KingFloor C500®
Industrial grade floor topping.
SpecWorld has the Spec Pack, CSI specification and drawings for registered specifiers.
- Bond strength to concrete
- > 1.5 MPa
- Vicat setting time
- 1.5 hr @20°C
Overview
KingFloor C500 is designed as an industrial grade floor topping for upgrading and renovating new and existing internal floors. KingFloor C500 is supplied as a pre-blended dry powder designed for application between 5 - 15 mm (in one application) to provide a finished industrial floor.
Where to use
Suitable for use in a wide range of industrial environments subjected to medium to heavy traffic such as:
- Warehouses.
- Food processing plants.
Why use it
- Self-smoothing.
- Dimensionally stable.
- Fast drying.
- Can be pumped to cover an area of 2000 m² per day. Alternatively a coverage of 600 m² per day can be achieved when hand applied, depending on manpower and equipment used.

How to use
Surface preparation
Concrete surfaces must be sound, dry and fully cured (not subject to shrinkage). Any laitance or surface treatments must be removed by mechanical means such as grit blasting. The surface tensile strength of the substrate should be a minimum of 1.5 N/ mm². When applied over KingFloor Base, SHOT BLASTING should be used to remove any laitance followed by vacuuming and priming with KingFloor Primer. If an impervious coating, screed or floor covering is to be used the concrete substrate should be below 75% RH alternatively KingFloor DPM should be applied.
The temperature of the floor must be maintained above 10°C throughout the application and drying of the KingFloor C500.
Priming
For application over cement screeds, KingFloor Base, or porous substrates, seal the prepared surface by applying two coats of KingFloor Acrylic Primer diluted with 3 parts of potable water to one part primer and allow to dry. The primer must be allowed to dry before the application of KingFloor C500.
Mixing
Hand Application
Use a power-whisk fitted in a heavy-duty slow speed electric drill. Mix in the proportion of 25 kg of powder to 4.75 – 5.25 liters of potable water. Pour the water into a suitably sized bucket and gradually add the powder while stirring, until a smooth, lump free consistency is achieved.
Pump Application
Mix the powder and water according to the method recommended by the pump manufacturers. In the case of pumps having a continuous water feed adjust the rate of water flow until the mix is a smooth fluid, uniform grey liquid with no surface separation, producing a flow of approximately 160 mm using a 50 cc flow ring.
Application
Pour or pump the mixed material onto the prepared surface and allow to attain a smooth finish. The use of a spiked roller will help eliminate entrapped air and smooth out flow lines. Apply at a thickness between of 5 - 15 mm in one pass only. It is always better to work in manageable sections of approximately 20m². It is recommended to seal KingFloor C500 with suitable epoxy resin or solvent based acrylic resin sealer, especially when water may come into direct contact with the cured KingKrete base.
Curing
Curing is not required in normal conditions, but in harsh climatic conditions like direct sunlight, flow of wind, elevated temperatures, etc; freshly hardened concrete surfaces should be cured with damp Hessian or to be covered with polyethylene sheets.
Cleaning
Tools and equipment can be cleaned with water immediately after use.
Limitations and notes
Don’t place when the substrate temperature is below 10°C or when the ambient temperature is 10°C and falling.
Protect from frost.
Don’t exceed the recommended water content and only use potable water.
This product is not recommended for external use or situations where water may come into direct contact with the cured material.
For hot climate conditions (temperature > 35°C), special procedures should be conducted.
The material should not be used on floors where rising damp is valid, unless a suitable primer is used.
