Abstract: Statement of problem Hardness of soft relining materials is influenced by different solutions, coatings and physical procedures. Purpose To estimate the significance of different treatment procedures to the change in hardness of SRM. Materials and methods A total number of 360 test samples were made and divided into 12 groups. Results The highest values of hardness belong to Mollosil, covered with sealer after thermocycling. The VPS materials are less affected by different ways of treatment. Alcohol has a deteriorating effect to the SRM, especially the PMMA ones. Conclusion After application of a sealer the hardness of the test samples increases at an average of 2 max 3 units in Shores scale (for both of the testing groups). The sealer protects the SRM from disintegration, that is way it is strongly recommendable to use it in order to elongate the durability of these materials.
