100% Solids Underwater Curing Epoxy Mastic

PerpetuCoat M™ is an exceptional two-component, solvent-free, 100% solids, ultra high build epoxy coating that can be applied to dry, damp or wet surfaces. Its thixotropic characteristics provide sag and run resistance and allow it to be hand or spray applied to vertical and overhead surfaces. Its uniqueness is its ability to displace water while forming a tenacious bond to the substrate. Its flow characteristics result in a smooth, glossy, homogeneous film that is impervious to water and is resistant to abrasion, oils and chemical attack.

Typical Uses

New or existing structures where waterproofing is required, or areas where exposure to concentrated acids or other caustic materials may be expected, such as:

  • Manholes
  • Lift Stations
  • Clarifiers
  • Digesters
  • Tanks
  • Large Diameter Pipes
  • Chemical Troughs
  • Wastewater Facilities
  • Secondary Containment
  • Floors and Walls
  • Waterproofing for concrete, metal, and wood
