Title: Casting concrete worktops
Post by: Julian on October 29, 2014, 08:42:39 PM
I use a sheet sander held against the side when vibrating smaller cast concrete work tops, also have a small Makita vibrating poker if you want to borrow it

Interested in the concrete worktops.  Done some googling on them in the past and nearly tried making them at home but  thought better of it.

Of most interest is the polishing and sealing.

Looks pretty good, I'm impressed.

I really fancy having a go, but no requirement or outlet for any worktops at the moment.  Did you seal them with anything, all same travertine or marble?

That grinder ... it looks like the water is fed to the center of the spindle, is that the case?

Yes same sealer as used on granite work tops etc and yes the polisher is water fed down the centre of the spindle, no different to a grinder except for speed control really

Cool!

Looks like you cast it up side down rather than in situ?  Any reinforcement?

Yes rebar and added some fibres to the mix

I'm guessing you cash the holes inside it, not cut them out later ?

I fancy making one for work when I sort out the new toilets, probably 8 foot long, with 2 sinks in it


I'm guessing they're crazy hard wearing and wouldn't be bothered if they get steam cleaned every day ?
(probably just lightly / at a distance)

Yep, everything done in the mould, cast upside down, concave quadrant in the corners to give round edges, half round to make the drain grooves etc
Very hard wearing but they will stain unless sealed

More interest in your worktops than bio ... I vote for a demo at BBB 2015.

It would, at this point, be fitting to add a comment about walking on water ... but I'll refrain.

Posting those is just a cop out.  We want a demo ... do we have to have a poll on the subject?

Im buggered if im lugging a concrete mixer to Chugs!  :)

Chug's probably got one he'll lend you!

Anyway, most people know how to mix concrete, it's the polishing bit we want to see.  You, or indeed others, could do the mixing and casting bit before hand and bring the cured slabs to the BBB.

Pretty cool. Polished concrete is pretty big in SE Asia. Cheap, and hard wearing, I guess.
Some poor blighter gets to sit all night, working it up to a shine, as it goes off. I think they use water and sand, and then work it up with a sponge. In the morning, you can see your face in it.

I'm just wondering how much more weight I can get in  my caravan, before the whole lot disappears through the floor.....

I was chatting to a design student on Thu, making a Shepherds hut, mainly from a kit, he was going to stick a lead roof on it! :o

Shouldn't that read "shall we have a poll on the job"?

We've all heard about those dodgy builders on the tele, very expensive and very unreliable prooly won't turn up even if you booked him now.

As for walking on water I'll have to get some practice in,  ain't done it for a while.
