Outdoor porcelain slabs

Hi guys,

I wonder if someone can help please. Just finished some porcelain slabbing. Everything was perfect until I dropped my spade on a slab and it took a slight chunk out the corner of one. I managed to find the piece.

I was thinking could I use a little sbr and cement to stick this piece back on. It is going to be hidden by the bbq fortunately. So didn’t really want to faff about getting the slab back up and replacing as it’s in the middle of a row.

Or would a superglue be better?

any advice would be much appreciated.

Grab adhesive -no more nails etc. must be for outdoor use

I would use a resin based adhesive: Araldite.
