Sika Dustproofer & Concrete Hardener 5L (879841)

Sika Dustproofer & Concrete Hardener 5L

MPN: 879841 | Barcode: 5029347004354

This 5L format is designed for treating larger concrete areas, helping to reduce surface dusting while improving durability and wear resistance. It penetrates into the substrate to strengthen the surface, making it suitable for both new and existing concrete in high-traffic environments.

Key Performance Benefits

• Reduces Dusting: Helps minimise loose surface dust on concrete floors.
• Surface Hardening: Strengthens the top layer to improve resistance to wear and abrasion.
• Improved Durability: Supports longer-lasting concrete surfaces in demanding conditions.
• Clear Finish: Maintains the natural appearance of the surface with a slight sheen.

Typical Applications

• Warehouses, factories, and industrial floors.
• Garages, workshops, and service areas.
• Basements, storage areas, and utility spaces.
• External concrete surfaces requiring reduced dusting.

Quick Application Guide

Ensure the surface is clean, sound, and free from dust, grease, and loose material before application.

• Application: Apply evenly by brush, roller, or sprayer.
• Absorption: Allow the product to soak into the surface for consistent coverage.
• Drying: Allow to cure fully before use (typically 24–48 hours depending on conditions).
• Aftercare: Rinse the surface with clean water after curing to remove any unreacted material.

Helpful Tools

For even coverage across larger areas, use a roller kit or a 5L pressure sprayer to ensure consistent application.

This penetrating treatment is widely used to improve the performance and lifespan of concrete floors, particularly in environments where dusting and surface wear are common issues.
