Floor tiles lifting after laying. Please help

[Smithy153]

Just a quick question when your popping the adhesive up does it look like it has stuck more to the floor or to the tiles or is it pretty much equal. This may help diagnose the problem.

As it looks like it could be failed adhesive I would try and get it all off imo.

if there is a coating of adhesive still on the floor it must be movement or skinning more likely movement ete

Agree with above poster sounds like the adhesive is skinning over before you lay maybe mixed to little water or waiting to long before laying tiles you have to remember adhesive skins over double quick in hot weather . also i personally think evo-stick is absolute pony steer toward mapei/bal.

it is mixed some on tiles and some floor. Have removed as much as possible but still adhesive residue left.
I think that maybe the adhesive was left too long to apply at times and it was very hot in the room. This is probably one of the main contributory factors now i thins. Anyway once i get some of that Mapei adhesive i will ensure that i either get slow drying or get it down quick in the evenings when it is cooler.

Thanks. I just wanted to check what they had in stock before you made the trip. They have Keraflex Maxi (White and Grey) in stock. Keraflex Maxi is a flexi adhesive that will do what you need to. It also has an 8 hour pot life and open time of about 30 mins which will help a great deal in this weather. Good luck with the job

Thanks matt257

You have to use rapid set on timber not slow setete

Keraflex Maxi is suitable for Ply

Why would you need to use Rapid Set?

moisture content and the way it sets

Not heard that before, thanks. I always thought that because a cement based addy doesn't use dispersion to set, that even slow set would be ok for wood. So is no slow set ok for wood even though Mapei say Keraflex Maxi is?

I would be looking at that floor first, It sounds suspect to me, go over it with a fine toothcomb and make sure their is no bounce at all, you must use the correct addy, do you know a tiler that could give you some info by looking at it for you, you have wasted money already on addy already, if your definately not getting a pro in to do it then a few quid as a tip for a bit of knowledge seems a small price to pay to get you on your way ( i'm a poet )

Bal flex is not rapid setting adhesive and is absolutly fine for timber floors though it is recommended that a primer is NOT used prior to fixing, if you want a faster set then bal rapid flex is the way to go but it does not have to be rapid setting for timber floors just flexi.

But if you can see the floor flexing when you press on the trowel then you have a deflection problem with the boarding which will need sorting first.
