Hi, I have been asked by a customer to clean the patio. I wanted to use Hypo but she has a gravel resin pathway that is below the patio that i will be cleaning, therefore this resin pathway will be in line with the run off from the patio above and was not sure if this was safe to do. Please can anyone advise regarding this. thanks in advance

Never had any ill effects myself. Speaking to a rein bound contractor at Christmas and he said do whatever you want to it after its been down 24 hours - I cleaned it after it had been down 3 days after the landscapers had run mud everywhere

If I've read it right you are intending to use hypo on a patio but you are worried about the runoff onto the resin bond path. If so to find out for yourself if hypo will damage that path why not just do a small test patch of neat hypo then see what happen. If it fooks it up then you will know  for sure not to use it on the patio. That is what I would do anyway. lol
