Molded Corners and Base Adapters are great for finishing tricky corners. Molded Corners finish corners where multiple beads meet and Base Adapters transition beads to a square corner. In this tip, we will discuss using both Bullnose Molded Corners and Base Adapters.
installing bullnose molded corners
The first step when installing Bullnose Molded Corners is to establish the correct drywall setback, as outlined in the installation instructions.
Installation is as simple as applying 847 Spray Adhesive on the inside of the 2 Way or 3 Way Molded Corner and pressing the Molded Corner on the corner to adhere. Secure the Molded Corner into place with 1/2" staples.
To create a clean transition, it is important to eliminate any gap between the Molded Corner and Bullnose Bead. To do this, place a dab of drywall stud adhesive on the tab of the Bullnose Molded Corner and install the Bullnose Bead over the tab of the Molded Corner.
Complete the Molded Corner installation by cleaning off any excess drywall stud adhesive.
installing base adapter with crown molding
Base Adapters are designed to transition beads to a square corner. When using Base Adapters to install Trim-Tex Crown Molding, the vinyl crown molding must be installed first. Once the crown molding is installed, trim back the mud legs on the crown molding to best accommodate the Base Adapter.
