concrete repair

[Matty A]

I have a concrete floor to repair before i can tile would any one recommend BAL Quick set cement or just a normal sand cement mix if so what ratio (sand:cement)

[Concept PHT]

4 parts sand - 1 part cement for large/deep areas. for cracks, use a runny concrete mix.

New adhesives on the market can do the job as well (PTB) Pourable thick bed can be used up to 28mm thick

Depends how big the floor is & extent of damage. Another option may be to self level the lot after doing dsome primary filling in of the holes. Mapei Ultraplan ECO is fantastic. Will level up to 10mm in one application, flexible, quick setting, no need for much trowelling levels itself if you use 5.5 litres of water per bag. Around £18.00 a bag, but saves a lot in using extra adhesive to get floor level. Also saves in time as the floor will be perfectly flat.
It's just a suggestion.
