After the surface has been properly prepared, GuardTop Seal Coat can be applied. GuardTop can be mixed with water to obtain a desired consistency for the job requirements. The maximum dilution for the product is 20% water to 80% GuardTop. Please note that care should be taken not to over dilute the product. As pavement increases in roughness, the amount of dilution should be decreased. GuardTop should be applied in the following steps.
1. First Coat
Prior to applying the first coat, mist the surface with water. Then apply GuardTop using a truck mounted tank, wheeled container, or can. Spread in continuous parallel lines by means of rubber-faced squeegees or by broom. This process can be completed by hand or by machine. All tools should be misted wet before use to avoid product adhesion. After material has been applied to the surface, the GuardTop should be spread by pulling the material toward the operator in a manner that will eliminate all ridges and air pockets.
On excessively rough areas: for the first coat add 3 pounds of 30 mesh sand to each gallon of GuardTop and 1/10 gallon of GuardTop Hard Base Emulsion. Apply as a normal first coat. Then apply two additional coats of GuardTop without the sand additive to the surface.
2. Second Coat
After the first coat has completely dried, re-mist the surface with water, check to see that the surface is clean and free of all debris and apply the second coat using the same application process as the first coat. If a third coat is required repeat this step.
3. Drying Time
GuardTop should be allowed to dry a minimum of 24 hours before heavy traffic is permitted. Please note that when asphalt is cold, in shade or the air temperature is below 75 degrees drying time may need to be extended. GuardTop should not be applied in temperatures below 55 degrees.
4. Parking Lot and Traffic Flow Striping
Striping for parking or traffic flow should be completed only after the seal coat has thoroughly dried. It is recommended that a high quality water based traffic line paint be used for best results.
