polished black porcelain (again!)

no de coupling membrane ......never heard of one ...

the ply is 18mm thick ......and is only under the bath ,this reduces the the leg length on the bath legs ,makes for a flatter floor ,and give somthing to screw the bath legs into .......the cupboards are on two pieces of 18mm blockboard as the leags they came with weren't long enough ,to accomadate the plinths

so is the tiling on to chip board sheets?

 

[nomates]

I originally wanted some tile upstand for skirting ......but the 45 angle kippered me ,as a cut down tile wouldn't be long enough and the grout lines would go out .....so silicone it is ...


LOL @ the white walls ....i'm not sure this was a good colour choice , easy fix if it all goes a bit grubby

 

[nomates]

so is the tiling on to chip board sheets?

concrete floor , then tile adhiesive, then warmup insulation board ,then warmup underfloor heating pad , then more adhiesive ,and finally tiles

hi nomates
you definately need a de-coupling membrane in a situation where you have a plywood floor, with underfloor heating.. the de-coup, combats against lateral movement (side to side movement) due to expansion and contraction via the heat mat and timber!

as for the ply wood, then how you installed it, will determine how it copes with the possibilty of deflection (up and down movement)

 

[Aston]

concrete floor? so why the plywood? why not a backerboard or the likes?

 

[The D]

ok then just ignore me it looked like a wood floor nice job

 

[nomates]

hi aston tiling ........to be clear ......the ply wood is ONLY under the bath and units .....the tiles are on a concrete base .....but thanks for the advice .....the last time I tiled on a wooden floor ,I used a hardy backer board

 

[Scott]

HA!!!! nice one, he got us all!

Concrete floor is fine mate

If you get any trouble buffing off the sealer you can add more to aid the removal/buffing

 

[nomates]

concrete floor? so why the plywood? why not a backerboard or the likes?

for under a bath .......its good for a fixing ,not many plumbers screw the bath legs down....but I like too , the units needed lifting up .....as the legs they came with weren't long enough to accomodate the plinths ,(long story) so I ussed two lots of blockboard to make up the difference ........hope this makes sense

 

[Aston]

nice one nomates
sorry for the confusion.
ed ;0)

so just to be clear...what the underfloor heat on?

 

[nomates]

under floor heat is on ....warm up insulation board ....


should i clean the sealer off the tiles before grouting ,or leave it until I've grouted?

 

[Aston]

good man, i thought you laid the ufh directly on the concrete but you've used insulation boards

all the best
ed

 

[nomates]

cheers and thanks for the advice ,if I get into trouble tomorrow i'll be back

 

[Scott]

Id be inclined to polish it up first then if you get any trouble getting a nice finish after the grout you know at what stage its gone wrong.
