I would like to lay some garden slabs, which are decorated with plastic bottle tops to add colour.
Initially I was thinking of making my own slabs with concrete and decorating before they set, however, a friend suggested buying pre-made slabs and then putting some sort of top coat on them to set the bottle tops.
I am thinking that this would be less hassle, however, can anyone suggest or recommend what kind or adhesive or coating I could put on the slabs to set the bottle tops as I would like the rims set within the slab so only the top is showing.
All advice welcome. TIA.
