A method of plugging a honeycomb body is disclosed herein, the method comprising: contacting a first end of the honeycomb body comprising a plurality of channels with a light curable sealing mixture such that an infiltrate of the light curable sealing mixture flows into the plurality of channels proximate the first end; emitting a light toward a first portion of the infiltrate within the plurality channels of the filter; and curing the first portion of the infiltrate within the channels with the light to form a plurality of seals.
