Floor tiles lifting after laying. Please help

[Matt]

I did alittle research on the Evo Stik Tile a Floor - Stone and Porcelain and couldn't really find much information. It says it's suitable for wooden floors but it's not very specific. I.E, most adhesives will say use 15mm ply etc. But this one just says "suitable for wooden" floors :yikes:

Thanks again for your replies.

Captian slow:
I just applied the adhesive to the flow and used the notched trowel at 45 degrees, laid the tiles down with a little pressure ensuring it was flat with spirit level at times.


Matt 257:
Thanks for taking time out to check this out. I checked out their website and there was not much just said ok for ceramic and wooden floors.

I think I will be looking into the mapei adhesive as timeless john suggested or perhaps the BAL adhesive products. Just rather frustrating that tiles were nearly all laid. However, I guess it is better than to have grouted and then couple of weeks later have it come up. Lessen may be to not try and cut corners with cheaper materials (adhesives) to save a couple of quid. It has now cost me £75 as I have ripped all the tiles up. But anyway you learn from your mistakes. Not completely blaming the adhesive as there have been some good reviews. But something has clearly gone wrong.:mad2:

Regards. Kevin

If you decide to go for Mapei adhesive and have a Tile Giant close to you. Pop in and mention the Tilers Forum, they will look after you 🙂

 

[Matt]

Before you start relaying, I would make sure your substrate is sound, because if it wasn't a problem with the adhesive, the chances are the same thing may happen.

Thanks Matt257. There is a tile giant near by which I was going to pop down later🙂
I think I will place a few more screws in but I thought 250mm gaps should have been sufficient. There doesnt appear to be any movement

Is it ok that I applied BAL SBR to top surface and sides. I'm now reading in more posts that it should be underside and sides? The reason why i placed in on top is that I thought the adhesive can draw moisture from the ply and it also acts as a bonding agent!

Just need to finish up clearing old adhesive off floor and tiles. Half way through. Did i need to apply another primer/bonding agent as there is now a thin layer/coating of adhesive on the surface of the wood or can the new adhsive go straight on top?

Cheers

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.

Which is your closest Tile Giant?
