Sealants & Caulk for Tile Installation & Waterproofing
Sealants and caulk are flexible joint sealants used in tile installations to accommodate movement and create watertight seals. Unlike rigid grout, sealant and caulk products remain flexible after curing, allowing them to absorb expansion, contraction, and minor substrate movement without cracking. This flexibility makes them essential for maintaining waterproof integrity and long-term performance.
Sealants and caulk are commonly installed at changes of plane, perimeter joints, penetrations, and transitions where tile meets other materials. This collection includes silicone sealant, polyurethane sealant, waterproof sealant, and joint sealant products formulated for compatibility with tile, stone, waterproofing membranes, and common construction substrates.
Whether using silicone caulk in wet areas or polyurethane caulk for exterior or high-movement joints, selecting the proper joint sealant helps support reliable sealing and durability.
Types of Sealants & Caulk
- Silicone Sealants: Excellent flexibility and water resistance for wet areas
- Polyurethane Sealants: Strong adhesion and durability for interior and exterior joints
- Joint Sealants: Used to fill and seal movement joints in tile assemblies
- Expanding Foam Sealants: Used to fill larger gaps prior to applying finishing sealants
Selecting the Right Sealant or Caulk
- Application Area: Wet area, interior dry area, or exterior location
- Material Compatibility: Confirm compatibility with tile, stone, and adjacent materials
- Movement Capability: Choose sealants rated for expected joint movement
- Cure Type: Fast-curing or standard-curing based on project timeline
Common Applications
Sealants and caulk are used in showers, tub surrounds, backsplashes, floors, walls, countertops, and exterior tile installations. They are also applied around plumbing penetrations, fixtures, and perimeter edges.
Flexible Sealing & Long-Term Performance
Using flexible sealants instead of grout in movement areas helps reduce cracking, improve waterproofing performance, and extend the life of tile installations. Properly selected sealants and caulk support long-term joint integrity in residential and commercial environments.
