sealing concrete like a boss

[Xist]

I am helping my new boss set up his bakery. We have been trying to seal the concrete seams. The line going vertically, if I can get this to post from my phone, is $21 minute sealer, which sealed faster than we could work, but would be okay if we had more time, just expensive. The lateral line is $7 sealer that takes an hour or two to start sealing, and that is just too much time for something to go wrong.

Do any of you have experience with this?

Use the slow set and use a sheet of timber, ply, or even coroplast (cut into strips) to protect the seams while they set. Even just using bright coloured tape around the joints will serve as a reminder not to walk on them.

He put painter's tape along each side, but a power cord ran across and pulled out the sealant.

Do you have some chairs, ladders, tables etc you can use to elevate the extension cords?

I guess that we could have suspended them from the ceiling, but hopefully he finished grinding the concrete.

I guess that he could have just been more careful. Don't you like advice like that? "Just don't get the cord in the concrete seal and you will be fine."

He talked to someone at Home Depot who recommended a tub of what seemed to be quick-setting concrete, which seemed to work well. There was a two-foot section of the cheaper and slower-setting sealer that worked perfectly, but since the rest came out easily, I spent an inordinate amount of time shredding it with a knife.

One difference may have been that we swept and cleaned out the cracks with water and a shop vacuum. Perhaps the other sealer worked properly, it just bonded to a layer of dust.

Thank you for your assistance.
