3.00 EXECUTION
3.01 Installation Procedure
a. If new concrete is to be poured, the sub-grade should
be prepared in accordance with the recommendations
of the soils engineer and the American Concrete
Institute. The reinforcement should be placed in
accordance with the guidelines of the American
Concrete Institute. The concrete should be placed and
finished in accordance with accepted industry
standards. The concrete should be allowed to cure for a
period of at least 28 days prior to the application of the
stain(s). Liquid membrane cures or plastic sheeting
should not be used. The new concrete should be cured
using either curing paper or wet curing methods.
b. Optional: Bomanite Color Hardener shall be applied
evenly to the plastic surface by the dry-shake method
using a minimum of 60 pounds per 100 square feet
(27.2 KG per 9.3 square meters). It shall be applied
in two or more shakes, floated after each shake and
troweled only after the final floating.
c. Optional: The Licensed Bomanite Contractor shall
provide all decorative jointing and finishes in designated
areas and in accordance with the Architect’s direction.
d. The contractor shall patch and repair all defects in the
surface.
e. The substrate shall be free of all debris, oils, grease,
curing compounds, sealers, etc. prior to the
application of the chemical stain(s) and/or sealer(s).
f. To stabilize “dusty” or soft surfaces due to improper
curing/finishing techniques and provide waterproofing
protection against moisture problems, apply Bomanite
Con-Shield per manufacturer’s recommendations. (See
Bomanite Con-Shield Technical Bulletin)
g. If concrete slabs have been burnished with finishing
machines and are found to be highly polished,
lightly etch the surface using Bomanite Con-Clean
prior to the staining application.
h. Optional: Bomanite Chemical Stain shall be applied
to the clean substrate in a minimum of two coats at a
rate of 300 to 600 square feet (18.6 to 37.2 square
meters) per
applied in accordance with the manufacturer’s
recommendations. (See Bomanite Chemical Stain
Technical Bulletin)
i. Optional: Bomanite Con-Color shall be applied to the
clean (free of cures, sealer, etc.) substrate in
accordance with the manufacturer’s recommendations.
(See Bomanite Con-Color Technical Bulletin)
j. The surface shall be sealed using Bomanite Sealer in
accordance with the manufacturer’s recommendations
to complete the coloring process.
