Prepare surfaces by removing all loose scale, rust or other foreign matter by grit blasting or
wire brush. Surface must be clean, dry and free of grease. Peel back interleaving and apply
adhesive side of the tape to the surface and press down. Apply the tape spirally with enough
tension to make it conform. Remove interleaving as wrapping proceeds. Overlap each turn
by at least 1" or 55% to achieve double thickness.
Irregular surfaces such as valves, ﬂ anges, etc. may require the use of Densyl Mastic
or Denso Proﬁ ling Mastic. Refer to the product sheets for these speciﬁ c products for
information on application and selection.
