This solvent-based water-repellent sealer protects masonry surfaces from dampness, rain, and frost damage while maintaining their natural appearance.

Who This Product Is For

This treatment is for property owners, builders, and maintenance professionals working with masonry structures. It suits those seeking to protect exterior walls and surfaces from weather-related deterioration.

The product addresses requirements for residential buildings, commercial properties, and outdoor masonry features that need long-term water protection without altering visual characteristics.

Key Features

• High Penetration Depth: The solution absorbs up to 5mm into surfaces, providing defence against moisture.
• Breathable Protection: Allows walls to breathe while safeguarding against rainwater intrusion.
• Frost Resistance: Reduces the risk of efflorescence and surface spalling caused by freezing and thawing cycles.
• Clear Finish: Retains the original look of brick, stone, or concrete without altering their aesthetic.
• Long-Lasting Effectiveness: Protects treated areas for up to a decade, even in harsh weather conditions.

Key Benefits

• Prevents damp-related issues, safeguarding homes and buildings from potential damage.
• Maintains the thermal efficiency of walls by reducing moisture absorption.
• Extends the life of masonry surfaces with durable, low-maintenance protection.
• Provides reliable protection with a long-lasting solution for exterior surfaces.

Practical Applications

The Sika Water Seal is suitable for use on exposed masonry surfaces requiring protection against moisture. Its versatility makes it appropriate for:

• Shielding brick façades from rainwater damage.
• Protecting stone and concrete surfaces from frost-induced cracks.
• Enhancing the durability of outdoor structures like retaining walls or garden features.
• Preserving the heat-insulating properties of external walls in colder climates.

How This Fits Into a Typical Job

This water repellent is applied during the finishing stage of masonry work or as part of maintenance programmes. After surfaces are cleaned and prepared, the treatment is brushed or sprayed onto dry masonry to create a protective barrier.

The product functions as a preventative measure, forming an invisible shield that allows the wall to breathe while repelling water. It is typically applied before potential weather exposure and maintained periodically based on surface condition observations.

How to Use

1. Surface Preparation:
   • Clean the area thoroughly, making sure it is dry and free of dirt, dust, and contaminants. Remove any loose material or debris for optimal adhesion.
2. Stirring:
   • Mix the product well before application to achieve consistent results.
3. Application:
   • Apply using a brush or low-pressure spray, so the surface is saturated. Allow the liquid to run down approximately 300mm for complete coverage.
4. Drying Time:
   • Let the treatment dry under well-ventilated conditions. Avoid applying in wet or humid weather.
5. Maintenance:
   • Reapply when the surface begins to show signs of reduced water repellency.

Not Suitable For

• Interior surfaces or areas with constant water immersion
• Surfaces that require a coloured or opaque finish
• Applications on non-porous materials like metals or plastics
• Use in confined spaces without adequate ventilation

Storage and Maintenance Tips

• Store the container in a cool, dry place away from direct sunlight.
• Make sure the lid is tightly sealed after use to prevent evaporation or contamination.
• Clean tools immediately after application to avoid product build-up.
