Elevation® SM2 Lap Sealant

Elevation® SM2 Urethane Waterproofing is a multi-purpose, resilient joint sealant that combines economy and high performance. It is ideal for a wide range of applications where joint movement requires compression and extension in excess of 25%. SM2 is a moisture-curing polyether sealant that is effective in damp, dry or cold climates. It is free of solvents and isocyanates.


Elevation® SM2 Urethane Waterproofing is a multi-purpose joint sealant that will not shrink upon curing, bubble on damp surfaces like polyurethanes sealants often do, or discolor when exposed to UV light.

Elevation® SM2 Urethane Waterproofing has excellent elastomeric properties and adheres to most construction materials including difficult surfaces such as Kynar 500® PVDF and other anodized metals and coatings. SM2 can be applied to damp surfaces at temperatures as low as 32°F (0°C), making this Lap Sealant effective in many difficult construction site conditions.
