Should I radius slab edges?

Hi

I've done footings and bedding/haunching before but am going to cast my first surface exposed slab.

Looking at YouTube videos they are all USA and seem to use a corner trowel to round off the edges:

Is that normal UK practice too? Or is there a normal way here of easing the edges to provide frost and damage resistance?

Thanks

Deffo bull nose it, or the edge will get knackered. Same as for a floor slab under a garage door

You need to wait until the muck has hardened a wee bit. There's nowt wrong with getting the initial shape, whilst the conc' is pliable. But to get a good wearing tight finish, you need to work the trowel, when the gear has stiffened quite a lot. We've laid in the morning and still been faffing about at 6:00 p.m.

Oh well, if you're going to lie around in bed getting up to no good you can't complain at having to knock off 4 hours late!

Reminded me when I was a kid and dad would let me cut the grass with the Atco cylinder mower and I would end up shaving the edge of the slabs with it - eventually they were rounded off enough so the mower didn't catch any more

Kept the blades sharp too!
