Thanks GUYS

PVA and MDF:yikes::yikes::yikes: both serious no no's in tiling installations

 

[nybor62]

no deffo not mdf is no good to tile no matter what you treat it with , it needs to be removed, and why mdf is in a shower area is beyond me , crazy who ever installed it there

have you not just sposted this with different wording 5 minutes ago?

 

[nybor62]

oh and pva as no place with in the tiling industry, and i dont think it would be nice to bodge it just so you can rent it out , just creating a massive problem which will cost loads in the long term

yes he has

 

[kilty55]

in that case then yes you can tile it but it still wont last 5 minutes:smilewinkgrin:

Same as NYBOR totally agree MDF is rubbish and is not suitable to tile on no matter what it is primed with, you need tile backer board or very good marine ply. otherwise the tiles will just blow again.

I take it you took the usual landlords route.......the cheapest option.

got to agree with all the advice above...NO to MDF and NO to PVA.

Two options - 1)cheap in short run = do as you have stated and then retile in a couple of weeks (which is more expensive in the end) or
2) more costly in beginning = rip it out and start again doing it properly and then not have to worry about your tenants ringing you up next week

Not all landlords take the cheapest option so dont make assumptions Dom, in my book your out of order. They have asked a simple question.

Lets not fall out.
The chap asked for a bit of advice and hase been given sound advice as retiling onto the MDF will only cause further problems and possible leaks, damp and rot behind and below the shower. Its their house and their call.

Only do it once more, do it right and if your still not sure how to proceed, get a pro!
