Tiling

can you sand and cement over floor tile adhesive

Anonymous user 23/02/2024 - 3.01 PM

The floor has only been tiled recently but noticed after a couple of days that the tiles started to crack. I did mentioned to my tiler about some part of the flooring that was uneven but he said the tiles would be ok. Right now, I am not too pleased with the outcome. I have now removed all tiles but the adhesive is proving to be very difficult to remove. I have taken up quite a lot but getting a bit tired now. I have already bought some levelling compound but was wondering if that would cover the adhesive already there or should I sand and cement over it.

Are you a tradesperson and able to answer this question?

It depends how thick the adhesive is. Self levelling compound can only get over so much. Say around 10-20mm. When you say sand and cement I'm presuming you mean screed. The minimum depth of screed should be no less than 60mm. If your existing floor is lower than the rest of the house then this isn't a problem. However if this isn't the case then you will end up with one floor higher than the rest. Use a professional!

An answer from a tiler, not a plaster.....yes you can self level over the adhesive as long as its not loose. Many self levelling compounds will go up to 80mm in one pour, bal level max for one. You need to read the instructions on bag and on the website with regards to primer and product suitability re substrate

No, covering one problem with sand and cement or screed will cause another in the future. You should think or try to find answer to why this happened. Did the tiles was installed correctly ? ( Not dot and dab for example ) ? Did the floor was prepared - probably not because is uneven. Is there any movement on the floor ? What type of floor do you have ? If its suspended timber floor for example and was uneven or it is bouncing it will happen again if not prepped right. But this is one scenario only.
