Lucas Seam Sealer 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 Seam Sealer is ideal for caulking termination bars, metal flashings and fasteners. #5500 is strong, elastic, and adheres to most common roofing materials. It is manufactured in two grades. #5500G is a fluid ‘gun grade’ intended for pump and wand application. #5500M is a semi-selfleveling brushable mastic viscosity.
Lucas Seam Sealer is manufactured from a 100% synthetic rubber base to a mastic or semi-mastic viscosity. It contains no asphalt or other bituminous material. Lucas #5500 is formulated to apply easily by trowel, brush or caulking gun. Lucas #5500 contains anti-oxidants and light-stabilizers for extended life and reinforcing fibers that add strength and durability.
Apply Lucas #5500 Seam Sealer as it comes from the container with a trowel, chip brush or caulking gun. Surface must be free of oil and dirt. Lucas Seam Sealer will adhere to wet and underwater surfaces when used for repairs only. Apply ¼ inch thick and taper edges when possible. When using a caulking gun apply a bead ¼ to ½ inch thick. For single-ply systems, consult the manufacturer to insure compatibility.
Lucas #5500 may be left exposed or top coated with Lucas #6000, #5000, #3000 or any Lucas Aluminum Roof Coating.
