EMULSIFIED ASPHALT SEALCOATING
PAVISEAL is a mineral filled emulsified asphalt sealcoating engineered
to provide superior abrasion resistance along with improved sealing
ability to enhance and prolong the life of asphalt pavement.
PAVISEAL is designed for use on any asphalt pavement surface such
as parking lots, airports, driveways, bike paths, school yards and
walk ways. PAVISEAL was engineered to prevent detrimental damage
to asphalt pavement due to the damaging effects of the weather and
the sun. Rain, snow, ice and frost combined with ultraviolet light
can cause severe oxidation and deterioration of the binder allowing
the top fines to come loose thus exposing the course aggregate.
PAVISEAL seals and protects the asphalt pavement by replacing the
smooth surface of fines and binders necessary to protect the pavement
from the elements. PAVISEAL also returns the rich black appearance
of a new asphalt pavement.
Under normal ware and tear a properly applied application of PAVISEAL
should not require a reapplication of PAVISEAL for up to three to
Reapplication of PAVISEAL should be at the recommended rates. Regular
preventive maintenance can extend the life of asphalt pavement indefinitely.
PREPARATION OF THE SURFACE
The pavement surface to be sealed must be clean and dry prior to
application of PAVISEAL. All cracks larger than hairline in size
should be filled with a crack filler and any pot holes or alligatored
or broken up pavement should be repaired prior to application of
PAVISEAL may be applied like any other mineral filled sealcoat
product. No special training or equipment is required. PAVISEAL
may be squeegee or brush applied using standard hand tools. Sealcoat
application machines utilizing drag or rotary squeegees are recommended.
Spray application equipment may also be used providing the equipment
has a pump and piping system capable of handling mineral filled
materials. The application equipment must be in good working order
and contain no contaminants in the tank and piping systems.
The rate of application for PAVISEAL will vary depending on the
age, texture and porosity of the asphalt pavement. The recommended
application rate for PAVISEAL is 0.15 to 0.20 gallons per square
yard. Older or rough pavements may require a second application
of PAVISEAL to completely fill in the surface.
PAVISEAL is supplied in a concentrate form and should be diluted
prior to application. It is recommended that PAVISEAL be diluted
10 to 15% (1 part water to 6 parts PAVISEAL). After addition of
water, PAVISEAL should be mixed thoroughly until uniform.
PAVISEAL should not be applied to damp or wet pavement surfaces.
Do not apply during rainy or damp weather or when rain is anticipated
within eight (8) hours after application is completed. Pavement
temperatures should be 50° F and rising before application of
PAVISEAL is initiated. At least three hours of daylight should remain
after completing the application of PAVISEAL.
ADDITION OF POLYMERS
Cationic polymer modifiers may be added to PAVISEAL to enhance
adhesion, toughness and increase resistance to oxidation and improve
fuel resistance. It is recommended that the modifier be added at
a percentage of between 1% to 5%. Be sure to experiment to find
the right percentage rate to achieve the desired consistency. Thoroughly
mix PAVISEAL after addition of a polymer to achieve a product of
uniform consistency. CAUTION: DO NOT USE AN ANIONIC LATEX.
ADDITION OF SAND
PAVISEAL has been engineered to provide a premium sealcoat product.
Sufficient mineral aggregate has been added to the product to fill
surface voids and provide an antiskid surface. Sand may be added
to PAVISEAL to enhance these properties if desired. If sand is to
be added it should be clean; free of dirt, silt, clay, salts and
organic matter. Sands with the following gradations may be used:
15 - 85
2 - 10
0 - 2
STORAGE & HANDLING
PAVISEAL is a chemically stabilized mineral filled Cationic Asphalt
Emulsion and may be stored like any other mineral filled emulsified
product. Horizontal storage tanks equipped with centrally located
full sweep horizontal agitation should be used. PAVISEAL may be
sorted in non-agitated tanks but settling of the mineral fillers
can be expected. Positive displacement gear pumps capable of handling
abrasive materials are recommended. Diaphragm, progressive cavity
and piston pumps may also be used. Care should be taken not to mix
PAVISEAL with an Anionic or Coal Tar base sealer. This could result
in a reaction of the two materials with a result of the asphalt
and water separating in the mix or storage tank. Since any emulsion
can be damaged by freezing, PAVISEAL should be protected at all
times when the temperature drops below 40° F.
Cure time for PAVISEAL under normal conditions is normally two
to eighteen hours. However, cure time may vary depending on weather
conditions. On cool or humid days or in sheltered or shady areas
drying time may be longer. In two coat applications, allow the first
coat to cure before applying the second coat.
PAVISEAL that has not dried may be removed from hands and tools
by rinsing with water. PAVISEAL that has dried can be removed from
tools, equipment or curbs with mineral spirits or a good citrus
based cleaner and can be removed from hands with a good waterless
PAVISEAL is available bulk and in package sizes of 5 gallon pails
and 55 gallon drums.
