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.
