Tiling on a suspended floor

[mikethetile]

Mike, thanks - i'll look into it. Will probably go with the retiling still as most of the tiles will be reuable and I like them. Have to see how we can best do this and if the builder will actually come back.

Dave - could you please recommend someone in the SW London area to do an inspection?

Many thanks

very wise Sukie

im pleased your still thinking of tiles, the other options are ok but its not what you wanted and no where near as hardwearing in a kitchen as tiles

Doug, when they fixed a row of 8 tiles last month we only lost one tile - the one they had to crack. With the rest, the adhesive did NOT stick to the back of the tiles. No cleaning was required. The adhesive bearly stuck to the plywood either. I just used my hand to gently push it and it came unstuck. No tools required. I captured this on my phone if you would like a look. Did the adhesive dry too fast? We only gave it about a week before the ufh was turned on. The builders told me a couple of day was sufficient. I now know it should have been at least two weeks.

my mistake Sukie, if they'd been stuck down correctly, it would have been a beggar to clean them, I should've said:smilewinkgrin:

 

[mikethetile]

ive a feeling they used dispersion as they are obviously clueless when it comes to tiling:yikes:

I dont know the correct way but what if you just strengthened the floor as best u can for vertical deflection,maybe with 18mm ply and then then another layer diagonally covering all joints of previous layer(screwed and pva).then ditra ontop.?

 

[Sukie666]

That was a consideration but with a wet ufh system, blindly screwing down the layers of plywood would be asking for trouble. If there was something I could use to glue cross ply that would be better.

 

[mikethetile]

no it wouldnt brace the floor, it would still deflect

Sorry just seen this.. will ask someone in your area to contact you.

Without seeing the results of the tiles that were refixed by your builder I would have to question the total load on your suspended floor. A central island with a large weight of worktop will have a considerable effect on the deflection issue. Did your builder or kitchen company supply you with the relevant weight and required support figures and was a structural surveyor consulted.
Although you certainly have a issue with the method of fixing and preparation for the tiling, retiling with additional support may not be a satisfactory answer to another problem.

Dont use pva.
