Buying Guide
What to consider when choosing plastic bullnose corner bead products
- Interior vs exterior use: Most bullnose products described here are intended for interior corners. Check labeling to confirm suitability for exterior use if needed.
- Corner type: Determine if you need inside corners, outside corners, or multipoint corner caps (3-way or 2-way). Cap systems can reduce mitering, while beads provide longer edge coverage.
- Profile and size: Bullnose sizes vary (e.g., 2-way, 3-way, 3/4″ edge). Choose a profile that matches your wall thickness and molding plans.
- Installation method: Some products require standard mud adhesion, while others are cap-based for quicker alignment. Consider your preferred workflow.
- Compatibility: If you already use Phillips gripSTIK or other corner bead systems, verify compatibility with the cap or bead you select.
- Quantity and length: Long strips reduce seams on large runs; multiple-pack options help cover multiple corners efficiently.
