Namen diplomske naloge je najti učinkovite metode za odstranjevanje grafitov z arhitekturne dediščine mesta Ljubljana. Raziskava temelji na praktičnem preizkušanju metod odstranjevanja grafitov z mineralnih površin. Med preizkušenimi površinami so bili upoštevani najpogostejši materiali, ki so gradniki kulturne dediščine v Ljubljani, in sicer omet, kamen in beton. Glede na podatke, pridobljene iz opazovanja z grafiti popisanih stavb v Ljubljani in informacij, prejetih od uradnega distributerja podjetja Graffiti Slovenija, smo določili najpogostejši barvi, ki se uporabljata za napise – to sta črna in rdeča. Preizkusi odstranjevanja grafitov, ki so obravnavani v nalogi, so vključevali omenjeni grafitni barvi v razpršilcih z različnimi vezivi: akril, akril na vodni osnovi in alkid ter dve vrsti markerjev – alkoholnega in akrilnega. Metode odstranjevanja grafitov, med katerimi lahko izbira konservator-restavrator, vključujejo več možnosti: mehansko, kemično in lasersko odstranjevanje. Rezultati metod odstranjevanja grafitov so razvrščeni glede na učinkovitost v smislu časa, stroškov in stopnje varnosti metode za površino z grafiti popisanega objekta.

• Title: Removal of graffiti from mineral surfaces

Abstract

This work is aimed at finding effective methods for graffiti removal from the architectural heritage of the city of Ljubljana. The research is based on practical testing of methods for removing graffiti from mineral surfaces. The most common materials on objects of cultural heritage in the city of Ljubljana were considered for the removal tests: plaster, stone, and concrete. According to the data obtained from the observation of graffiti vandalized buildings in Ljubljana, as well as the information received from the official distributor of Graffiti Slovenia, we determined that the most common colors used for inscriptions are black and red. Graffiti removal tests discussed in the bachelor’s thesis included graffiti spray paints of those two colors with different binders: acrylic, water-based acrylic, and alkyd, and two types of markers – alcoholic and acrylic. Graffiti removal methods from which a conservator-restorer can choose include a wide range of options: mechanical, chemical, and laser removal methods are considered. The results for each method are ranked according to efficiency in terms of time, cost, and degree of safety of the method for the surface of the original.
