What is the best adhesive to attach polystyrene insulation to a painted masonry wall?

Best Answer - Chosen by Voters

I think you might need to contact the supplier as I know for sure that some adhesive properties react with the polystyrene and dissolve it! (on a smaller scale I know that UHU does), the supplier should definitely be able to advise you especially if it is in conjunction with the masonry paint as this will reject most water/liquid based solvents. 75% 3 Votes
