I do a lot of work for one particular bathroom firm , and despite many requests they keep using 25mm MDF for constructing shelves and misc , other bits and pieces . Is it me or is the standard MDF a big nono as a tiling substrate😛rrr:
Yeah , of course , just wonder sometimes if we get a bit precious about these things,
28 years maybe , but a lot of that was as a stone and terracotta floor tiler . Only 2 or 3 years as a porcelain wall tiler
Hi Dan , I subbed to Fired Earth for about 25 years , and that was mostly natural flooring and handmade wall tiles.
Didn't do a lot of high volume wall tiling ,because the bathroom fitters usually did it.
When I left FE , had 8 or 9 months off looking for something else to do , but gradually picked up a client base as predominately a bathroom tiler .
It's a no no unless it's the new waterproof MDF! Don't laugh there is such a product but it's very expensive. Got a mate who built a window and frame last summer and used it in an extension. North facing window with no paint or any finish on it. Looked at it last week solid and bone dry! I have my doubts as to how long it will last though.
Looked at a kitchen floor years ago & the "German" guy had done his own floor prep with 18mm mdf.
Told him no chance & he says that's what they do in Germany & they paint this stuff on it 1st to waterproof it, yip you guessed it a big tub of PVA.
Left him the number of Bal technical & never heard back from him.
i will never tile on mdf. and i instruct the builders to use plaster board , or even better cement board, obviously they go down the plaster board route
