When to choose this product
For concrete and masonry exposed to water and de-icing salts. A penetrating silane/siloxane treatment that reduces moisture and chloride ingress on horizontal and vertical surfaces.
Product advantages
- A ready-to-use water-based, silane/siloxane water repellent and “chloride screen” for the protection of concrete and masonry.
- An easy to apply treatment penetrates more deeply than conventional water or solvent-based water repellents.
- Protects horizontal and vertical surfaces from moisture intrusion and chemical attack of chloride salts.
More advantages
- Provides excellent protection for retaining walls, bridge pilings and other vertical areas exposed to de-icing salts.
- In coastal areas, it protects against salt air by screening chlorides from penetrating through concrete to the reinforcing steel.
- Reduces rebar corrosion and surface spalling caused by water-carried 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 temperature4–32 °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.
Touch-dry in about 1 hour. Protect from rain for at least 6 hours and traffic for 24 hours. Water repellency develops over several days. Clean equipment with warm soapy water.
Storage and handling
Storage temperature7–38 °C
Store upright in sealed original containers in a cool, dry place. Close after dispensing. Follow local rules for unused product and packaging.
Protect from freezing.
