Environmental Considerations
SealMaster Coal Tar Concentrate does not contain asbestos. Coal Tar Concentrate is an environmentally friendly water based pavement sealer containing less than 50 grams per liter volatile organic content (VOC).

Physical Chemical Properties
SealMaster Coal Tar Concentrate is a premium quality pavement sealer that meets the following material requirements when tested in accordance with ASTM D 140, ASTM D 466, ASTM D 490, ASTM B117, ASTM D 529, ASTM D 2939, and ASTM D244 procedures. (see chart below)

Installation
Surface must be clean and free from all loose material and dirt. Pavement surface repairs should be made with a suitable hot or cold asphalt mix. Cracks should be filled with SealMaster hot pour or cold applied crack fillers. Treat all grease, oil, and gasoline spots or stains with SealMaster Petro Seal™ or Prep Seal™.

Methods
SealMaster Coal Tar Concentrate shall be applied by either pressurized spray application equipment or self-propelled squeegee equipment. Pressurized spray equipment shall be capable of spraying pavement sealer with sand added. Equipment shall have continuous agitation or mixing capabilities to maintain homogeneous consistency of pavement sealer mixture throughout the application process. Self-propelled squeegee equipment shall have at least 2 squeegee or brush devices (one behind the other) to assure adequate distribution and penetration of sealer into bituminous pavement. Hand squeegees and brushes shall be acceptable in areas where practicality prohibits the use of mechanized equipment.

Mixing Procedure
For optimum results, SealMaster Coal Tar Concentrate Pavement Sealer shall be mixed in accordance with the following mix design (based on 100 gallons for ease of calculation):
Coal Tar Concentrate …………………………………100 gallons
Water ……………………………………………………….20-40 gallons
Pave Gel Polymer Additive …………………………..1-2 gallons
Sand* ………………………………………………………….200-500 lbs.
*(40-70 mesh AFS rating)

Important
The above mix design is a typical recommendation. Alternative mix designs may be substituted to account for local pavement conditions and use of other pavement sealer additives. However, in all cases sand shall be used in the mix design.

Note
Pave Gel is manufactured by ThorWorks and is available from your local SealMaster facility.

Application
For optimum performance and durability apply two coats of properly mixed SealMaster Coal Tar. A third coat of mixed Coal Tar Sealer may be applied to high traffic areas such as entrances, exits, and drive lanes.

Application Rate of Mixed Coal Tar Sealer
Apply properly mixed Coal Tar Sealer (Coal Tar Concentrate, Water, Sand, Additive) at a rate of .11 to .13 gallon per square yard (70-82 square feet per gallon) per coat.

Estimating Material Requirements
To estimate gallons of SealMaster Coal Tar Concentrate required to cover a specific area use the following coverage rate:
• One gallon of SealMaster Coal Tar Concentrate will cover approximately 100-120 square feet (11.1 to 13.3 square yards) per coat when properly mixed and applied.

Note:
Coverage rates may vary due to pavement age and porosity.

Precautions
Both surface and ambient temperature shall be a minimum of 50ºF in a 24 hour period following application. New asphalt surfaces should be allowed to cure a minimum of four weeks under ideal weather conditions (70ºF) before applying Coal Tar Concentrate. Keep out of reach of children. Do not store unopened drums or pails in freezing temperatures.
