New Floor Tiles Lifting

[Johnboy 2]

Hi guys, hope you can help. I have been having a bathroom refitted by a local plumber who also fixed the ceramic floor tiles, around 45no. x 33cm x 33cm. After just a few weeks the grout is cracking in an area and a couple of tiles seem to be coming loose. I am a joiner and laid a new chipboard floor, I know this it not an ideal base but there was no choice as the old one was shot. The joists were fine, usual set up but I even supported each one between sleeper walls to ensure they were solid as possible, packing straight. The 22mm flooring grade chipboard was glued together, screwed well down and covered with 10mm resin bonded external ply, also screwed well down. This floor is as solid as this type of floor can be. I go on about this because I am sure this is not the problem. The tiles need to come up, any advise will be greatly appreciated, Thank you.

Would never tile on to any sort of wood on floor or walls, let alone in a wet area.
Was a uncoupling membrane used?

Tiles up, clean of adhesive if any has stuck to the floor, check floor is solid and deflection free and relay using a uncoupling membrane.

Do you know what adhesive was used.?

What best adhesive would you reccommend fot this application?. Thanks

 

[Dave]

It could simply be the adhesive type or incorrect bedding ... If you lift some tiles and post a pic of what's underneath..

Hard to tell seeing what you do...

Also the ply isn't really the correct thickness but if the deflection was zero , this doesn't explain what it failed so quickly , hence me mentioning adhesive type.

if your tiling onto ply theres only one addy I would use that's bal flex 2part addy had to take a floor up 3 weeks ago which was stuck down with this addy took over3 hrs with sds to remove 3 mts sq its a rubber based addy
but to be honest haven't used for several years and not sure if bal still do it, was very expensive addy.

The same with Ray. Fastflex all day. Rubber crum adhesive designed I believe to tile London Underground due to the vibrations. Tiles still haven't moved decades on.

I'm surprised even a sds got them up I bet it made a right mess.

Some 2 part cement based adhesives are pretty good these days by the looks of things but you could tile curtains with Fastflex and the tiles would stay put.

Welcome aboard. Please register!

Thanks, all I can fine is Bal Supercover Rapid Flex, states ideal where vibration, underfloor heating, shrinkage or deflexion is possible. Would this be suitable?.
Cheers

Thanks for that, I will post a pic when I get one up for comments before proceeding.

Is there a professional tiler member local to Bridlington that could possibly have a look at our problem?.
Thanks

The tiles come up whole, easily with just mainly a a paint scraper, the ply base easily cleans up, seems no real adhesion???

Do you think it's an adhesive problem?.

with out a doughty m8 the addys sticking to the tiles but not the ply . I would remove all the tiles take up the ply and ether stick and screew hardy backer board or use a decouljing method, ie ditra matting
if your a trades man im sure you could relay this your self especially as there coming un easily. may be using the same tiles if you remove the addy from the back of the tiles there already cut to shape . replace ply with h/b board . then re stick with a s1 addy get a 8 mm trowel and antie s your bob.

The adhesive is called bal single part fast flex it was a 2 part adhesive but you just mix it with water now.
It will still stick wings to an aeroplane though and is very flexible.

Can't take up the ply without stripping all the new bathroom as in image.

Get nifty with a saw, you can cut around the bath and perimeter, and then lift the loo.

Alternatively, I'm wondering if you can pull up the tiles and then cut wedi board and screw to the dodgy ply? Not sure if that meets regulations and whatnot but I'm wondering if it would work, maybe the professional lads could confirm?

 

[johnboy 2]

Cutting really wool weaken the structure of the floor, the ply isn't dodgy at all?????

 

[Dan]

Ahhhh sorry I just read the thread properly again. I thought it was a ply fail situation.

 

[johnboy 2]

Going to bite the bullet, went today and got some replacement tiles, the supplier said the very best for my situation is Bal Rapid Flex Fiber plus, Bal Acrylic primer, with Bal Micromax 2 grout Do you pro's agree before I start?
Thanks
