Sikagard-550 W Elastic is a one component, plasto-elastic 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.
Usage
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- Suitable for protection against ingress (Principle 1, method 1.3 of EN 1504-9),
- Suitable for moisture control (Principle 2, method 2.3 of EN 1504-9)
- Suitable for increasing the resistivity (Principle 8, method 8.3 of EN 1504-9)
Advantages
- Crack-bridging even at low temperatures (-20°C)
- High diffusion resistance against CO2 reducing the rate of carbonation
- Water vapour permeable
- Very good resistance against weathering and ageing
- Environmentally friendly (solvent free)
- Reduced tendency to dirt pick up and contamination
