Vidicom CEO Christy Ferer suggests choosing a trim that fits into the molding groove you have chosen to fill. Apply glue 1 foot at a time. Hold trim down for about 30 seconds. Time is of the essence because the glue works very quickly. As you glue on the trim, be careful not to allow the weight of the slack to tug down the trim you have just finished gluing. Corners can be cut at 90 degrees or 45 degree angles, or you can just turn the corners with the trim.
