Most spray foam companies either throw out scratched chambers, or try to fix with sand paper. This is an unnecessary waste, considering new chambers are around $160 each, and reconditioning is usually only $35. Utilizing sandpaper will eventually cause a multitude of problems, such as the sides becoming unparrallel to each other, which can cause leaks and inconsistent product .
The insides of chambers also become scratched from drill bits and the massive volumes of foam that pass through the chamber. This results in an abnormal spray pattern. This is fixed by reaming the insides of the chamber.
