is it okay to apply curehard 24 on painted concrete floor


No, it is for bare concrete only.

Hi can you put a paint over the top of curehard 24 if so what products would you use


Sikafloor CureHard 24 cannot be overcoated, it would need to be mechanically prepared by way of blasting before a coating system was applied. 

questions julian jones on 06/07/2015

I am looking at roughly 600m² of powerfloated concrete. Firstly I am going to degrease then lightly abrade the surface (as spec'd by Sika) before applying 2 coats of Sikafloor CureHard 24. Would you have more of an indication as to the meterage per litre based on this spec?


We would recommend working on 5.5m² per litre/per coat. This would mean you would require 220lts (9 x 25lts) to apply 2 coats to 600m².
