To apply:
My colleague gave me the tip by the manufacturer on the way showers with high humidity to pull the film after, so that the dust is present in every normal household air sinks to the ground and thus no dust on the film holing can.
Said and done,
1. from the pitch (doors and Close any windows before and after the installation open)
2. carrier film removed to 1/4, set and slowly with the aid of a commercial Stickies block (self-adhesive) smoothed
It seemed to me that as if the film has virtually tightened by itself. I highly recommend this cheap but well-made film each of an addiction without hesitation recommend!
