install, Attach Flannery Wall Covering Trims over gypsum board (drywall) through the taping flange and into the framing with nails, screws or other approved fastening methods. All trims must be cut accurately and installed with tight neat joints. Drywall mud and tape is then applied to the mud flanges on the trims and then feathered, tapered and sanded for a smooth transition. FRP panel or wall covering material is then inserted into the trim and fastened to the gypsum board. Flannery recommends that a carbide tip blade along with blade lubricant be used when cutting aluminum trims
