- Uses
XtraBond®250 can be used for a variety of applications including, but not limited to, walk-in coolers & freezers, cultured marble, kitchen & bath, industrial, marine, etc.
- Direction for Use
For best results, prepare a clean surface. Cut nozzle to desired bead size. Apply with caulking gun, forcing sealant onto the substrate, then tool if needed. Clean excess material with mineral spirits or similar solvent.
- Surface Preparation
The substrate must be clean, dry, frost free, sound and free of any oils, greases or incompatible sealers, paints or coatings that may interfere with adhesion. Do not apply if surface is damp or contaminated. It is recommended to test all substrates prior to applications. Primers are not required for most substrates.
