Ok, before you all start saying this is a bad idea...i realize this isn't the best or preferred method of doing a counter however, the counter was custom built and is to wide for a standard prebuilt throw in solution. The whole kitchen is seriously outdated and just needs to be gutted and start from scratch but we don't have that kind of money right now. I don't want to put in something that 5-10 years from now when we rip it out, I don't fret over the wasted money so... here's my question.
Do I have to use backer/cement board on top of the plywood? I'm hoping to avoid this purely due to the fact that the counter is already unusually tall (which at 6'6" I love) and theres not much room between the surface and over head cabinets as it is.
Could I get away with just using some sort of waterproofing/de-coupling membrain such as ditra? I realize use of this product brings me up to around the price to relaminate, other than the fact that I have left over from the bathroom floor...
Thanks in advance!
