bathroom floor advice

[sparkydude]

Hi All, right told you i would be back before long. Have bought the tiles adhesive and grout fro the bathrooom floor but now need advise on fitting.

I have all the tools just need to clarify a few points.


The floor is 18mm ply (new) fixed down every 200mm with screws, extra nogins were installed at time of fitting .

I have just read i should have primed the edge and underside of the ply Unfortunateley this is not possible as its now got the bathroom suite fitted to it. I am confident its not going to move so hopefully will get away with this.

I have bought flexible adhesive and grout but just want to know if i should prime the ply with anything before tiling. The adhesive is mapei. I have some primer G for the plaster walls .


Would there be any benefit in using that plastic ply stuff over my plywood to add strength or will tiling direct be ok.

The tiles are cream/white polished porcelain 600x300 from topps tiles. do you recommend sealing or cleaning before fixing or should it be done after fixing and before grouting.

the bathroom floor is not huge approx 4ft square LOL so not expecting huge movement in it


All advice greatly appreciated

Nick

hey sparkydude, use the primer g on your ply, forget the plastic ply!, work tidy and lay and grout before sealing your polished porc, wait until your grout is bone dry before sealing

Hi didnt realise you could use that Primer G on ply but if you recommend it then its as good as done

Cheers

Personally I do not tile on to wood of any kind. There are plenty of alternatives on the market. It sounds like you are doing a proper job with what you have don but if it where me I would lay ditra mat on top of the wood

have to agree with dean dirta matting when tiling on ply , but i am not saying you cant tile on timber use to do it before dirta was on the market and didnt have any problems, and there is a better choice of adhesive on the market now
