Vetonit remokor NS-40 — fast class R3 finishing mortar for work in frost
Rapid-hardening fine-grained class R3 mix for urgent repair and finishing of reinforced concrete on walls and ceilings at temperatures down to −10 °C.

Vetonit remokor 05 is a dry mix based on Portland cement with redispersible polymer powder and corrosion inhibitors that performs two tasks in repair. Rebar cleaned to Sa 2 or St 2 is coated with it using a soft brush in two applications, and on dampened concrete it is applied with a stiff brush as a bonding coat onto which remokor repair mortars are placed “wet on wet”. The compound is universal for the whole series, is used under chloride attack and on overhead surfaces, and is permitted in tanks with drinking water.
