What is the Solids Content of Enduris Silicone Roof Coating?

The correct answer is C. Enduris is High Solids coating and cures to 90% of its installed thickness.

Which is NOT a characteristic of Enduris?

The correct answer is A! Enduris silicone roof coating cures chemically, while acrylic coatings are water-based and cure by evaporation.

True or False: A primer is needed before installing Enduris on rusted metal roofs.

The correct answer is False. Enduris stops the rust cycle and can be applied directly to rusted metal roofs. The roof just needs to be clean dry.

True or False: If there are two existing roofs, at least one must be torn off before installing a coating.

The correct answer is False. Roof coating is considered a maintenance item so code does not require that the roofs be torn off prior to coating application.

Which substrate is NOT acceptable to install Enduris roof coating?

The correct answer is B! Silicone and aluminized coatings do not work together.

True or False: A moisture scan is required on all roof types prior to coating.

The correct answer is False. A moisture scan is required on membrane roofs such as EPDM, TPO, PVC, modified bitumen, etc. if there is roof insulation or cover board under the membrane. Metal roofs do not require a moisture scan.

The correct answer is B!

True or False: Performing the painter's tape test can help determine if a roof is clean and dry enough to apply coating.

For a metal roof, what is the required wet film thickness of Enduris Liquid Flashing on the horizontal seams.

The correct answer is D! Metal roofs require 60 wet mils of liquid flashing on the horizontal laps while membrane roofs require 40 wet mils on all laps and seams.

The correct answer is D! Contractors should use a Wet Mil Gauge to check the Wet Film Thickness regularly while the coating is being installed.

When performing adhesion test, how many pounds of resistance is required?

The correct answer is B! So, if you’re using a 4-inch width of fabric to do the testing, then you need a minimum of 8 pounds of resistance.
