When to choose this product
An additive for C² Hard or C² Super Hard, for horizontal and vertical concrete exposed to moisture and chloride salts. Adds water repellency and chloride protection to the hardening treatment.
Product advantages
- A pre-measured additive specially formulated to mix with C² Hard or C² Super Hard.
- The prepared mixture hardens, reduces dusting and protects against abrasion, moisture intrusion and chloride salts.
- The treatment penetrates the concrete to provide protection beneath the surface.
More advantages
- Protects horizontal and vertical concrete surfaces against moisture intrusion and the chemical action of chloride salts.
- Protects against de-icing salts and salt air while allowing moisture vapor to escape. Suitable for horizontal and vertical concrete; the water-based formula has low odor.

Preparation and working conditions
Surface and air temperature4–35 °C
Remove dirt, grease, curing residues and coatings that block absorption. Leave the concrete clean, dry and absorbent; check uniform wetting with a light water spray.
Maintain the stated air and surface temperatures during application and for 8 hours afterwards.
Equipment
Use a low-pressure sprayer. Distribute evenly without puddles; avoid forming a fine mist.
Practical advice
Test a representative area with the equipment and preparation planned for the job. Let it dry before assessing the result and coverage.
Use the prepared mixture within 24 hours.
Touch-dry in about 1 hour. Protect from rain for at least 6 hours and traffic for 24 hours. Water repellency continues to develop for up to 14 days.
Clean tools with fresh water before the product dries. Immediately wash splashes off glass, aluminium and other adjacent surfaces.
