I'd like a polished concrete floor. Is there any reason why I shouldn't hire in the appropriate polishing machines and do it myself? (Or get my builder to do it.) I've looked at the specialist companies' websites and it doesn't seem difficult, just time consuming. Has anyone tried doing it themselves? Any pitfalls/tips?

Never done it but I imagine you have to start with the right sort of concrete.

My take is you only get one chance to get it right.

So personally I would at least want a helper with me who has done it before.

I think the critical thing is knowing at what point in the curing process to get busy with the machine.

Just by chance I found some light fittings that might go well with a polished concrete floor...

There's not much info on Google, but what there is looks fairly straightforward. As my builder says, they've been putting in concrete floors into garages, workshops and car showrooms for years, what's the difference if for domestic houses? I don't want a fancy surface, just a plain polish.

The lights look good - v heavy tho I'd have thought. Thanks for the link to the site, looks a good place for DIY info - tho nothing on polished concrete floors (yet!).

I am planning to simply power float the whole slab (it does need slightly higher cement proportions (rather than slag) when ordering your concrete). If power floating entire slab fails and doesn't look good enough as a finish, then we are going to hire a polisher and have a go in a utility or storeroom where a mess wont be seen. My understanding is that you can grind away once the slab is dry, its the power floating that takes timing. My understanding is that ideally for a professional terrazzo style finish you need hardener in the concrete plus colour/ special aggregate etc, but like yourselves we are going for a roughly smart look and expect a simple polish will be good enough. A sealant will be needed and topped up every few years. I am banking on protecting the surface while build ongoing with hardboard but if needs be will grind again after build if it does get damaged. The advantage of grinding the slab prior to frame going up is that there are no edges to work around. I have had a word with tool hire companies and it only costs £100 over a weekend.

I'm really keen on polished concrete, as a concept, but I've never seen it in the flesh. I presume it's not the sort of thing that companies can send out samples of, like other flooring? Any suggestions for how I could see this material in use, preferably up close and personal?

Blimey, every time you think she's finished, she has another go. Good result though. We might consider it, but I would need to see it for real to be sure. I wonder how slippery it is.

crofter - I've just googled and found a company near me that does concrete polishing. I'll probably contact them to see if I can visit a site that they've worked on

We are also looking at polished concrete for our ground floor - I understand that in addition to getting the desired finish, the other necessary task is to cut control joints http://www.concreten...ntroljoints.htm into the slab so that if it cracks, it does so in a controlled manner, otherwise you risk unsightly cracks appearing across the floor.

I have never polished my concrete floor, however i do regularly clean it.
I also degreased my concrete floor with the degreasing thinner and i think that this made my concrete floor look great!

Let me know if this helped :)

Hi, me and my husband are looking to do a polished concrete floor DIY in our new kitchen extension. I found this blog and wondered how you went with yours? Did you do it yourselves in the end? I'd be really keen to get any tips from you. Thanks Bethan and Dean from Cardiff
