Install all Plaster Corner Trims using full ten-foot lengths wherever possible. Attach Plaster Corner Trims over the weather resistant barrier to the framing with nails, screws, or other approved fastening methods. All Plaster Trims must be cut accurately and installed with tight, neat joints. All nailing flanges must be covered with lath and all butt joints must be sealed. Manufacturer recommends that a carbide tip blade along with lubricant be used when cutting any aluminum trims.


Flannery can radius Plaster X-Molds when the trim runs along a “curved” or “radiused” plane. Radiused material is bent to a project’s dimensional requirements and is considered a custom product. Download the Radius Form or view all of our radius forms.
