Hey, i used the unibond poo once, again due to customer supply, they.....in my opinion and only my opinion shounld call it uni****, this description would just about sum it up, i used it over ply as advised and it took 2 days at a conventional thickness before i even dare put my 12 stone on it..... and you should have seen the customer! Anyway that readymix is subquality, for little more money BAL rapidset flex is the way to go. Will it set? yes. how long? roll a dice and multiply it by 2 days, that should be about right... unless you roll a 1!You should get away with it but learn from the experience. as for the pva as primer debate, well they cant get the adhesive right never mind anything else..... in my opinion!:lol:
