Hydro Varnish for Concrete
The Hydro Varnish for Concrete is a water-based varnish specifically designed to protect and enhance concrete surfaces finished with a helicopter trowel.
Ideal for residential or commercial areas, this varnish provides water-repellent protection while highlighting the raw and authentic look of concrete.
Why Choose Hydro Varnish for Concrete?
- • Targeted Protection: Specially formulated for helicopter-finished concrete, protecting against water and stains.
- • Natural Finish: Satin finish preserves the raw and minimalist charm of concrete.
- • Easy Application: Its fluid formula ensures even and quick application.
How to Use
Surface Préparation:
- • Ensure the surface is clean, dry, and free of residual moisture.
- • Concrete must be at least 21 days old.
- • If a curing product was used, remove it with Harmony Decap Cure using a green pad. Wash and rinse with a neutral cleaner.
- • If no curing product is present, clean the concrete with Harmony Neutral Cleaner and a mono-brush to lower the pH, preventing varnish powdering due to high pH levels.
Application:
- Use a microfiber mop or applicator brush.
- Apply a thin, uniform layer until the surface is saturated, at a rate of 1 liter for 10 m².
- Once the first coat is dry to the touch, apply a second coat to enhance protection.
Maintenance Tips
- Clean regularly with pH-neutral products to maintain the varnish's quality.
- Reapply a protective varnish layer every 2 to 3 years as needed.
Technical Specifications

- • pH: 3-4
- • Coverage: 1 L = 10-12 m² in a single coat
