Application

Apply AIM #890 Neoprene as it comes from the container with either a trowel or caulking gun. Surface must be free of oil and dirt. AIM #890 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. If the product is over-applied on EPDM roofs, temporary swelling may occur. Do not use this product as a shingle tab cement.
