TREMproof 250GC is a one-part, moisture-curing elastomer available in three viscosities: self-leveling, roller and trowel (trowel-grade intended for detailing work only).

Basic Uses

  • Designed for use on backfilled walls, split slab applications, planters and submerged conditions.
  • Can be used on concrete in as few as 24 hours after removal of forms, dramatically expediting construction schedules.
  • Can be applied in a single lift up to 120 mils.
  • Can be catalyzed with water to further compress construction schedules if desired especially in cold temperatures and low relative humidity conditions

Features & Benefits

  • TREMproof 250GC can be applied in as little as 24 hours following the removal of concrete forms. It can also be applied to damp concrete, reducing the delays associated with rain or other sources of moisture.
  • The unique ability to catalyze TREMproof 250GC-SL with water when desired will speed cure times, especially in cold temperatures and low relative humidity, to further condense the construction schedule.
  • TREMproof 250GC can be applied at a rate of up to 120 mils in a single lift to speed application without sacrificing performance.
  • It can also be applied in multiple lifts to achieve a 215-mil high-build system when maximum protection is required.

Coverage Rates

  • Approximately 25 ft²/gal (0.61 M2/L) at 60 wet mils
  • Approximately 18 ft²/gal (0.44 M2/L) at 90 wet mils
  • Approximately 13 ft²/gal (0.32 M2/L) at 120 wet mils
  • Approximately 7.5 ft²/gal (0.19 M2/L) at 215 wet mils

Applicable Standards

  • TREMproof 250GC meets or exceeds the following specifications:
  • ASTM C836 Standard Specifications for High Solids Content, Cold LiquidApplied Elastomeric Waterproofing Membrane for Use with Separate Wearing Course
  • City of Los Angeles (COLA) approval standards
  • Miami-Dade County Acceptance

Limitations

  • Do not apply to contaminated surfaces.
  • Not to be used as an exposed or wearing surface.
  • Use with adequate ventilation.
  • Concrete forms must be removed a minimum of 24 hours before TREMproof 250GC can be applied.
  • Not approved for direct contact with asphalt-based products.
  • Not for use with potable water.
  • Contact your local Tremco Sales Representative or Tremco Technical Service for compatibility information and job-specific recommendations on tie-in and termination details.
  • Do not apply over a curing or forming oil compound.
  • Do not apply over a non-vented metal pan decking substrate without contacting your local Tremco Sales Representative.
  • Backfilled applications require the use of a compatible Tremco protection course.
  • Applied product should not be left uncovered to UV exposure longer than 120 days or covered with a protection course longer than 120 days.
  • Where asphaltic membranes, self-adhering flashing or self-adhering sheet membranes, come in contact with TREMproof 250GC, Tremco Epoxy Primer is to be used at the overlap condition.
