The glue must be PUR. Do not attempt to apply other glues. Our experiences has taught us that they never work properly. We recommend the following references: Kleiberit ref. 709.3, Henkel ref. QR4663 or Jowat 609.20. Any other hot PUR glue should work well. The glue should reach a temperature of up to 140ºC in order to be sufficiently liquid. The roller by means of which the glue is applied should be at a temperature of about 125ºC.
