In this thesis, I presented a comparison between a microcement system and an epoxy system in order to determine which one provides better protection for concrete surfaces under various conditions. I experimentally tested mechanical properties, water vapor permeability, adhesion to the substrate, and chemical resistance. The results show that the epoxy system significantly outperforms microcement in most properties, especially in terms of hardness, abrasion resistance, and adhesion. However, the microcement system stands out for its high vapor permeability. Based on the findings, I conclude that the epoxy system is a more suitable choice for technically demanding environments. epoksid, mikrocement, poliuretan, vodni sistemi
