KingFloor EP25®
Solvent based epoxy resin floor and wall coating.
SpecWorld has the Spec Pack, CSI specification and drawings for registered specifiers.
Overview
KingFloor EP25 is a hard wearing, solvent based, epoxy resin coating, designed to provide a hard, semi-gloss coating to concrete floors, walls, ceiling, steel and other substrates.
Moreover, KingFloor EP25 can be used as a primer for solvent based and solvent-free high build epoxy coatings.
Where to use
KingFloor EP25 is used as protective, decorative and hard wearing coating for floors or walls in many applications including:
- Soft drink and beverage production areas.
- Dairies production areas.
- Show rooms.
- Industrial and commercial kitchen walls.
- Warehouses.
- Hospitals and pharmaceutical factory walls.
- Fish and meat processing plant walls.
- General food processing and manufacturing plants.
- Light vehicular traffic areas.
Also KingFloor EP25 can be used as a primer for solvent based and solvent-free high build epoxy coatings.
Why use it
- Can be used on concrete, steel, galvanized steel substrates.
- Excellent chemical and mechanical resistance.
- Available in a wide range of attractive colours.
- Cost effective.
- Easy application.
- Produces a seamless semi-gloss surface that is both easy to clean and does not induce bacterial and fungal growth.

How to use
Substrate preparation
The substrate must be clean, dry, even, dense and free from oil, grease, dust and other contaminants. A clean surface will ensure maximum adhesion between the substrate and the coating.
Concrete floors must have a minimum compressive strength of 25 N/mm² and a maximum concrete relative humidity of 80% (max. moisture content of 4%), relative humidity can be measured by using hygrometers. Concrete relative humidity should be less than 80% for concrete of 28 days old or more.
Surface preparation
Unsound layers and contaminated concrete surfaces must be prepared using mechanical surface removing equipment.
Acid etching can be used only in well ventilated areas. Areas deeply contaminated by oil or grease, such areas should be treated by hot compressed air.
Mixing
To avoid inconsistent workability and pot life, make sure that the materials to be used are stored in shaded area and protected from extremes of temperatures, for at least 24 hours prior to application. Prior to mixing, stir individual components of the Base and Hardener.
Add the entire content of the hardener container to the base and mix thoroughly for at least 3 minutes.
Note: In certain cases the Base of the product can be supplied uncoloured and needs the addition of a colour pack. In such cases, mix the components of the colour pack and Base for 2 minutes, then add the entire content of the Hardener to the mixture and mix thoroughly for 3 minutes.
COATING
Use brush or lambs wool roller, or airless spray machine to apply the mixed KingFloor EP25 onto the prepared surfaces.
Apply 2 coats of KingFloor EP25 at 5.5 - 6.5 m²/kg/coat, second coat should be applied at a right angle to the first coat.

The second coat may be applied as soon as the first coat has initially dried. Drying time will depend on the substrate and the ambient conditions. If the over coating time is exceeded the first coat must be abraded with sand paper prior to the application of the second coat. Adequate ventilation must be provided to ensure that necessary drying and curing of the material is achieved.
REMARKS
- Higher traffic areas should receive extra coats or a higher build system.
- KingFloor EP25 should not be applied at temperatures below 10°C or where ambient relative humidity exceeds 85%.
- KingFloor EP25 should not be applied onto surfaces known to suffer from rising dampness.
- In case of spray applications, airless spray machines should be used.
Cleaning
Tools and equipment can be cleaned with KINGKRETE Solvent. Dried KingFloor EP25 may be removed mechanically.
Coverage, packaging and storage
Coverage
The coverage rate is 30 m²/5 kg pack per coat to achieve dry film thickness of 70 - 80 microns per coat. When used as a primer apply KingFloor EP25 in one coat at a rate of 25m²/5 kg achieving a thickness of around 90 microns.
Packaging
KingFloor EP25 is available in 5 kg packs (3.85 litre) and 20 kg packs (15.4 litre).
Storage
Shelf life is 1 year when stored under cover, out of direct sunlight and protected from extremes of temperature. Failure to comply with the recommended storage conditions may result in premature deterioration of the product or packaging. For specific storage advice consult KingKrete's Technical Services Department.
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.
