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 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: BOMANITE Integral
Color shall be added to the concrete mix at a rate of one sack per cubic yard
and mixed at charging speed for 5 - 10 minutes. Slumps shall be between 4" and 5" (10.1 cm to 12.7
cm). Additional water should not be
added to the mix in order to achieve higher slumps. Higher slumps should be achieved by the use of water reducing or
plasticizing admixtures.
d. Optional: The Licensed BOMANITE Contractor shall
provide all decorative jointing and finishes in designated areas and in
accordance with the Architect's direction.
e. The
contractor shall patch and repair all defects in the surface.
f. 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).
g.
Optional: BOMANITE Chemical
Stain shall be applied to the clean substrate in a minimum of two coats at a
rate of 200 to 400 square feet (18.6 to 37.2 square meters) per U.S. gallon,
per coat. The stain shall be applied in
accordance with the manufacturer's recommendations.
h. The
surface shall be sealed using BOMANITE Sealer in accordance with the
manufacturer's recommendations to complete the coloring process.
