Buying Guide: Choosing Sika Sealants and Adhesives

Sealants for Joints and Cracks
Some caulk sealants and self-leveling sealants suit horizontal concrete cracks, expansion joints, sidewalks, garages and patios. Self-leveling versions flow into cracks, while non-sag construction sealants suit vertical and overhead joints around windows, doors and brickwork. Choose a color that matches the surface you are sealing.

Adhesives and Backer Rod
Construction adhesive bonds materials such as concrete, brick, ceramics, glass, metal and wood, and is waterproof after cure. Backer rod partially fills deep joints before sealant goes in, which helps prevent three-sided adhesion and lets you control sealant depth.

Before You Buy
Measure the joint width and depth before ordering, and check that the sealant suits the surface material. Follow the manufacturer's instructions for surface preparation and curing time.
