Questions about this item

What roof surface must I have before applying this 3.5 gal pail?

It bonds to composition, mineral cap sheet, asphalt coated, SBS modified and metal roofs when applied at room temperature.

Can I brush it over an older asphalt coating that is still sound?

Yes, the asphalt-based formula adheres to existing asphalt coated and SBS modified roofing without stripping the old layer.

How do I confirm the repair has cured properly?

The matte black finish reaches full cure after 30 days; until then the surface remains tacky and should not be walked on.
