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 four years.
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.
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 hand cleaner.
PAVISEAL is available bulk and in package sizes of 5 gallon pails and 55 gallon drums.
