Cortec® is pleased to release a new demo video on how to apply CorrVerter® MCI® to rusty rebar! The demo shows how to transform a piece of rusty rebar into a primed and passivated one, as required for good concrete repair surface prep. It is a great resource to share with engineers, contractors, and anyone involved in concrete construction or restoration.
The two-and-a-half-minute demo video covers basic steps of CorrVerter® MCI® Rust Primer application:
1. Remove loose rust with a wire brush and rinse.
2. Apply CorrVerter® at ≈9-14 mils (225-350 µm) wet film thickness (WFT).
3. Recoat 20-30 minutes later if needed.
4. Allow to cure 24 hours before placing concrete.
5. Inspect to ensure full coverage and total cure.
A highlight of the video is the time lapse that shows CorrVerter® MCI® turning from white to black as the primer dries over the course of 4-6 hours. In the process, CorrVerter® MCI® is able to passivate existing surface rust and protect against re-rusting, providing a labor-saving alternative to sandblasting for rusty rebar. The most obvious application is rusty rebar surface prep as a convenient alternative to sandblasting prior to concrete repair. However, CorrVerter® MCI® can also be used to passivate new rebar that may have rusted during outdoor storage on the jobsite.
The CorrVerter® MCI® rebar demo is a fun introduction to the workings of CorrVerter® and is a great way to familiarize workers with the application process before using CorrVerter® MCI® out in the field. Watch the demo now to see how it works! https://youtu.be/4GtnllwpdzQ
