Product Overview;

The Everbuild 403 Concrete Hardener and Dustproofer (4 x 25 Litre Pallet Deal) is a professional-grade, high-performance solution developed to strengthen, seal, and dustproof concrete. Formulated for trade use, this penetrating treatment is designed to harden the surface layer of concrete, reducing dust formation while improving durability and wear resistance.

Ideal for industrial, commercial, and residential applications, Everbuild 403 provides a cost-effective method to enhance the strength and longevity of both new and existing concrete floors. This Trade Pallet Money Saver Deal includes four 25-litre drums, offering outstanding coverage and unbeatable value for contractors and large-scale flooring projects.

The Everbuild 403 formula penetrates deeply into the concrete matrix, reacting with free lime to form a dense, dust-free surface that resists abrasion, impact, and weathering. Whether used in warehouses, workshops, or driveways, this hardener and dustproofer delivers long-lasting results you can rely on.

Key Features and Benefits

• Trade Pallet Value: Includes 4 x 25-litre drums—ideal for large jobs or multiple sites.

• Strengthens Concrete: Reacts chemically within the surface to increase hardness and resistance to wear.

• Dustproofing Protection: Seals concrete pores, preventing dusting and creating a cleaner, safer work environment.

• Durable Performance: Extends the lifespan of concrete by reducing erosion and surface damage.

• High Coverage: One drum can cover 100–150m² depending on surface porosity.

• Versatile Application: Suitable for both indoor and outdoor use on new or old concrete surfaces.

• Natural Finish: Retains the original appearance of the concrete, with a light satin effect once cured.

• Professional Grade: Manufactured by Everbuild (Sika), trusted by trade professionals for performance and reliability.

Applications

• Warehouses and Factories: Strengthen high-traffic floors exposed to forklifts and heavy machinery.

• Garages and Workshops: Provides a durable, dust-free surface resistant to oil and mechanical wear.

• Commercial Buildings: Suitable for car parks, loading bays, and production floors.

• Residential Projects: Ideal for driveways, basements, patios, and pathways.

• Maintenance and Restoration: Restores and extends the life of ageing concrete surfaces.

How It Works
Everbuild 403 penetrates deep into porous concrete and chemically reacts with free lime and calcium hydroxide. This reaction forms insoluble crystals, which harden and seal the surface internally—transforming it into a dust-free, wear-resistant finish.

Unlike surface coatings that can peel or flake, Everbuild 403 bonds within the concrete structure, delivering long-lasting protection without changing the surface appearance.
