SewperCoat® Wet installation method

SewperCoat® is generally installed with the wet shotcrete method. 

It is formulated to be applied with low-pressure, wet spray equipment, typically a progressive cavity rotor-stator pump. The material is mixed with water and conveyed through a hose to a hand held nozzle. The nozzle has an atomizing tip that uses air pressure to propel the wet SewperCoat®, spraying it onto the surface at a low velocity. Being a low-pressure wet process, this installation method has very little rebound and is ideal for confined spaces, such as manholes.

  •  First the structure is located, inspected, and thoroughly cleaned.
  •  SewperCoat® is then mixed with water in a traditional mortar mixer.
  • Once the proper mix consistency is achieved, SewperCoat® is discharged into the pump hopper and pumped through the hose to the nozzle.
  • The nozzle is used to install SewperCoat® onto the surface at a minimum ˝" (1.27cm) thickness.
  •  Care is taken in severely deteriorated areas to ensure that SewperCoat® is properly placed.
  • After the structure has been completely coated, SewperCoat® is trowelled to ensure proper compaction and a uniform and even surface.
