Resists erosion due to heavy
vehicular or traffic movement
Low water absorption
Ideal for interior and exterior application
Non oxidising, hence no corrosion or erosion
Forms monolithic bonds with base concrete
Duraflor is a high-quality durable cementitious-based, non-metallic, non-oxidising concrete floor hardener free from organic impurities. This hard-wearing dry shake powder is a well-manufactured, graded composition of selected cement, additives, graded aggregates & polymers to ensure ease of placing and finishing. This is best suited for residential, commercial and industrial floors to deliver a monolithic and high abrasion-resistant floor. The finished surface with floor hardener provides better impact resistance and also protects the surface from gas, oil and chemical attack owing to its non-skid, anti-slip properties.
Floor Hardener is spread on the concrete surface to improve their resistance to abrasion and inhibit dust formation. Floor hardener is suitable for all floor exposed to severe mechanical wear for e.g., Ware house, Quays, Car-parks, Service station, Traffic lanes, Toll areas, Engineering workshops, Garage, Ramps
If the concrete floor is being used in an industrial setting or warehouse building, or even a heavy traffic retail environment, a hardener is recommended. When flooring works hard, there is a substantial risk of damage due to abrasion between tyre and concrete surface which results in severe dust generation and cavity formation on concrete surface. Further the cavity area and depth increases as there will be continuous impact on the edges of cavities. In order to reduce the abrasion, floor hardener is used on top layer of the concrete which makes a monolithic bond with base concrete and hence surface becomes thin, smooth, hard, durable, highly abrasive and impact resistant.
The base concrete should have a minimum cement content of 300 Kg/m3. The concrete mix should be designed to minimum segregation and bleeding. Free water: cement ratio is less than 0.55 is appropriate. The slump of the concrete should be between 70 to 100mm.
Vacuum dewatering is not recommended when W/C ratio of less than 0.55 has been used. The base concrete should be laid and compacted in accordance with good concreting practices. Accurate finished profile and minimum laitance build up should be ensured.
Appropriate timing for floor hardener application over green concrete is critical. Application must start when the base green concrete has to the point when light foot traffic leaves an imprint of about 3mm. Subsequently, any bleed water must be evaporated. Application must be done in 2-3 slots spreading or broadcasting the hardener onto the concrete. The concrete will turn uniformly grey as floor hardener absorbs moisture from concrete, then apply trowel or wooden floater. The first and second broadcasting will lead to some bleed water, you can then spread the material to ensure complete elimination of bleed water during the final broadcasting. Power floater can be applied for larger areas. It is important to ensure that the surface is not being over-worked.
