Same old story... but the answer ?

[Tortoise]

Hi All,

I'm a diy er with a question. I've looked thru this forum for help but I'm still unclear as to the most practical way to remedy a FLEXING floor.

The story so far.... Its a ground floor shower room max. 2 x 2 mtrs.

The floor was tiled with ceramic and grouting was loose(missing ) in the central area
I lifted the old tiles on my floating floor, and I discovered a plywood board surface ( I'm thinking good this will save me some work ).
The previous tiles were laid in flexible adhesive and much of this is still glued to the ply.

I know realise that the floor flexes with me walking on it, but if I use a recommended product will this compensate for the movement ? After all its a flexible adhesive for a flexing floor.

I don't really want to lift the old floor to fit noggins or a sub wall if a new product or method of stabilising the floor is available ?

What can I do about the old glue? Would a latex screed work ?

If I screed the floor, then tile using Mapei + latex, and grout with silicone ( all products would flex and could be the answer ? )

The new tiles are 600 x 300 Quartz starlight, so big slabs for a small room, but solid and less joints so the weight would distribute better.

Help please, to make me sleep easier!

hello there,if you wish to sleep easier then lift the floor and you will need to find a way to stabilise it

none of these products will stiop this im afraid

if its flaoting you may be better with amtico or karndean imo

Floating floor is the clue

I'm with Kilty, if you can feel movement in the floor when you walk on it then amtico or karndean would be better. Flexible adhesive will not absorb that amount of movement and your new tiles will pop if you tile it as it is now.....

Many thanks.

Hi again, I have been thinking of the advice offered to stabilise the floor, and I will be lifting the plywood sheet to see how to firm up the flexibility problems.
Just a couple of queries tho
What about removing the old flexible adhesive ? or should I use latex screed ?
What is the recommended adhesive for laying quartz onto latex ?
Thanks.
