Sikagard®-551 S Elastic Primer is a one-component, solvent containing primer for very dense or very porous concrete surfaces and/or difficult application conditions. Sikagard®-551 S Elastic Primer is part of a system that complies with the requirements of EN 1504-2 as protective coating. - Deep penetration
- Water vapour permeable
- Surface strengthening
|
Usage Priming of very dense concrete and of very porous concrete (having a tensile strength lower than 1 N/mm2) Sikagard®-551 S Elastic Primer can also be used as primer on firmly adhering existing solvent based coatings Sikagard®-551 S Elastic Primer is part of the Sikagard® acrylic coating system: - 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 - Deep penetration
- Water vapour permeable
- Surface strengthening
Packaging 10 l and 20 kg pails Colour Slightly yellowish liquid |
Application Information Ambient Air Temperature +8 °C min. / +35 °C max. Relative Air Humidity < 80 % Dew Point Substrate and ambient temperature must be at least 3 °C above dew point. Substrate Temperature +8 °C min. / +35 °C max. Waiting Time / Overcoating Waiting time before coating: Temperature | Time | +8 °C | 36 hours | +20 °C | 18 hours | +35 °C | 8 hours |
Note: When application is on existing coating, waiting time prior to overcoat the primer will increase by 100 %. Both water dispersed and solvent containing coating system can be used as subsequent topping. Curing Treatment Sikagard®-551 S Elastic Primer does not require any special curing but must be protected from rain for at least 6 hours at +20 °C. |
