Wall Tiles Not Sticking

[Tambo]

is there a profile at all on the back of the tiles?

There's a diamond patern of ridges on the back.

Don't seem dusty at all.

As a keen amature (read moderate diy-er) my next thought was to apply the adhesive to the tiles rather than the wall. Know it's not the done thing, but it would answer the question - will it stick to the tiles. :dizzy2:

You could apply to the wall and then give the tiles a thin skim on the back before fixing to the wall

ditch the unibond mate its gash

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?

1. that's your back profile
2. that's called back buttering,quite common actually, but you still need to apply combed adhesive to the walls

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

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:
