AUXILIARY POSITIONING: This self - adhesive drywall corner tape can assist you in positioning, allowing you to move on to the subsequent mudding work more quickly. It saves a significant amount of time compared to the traditional way of dealing with corners. Note that the adhesive on this self - adhesive drywall corner tape is for positioning. Once stuck, proceed with mudding the corner promptly. If left on long, the tape may fall off. CORNER STRENGTHENER: This drywall corner tape enhances the structural integrity of corners, resulting in straighter, more rigid corners with precise 90 - degree angles. Effectively protects both inside and outside drywall corners from abrasion and damage, creating clean, crisp corner lines. JOINT PROTECTOR: As a joint tape, it strengthens and reinforces joints and helps prevent cracking along the joint lines. The round hole design on the tape allows the putty to make full contact with the wall surface, making the adhesive bond even more secure. WALL CRACK FIXER: Using this product to repair cracks in wall corners is also an excellent choice. For repairing uneven textured walls like Knockdown or Orange Peel, it is recommended to sand the corner tape area to flatness before pasting, or choose corner tape with nails/glue for auxiliary fixing. Otherwise, the self-adhesive corner tape may have insufficient adhesion, lifting, or peeling, making it difficult to ensure the effect and durability. RENOVATION ESSENTIAL: It is widely used in various renovation projects, including home improvement, workshop refurbishment and old - house renovation. It can be applied to the surfaces of materials such as drywall, wood, metal, paint, plaster, plastic, or concrete, etc. Drywall Corner Tape Self-Adhesive - PVC Drywall Corner Bead, Drywall Inside Outside Corner Tape (1.96" x 131′)
