when you pull the facer up on the sides, how much of it gets to stay on the sides ? If most of it comes back down and level up by itself then what is left on the side is always too thin to stay hydrated while waiting for the backer, how do you force 3mm+ facer stay vertical? and there is also the sliding off marks

Its all in the mix! And there are sometimes some marks on the vertical faces but that is an artifact of the process and never looks unsightly.

Yes provided the concrete is 40mm thick or more

Hi - Just looking at purchasing some material to create a worktop for an outdoor kitchen area. Following your guides you suggest a thickness of 18mm. Can you pour multiple layers to make the worktop thicker [circa 40mm] or would you not recommend it?

Hi Sam. With our Cast-In-Place Mix we recommend between 25-40mm thickness.

@@ConcreteLab Ah! I was looking at casting into a mould, would you suggest casting in place then?

Hi Sam. That’s up to you really. The Cast-In-Place Mix method gives a more traditional rustic finish because you would be trowelling the top surface. The GFRC Premix is a more polished modern finish because you’re casting the concrete against a smooth surface. If you go to our website and take a look at our Guide on How To Make A Concrete Worktop, we show you how you can achieve the 40mm edge thickness without casting the entire piece to that thickness.

@@ConcreteLab Thanks. If I went for the GFRC at 2000x930mm, would 18mm thick [including a 40mm downstand/lip] supported on a timber frame be strong enough?
