Hi, I am having a go at putting in my own concrete slab for a music room in the garden - don't laugh..With a bit of help from a friend with big muscles and a mixer..
We have just finished two outer strips - but how long do I have to leave the formers in place before removing them and putting the central section in?
Please say a couple of hours is enough - as I would like to get it done today - whilst I have the aforementioned friend and mixer captive. I fear, after this morning, if I let him go, he won't come back..
And yes, it had to be in the garden. If you heard me play, you would know why..
