2. Heating the Tar

Tar boilers heat the tar to a specific temperature, which is typically between 250 and 300 degrees Fahrenheit. This temperature allows the tar to flow easily and penetrate the surface.

• Operate tar kettles or boilers to heat the tar to the proper temperature.
• Monitor the temperature of the tar to ensure it does not overheat or cool down too much.

3. Applying the Tar

Tar boilers use a variety of tools to apply the tar, including brushes, rollers, and sprayers. They must apply the tar evenly and smoothly to create a uniform coating.

• Apply tar to surfaces using brushes, rollers, or sprayers.
• Ensure that the tar is applied evenly and smoothly to create a uniform coating.

4. Smoothing and Finishing

Once the tar has been applied, tar boilers must smooth and finish the surface. This involves using tools such as trowels and screeds to create a level and even surface.

• Smooth and finish the tar surface using trowels and screeds.
• Remove any excess tar and clean up the work area.
