Effectiveness Of Polymer-based Impregnation
Agents On Natural Stones - Long-term Studies

Abstract
In recent decades, polymer-based impregnation agents have been developed with
the aim of reducing the deterioration of natural stone buildings and monuments.
Prior to using these products on historic buildings, various tests on effectiveness
and durability had to be carried out.
The problem of accelerated ageing methods is that they can induce material
damage which is not comparable with processes occurring in nature, but long-
term outdoor exposure is time-consuming and costly. At the Institute for
Building Materials Research an experimental apparatus called "VENUS"
(German anagram denoting 'test plant for the development of realistic
environmental simulation concepts') is used for accelerated, reproducible,
complex weathering. The weathering cycle of the VENUS
