Stabilization, Conversation and Strenghthening of Historic Plaster Using Nanofibres

Abstract

The paper deals with the stabilization, conservation and strengthening of historic plaster fabrics based on nanofibers. As a result of degradation processes, especially of a chemical nature, accompanied by increased humidity of historic masonry, there is a loss of cohesion and a disturbance of the surface finish and plaster. Traditional remediation techniques and methods normally lead to a reduction of diffuse permeability in the multiphase structure and create different expansion properties under the plaster. The undesirable feature of this method is its irreversible character. Currently there are a number of primarily preferred procedures that stabilize the structure of the external finish, yet at the same time preserve the original features of the historical plasters. This paper will list the partial results of the ongoing in-situ and laboratory research applications of fabric based on nanofibers formed by the supporting layer and spinning polymer.
