Buying Guide: Key Purchase Considerations

- Flexibility and adhesion: Ensure the product maintains adhesion while surfaces flex or heat up from cooking, and confirm compatibility with typical kitchen substrates.
- Cure time and durability: Fast-curing formulas reduce downtime; long-term durability matters for high-moisture environments.
- Project scope: Large projects may benefit from bigger cartridges; small fixes may be easier with 2.8 oz tubes.
- Mold and mildew resistance: Especially important in humid kitchens and backsplashes.
