Let the games begin! Any ideas why this has happened?

Yep.

The thing with slc is not to worry about it, follow the instructions on the bag and don’t play around with it.

Mix, pour and smooth out with a spiked roller.

Done the above floor yesterday with Mapei ultraplan perhaps the best slc I’ve used, was able to walk onto this floor without marking it in 4 hours.
The residue in your backed looked a bit off colour.

 

[Bond]

The residue in your bucket.

 

[Boggs]

That’s the fibres.

What did you mix it with, and how long for?

I can see it's the fibres, just curious why it's dried so quickly in that area in particular. Two coats of primer needed?

I mixed with clean water as stated on the packaging

I mixed 2mins at a guess, until the right texture, I let it stand for a few mins and gave it another quick mix.

I did mix at very high speed which I now realise the bag says mix slowly...

 

[Boggs]

But if you only mixed half the bag then the fibre to aggregate ratio is no longer correct meaning you probably have more fibres in the floor than aggregate to set it.

To be honest it doesn’t matter how long it was mixed for or how fast or slow it was not going to be right.

Okay thanks

Okay thanks

Don’t loose heart, wait until it’s set, you’ll know if it hasn’t worked.

Oh I haven't, I'm excited to see what it's gonna be like in the morning. Just trying to learn from my mistakes

The one think that won't change by the morning is that dry oatch near the door frame.

 

[Old Mod]

Kool.
Sometimes things get over analysed.
Hope it works out.

I mix part bags all the time. Experience tells you if it’s too wet or too dry. Did you let the mix stand long in the bucket? It looks fine to me on the floor. With renovation screed I always use eco prime t although it states primer g is ok in certain circumstances.
As Marc says don’t worry about it tonight if when you next walk on it it’s solid enough and a light poke with a scraper can’t do too much damage to it it’ll be fine.
What tiles are you laying around the toilet?

 

[JordanLincs]

To my knowledge I only let it stand for a few minutes.

Im bit confused as to the difference between Primer G and Eco Prim T.

I'm using 330x330 gray ceramic tiles

Eco prime will help it stick better to the floor as it’s a water based compound. That’s not to say it won’t stick with primer g, I think you’ll be fine.
