Who This Product Is For

This product suits professional landscapers, paving contractors, and property maintenance teams who work with block paving installations. It is also appropriate for homeowners seeking to maintain and protect their paved areas.

The sealer is designed for use on residential driveways, commercial pathways, patios, and other paved surfaces that require protection from weathering and stabilisation of jointing sand.

Key Features

• Application Methods: Suitable for use with brushes, rollers, or sprayers for added convenience.

Practical Applications

Its reliable formula ensures effective performance across a range of outdoor surfaces, keeping them in top condition.

How This Fits Into a Typical Job

This sealer is applied as the final protective coating after block paving installation or cleaning. It follows surface preparation and joint filling with kiln-dried sand, forming the last step in the paving maintenance process.

The product creates a protective barrier that seals the surface and stabilises the jointing sand, preventing weed growth and reducing ongoing maintenance requirements for the paved area.

How to Use

1. Preparation:
   • Remove all loose material from the surface using a brush or vacuum.
   • For existing installations, make sure joints are filled with kiln-dried sand and remove oil, grease, or diesel stains.
   • Treat weeds, algae, or moss with a suitable cleaning product, and make sure the area is completely dry before application.
2. Application:
   • Stir thoroughly before use. Apply with a brush, roller, or spray for even coverage.
   • Two coats are recommended for optimal results, allowing a minimum of 3-4 hours between coats.
3. Curing:
   • Allow the product to cure fully through solvent evaporation, forming a long-lasting protective layer.

Storage and Maintenance Tips

• Keep the product in a cool, dry place to maintain its quality.
