Abstract
A method includes obtaining a spray device having a pump and a container containing an adhesive composition that does not include a propellant, operating the pump to pressurize the adhesive composition in the container to a pressure of 1 psi to 200 psi, spraying the adhesive composition from the container onto a roofing substrate to form an adhesive layer on the roofing substrate, and applying a roofing material to the adhesive layer on the roofing substrate.
Claims20
A method comprising:
- obtaining a spray device,
- wherein the spray device comprises:
- a pump;
- and
- a container,
- wherein the container contains an adhesive composition,
- wherein the adhesive composition does not comprise a propellant;
- wherein the adhesive composition has a viscosity of 2000 cP or less, when measured at a temperature of 25° C. using a Brookfield viscometer with a spindle #2 and a viscometer speed of 20 RPM for 1 minute;
