Frequently Asked Questions (FAQ)
What is a surface passivator and how does it work?
A surface passivator is a specialized surface treatment agent designed for concrete. It delays the setting process of the surface cement paste to a specific depth, allowing the outer layer to be washed away easily to expose the aggregate beneath for decorative flooring and walls.
How do I choose the correct model for my project?
The model choice depends on your required aggregate exposure depth: Model 0.5 (0.5mm) is for washing sand floor; Model 1.0 (1mm) is for washed sand (glass sand) and small gravel; Model 2.0 (2mm) is for medium gravel flooring; and Model 3.0 (3mm) is best for washed stone walls and floors.
Can this product be applied in extreme weather conditions?
Yes, our surface passivator is formulated to maintain stability and performance during construction under both high and low temperature conditions.
Is this product environmentally safe and VOC compliant?
Absolutely. The product is water-soluble, solvent-free, and contains 0 VOC content, making it fully compliant with strict environmental volatile standards.
How does it protect freshly poured concrete from rain?
Upon application, it forms a rapid-drying polymer film over the concrete surface. This film reduces moisture loss and shields the fresh concrete from potential rainwater erosion.
What are the storage requirements and shelf life?
The product has a shelf life of 12 months. It should be stored in its original sealed container in a cool, dry place, ensuring it is kept above freezing temperatures (32°F / 0°C).
