Self level compound poor job?

[VT23]

Hi my tiler screeded my bathroom floor 4 days ago and it hasnt fully cured in places. There also a white powdery residue on top.

In some places where its thinnest it has set. In other places not so well - you can walk on it but i tried scraping some of the white residue and slithers of screed would come off with it.

The temperature in the bathroom has been about 17- 18 degrees. There's no heating in there yet.

He used Nicobond Fibre Flex.

Do you think the mix was too wet?

Sounds like too much water in the mix, if it's not dry after four days there's something very wrong, no fixing it now, all up and start again I'm afraid...

Poor air flow, too much moisture or poured exceeding the thickness that leveller is rated to or a combination of those. Any photos ?

Hi LocalTiler,

You might remember my post regarding my woes with Warmup DCM PRO. Well Warmup recommended that i SLC over the thermal insulation baords before relaying the matting.

So i got a tiler rnd to do it. See below for images. the first 2 where taken 10 minutes after the pour. The last one was taken a few minutes ago. I was surprised at how much surface water there was! 1-2mm sitting on top. The tiler didnt open the window so i had to wait 3 days for it to dry up enough to walk on before i could reach it. The door was left open.

The lumps in the photos are unmixed compound. My tiler said to chisel them off when dry. Surely this isn't right!? You may notice i started doing this in the last photo. Some of the marks are scrapes (top left). I did this yesterday (3 days after application) and had to be careful not to scrape off chunks of compound.

Im panicking at the thought of having to redo this!

Looks like it’s been mixed by hand.

Not been mixed mechanically and too much water is my bet

I think I would hook it up now . It will be easier than when it is dry . The longer you leave the harder it will be

Surely a call the Nicobond technical in morning and then to the tiler?

If your ‘tiler’ tipped it, then he should sort it ( lumps and all) before you put your boards down. Any tiler worth his salt would prepare the whole job!
