  • Patent number: 4966788
    Abstract: Paint is sprayed in a line onto a fiber glass mat just prior to the mat being impregnated with hot asphalt. The temperature of the asphalt causes the paint solvent to flash, the process of which prevents the asphalt from displacing the pigment, leaving the paint pigment in place in the body of the mat. A number of such lines may be formed on the mat at predetermined spaced locations to serve as installation guide lines for the roofer.
