Everbuild 403 Concrete Hardener & Dustproofer 5L is a concentrated silicate solution formulated to harden and dustproof both new and old concrete surfaces. It chemically reacts with the free lime in cement to form a durable, wear-resistant surface that resists dusting, bloom, and efflorescence. Suitable for internal and external use, it dries clear and is easy to apply by brush or spray. Ideal for garages, workshops, factories, and domestic floors, it improves surface integrity and reduces maintenance

Coverage: approx. 5m² per litre per coat. Apply two coats for best results, followed by a water rinse to remove unreacted material.
