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.

 

[J Sid]

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

 

[Anthony Wills]

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?!?!

 

[Anthony Wills]

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.

 

[Anthony Wills]

Spoken to Glynn in tilemaster technical support who was very helpful. He can't see anything wrong with what I have done. Could be that it hasn't fully cured yet. They are going to test the batch and get back to me.

Decent coverage but there's deffinately some moisture there. A little strange after 3 weeks.

 

[Dumbo]

I'm wondering wether the screed hasn't dried properly and that is why the adhesive hasn't dried .

 

[Anthony Wills]

The concrete has been down for 8 years, but this area is by the front door, and turns out this is also where the cat sometimes decides to empty it's bladder, thought it was a bit stinky I am not a cat fan

 

[GoneGuy]

Is there a draught from front door as well?

How is that a new build then .

Yes there is

Haha, yeah you're right, it's a new build to me as I remember it all being fields. I meant that it isn't an old house, it's an estate that was just thrown up, you know what they're like.

Can't see any issue there ,what is your concern ? If you are looking for a greater bond strength you need to upgrade from rapidflex which is a c2 rapid to a full on S1 like setaflex , the tiles were well bedded and went going anywhere if you had not hit them with a hammer

Cheers for the reply Gary. I was mainly conceded how easily they came up considering I had good coverage and back buttered and have never actually had to take my tiles up before after 3 weeks (well never) so didn't know what to expect. I'm not the most experienced tiler so was just after opinions and advice from the wonderful people on here. I'm putting it down to the adhesive not being fully cured due to time, draft and cat p*ss.

By all accounts Tilemaster adhesive is some of the best product you can use, I’ve never personally used it. If you have mixed and used the adhesive correctly and with clean water of course then I’d be concerned as to why after three weeks it hasn’t cured. Could be one for the lab this one.
