The Taper’s Essential
- Ideal for bedding joint tape, smoothing out first and second coats, and general patching.
- The stainless steel blade is highly recommended for use with "hot mud" (chemical-set compounds).
- Use the corner of the blade to clean out excess mud from inside corners before it sets.
- To maintain the edge, keep the protective plastic guard on the blade when stored in your tool bag.
