All internal corners are caulked to give radiussed edges. Mesh laid in halfway thru the pour. Yes. Going skip wombling today on the way back from the gym - for waste melamine surfaces ...

Adrian Walker Posted November 14, 2019 Share Posted November 14, 2019 IMHO the only reason that you would want a concrete work top is that you can't afford any solid surface material, eg. corian granite, etc. Link to comment Share on other sites More sharing options...

SteamyTea Posted November 14, 2019 Share Posted November 14, 2019 (edited) I work in kitchens a lot, people spend way too much time and money on them. Stainless steel is the professionals' material of choice. Edited November 14, 2019 by SteamyTea 1 Link to comment Share on other sites More sharing options...
Bitpipe Posted November 14, 2019 Share Posted November 14, 2019 We visited a build that had a polished concrete floor - really susceptible to oily stains - i guess regular sealing helps prevent this. Link to comment Share on other sites More sharing options...

Mr Punter Posted November 14, 2019 Share Posted November 14, 2019 I just took delivery of a stone resin shower tray. I wonder if you could use a similar material and technique for a worktop? Link to comment Share on other sites More sharing options...

I wonder if you could use a similar material and technique for a worktop? What Corian, and similar, are. For a few thousand I could cast you a phenolic one. That would be sturdy, long lasting and fire resistant. It would drop sulphuric acid for a few weeks, but that will eventually stop. Not saying it would be beautiful mind.

Conor Posted November 14, 2019 Share Posted November 14, 2019 (edited) Read an article about self compacting/consolidating concrete (for my raft foundation) and it had a section on worktops. Said it was ideally suited due to it fully filling a form easily and not leaving bug holes. Also claimed that if smooth enough form was used, no polishing was needed. https://www.concretenetwork.com/self-consolidating-concrete/ Obviously you'd have to come up with your own mix... Which might be a challenge! Edited November 14, 2019 by Conor Link to comment Share on other sites More sharing options...

I'll try and find it in my history. sounds like an old worktop as a former then . and some sort of vibrating device I have made balustrade posts using plastic ornamental plant pots , 2 to a finished post--as a mould -- needed vibrating to get perfect no air bubble finish Link to comment Share on other sites More sharing options...

No compaction or vibration required. Watch some of the videos, looks like lumpy water lol Link to comment Share on other sites More sharing options...

Construction Channel Posted November 16, 2019 Share Posted November 16, 2019 Just waiting for the silicone to go off..... The big pour will commence shortly. The base ply has been sbr'd as I want it to stick to the mortar. The outside formwork had been silicone release sprayed because I want it to release..... Wish me luck ?? 3 Link to comment Share on other sites More sharing options...

Onoff Posted November 16, 2019 Share Posted November 16, 2019 I think one main reason for doing them upside down is so you can do a silicone filet around the base and end up with a well consolidated, rounded front edge. Link to comment Share on other sites More sharing options...

That was until I realised Nottingham is a lot further away from you than I thought and I was only meant to be collecting a dishwasher in the work van. I'll take the coward comment, Faye's not as available to lift things anymore and I really haven't got time to do "prototypes" at the moment.
