Air Tight Paint improves air tightness

In recent years we all noticed how important it is, to create a full air tightness strategy, which includes every part of the building.

The more air tight we want to have our building, the more attention we need to put into small details, to prevent the enhanced risk of uncontrolled air infiltration through these areas. 

Spots like chasings for conduits on perimeter walls or junctions between floor and walls are becoming more and more important when it comes to a functional air tightness with values of 1.5 ACH (air changes per hour @ 50Pa differential pressure) or less.

But how can you make certain areas of your house steadily air tight?

By using air tight membranes, tapes or plaster coating?

All three solutions above do create an air tight layer, but for the most cases there is an easier alternative available:
