Lucas 721 Asphalt Emulsion Roof Coating Fibrated 5 Gallon:

What's it for?
#721 Asphalt Emulsion - Fibrated is a water-based asphalt protective coating for built up asphalt roofing and concrete foundation walls. Asphalt emulsions are faster drying, very low odor alternatives to solvent borne asphalt roof coatings such as Lucas #714. Asphalt emulsions are often used to fill in and even out ‘alligatored’ areas on asphalt built-up roofs.

What's in the bucket?
Lucas #721 Asphalt Emulsion - Fibrated is manufactured from refined asphalts, reinforcing fibers and colloid clays. #721 has a brown appearance when wet but will dry to a near black color.
