About this file
This document is a Technical Data Sheet for CrackMaster 1190, a hot pour crack sealant product manufactured by SealMaster, a pavement products and equipment company. The document provides detailed technical specifications and application guidelines for a single-component, hot applied sealant designed for use in both asphaltic and cementitious pavements, meeting industry standards such as ASTM-D1190, ASTM-D6690 Type I, and AASHTO-M173.
The product is a black, solid block sealant composed of asphaltic resins and synthetic polymer rubber, intended for sealing expansion joints, longitudinal and transverse cracks, and random cracks in asphalt and concrete pavements. It is recommended for application at temperatures between 370-390°F, with specific technical requirements including a cone penetration of 90 max at 25°C, resiliency of 30-60%, and a flow of 5 mm max at 140°F. The technical data sheet provides detailed installation instructions, safety precautions, and a material requirements chart that estimates pounds of sealant needed per 100 feet of cracks based on crack width and depth. The product is available through a nationwide network of SealMaster facilities and professional applicators.

PRODUCT DESCRIPTION
CrackMaster 1190 is a single component, hot applied crack and joint sealant. When melted and properly applied it forms a resilient crack sealant for both asphaltic and cementatious pavements. CrackMaster 1190 meets ASTM-D1190, ASTM-D6690 Type I, and
AASHTO-M173.
USES
CrackMaster 1190 is designed to seal expansion joints, longitudinal and transverse cracks, joints between concrete and asphalt shoulders, and random cracks in both asphalt and concrete pavements.
COMPOSITION
As supplied, CrackMaster 1190 is supplied in solid blocks comprised of asphaltic resins and synthetic polymer rubber.
COLOR
Black.
LIMITATIONS
Do not overheat material. Cracks must be free from moisture, dust, loose aggregate and other contaminates prior to application.
TECHNICAL DATA
CrackMaster 1190 meets the following material requirements when tested in accordance with ASTM D1190, ASTM D6690 Type I and AASHTO M173 (see chart below).

Asphalt Compatibility Passes
Viscosity @ 370 35 + 20 poise
ENVIRONMENTAL CONSIDERATIONS
CrackMaster 1190 is considered a non-hazardous material.
INSTALLATION
Proper surface preparation will facilitate adequate adhesion and consequently the maximum service life of the sealant. The crack must be free from moisture, dust, and loose aggregate. Routing or wire brushing are preferred methods followed by a compressed air heat lance immediately prior to sealing. The substrate and air temperature must be above 40°F.
METHODS
CrackMaster 1190 shall be melted in a conventional oil-jacketed unit equipped with an agitator and temperature control device for both material and heat transfer oil. Carefully insert blocks of material (with plastic bag) into melting equipment with agitator turned off. Load material slowly to avoid splashing.
After the initial load of material has reached the recommended pouring temperature (370-390°F), fresh material may be added as sealant is used. Melt only enough material that will be used the same day.
Avoid overheating material. Excessive heat could cause material to gel in the equipment or fail in crackand joints. A significant viscosity increase accompanied by stringiness signals the approach of gelation. If this occurs, immediately remove the material from the melter and dispose of it.
IMPORTANT
Protective apparel is recommended with application of CrackMaster 1190. The extremely hot material will cause severe burns on contact with skin. OSHA Safety Regulations require workers to wear the following types of safety attire (see current OSHA/Safety Regulations for additional information): Hard hat with face shield; long sleeved shirt buttoned at the wrist; heat resistant gloves;
long, cuffless pants; and safety toed work boots. Make certain all area around melter is clear of all debris and flammable materials. Avoid breathing vapors. Use with adequate ventilation.
MIXING PROCEDURES
Use material as supplied. Do not blend with other materials. After CrackMaster 1190 is melted it should be agitated or recirculated.
APPLICATION
Apply heated CrackMaster 1190 using either a pump and wand system or a pour pot. For best results the sealant depth to width ratio should not exceed 2 to 1 (i.e.
2-inches deep to 1-inch wide). The cooled sealant height should not exceed 1/8” above surrounding pavement.
Using a sealing shoe or squeegee, band the material 2 to 3 inches wide over the crack.

Technical Data Sheet
CRACKMASTER 1190
Hot Pour Crack Sealant material requirements (based upon pounds of material needed for 100 feet of cracks):
Crack Width Depth Lbs/100 Ft
3/8” 3/8” 6.9 lbs.
3/8” 1/2” 9.3 lbs.
1/2” 1/2” 12.3 lbs.
1/2” 1” 24.7 lbs.
3/4” 1/2” 18.5 lbs.
3/4” 3/4” 27.8 lbs.
The above coverage rates are only a guideline. Actual material usage may vary due to width of application and thickness of material above pavement surfaces.
PRECAUTIONS
Cracks must be free from moisture, dust, dirt, and debris.
Both substrate and air temperature must be above 40°F.
Keep boxes of material dry during storage. Do not store in direct sunlight.
PACKAGING AND AVAILABILITY
CrackMaster 1190 is supplied in both meltable packaging and cardboard cartons. CrackMaster Hot Pour Crack Sealants are supported by a nationwide network of SealMaster facilities along with a national and international network of professional applicators.
