Protection of leather bindings from the influence of an unfavorable environment is one of the most important tasks of conservation. One way in which this is accomplished is by treating the leather part of an object with an oil or lubricating dressing. The purpose of the work is to study the influence of greases (oiling compositions) of various compositions on leather properties during ageing process (water-absorbing capacity, hygroscopicity, elasticityand color change). Ten oiling compositions were investigated.

The study of fungal resistance of five paint coatings and three biocides by different methods was carried out using both individual cultures of micromycetes and their mixtures as test cultures. It is shown that the data obtained by different methods is almost identical, which makes it possible to use less labor-consuming and cheaper methods in establishing the fungal resistance of paint coatings and biocides.
