Abstract
A chemically coated roofing membrane assembly includes a membrane and a chemical coating on at least a portion of one surface of the membrane. In one or more embodiments, the chemical coating may be provided along the top surface of the membrane adjacent to a longitudinal edge of the membrane, and along the bottom surface of the membrane adjacent to a second longitudinal edge of the membrane. The chemical coating is cured, and may be formed from acrylic or urethane chemical compositions. The chemically coated roofing membrane eliminates the need for in-field priming of the membrane.
Claims9
A method of installing a membrane assembly on a roof surface comprising:
- positioning a first membrane assembly on the roof surface, the membrane having a top surface, a first longitudinal edge, and a cured-coating layer along the first longitudinal edge of the top surface;
- positioning a second membrane assembly on the roof surface, the membrane having a bottom surface, a second longitudinal edge, and a cured-coating layer along the second longitudinal edge of the bottom surface, wherein the second membrane assembly overlaps the first membrane assembly;
- applying an adhesive tape to the cured-coating layer of one of the first membrane assembly and the second membrane assembly;
- and
- pressing the cured-coating layer of the other of the first membrane assembly and the second membrane assembly against the adhesive tape to form a lap seam between said first membrane assembly and said second membrane assembly.
A method of making a membrane having a cured-coating layer comprising:
- extruding a membrane;
- applying a coating composition to at least part of the membrane to form a coating layer;
- and
- curing the membrane and the coating layer to form a cured-coating layer on the membrane.
