Novacrylic, as manufactured by Nova Sports U.S.A., 6
Industrial Rd., Bldg. #2., Milford, MA 01757. 800-USA-NOVA
2.
Approved equal
B.
All coatings shall be pure acrylic, containing no asphaltic
or tar emulsions, nor any vinyl, alkyd or non-acrylic resins.
The
color system shall be factory-mixed compounds requiring only the addition
of water at the jobsite except for the addition of sand to Novasurface®
.
All materials shall be delivered to the jobsite in sealed containers with
the manufacturer’s label affixed.
III.
PART 3 - EXECUTION
3.1
APPLICATION
A.
Vapor barrier must be installed prior to pouring concrete,
minimum 15-mil thick polyolefin geomembrane.
B.
No wax or curing agents that are not certified as coatable
shall be used.
C.
New concrete shall cure for twenty-eight days prior to
application of any surfacing materials.
D.
Concrete
shall have a medium broom finish.
E.
Contractors must notify the Landscape Architect of all applications, 48
hours prior to installation.
F.
Etch concrete with a Phosphoric Acid solution; allow to set
and flush completely with water.
G.
The surface to be coated shall be inspected and made sure
to be free of grease, oil, dust, dirt and other foreign matter before
starting work.
H.
The surface shall be flooded. Any ponding water remaining
that is deep enough to cover the thickness of a five-cent piece shall be
corrected using a patch mix consisting of Novabond®
, 50-mesh sand and
Portland cement, as per manufacturers directions. Depressions must be
primed with a 50% dilution of Novabond®
and water prior to patching.
I.
Application shall proceed only if the surface is dry and
clean and the temperature is at least fifty degrees (50°F) and rising, and
the surface temperature is not in excess of one hundred forty degrees
(140°F). Do not apply coatings when rain is imminent.
J.
Each coat in this system must dry completely before next
application. Between each coat, inspect entire surface. Any defects
should be repaired. Scrape surface to remove any lumps, and broom or blow
off all loose matter.
K.
Apply one (1) coat of CP761®
Concrete Primer,
diluted one (2) parts CP761 to (1) part clean water. Application may
be with squeegee, broom or roller. Allow CP761®
to
dry thoroughly.
L.
Using a neoprene rubber squeegee, apply one (1) coat of
Novasurface®
acrylic resurfacer, diluted with one (1) part clean water, to
two (2) parts Novasurface®
. Clean,
bagged sand shall be incorporated into the diluted Novasurface®
at the rate
of five (5) to ten (10) Lbs. per gallon. Sand gradation shall be 50 to
60-mesh. Allow application to dry thoroughly.
M.
Using a neoprene rubber squeegee, apply two (1) coat of
Novacrylic Combination Surface®
diluted two (2) parts concentrated material
to one (1) clean part water (colors to be designated by owner). Allow
each application to dry thoroughly. The quantity of water used in
diluting these coatings may exceed the quantity specified by only a small
amount and only if coatings are drying too rapidly. Permission of the
owner shall be obtained before adding additional water.
N.
Using a
neoprene rubber squeegee, apply one (2) coats of
Novacoat®
, diluted
one (1) part concentrated material to one (1) part clean water (colors to be
designated by owner). Allow application to dry thoroughly. The quantity of
water used in diluting these coatings may exceed the quantity specified by
only a small amount and only if coatings are drying too rapidly. Permission
of the owner shall be obtained before adding additional water.
3.2
LINE MARKINGS
A.
Upon completion and acceptance of the tennis surface, this
Contractor shall prepare and paint lines for tennis.
B.
All lines are to be applied by painting between masking
tape with a paintbrush or roller, according to U.S.T.A specifications.
C.
Prime masked lines with Seal-A-Line®
. Allow application to dry.
D.
Paint lines with Novatex®
textured line paint. Allow application to dry.
E.
Remove masking tape immediately after lines are dry.
F.
Protect adjacent areas and structures
(fences, posts, sidewalks, buildings, etc.), which
are not to be coated. In the event that
coatings are applied to above, remove immediately before drying is
complete.
3.3
COMPLETION
A.
Upon completion, the contractor shall insure proper removal
of all construction debris, surplus materials, empty containers and wash
water, and shall leave the site in a condition acceptable to the owner.
The court is to be left secure so as to prevent vandalism.
3.4
LIMITATIONS
A.
Apply coatings only when ambient temperature is
fifty degrees (50°F) and rising, and the surface temperature is not in
excess of one hundred forty degrees (140°F).
B.
All NOVACRYLIC®
coatings are waterborne and cannot cure in cold
temperatures or when subject to moisture. Care should be taken not to
apply coatings when rain is forecast or sudden drop of temperature is
expected. Climatic conditions such as very cool evenings and high dew
points dictate that work should be completed early in the day so the
coatings can be exposed to enough warm sunlight to form a film before
sunset. The opposite applies during times of high heat, low humidity and
drying breezes: under these conditions, work very early in the morning or
very late in the day. If the product seems to be drying too fast in hot
weather, mist the pavement with water to make the application easier.
Care must be taken to allow each application to dry thoroughly prior to
recoating.
