Operation:

 

PREPARATION FOR USE
Substrate must be clean, firm, free of loose particles and free of dust, grease and mold release agents.
Surfaces not to be foamed must be protected. Shake cans well before using.

 

Application method
1. Shake can well to make the foam ready for use
2. Clean the substrate and spray some water on it
3. Screw foam dispenser on tightly and turn can upside down
4. Vertical fills the gaps from the bottom upwards
5. Foam is tack-free (dry to the touch) in 8 minutes in temperatures between +18℃ and +25℃ (65℉ ~77℉). Higher temperatures will result in faster curing times
6. Remove fresh foam over spray with Sepuna Foam Cleaner or solvents such as acetone. Cured foam can only be removed mechanically.


Remark: For gun/professional foam, an additional foam gun dispenser is needed to spray (Needs to buy separately). In such case, you may also need to buy foam cleaner to clean the gun adapter after use.
