A method for applying a patch to a spacer discontinuity or other seal breach includes the step of applying pressure to the patch during the application of the patch to cause sealant carried by the patch to be injected into the spacer discontinuity. This step can be performed with or without the application of heat. Pressure is applied to the patch long enough to position the sealant entirely across the gap between the lites such that the sealant wets out against both interior glass surfaces. Pressure is also applied to the patch long enough to inject sealant into openings defining the discontinuity. A sealant is then applied over the entire patch. The structure of the patch and the patched IG unit are provided.
