Qualidur is a dry-shake concrete surface hardener for floors, which contains graded quartz granules, hard-wearing mineral aggregates, cement, pigments and mixing additives. It can be sprinkled as a dry powder to the top of a freshly-poured concrete floor, or pre-mixed with water and manually spread over the slab. Once cured, it becomes monolithic with the slab and provides a durable, colourful flooring surface.
Fibre suppressant for SFRC
Qualidur is often used as a surface fibre suppressant for steel fibre reinforced concrete (SFRC). Adding Qualidur improves the quality and smoothness of the floor’s surface. We particularly recommend a wet-on-wet (fresh-on-fresh) application if Qualidur is being used primarily to suppress fibres, as the thicker topping will provide a better result. Please refer to our FAQ on wet-on-wet application to learn more. Examples of both applications are shown in the videos at the end of this page.
Oil resistant flooring
Qualidur enables the floor to be resistant to oils and hydrocarbons, so it is a good choice where the floor may be at risk of damage from oil or petrol spillages. If you are primarily choosing Qualidur for this reason, we recommend you discuss the application first with our technical advisers.
Long-lasting appearance – no dust, no rust
Because Qualidur contains no metal particles, it requires no special treatment to prevent rusting. It is also easy to clean and resists dust infiltration. With a normal cleaning and maintenance regime, using recommended products, the floor will retain its attractive appearance for years.
Adding colour to concrete floors
Qualidur is available in our full range of standard colours, and we can produce special colours too. Adding Qualidur is an easy and cost-effective way to add long-lasting colour to a concrete floor’s surface, without colouring the concrete or using floor paint.
