Micky we keep answering your questions and you keep coming back with the same one asked another way. If your not getting enough time out of multi then you are trying to put on too much for what your skill set allows. If your struggling to get it on before it sets you must also be struggling to get a half decent finish as you'll be constantly chasing your tail. Applying thick pva can cause you more problems as the multi can start sliding if it's not properly dry yet. Mix your pva with water and pva it a few times and add creme tartar to your multi. We've already told you.
