Can gutter get clogged with standard IG2™ micro mesh installed over it?
It would have to be an extreme situation. Not even grain of sand comes through standard IG2™ micro mesh with its 0.0041 inch (0.1mm) opening size holes. However some dirt, such as dust does come through. Now, whether gutter will get clogged under installed IG2™ micro mesh or not, it will depend on whether running water inside of that gutter will periodically flush that gutter clean to avoid clogging. This is the nature, and it applies to every gutter guard. The bigger the opening the more dirt may get through, so more running water is needed to periodically flush the gutter. Under installed standard IG2™ micro mesh, it is practically impossible to reach big enough dirt accumulation to clog the gutter.
