Your thoughts on coverage?

[Anthony Wills]

Hi
I layed 4 tiles for a customer in a front door entrance. The customer then wanted me to rip up the carpet and tile the whole hallway in the same tiles. This meant taking up the tiles I layed. They came up with no difficulty and saw there was pretty good coverage in under most of the tiles imo (pics atached). I used tilemaster rapid flex and a 14mm solid bed trowel. What do you guys think of the coverage and would you continue with the 14mm solid bed or used a 12mm notched? 450mm glazed porceline tile.

Concrete screed in a new build which is pretty level and in good condition. Thanks in advance

When did you put the 4 tiles down..?

About 3 weeks ago

if mixed correctly I would have expected better from a rapid setting adhesive, but haven't used tile master produces.

Same here, they appear to have come off very cleanly perhaps suggesting the adhesive has set before bonding with the tile.
What substrate are they on?

3 weeks! Those tiles shouldn’t be coming up in one piece! Looks like you back buttered too.

looking at the colour, to me it looks like it's still drying and hasn't reach full bond strength yet.

Thanks for taking the time to reply. Yes I back buttered too. I was a little concerned on how easy they came up. Strong bond to the concrete but not the tile. Bit worrying really. So suggestions are; not mixed correctly or maybe started to go off prior to laying the tile, although I did lay straight away?!?!

I might send some pics to tilemaster and see what they say

Got to agree with Julian. Doesn’t look to be fully cured.
In good conditions, cement can take 28 days to cure fully.
