A few years ago I used a Sika produce on a new screed, it was a two part solution which dried like glass. It was for fast track sealer so I could fit a timber floor on top without any problems with the moisture content of the screed effecting the timber. Do you still do such a product? I'm looking at an area of 110m2


Sika Primer MB may be the product you used? Coverage is 400–600 g/m² so to apply 1 coat to 110m² you would require 44-66kg. A second coat may be necessary depending on your substrate and requirements - see product data sheet (downloadable from the product page) for more details.

questions badral on 10/08/2018

is it okay to apply curehard 24 on painted concrete floor


No, it is for bare concrete only.

questions Andy driver on 08/02/2018

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.
