GeoLinerTM Geopolymer Mortar

GeoLinerTM geopolymer mortar is a fiber reinforced product designed to provide excellent corrosion resistance along with higher strengths and lower permeability than typical cementitious linings.


ADVANTAGES
  • Great adhesion and cohesion
  • Utilizes natural and recycled materials
  • Very low carbon footprint
  • Provides high level of corrosion resistance
  • Restores structural integrity
  • Excellent Bond to damp surfaces
  • Apply up to 2” on vertical surfaces in one coat
  • Spincast, Spray Gun or trowel application

APPLICATION
Using low pressure spray equipment or trowel, apply mixed product on vertical, horizontal and overhead surfaces to a minimum thickness of 1/2” and up to 2”. Trowel or brush to a smooth finish as soon as possible, but within two hours. If additional material is required, apply up to 2” of product within 6-8 hours, then trowel or brush to a smooth finish as soon as possible, but within two hours. Ambient temperature should be minimum 40°F and remain above 32°F for 12 hours after application. Do not apply to frozen surfaces.


COVERAGE
Approximately 10 sq.ft. per 50 lb. bag at 1/2 inch thick.
