Lucas #304 Roof & Foundation Coating – Non-Fibrated provides an economical means of re-coating and preserving smooth-surface asphalt roofs. Periodic re-coating of otherwise sound built-up roofing felts can prolong service life many years. This product is not intended for use over tar or asphalt and gravel roofs. Please refer to our #010 for tar roofs and #713 for asphalt and gravel roofs. #304 is also recommended as a damp-proof coating for new poured foundation walls.
Lucas #304 is formulated from refined asphalt and petroleum solvents. Consistency is maintained to provide easy brushing qualities. All Lucas asphalt roof coatings are ready to use and do not require special preparation before use.
Surface to be coated must be clean and dry. Weak, broken, cracked or blistered areas of the roof and flashing must be repaired prior to coating with #304. Blisters, which are caused by trapped moisture, must be opened and dried, then resealed using glass membrane and flashing cement. Moisture trapped between plies of a roof will eventually reappear as a blister or a leak. Apply #304 evenly, as it comes from the container with any appropriate tool, preferably, a four knot roofing brush, at the rate of approximately one to two gallons per 100 square feet for a thickness of 11 to 23 dry mils on roofing applications. Do not allow foot traffic until the coating is fully cured.
Shelf Life: 2 years minimum.
