Self-adhesive plastic corner tape has PVC (polyvinyl chloride) backing coated with glue. There is a line in the middle of the tape that can be folded into any corner, and the small hole design makes the putty better bond with the wall.

Self-adhesive corner tape is used for repairing internal and external corners of walls and ceilings, covering and repairing cracked parts of indoor and outdoor decorations. This tape is also used on corners for a neat, clean and finished look. It is twice as strong as traditional paper joint tape: resistant to tearing, shrinking and wrinkles. Easier to install than metal corners, easily cut with a scissor or a knife. Prevents cracks and dents.

How to use
Firstly, clean the working surface and smooth it. Then cut the self-adhesive corner tape to a suitable length and directly apply it on the surface, smooth it with putty and after drying, polish it flat, then brush a layer of putty.
