As Described In AIPPR IGC-351-18

With our Quik Coating process that launched in December of this past year, we’ve armed many new and existing customers with a tool in their toolbox to rehabilitate drain, waste and vent pipe. Many have embraced the technology and have grown their businesses with the process adding multiple units to their tool chest to meet customer demand. As there was very little history with the process we’ve learned what you can and can’t do, tricks of the trade and other valuable lessons regarding the process.

We learned that you can coat larger piping that we originally thought possible. We’ve successfully coated 14” diameter pipe with the process saving a rotted HVAC duct that moisture attacked and was winning. Using some larger diameter hoses and 16” brushes the pipe was coated to prevent further corrosion.

Flexible CCTV cord works best with the pull back as no one is needed to “respool” the push rod back into a reel. Our small 13mm camera coupled to a foot pedal operated high speed cable machine makes the operation perfect for a single operator. The single operator can clean and coat without the need for a second hand to complete the work.

We found out that there is a minimum and maximum thickness you can apply to pipe. If double the amount we specified for a particular pipe won’t stop leaks, then other methods should be employed to solve the problem. Point repairs may cover gaps, especially in the top of horizontal pipes, better than trying to keep applying more layers of resin. A 3/8” gap in the top of the pipe may be sealed with our poly urea resin, but larger gaps at the top need a different approach. We’ve seen customers fill a 2” gap in the bottom of the pipe however with ease. We’ve set a minimum thickness for different sized pipe. Too little may not resolve your problem as depicted in the photo below. A .5mm thick coat wasn’t enough to cover badly cleaned pipe and the pipe coating sloughed off.

Cleaning pipe is the most critical operation. If you leave bumpy scale on the pipe, you run the risk of leaving a piece of scale uncoated and eventually that area will delaminate, especially if you’ve apply coating too thin. A breach in the coverage will allow corrosion to continue to build behind the coating and push it off the wall as it grows.

Too little coating thickness applied to poorly cleaned pipe

Another thing we’ve learned is that keeping your tubing and pumps free of crystallized resin will insure that your resin will remain a constant 1:1 mix. Moisture and cold temperatures add to the crystallization problem. We also learned that if you allow the pumps or tubing to get filled with crystallized resin and the mix isn’t 1:1, your coating will remain sticky and not curing in the 5 minute time frame telling you that you need to check your flow. We also found that heating the tubing to at least 140F, the crystallization will melt back to liquid. If crystallization has invaded the containers, you can skim any crystallized resin off and continue using the material. Melted crystals from the A side when mixed with the B side will still produce the same structural value as resin not displaying any crystals.
