying primer. Non-Expansion Control
(Contraction) Joints shall be routed and filled with Epoxy Joint Filler
#11 semi-rigid epoxy.
2. Those cracks larger than 1/16" wide shall be filled
with Epoxy.com #2704 or other resin approved by
Manufacturer, mixed and applied as recommended by the manufacturer's printed
instructions.
C. Epoxy Primer
Apply epoxy primer Epoxy.com #899 at the rate of 250 square feet per gallon to thoroughly wet surface, but
taking care not to "pond" the material. If using alternate primer or moisture
vapor control system approved by Manufacturer, follow mixing and application
instructions.
D. Coating Application
1. Apply 2 coats of
Epoxy.com #1 at a minimum total thickness of 16 mils.
200 square feet per gallon is
required coverage for 100% solids epoxy coating to achieve 16 mils thickness.
2.
Follow manufacturer's instructions for mixing and application techniques.
3. Add
during mixing or broadcast non-skid grit into epoxy coating application to
provide required textured finish if specified.
E. Obtain architect/engineer's approval of the
system just after completion of the final coat, prior to completion of curing.
3.03 CURING AND PROTECTION
A. Cure High-Build Epoxy/Urethane Coating System
