Will the BISK FEST glue leave any marks on the wall?

The BISK FEST glue does not leave any marks on the wall after the disassembly of a glued item. It’s enough to heat the place where the paste was with a hair dryer. Intensely heated, the remnants of the paste left on the wall will degrade and fall out of the wall themselves. If anything is still left, just scratch it lightly off with a scraper or clean with a wet cloth.
