I am installing a non-easy plumb screwfix shower tray onto newly laid 18mm chipboard. There is about a 15mm drop between back to front and was wondering what the best way to level it off would be. I was thinking of packing the lower end but also putting down a layer of cement/sand to strengthen it or is it best to lay a wet mix, if so what would be the best mix to use and do i need to add pva?
Thanks for the reponse garnico1307, i had laready checked the projects page out and have searched extensively on the web. I can see that i will probably have to put a cement/sand mix but can't find any advice on a mix, should it be a dry mix or fairly runny etc.
