Crack bridging protective coating for concrete.
Sikagard®-550 W Elastic is used for protection and enhancement of concrete structures (normal and lightweight concrete), especially exposed outdoor concrete surfaces with a risk of cracking.
Sikagard®-550 W Elastic is used with concrete repair works as an elastic protective coating on Sika® smoothing mortar (refer to relevant product / system data sheet), fibre cement and overcoating of existing soundly adhering coatings.
Sikagard®-550 W Elastic is a one component, plastoelastic coating based on UV-curing acrylic dispersion with excellent crack-bridging properties even at temperatures below 0 °C. Sikagard®-550 W Elastic complies with the requirements of EN 1504-2 as protective coating.
