How to fix (hide) plaster removed by adhesive tape used to hang a poster

If you want to stick a poster to a wall, using adhesive tape is the first line of attack, but it could give nasty surprises if the plaster quality is less than excellent.

In my case, removing the posters left ugly marks on the wall. In Switzerland people are NOT tolerant at all with these kind of scratches, and you can end up paying several hundred franks.

before the treatment:

To at least MINIMIZE the visual impact of the missing plaster, you can use normal paper corrector liquid, which is very cheap and available in all supermarkets

after the treatment:

Pretty good, uh? Not perfect, but for the price/time invested, the result is amazing.

ok this is a blog of IT, but other technologies are quite fun too...
