Abstract: An apparatus for placement of seam tape to a roof or roof membrane. The apparatus comprises first and second sides spaced a distance apart, wherein each side includes a material axle opening and a pressure applicator orifice. The apparatus also comprises a removable pressure applicator having a first end and second end positioned in the pressure applicator orifices of the first and second sides. A support element may be operatively attached to the first and second sides, span the distance between the first and second sides, and positioned opposite the pressure applicator to support the apparatus. Additionally, a material axle may be positioned such that its ends are removably positioned in the material axle openings of the first and second sides. A closed front side may connect the first and second side, while an open stern may allow direct access to the pressure applicator, the support element, and the material axle.

Abstract: An adhesive composition comprising a solids component, said solids component including a rubber component that includes polychloroprene; and a solvent component, said solvent component including t-butyl acetate.

Abstract: A method of adhering a roofing membrane to a roof surface including providing a roofing membrane including a hygroscopic dusting agent on at least one planar surface of the membrane. A water-borne adhesive is applied to the at least one planar surface of the membrane or the roof surface and the roofing membrane is then mated to the roof surface while the adhesive retains a majority of its original water content.
