F44 will stick risers. We are not talking walls here. And yes i know what Fball say, i have worked with them on product development and adhesives for many years gone by. It is your responsibility to make sure if you are using a harmfull product that people around you are protected other wise you are liable. Im advising you on what you should be doing. What you decide to do yourself is up to you but we cant advice using fans etc and not using the correct PPE on a forum that someone may read and then start using the stuff based on incorrect advice.
