PART 3 - EXECUTION
3.1
PREPARATION
A.
Obtain Architect's approval of mock-up before installing flooring.
B.
Prior to installation of structural floor slab, advise General Contractor, in
writing, of all requirements of concrete substrate regarding finish, level
tolerance, and curing.
C.
Locate all flexible joints required.
D.
Preparation of Surface:
1.
After concrete curing period (28 days minimum) has elapsed, 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. 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.
Verify that moisture content is within range acceptable to flooring
material manufacturer using calcium chloride test per ASTM F1869
and/or relative humidity probe test per ASTM F2170.
4.
Prepare surface as required by manufacturer's printed instructions.
Preferred surface preparation is steel shot blasting or similar
mechanical method.
5.
Air Drying: After completion of cleaning, allow concrete surface to air
dry thoroughly prior to application of the floor surfacing. Blowers or oil
free compressed air may be used. Do not use flame-drying methods.
Prior to application of surfacing, the concrete surface shall be tested
for excessive moisture vapor transmission in at least two locations.
Place rubber mats at each location with smooth side against concrete.
Polyethylene with all edges taped may be used in lieu of mats. After
16 - 24 hours, remove mat or sheeting and examine the floor surface
for moisture accumulation. If tests indicate an accumulation of
EPOXY FLOOR SYSTEMS

moisture at either location, additional air-drying shall be undertaken
until such time as additional tests show no moisture accumulation.
3.2
3.3
Treat cracks in concrete using manufacturer's recommended practice.
Rout out crack and joints, and fill with semi-flexible epoxy; coat with
flexible
membrane
in
accordance
with
manufacturer's
recommendation to prevent cracking through flooring system.
7.
Remove plastic void cap at the top of the expansion joint material
placed at the perimeter of the concrete slabs. Clean joint of all foreign
material.
INSTALLATION
A.
Install all floor materials in strict conformance with manufacturer's instructions.
B.
Install a screed line or termination strip at all color transitions except at stripes
where a masked edge topcoat of a different color shall be installed.
C.
Elastomeric membrane, if required, at concrete slab applications and where
indicated. Install in single or multiple coats to a minimum dry film thickness of
25 mils.
D.
Once self-leveling broadcast epoxy materials have cured remove excess
broadcast sand from floor surface.
E.
Match finished work to approved samples, uniform in thickness, sheen, color,
patterns and texture, and free from defects detrimental to appearance.
F.
Install flexible joint filler at all perimeter expansion joints where concrete slab
abuts vertical wall assembly. Color of filler to match floor system.
G.
Install flexible epoxy joint sealant in all saw cut and cold joints.
H.
Apply temporary protection until floor is fully cured.
INSPECTION
A.
3.4
6.
Touch up and repair all work that is not acceptable to Architect and request
final acceptance.
CLEANING
A.
Remove coating spatters from glass, plumbing fixtures, and adjoining
surfaces.
B.
Repair any damage to coating or surfaces caused by cleaning operation start.
C.
Remove debris from job site and leave storage area clean.
