Practical Applications

The Sika Block Paving sealer is suited for a variety of uses, including:

• Protecting block-paved driveways and paths from wear and tear.
• Enhancing natural stone patios by preserving their original appearance.
• Sealing cement-based flagstones to provide a clean and polished finish.
• Stabilising joint sand in high-traffic areas to prevent displacement.
• Offering a weatherproof barrier for outdoor paving projects.

How This Fits Into a Typical Job

This sealer is used after surface preparation is complete. Once the paving is clean, dry, and joints are filled with compacted kiln-dried sand, the product is applied as a protective coating. It forms part of the finishing stage, creating a barrier before the area is exposed to traffic and weather.

How to Use

1. Surface Preparation:
   • Remove loose material using a brush or vacuum. Ensure the joints are filled with compacted kiln-dried sand.
   • Clean existing surfaces thoroughly by removing oil, grease, diesel stains, and any weeds or algae. Allow the area to dry completely.
2. Application:
   • Stir the product well before use.
   • Apply evenly using a spray, brush, or roller. A roller kit is recommended for optimal coverage.
3. Coating:
   • For best results, apply two coats, allowing a minimum of 3–4 hours of drying time between applications. Depending on the substrate, coverage will vary between 5 and 7 square metres per litre per coat.
4. Curing:
   • Allow the treated area to cure fully before exposing it to traffic or moisture.

Storage and Maintenance Tips

• Store in a cool, dry place, away from direct sunlight, to maintain product quality.
• After use, clean all application tools thoroughly to prevent residue build-up.
• Regularly inspect sealed areas for signs of wear and reapply as necessary to maintain protection.
