2. After the cleaning liquid is dried, stick the adhesive tape on the adhered surface, and apply a pressure of about 15PSI( 1.05 kg/cm2) by roller or other means to make it adhere effectively.
3. Tear off the adhesive tape release paper, then paste the material to be pasted, and apply the same pressure of 15PSI to make it fit effectively. If bubbles need to be removed, the pressure should be increased to the upper tolerance limit of the product.
