This product is a roll of drywall joint tape, approximately 132 ft. in length and 2 in. in width, made primarily of PVC with adhesive tape. It can be cut to the appropriate length and width according to actual needs, making it versatile for various applications. The tape exhibits ideal adhesion, high tensile strength, and high adhesion due to its PVC composition, providing better stability and structural rigidity for maintenance work. To use, first clean the working surface by removing convex areas and filling concave ones. Then, cut the drywall repair tape to a suitable length and apply it directly to the gap. Smooth it with putty and let it dry naturally before polishing it flat. Apply another layer of putty and, finally, brush paint or coating directly onto it. The tape features a foldable design with a white line in the middle, allowing it to be folded into any corner, making it suitable for filling and bonding cracks at both external and internal corners. The small hole design enhances the bonding between the putty and the wall, preventing it from falling off. This corner tape tool is ideal for crack filling on ceilings, gypsum board walls, and wooden board walls, as well as for mending internal and external corners, coating and repairing easily cracked parts of indoor and outdoor decorations, and repairing cracks and holes in corners or roofs of drywall.
