Epoxy Floor Questions

[pokop]

I am starting the prep work on the floor of my garage. I filled in the hairline cracks and am now beginning to grind the entire 750sqft with a 4in grinder... going to take a while but trying to save money and would rather spend my time. It goes decently quick but will for sure take hours to complete. Also to note epoxy flake flooring st louis, I live pretty rural and the home improvement stores near me do not carry grinders or rental tools for that matter.

I am currently grinding, then onto a degrease, primer, base/flake, and clear.

1. How long do I wait between primer and base, then base and clear?

2. I leave for vacation soon and was hoping to have primer down before I leave. Is this fine to sit for 10 days or do I want to apply base shortly after applying primer for better bonding?

3. Have any of you used GarageFlooringLLC before? I plan on using their High Solids (93%) Epoxy for a blend between better durability and cost compared to the DIY kits from Lowes and Home Depot or a professional epoxy. All in about $1100 (Primer, Base, Flake, Clear Top Coat)

Any other tips and tricks would be helpful. Cant wait to see the final result!
