Wall Tiles Not Sticking

[Aztectiler]

I was taught to periodicly remove a recently fixed tile and check to ensure the tile has stuck properly and also to ensure that minimum 80% coverage is being maintained. This is something that I still do on my jobs after being told this over 19 years ago.

a glass suction thingy is good for doing this, rather than risk chipping glaze by prising off witha scraper

What are you using to spread the adhesive on the wall, are you sure the back of the tile is making contact with the adhesive on the wall, are the peaks and troughs in the adhesive flattening indicating contact with the tile or does it remain unchanged.

Are the tiles bent, are the walls flat?

I'm using a notched trowel. Now that you mention it - that is new, and has smaller notches than my previous (3mm ?)

The tiles squish into it (you can see the pattern left).

Tiles are flat, wall is new and flat.

I think it's a curse sent to remind diy-ers that we are diy-ers :smilewinkgrin:

Give the tile a slight twist or movement to work the addy into the back of the tile with a bigger notched trowel 6-7mm

a 3mm is ok for mosaics, but you need to be using a 6mm trowel at least! imo:20:

So... thats your problem i think....Insufficent bed depth and has not got enough grab on the tiles....Also PVA.....:mad2:....never mind it can be rectified....

Deffo up the trowel size tho....and back skimming the tile helps with adhesion...

Ive started to sell minimum 8mm trowels now for walls as tiles are getting bigger, 3mm is defo no good to stick normal size tiles on, maybe you can go down to a 6mm for kitchen tiling with 4 - 6 inch tiles, usually the bigger the tile the deeper the notch you have to fix it with, depends on uneveness of surface as well i suppose, i like 12mm trowels for the biggies about

Ah, that's sounding promising. Will get 'real' adhesive and another new trowel !

Thanks for all the top advice :8:

Will let you know how I get on.
