Technical Specifications

Data-driven answers based on official SG211 laboratory tests.

Core Performance

Laboratory tests show it penetrates C40 concrete up to 6-10mm deep, forming an internal hydrophobic mesh structure.

No, it is a clear, milky-white liquid that penetrates deeply without producing any color shading or altering the natural appearance of the surface.

Application Guidelines

Surface drying typically takes 2 hours at 25°C (50% humidity). The minimum drying time before proceeding with other work is 6 to 24 hours depending on environmental conditions.

One kilogram (or liter) typically covers 8-10 square meters per coat, depending on the substrate's porosity. We recommend applying at least two coats for maximum protection.

Integration & Storage

Yes, it is highly recommended to use SG211 as a deeply penetrating base sealer, followed by SG918 for decorative surfaces or SG368 for enhanced anti-corrosive protection on adjacent structures.

Store in a cool, dry place away from direct sunlight. The shelf life is 12 months from the date of production.
