GraniteSeal utilizes a unique formula consisting of the highest quality additives. Each component was selected to produce a sealcoat with deeper and longer-lasting color, firmer body, and greater durability than many other products available. In addition, GraniteSeal is free from asbestos fillers or any other carcinogenic material and is nonflammable.
GraniteSeal is compatible with asphalt pavement. The coefficient of expansion of GraniteSeal is identical to that of asphalt pavement and has a natural affinity for bonding to the pavement.
To ensure a long-lasting, quality job, follow these simple guidelines:
CLEAN AND FILL CRACKS
Clean and treat with weed killer all cracks 1⁄8 inch and larger. Then fill with TA-300 S/M crackfiller. (Large cracks may require several applications.) For best quality, it is recommended that all broken asphalt be removed and patched with new asphalt. It is also suggested that extreme low spots be filled with new asphalt. New asphalt should cure 30 days before application of GraniteSeal.
OIL AND GREASE
Because sealcoats will not adhere to surfaces with excessive oil and grease, these deposits should be cleaned with a stiff bristle broom or power-operated broom using a degreasing solution. It is, however, recommended that areas completely saturated with oil be removed and patched with new asphalt. If this is impractical, the surface should be treated with a TA-1000 sealer, which will assist in the adhesion of the sealcoat.
FINAL SURFACE CLEANING
After pavement repairs, the surface should be cleaned of all dirt and loose or raveled particles of existing pavement. (Dirt will restrict the adherence of the seal coat.) This is best accomplished by a power broom, power blower or by flushing with high pressure water.
For best results, the asphalt, just prior to being sealed, should be sprayed with a mist of water in an amount that will leave the surface damp but with no puddles or visible water. This procedure is critical when the ambient temperature is hot with bright sunlight or when the pavement is excessively aged or porous. In these two instances, the pavement will draw the water out of the seal coat at too rapid a rate unless prewatered.
Priming may be necessary on surfaces that have weathered excessively or are dusted. The primer should be diluted with 5 parts clean water to 1 part SS1-H. Apply at the rate of 1 gallon per 100 square feet and allow to dry. If in doubt, a test patch should be tried.
GraniteSeal may be mixed with water to obtain desired consistency for job requirements to a maximum of 20% dilution. Care should be taken not to over-dilute. Note that as the pavement increases in roughness, the amount of dilution should be decreased.
Apply GraniteSeal using a truck-mounted tank, wheeled container, or can. Spread in continuous parallel lines by means of rubber-faced squeegees or by broom. This can be done by hand or machine. Tools should be wet before use. After material is applied to surface, the GraniteSeal should be spread by pulling the material toward operator in a manner that will eliminate all ridges and air pockets.
When first coat has completely dried, apply the second coat. While misting is not normally required before second coat, surface should be clean with no foreign materials on it.
GraniteSeal should be allowed to dry 24 hours before permitting heavy traffic.
NOTE: When asphalt is cold or in shade, or air temperature is below 75°F, drying time may need to be extended.
Minimum application temperature: 55°F and rising.
Striping for parking or traffic flow should be done only after the sealcoat has thoroughly dried. It is recommended that a high quality water based Traffic Line Paint be used.
RECOMMENDED APPLICATION RATES
Proper application rates depend greatly upon the type and condition of the pavement. Porous or very old pavement absorbs a greater amount of the seal coat, therefore requiring more material. Also, where there many rocks exposed in the pavement, a greater depth of seal is required to cover these rocks.
The following rates (before dilution) for two coats may be used as guidelines only, as exact coverage depends upon both the condition of existing pavement and the surface condition desired after application.
