Ordered directly from Finja. 650 kr for a sack of R50 and a bucket of slamma.

Can it be done as a private individual?

Can it be done as a private person?

Yes, in my case the nearest building supply store got the product in for me. They are resellers of Finja.

Oh, so you went via the bygghandeln, I understand.

@Gabsson Did you paint on korrohäften? It looks quite glossy when it has dried. Doesn't the datasheet say anything about whether it can be painted over?

Yes, you can paint on korrohäft without any problems.
Did you use zinc spray or something similar on the reinforcement? (It's not really needed but I did it as extra protection).

Basically, korrohäften is just a regular cement slurry but with the right alkalinity to stop corrosion of the reinforcement.

Got it! Should have studied more chemistry.
