I tend to use no more ply for bathroom floors. The mega strength adhesive is quite expensive, I just wondered if anybody else uses flex tile adhesive to put this down or any alternative like grip fill??? would this have the same results as no more plys product.
I,ve been meaning to try hardie for a while, but local tile shop doesn't supply it... Just been doing a search and have found a local-ish builder merchant that sells it. May give it a whirl..
As David says, if you dont use the Mega Adhesive it may negate the warranty, Ive done price comparisons with NMP v Hardie and it still works out a better price.
