In order to prolong concrete durability, polymeric coatings are commonly used. The coatings protect concrete against ingress of hazardous media. The coatings have to be characterized by long-term weathering resistance, good adherence to concrete substrate and appropriate elasticity to have crack bridging ability. Ensuring appropriate homogeneity of the material is very important for obtaining high quality of hardened coating, especially while comparing some features of the material under laboratory conditions. The paper deals with comparison of some properties of acrylic coating such as displacement and damage energy depending on a preparation method (with and without deaerating) and a type of a agitator used.
