A process for applying a barrier coating leak sealant to internally barrier coat, internally repair and internally seal leaks in piping systems, the process comprising the steps of: (a) isolating a piping system; (b) draining the piping system; (c) drying the piping system; (d) blowing through the dried piping system compressed air that is charged with particles of an abrasive substance; and (e) introducing an epoxy barrier coating leak sealant into the piping system by a continuous positive pressure of air in a single sealant stage; and (f) coating interior walls of the piping system in the single sealant stage. view more

The process as claimed in claim 1, wherein the compressed air is filtered when it exits the piping system.

The process as claimed in claim 1, wherein the introducing step (e) further includes the step of: introducing the epoxy barrier coating leak sealant into the pipe by compressed air.

The process as claimed in claim 1, wherein the piping system is a water pipe system.

The process as claimed in claim 1, wherein the step of drying (c) includes the steps of: introducing substantially moisture free and substantially oil free heated compressed air into one end of the piping system to remove all water from the piping system. view more

The process of claim 1, wherein step e further includes the step of: a maintaining the continuous positive pressure of air in the single sealant stage at a pressure level of at least approximately 1.5 P.S.I.

A process for preparing insides of piping systems for cleaning, coating and sealing and repair, the process comprising the steps of: (a) isolating a piping system; (b) draining the piping system; (c) drying the piping system; (d) cleaning the inside of the piping system; and (e) sealing the inside of the piping system in a single sealant stage with a leak sealant, and maintaining a positive pressure in the piping system during the single sealant stage. view more

The process of claim 11, wherein the drying step includes the step of: Introducing substantially moisture free and substantially oil free heated compressed air into one end of the piping system to remove the water from the piping system.

The process of claim 11, wherein the step e further includes the step of: maintaining the positive pressure during the single sealant stage at a pressure level of at least approximately 1.5 P.S.I.
