Description

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.

Uses

• 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
