Lucas 100 Neoprene Rubber Sealant 10 oz. Tube Black

Lucas Neoprene Cement is a premium synthetic rubber based sealant and caulk. It is

intended for flashing, sealing and repairing metal roofs and trailers, built-up roofing, modified

bitumen, TPO and many other single ply systems. Lucas Neoprene is ideal for caulking

termination bars, metal flashings and fasteners. #100 is strong, elastic, and adheres to most

common roofing materials. Lucas Neoprene Cement may be used to caulk and repair EPDM

rubber roofs. #100 is black.

Lucas Neoprene Cement is manufactured from a 100% synthetic rubber base. It contains no

asphalt or other bituminous material. Lucas Neoprene is formulated to apply easily by trowel or

caulking gun. High solids content and light weight allow Lucas Neoprene to fill gaps up to 2”

wide and can be easily troweled and shaped as desired. Lucas Neoprene also contains anti-

oxidants and anti-ozonants for extended life and reinforcing fibers that add strength and

durability.

Apply Lucas Neoprene as it comes from the container with either a trowel or caulking gun.

Surface must be free of oil and dirt. Lucas Neoprene Cement will adhere to wet and underwater

surfaces. Apply 1/8 to 1/4 inch thick using a standard pointed roofer’s trowel. Feather all edges

of the repair. When using a caulking gun apply a bead at least 1/4 inch thick. For single-ply

systems, consult the manufacturer to insure compatibility. EPDM that is not fully adhered will

swell upon contact with this product. Do not use this product as a shingle tab cement. For a

shingle tab cement or modified bitumen adhesive refer to our #766 Elastomeric Cement.
