MIXING RESINS: Unfold the fiberglass mat and position the mat with the fiberglass side up and the felt side down, (shiny side is the fiberglass side). Mix the two-part 100% solids epoxy bag together. Mix until both components become a uniform color and consistency (approximately 2 minutes).
IMPREGNATING THE MAT: Pour up to 1/2 of the contents onto the fiberglass side of the mat. Using the spatula, spread the resin evenly and liberally to coat the entire surface. Flip over the entire mat to the felt side. Pour the remaining resin and spread evenly throughout the mat. When properly folded, the patch should be the specified ordered length with a 1″ overlap in the center.
LOADING THE BLADDER: Center the wetted mat on the protected bladder. Tightly roll the wetted mat around the protected bladder overlapping as you go. Secure the wetted mat to the protected bladder using zip ties provided. Position the zip ties evenly throughout the mat with two zip ties attached 1″ from the leading edge of the liner and one positioned 1″ from the end of the liner. Excess zip tie straps should be cut off and discarded. Introduce the bladder and Perma-Patch™ assembly into the host pipe to be repaired. Push or pull the packer into the pipe and position it at the point of repair as marked on the air push rod.
INFLATING THE BLADDER: Please note the bladder should be calibrated regularly to determine proper inflation pressure. Place the bladder in a pipe cut to the same length as the bladder and inflate to determine full contract pressure and add 5psi. DO NOT over inflate the bladder; this may result in injury or property damage. Bladder inflation pressure may vary due to bladder condition.
REMOVING THE BLADDER: Leave the bladder in place under normal maintained pressure allowing 3 hours cure time. Deflate the bladder and remove using the attached air push rod. Inspect the Perma-Patch™ repair with a pipeline inspection camera and video the repaired area.
