Prepping for Epoxy w/o Water

[Metallitubby]

The shell of my new shop/barn build is up and I'd like to start painting the floor. The issue is that I do not have water run to the shop yet. Any ideas are appreciated regarding cleaning and prepping the concrete.

Use a large vacuum.. 250CFM+. The same type of vacuum that would be rented with a floor grinder. Be sure to vacuum the floor really well in a cross-hatched pattern after you are done grinding. Solvent wipe with rags and acetone or denatured alcohol.

Awesome. Thank you for the quick response.

My initial plan was to use a broom > leaf blower > broom, but then I was lost after that.

You are welcome! The problem with that method is you will be putting a lot of concrete dust into the air that you will breathe in. Concrete dust is very bad breathing. Be sure to wear a half face respirator while grinding.

Hi,
vacuuming alone would not be a sufficient prep for a proper coating. Best to rent a diamond floor grinder with proper matching vacuum and do it properly.

Good prep=excellent results. We would never warranty a project that was not either etched or grinded for prep, and I think most other vendors on GJ would agree.

How old is the slab?

Under no circumstance would I apply any coating without at least a chemical etch. My issue is trying to get the chemical off without water at my build site.

How old is the slab?

28 days today.

No advise, just over here admiring that space!

Can you carry water for a pressure washer? 20 minutes worth = 60 gallons. Three trips?
A proper grinder with vac will work.

Thank you. it's a bit of a blank canvas at the moment.

I think with what you guys are suggesting, and from the logistical standpoint, that I am going to just wait until the house has water run to it and go from there. Another question to those in the know:

When during a garage build would YOU paint the floor?

1. Before studs/drywall and electrical but before the lift install?

Are you going to apply “paint” to the floor.

Common parlance.

I am still undecided which style of epoxy or poly I am going to go with.
