What will happen if.....

What will happen if I use a bag of Ardex na over a concrete sub floor that is 1.45 X 1.25 ie. 1.8 sq. mtrs?

I've knocked up some ceramic tiles in a small hall area and there are a few cavities in the screed, some of them up to 20mm. I have a bag of na waiting to be used and thought mix it all and pour it in:
A. to save throwing half of it away
B. to save having to fill the cavities first.
Any foreseeable problems?

 

probably nothing will happen but latex can soften tile adhesive if any left on floor and going that thick isnt recommended with out clippings but it's been done that thick in one coat before and no problems

 

Is this your own place or customers

 

what's going on top of it mate if it's tiles the screed isn't going to work you need a waterbased one

 

It's for a customer and it will be Da Vinci Karndean.

Thanks for the replies.

 

huh?
What you talking about?

 

Think tarkett was wondering if I was just replacing the ceramic tiles I took up with more ceramic tiles.

 

Done it loads of times John with na. You can add some granno too.

 

Thanks Daz

 

you're right mate
