1.2 SCOPE
OF WORK
A.
This
specification covers the construction and installation for:
(#)
Tennis courts at
(project name & location).
B. Tennis courts shall be cleaned using a stiff bristle broom and
gas powered blower or water based pressure spray unit capable of generating

PART
2 - PRODUCTS
2.1
TENNIS COURT SURFACE MATERIAL
A.
Tennis
Court Surfacing Materials shall be:
1. 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.
New
asphalt pavement shall cure for 14 days prior to application of any
surfacing materials.
B. Contractors must notify the Landscape Architect of all
applications, 48 hours prior to installation. 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.
D.
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.
E. 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.
F.
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.
G.
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.
H. Using a neoprene rubber squeegee, apply two (1) coat of
Novacrylic Combination Surface, diluted two (2) parts concentrated material
to one (1) part clean 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.
I.
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
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 50 degrees F.
and rising, and the surface temperature is not in excess of one hundred
forty (140) degrees 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.
