Description
Benefits of Cemcrete Concrete Hardener
- This product is mineral based and thus unaffected by UV exposure
- Suitable for improving the quality of concrete floors in factories, warehouses and any other area where hard non-dusting floors are important
- For improving the hardness and denseness of concrete and reducing its permeability
- This cuts down dusting, improves resistance to staining from oils and other spillages and provides a harder wearing surface

FAQ
Q: Can I apply Concrete Hardener to a wet area?
A: No. However, if it is slightly damp (but looks dry) then you can apply it but the surface must not be saturated with water. The surface must have a certain degree of porosity so that the Concrete Hardener is able to find the pores/cavities within the cement matrix.
Q: My builder has left me with a screed that can be scratched away with my finger and is friable, will Concrete Hardener provide me with a hard solid screed?
A: Concrete Hardener relies on the free available lime within your screed to initiate a chemical reaction that densifies your screed surface. It will not compensate for the lack of cement used in a screed mix. In this case it would be better to replace your screed.
Q: Can I apply this myself or do I need a builder to do it?
A: Yes, this is suitable for DIY applications.
Q: Will Concrete Hardener work on a previously painted wall?
A: Only if you grind the floor to the point beyond where the solvent/carrier of the previous paint has penetrated. This is normally 2mm to 4mm depending on what coating was used.
