We suggest a 28 day primary hydration of concrete prior to Radcon Application.
However Radcon can applied within a few days after concrete pour.
If the 28 day period is reduced to a few days the applicator must be prepared to re-visit after 28 days plus to ensure no new major cracks have formed which may require re-application of Radcon to such cracks and further waterings to ensure a 100% watertight seal has been achieved to the entire area.
