Repairing concrete

[jimc]

I just had a new slab layed for a new garage. I had 32mpa layed at 100mm thick with steel reo etc etc etc. My concreters used a machine to give the surface a burnt finish.

My questions are.....

A leaf was machined into the surface and left a small pit 3 - 4 mil deep from the surface. How could I fix this?

Whats a good product that will stop oil from staining the surface and will last?
Has anyone tried mixing PVA glue with water for this?

Advice appreciated.

repair with the right sort of epoxy mixed with fine sand.

But my first reaction is why bother, it's only a garage floor for Pete's sake
If you're thinking of using it as a workshop you'll almost certainly want to put some form of cushioning down to stand on which will also hide the "leaf feature".

As to coating the floor you're local hardware should have a concrete sealing paint. Painting the floor with this will virtually eliminate the dust that comes off all concrete floors, and make cleaning-up any oil spills relatively easy. If it were me I'd be using a metal drip pan if I wanted a totally oil free floor.
