Buying Guide

Match adhesive type to substrate

Choose a product formulated for your materials—wood-to-metal, concrete, masonry or general-purpose clear formulas perform differently

Consider cure time and moisture activation

Faster tack or moisture-activated polyurethane works better outdoors and for damp joins, while slower cures allow repositioning

Check container size and application format

Bottles, tubes, and semi-self leveling cartridges affect waste, precision, and suitability for small repairs versus large pours

Look for water and weather resistance

Select waterproof or water-resistant formulations for exterior use, bathroom repairs, or surfaces exposed to moisture

Evaluate bead behavior for the job

Semi-self-leveling sealants smooth for horizontal joints, while thicker glues are better for vertical or gap-filling bonds
