This is my edpm rubber . So stuck to stone before flashing ontop . Could just use ‘any old expanding foam ‘ but just wondered if there was a super delux version . Ct1 tricky as surface isn’t even so need to ‘expand’ to fill the gap.
Expanding foam has been my friend for many years - helped me out a good few tight spots .
But I guess they are not all equal ?
I want to bond rubber to stone externally . So want permanent ‘grab’ but also water / weather proof .
Any recommendations ??
