3M Sealants for Building & Construction

The ability to expand and contract at joints is vital to a building’s structural integrity. Equally important is sealing out the elements to regulate indoor temperatures and reduce noise pollution. 3M’s polyurethane sealants offer an ideal elastomeric bond that allows those joints to move while sealing off the building interior.

Water ingress is a big concern where the interior and exterior wall meet the slab foundation and where building components (plumbing, HVAC or electrical) enter and exit. Specially formulated building sealants from 3M offer marine-grade protection to ensure watertight seals that hold up to challenging at-grade and below-grade environments.

Tightening up the building envelope is fundamental in maximizing energy efficiency. New architectural techniques are effective in optimizing air flow but can be a challenge to build and seal. Using 3M’s adhesive sealants in construction helps you build to spec with flexible, durable bonding to fill gaps and maintain ventilation efficiency.
