Issue with concrete surface...?

Would never entertain mixing for a slab or footings on site by hand or mixer.
Either ready mix or mixed on site by the lorry.

Nothing could be simpler. You just fit the grinding disc to a 9" grinder and use it like you would use a sander, holding it flat and using a sweeping motion across the slab. The biggest issue is going to be with airborne dust, if you don't have some form of extraction. Our grinders have a moulded silicone shroud but you could knock something up from a draught strip brush etc. You could add water to make a slurry but it still means a lot of clean up and you're going to get much higher wear on the diamonds.

We was more interested in the walk behind machines, like a buffing machine

is there any chance the cement was old stock/already off?

I've got one of those petrol walk behind floor grinder thingies... bought it to take the paint off a floor before I concrete on top of it

should be using it on the paint this week

I'm happy to lend it to anyone who needs it after that, could probably send it on a pallet each way

it's old old, but starts first full of the handel every time :-)

Did you have a go at this @knighty ?
I'm getting close to having a go.

not yet, I've been crazy busy at work :-o

I dug out an old/spare android phone to try it on but didn't get around to testing it yes, it'll probably be the weekend before I have a chance
