NOVACAULK #2 has the same properties as Novacaulk #1, plus it has
been fortified with unique fibers so that when cured, the resultant film
actually becomes a non-woven fabric. This feature makes it especially suited
for treating cracks on tennis courts when applied over Novacaulk #1.
The Novacaulk system will
tolerate movement of the pavement on both sides of a crack. As a crack
becomes wider, the Novacaulk repair will actually elongate and the top layer
acts as a bridge over the crack. Conversely, as a crack closes, the elastic
properties of this system allow the entire crack repair to close with it.
Clean crack so that it is free of all vegetation and
debris. Remove all lost pavement from crack.
Install backer rod (must be wider than crack) into
crack, top of rod 3/16” below surface or fill crack with clean sand to
within 3/16” of surface
Using a broad knife, squeegee rubber, or similar tool,
fill crack to refusal with Novacaulk #1. It is important to exert some
pressure when placing the Novacaulk into the void so that the material
comes in contact with the walls of the crack.
Allow the Novacaulk to set. (4 hours during ideal
drying conditions - longer when damp or cool).
Apply a coat of Novacaulk #2 over the crack. This coat
should be thicker directly over the crack and taper to a feather edge.
This application should be wider than the actual crack by 3 to 6 inches on
both sides. Extremely wide cracks my need a second application of
Novacaulk #2 and probably the repair should extend further out to the
side. Novacaulk #2 is easily spread with a squeegee when first placed on
the pavement. If, after a few minutes, it becomes difficult to spread
smoothly, sprinkle a few drops of water over the repair. This will make
the material easier to smooth.
Allow repair to dry and coat with Novacrylic color
system of your choice.
NOTE: Nova Sports USA does not guarantee the results
of any repairs using these products.
Cracking of pavement is caused by many factors, most of which are not on
the surface of the pavement. Because of this, Nova Sports USA does not
represent the Novacaulk system as a cure-all for cracked tennis courts.
However, we feel that these products have gone a step beyond what has been
available until now, in both methods and expected performance. Most minor
cracks treated with this method should never appear again. Some major cracks
will be permanently repaired, and some of them will reappear, but as
smaller, less troublesome cracks. We expect that the use of these products
will enable owners to use existing cracked tennis courts that would
otherwise have to be ripped out or treated with a more costly overlay type
