if that white stuff that looks glue is actually what i think it is, then will need to contact the planning dept of the local authority to check that is a suitable substance to be used in such a way.
I am talking from experience here as i have just constructed 4 new 5 bed detached houses made out stuff that i find in my neighbours recycling bin every second wednesday, for example, old cider bottles, baked bean tins and margarine tubs, yes i have had the same problems as those people on the dump i.e- leeky roof etc. but fixed it with the labels off the jam jars my neighbour throws away, i have told him how useful the things are that hes throwing away and have also shown him my new housing project but to no avail, he still throws all this useful stuff away, mad!!!
