The article focuses on the techno-conservation issues of the facade of the residential tenement (kamienica) at ul. Dluga 1 in Gdansk. Its decorations are discussed in a broader context of the finishing works on Dluga and Dlugi Targ streets carried out during the post-war reconstruction of the Gdansk Main City borough. The techniques and technologies of these decorations are examined in the frame of their historical context. The state of preservation of the tenement’s facade is presented, alongside the key damaging factors. The following part presents the initial research results from the tenement’s painting decorations: a plaster composition analysis, a binder type specification and a pigment identification.
