13. A method of tending a wound, the method comprising:
- retaining opposing edges of a wound together by adhering one or more wound closures to skin on opposing sides of the wound, each wound closure of the one or more wound closures comprising a backing, a layer of adhesive on one major surface of the backing, and a wound bridging portion, wherein the wound bridging portion of each wound closure of the one or more wound closures contacts the opposing edges of the wound, and wherein the wound bridging portion of each wound closure of the one or more wound closures in contact with the opposing edges of the wound comprises microporous polypropylene film; and
applying flowable adhesive skin paint to the wound adjacent the one or more wound closures after adhering the one or more wound closures across the wound using the layer of adhesive on the one or more wound closures, wherein the adhesive skin paint comprises 1-40% of a siloxane-containing polymer;
60-99% of an Alkane-Based Siloxane Polymer Reaction Solvent; and
0-15% of adjuvants;
wherein adhesion strength between each wound bridging portion in contact with the opposing edges of the wound and skin is about 30 grams/centimeter or less.

Abstract
Methods and systems for closing wounds using wound closures and a flowable adhesive skin paint are disclosed. The flowable adhesive does not adhere the wound closures to the skin over the wound to reduce irritation. In some embodiments, the skin paint may include 1-40% of a siloxane-containing polymer; 60-99% of an Alkane-Based Siloxane Polymer Reaction Solvent; and 0-15% of adjuvants. The wound closures used with such a skin paint may include a wound bridging portion of microporous polypropylene film.
