Cutting a paving slab

It's the thickness that matters...

But yes. If it's a bit too thick or you get bored, after it scoring as deeply as you can be bothered, and supporting it under the the cut- line, a good whack on the offcut ought to crack the rest away neatly enough - apart from the top edge, the rest is all presumably going to be hidden anyway.

I did it with a couple of bog standard stone cutting discs (I didn't fancy buggering up my diamond tile blade). IIRC I got about two thirds of the way through and snapped the slab over a length of wood. Easy if the offcuts are a reasonable size.

Actually, the edge is going to be visible - it's being used as a cap stone. I thought of molding one, but that doesn't look doable in 24 hours (unless I molded it in place, maybe).

You can do it, either cut'n'snap, or cut from both sides if you want a nice edge all the way... (

you will see exposed / cut aggregate either way!)

Cut both sides then as John Rumm suggested. Running along a strip of timber helps keeps everything tidy.

Yes. Deepest narrow score you can manage, then go along it with a wide bolster chisel.

I'd do one, then the other.

Personally i'd borrow or hire a bigger cutter with a diamond disc

For one slab? Blimey, you must be made of money.

Will it look odd with two edges cut, however neatly, and showing sliced-through aggregate particles, and two edges as-moulded?

If all four edges are visible, I think I'd want to run a Stihl-saw down all four.

IMO the key to this is ear protection, as well as a dust mask. It takes a while.

R.

yes ... but will take more than one disc unless you have a carbide tipped blade.
