Product Description
Sikagard® 551S Elastic Primer is for very dense or porous concrete surfaces or difficult application conditions.
Sikagard® 551S Elastic Primer is a one component, solvent containing primer which provides deep penetration yet is water vapour permeable, whilst strengthening the surface.
Best Uses
Sikagard® 551S Elastic Primer is a priming solution designed to provide adhesion and bonding power to surfaces that are extremely porous or dense and can be difficult to coat. Sikagard® 551S Elastic Primer can also be used as a primer to firmly adhere to existing solvent based coatings.
- 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 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)
Application
Sikagard® 551S Elastic Primer can be applied using a brush, roller or airless spray. It has a theoretical coverage rate of 7-10 square metres per kg. Sikagard® 551S Elastic Primer can be overcoated after 18 hours (at 20°C) with Sikagard® 550W.
Surface and Environment
Sikagard® 551S Elastic Primer has been designed for use on porous or dense surfaces (primarily concrete). It is suited for application in adverse conditions, offering good strength and deep penetrative qualities.
