Abstract
This paper presents the results of the experimental researches regarding the influence of the composition of some film-forming polymeric products for the protection of concrete on certain of their characteristics. Thus, there have come into prominence the film-forming products based on acrylic resins with superior characteristics by comparison to the film-forming products based on acrylic-styrene resins. Keywords: film-forming product, acrylic polymers, concrete, covering system, acrylic-styrene polymers
