Adhesive Sealants

High strength construction sealants for a tighter building envelope

Seal out the heat, humidity, UV rays and water ingress and seal in your reputation for buildings built to last. Specially formulated 3M construction joint sealants and flexible sealants are an easy, efficient way to boost productivity by replacing or reducing mechanical fasteners or nails on the job site.

Adhesive sealants for your application

The smallest flaws in the building envelope can turn a project into a liability. Protect your build and your business with 3M construction sealants engineered to outlast mechanical and environmental strain.

Expansion joints

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.
Moisture barriers

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.
Gap-filling bonds

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.
