Tile Underlay...alternatives?
Im doing some tiling over cypress pine and will need an appropriate tile underlay. I can buy some at the elevated cost of $30 a sheet out here in the boonies, but Im wondering if theres something just as good and cheaper?
Villaboard i thought may be good, however JH's website say not for floors....
Also, if i did use tile underlay I understand I will need to seal it...so whats the difference between something like villaboard and tile underlay if I still have to seal them?
thoughts....?
