Customers have been impressed when removing a small patch of Trenton Wax-Tape for inspection purposes. They consistently find the surface in the same condition as when the tape was first applied. After inspection, the small patch can then be reapplied for continued protection.

It remains pliable and supports cathodic protection. Trenton’s Wax-Tape® #1 wrap is a widely used product in a variety of settings in the oil and gas, water and chemical industries.


Wax-Tape #1 wrap is composed of a blend of microcrystalline waxes, plasticizers and corrosion inhibitors saturated into a non-woven, non-stitch bonded synthetic fabric, forming a tape wrapper. They also contain no siliceous mineral fillers.

End Use

For application on belowground metal surfaces, pipe or fittings to prevent corrosion.

Application Procedures

Wire brush and scrape the surface clean of dirt, loose coating and loose rust. Apply a thin film of Wax-Tape® Primer. If the surface is wet, cold or rusty, rub and press on primer to displace moisture and ensure adhesion. Then wrap Wax-Tape #1 wrap using a 1″ overlap. On straight pipe apply slight tension to ensure contact with surface. On irregular surfaces allow slack so the wrap can be molded into conformity. In either case, press and form the wrap so there are no air pockets or voids under the wrap. Also, press and smooth out the lap seams to ensure they are sealed. The wrap does not require curing or drying time so it can be backfilled immediately. For belowground pipes that are 10” or larger, apply a Trenton outerwrap. For aggressive soil conditions a Trenton outerwrap, a rock shield or select backfill should be considered.
