Greetings,
Don't laugh, but you may be able to screw down the gypcrete to keep it from moving with large backerboard screws. This will be a lot quicker.
Hope this helps, William

I'm looking for informed comment and/or advice on a plan to repair cracks in my 1-1/2" thick gypsum-based (gypcrete) floor.
Problem: The floor is broken up into fairly large sections that are separated by hairline cracks. When I walk on a section, it moves just a tiny bit, causing its edges to rub against adjacent sections. This results in annoying crunching and crackling sounds.
Objective: I want to eliminate the crunching/crackling sounds without the big expense and hassle of pouring a new gypcrete floor.
Assumption: A series of cement "plugs" along the crackline would provide the rigidity needed to prevent the sections from moving and rubbing against each other when stepped on.
Plan:
Considerations: Since the gypcrete is meant to prevent a fire from burning through the floor into the wood structure below, the "plug" material must be fireproof and have roughly the same heat-transference properties as gypcrete. Cement is used instead of gypcrete as a repair material because it's considerably more resistant to shear stresses than gypcrete.
Thanks in advance for all helpful replies.
