Four: How to use
According to different gaps, seam width, choose different specifications of tape.
Degrease and dedust the surface to be bonded to keep it dry and clean. For difficult-to-stick interfaces such as PVC, rubber, cement, and wood, an appropriate primer can be selected.
Unfold the film and lay it on the place to be patched, remove the release paper, and stick the tape to the sealing gap
Roll the surface of the tape by hand or a small pressure roller to make it fully adhered to the surface to be adhered to ensure that the tape and the surface of the object to be adhered are closely combined.
For surface finishing, remove excess with a knife.
Five: Considerations
The water, oil, and dirt on the surface to be pasted must be removed before use. The cement surface must ensure that the surface is free from sand.
This tape is pressure sensitive, the more pressure, the stronger the adhesion. When bonding, please be sure to press to make it close, and no gaps, air bubbles, etc.
