Overview
KingFloor C400 is designed as an industrial grade floor topping for upgrading and renovating new and existing internal floors.
KingFloor C400 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.

Acid etching can be used after consulting with KINGKRETE's Technical Department.
Surface defects such as voids and blowholes should be repaired before application. Consult KINGKRETE's Technical Department for the best repair material.
Surfaces must be free of any dust or loose particles before product application. Use suitable methods like vacuuming or sweeping.
If possible, apply the product on a small test area before actual application to check for any problems with the surface preparation.
How to use
Substrate preparation
Concrete substrates should be fully cured and achieve a minimum compressive strength of 25 N/mm2 and a minimum pull-off strength of 1.5 N/mm2. The concrete substrate should be below 75% RH and have less than 4% moisture content. Alternatively, KingFloor DPM should be applied according to the priming section.
Surface preparation
Concrete surfaces must be degreased using degreasing products, torching or any other suitable method which assures the surface is free from any oil traces. Surfaces should be sound and with no irregularities as they can affect the finish of the applied product.
Concrete surfaces are to be mechanically prepared to remove laitance and achieve a flat surface, grit blasting or surface profiling equipment are preferred.
Priming
Priming is done to seal the substrate in order to prevent pin holing caused by the release of air from the substrate. The following priming options are available:
KingFloor Primer C
For application onto sand/cement screeds, concrete and other porous substrates, first seal the prepared surface by applying one coat of KingFloor Primer C diluted with 3 parts potable water and allow to dry.
Prime the sealed surface by applying a second coat of KingFloor Primer C diluted with 3 parts potable water and brush well into the surface. The primer must be allowed to dry before the application of KingFloor C400.
KingFloor Primer
For impervious surfaces, apply one coat of KingFloor Primer and whilst still tacky fully blind with Antislip Aggregate #2 at approximately 3 kg/m2 until the surface is covered and no resin spots remain. Allow to dry fully overnight and remove excess aggregate before applying KingFloor C400.
For porous substrates, apply one coat of KingFloor Primer and allow to cure. Apply second coat and whilst still tacky fully blind with Antislip Aggregate #2 in the manner mentioned above.
KingFloor DPM
For surfaces with RH between 75 and 85%, prime with 1 coat of KingFloor DPM and allow to dry prior to application of KingFloor Primer. For surfaces with RH greater than 86%, prime with 2 coats of KingFloor DPM and allow the second coat to dry before priming with KingFloor Primer.
After KingFloor DPM has been applied and left to cure, apply KingFloor Primer and whilst it is still tacky fully blind with Antislip Aggregate #2 at approximately 3 kg/m2, until the surface is covered and no resin spots remain. Allow to dry fully overnight and remove excess aggregate before applying KingFloor C400.
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 litre 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.
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 5°C or when the ambient temperature is 5°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.

Health and safety
As with all chemical products, care should be taken during use and storage to avoid contact with eyes, mouth, skin and foodstuffs. Treat splashes to eyes and skin immediately. If accidentally ingested, seek medical attention. Reseal containers after use. Use in well ventilated areas and avoid inhalation.
