Polished Concrete

[learner]

Hi Experts

Im looking to do a polished concrete floor in my small bathroom, 10m2 max, perhaps with some blue glass aggregate.

Anyone got any advise??

Thickness?

What to lay it on, raw floor or onto self level compound??

Hand Grinder or large machine?

Correct mix?

May seem silly question but im up for the challenge

Thickness of concrete  will determine whether i can do this....

You could always lay microcement instead. That’s only 3.5mm thick.

Polished concrete is just that … you polish (grind) off the top of the concrete slab to reveal the aggregate. As you already have the slab you are just wanting a decorative layer.

loads of aggregates available to mix with self levelling compounds etc which can then be ground back to reveal the agg. You need a decent size floor grinder to minimise scalloping and ending up with waves and ripples in the finish

You need 75mm for polished concrete. If you have this then let me know and I'll provide a lot more information to help you. For example you have to use a special type of glass aggregate. Regular glass will shatter during the grinding process.
