Application Instructions

1.)	Remove all contaminants such as dirt, oil, scale and excessive moisture.
2.)	Brush Petrowrap® Primer A evenly over surface to displace remaining moisture and ensure proper adhesion.
3.)	Press Petrowrap® Mastic B into surface irregularities to eliminate air pockets.
4.)	Wrap Petrowrap® Tape C spirally around prepared surface using even tension. An overlap of 55% is recommended to assure total protection.
5.)	Finish with Petrowrap® Overwrap D applied like Petrowrap® Tape to prevent mechanical damage as required.


	The PetroWrap® Anti-Corrosion System
	Developed for long term protection of metal surfaces that are underground, underwater, or exposed - even in the most severe environments. It consists of a cold applied system of petrolatum-based PetroWrap® AntiCorrosion Tape, PetroWrap® Primer, and, where contouring is necessary, PetroWrap® Mastic. PetroWrap® adheres to surfaces without heating, even on damp and/or indifferently prepared areas.		PetroWrap® System PetroWrap® Primer Paste is a preparatory primer that displaces moisture, pacifies oxides, and fills small irregularities that occur on the surface to be wrapped with PetroWrap® Anti-Corrosion Tape.
			PetroWrap® Mastic is a cold applied filler which profiles areas to be tape wrapped by easing contours on pipe joints, flanges, bolts, and other irregular shapes to be wrapped with PetroWrap® Anti-Corrosion Tape.
			PetroWrap® Anti-Corrosion Tape consists of a non-woven, stitch bonded, synthetic fabric which has been fully impregnated with neutral petrolatum based compounds and inert fillers
