"It has been stated in these forums that No More Ply correctly laid with the correct adhesive adds sufficient strength to a floor but as yet we have seen no technical data to back this up."
I have used it allot and it does make things very solid but you do have to follow the instructions to the letter especially the bit about wearing gloves when using the super strength polyurethane adhesive that stuff is evil takes weeks to get off and even then it's your skin that takes it away.I am sure it is Gorilla glue in a different package.
Also the no more ply screws are worth using as they self tap much better than cheaper alternatives from screwfix etc.
But it's not cheap and it takes time that what this thread is about finding a faster reliable way.
