1. A method of treating a wound, comprising:
providing a wound dressing;
removing a portion of the wound dressing to create a main wound dressing portion with an exposed portion,
positioning the main wound dressing portion over a wound;
dispensing a composition comprising a silicone curing system to the exposed portion of the main wound dressing portion thereby sealing the exposed portion, the composition shear thinning or shape conforming when subject to load such that the viscosity of the composition is reduced when the composition is subject to shear forces during dispensing; and
wherein the composition is configured to be drawn into a transmission layer by negative pressure prior to curing.
