Floor treatment first or foam insulation first?

[*JJ*]

Hi! I'm new to the forum but have been creeping around on here admiring your garages and ideas for a while. My name is JJ and I live in Texas.

I'm in the process of getting a build ready for a detached 20x30 garage. I'm planning to have the floors treated with polyaspartic and the walls with foam insulation. So which is better to install first? Floor first, then insulation...or insulation, then floor. The insulation installer said he would overlap the insulation onto the floor to seal the base of the building, but I just don't have enough knowledge to know whether I should wait on the floor or do it first.

I tried to search the forum, but didn't get what I wanted. Thanks for helping out a newbie.

Normally it's floor last. However, in this case maybe let the insulation man finish the job.

many foam installers are quite sloppy and do not worry about over spray or what is left for you, to clean up...

foam is tough to remove from concrete, not sure about epoxy - it should be easier, but I have no experience with it.

Either way, I would make it a contract item that they mask and cover and that NO foam gets on my floor or elsewhere, or THEY clean it up

I have a 30x40x12 Mueller building with foam insy and epoxy floors.
My foam installers covered up everything not getting foamed, including the floor.
The 4-wheel man-lift they used did mark up the floor a little through the plastic, but it was an easy clean-up, followed by epoxy coating.
They did not overlap onto the floor , nor would I have allowed it.

Thank all of you for your responses.
