Q: What’s the impact for the PU foam with a big bubble or uneven cell?
A: Small bubble or smooth cell is a common performance for good quality PU foam. Big bubble foam will cause thermal and sound insulation ability reduce and it may even be water leakage.
Q: How to clean the spray foam gun?A: Please use GNS Foam cleaner to remove the fresh foam.
