KingCoat HD500®
Two-component, low-solvent, heavy-duty epoxy protective coating for steel and concrete.
SpecWorld has the Spec Pack, CSI specification and drawings for registered specifiers.
Overview
KingCoat HD500 is a resistant, two-component, low-solvent epoxy coating with mineral fillers. After full cure it forms a tough, hard and heavy-duty protective coating for concrete and steel, and is suitable for buried and submerged structures, hydraulic-engineering constructions and the internal lining of tanks and reservoirs, such as those used in sewage treatment and the agricultural and chemical industries. It is also suitable where application onto damp concrete is unavoidable.
Where to use
- Protective coating for concrete and steel
- Buried and submerged structures
- Hydraulic-engineering constructions
- Internal lining of tanks and reservoirs (sewage treatment, agricultural and chemical industries)
- Surfaces where application onto damp concrete is inevitable
KingCoat HD500 is not suitable for surfaces in contact with drinking water and must be applied only by experienced professionals.
Why use it
- Tough, hard and heavy-duty
- Abrasion and impact resistant
- Resistant to water and to a wide range of chemicals
- Low solvent content
- Can be applied onto damp concrete

Chemical resistance
KingCoat HD500 is resistant to fresh water, process water, brackish water, seawater, domestic sewage, dilute inorganic acids and alkalis, neutral salts, mineral and fuel oils, grease and detergents. Industrial wastewater resistance is available on request, based on wastewater analysis. It is not resistant to benzene-hydrocarbons and tar oil.
How to use
Method of use
Surface Preparation
Concrete must be solid with a gripping surface, free of cement laitance, dust, loose and friable particles and other contamination, with a moisture content not exceeding 6%. Sweep blasting increases adhesion and is particularly important for underwater exposure. Steel must be prepared to the appropriate cleanliness standard before coating.
Mixing
Stir component A thoroughly with an electric mixer (starting slowly, then increasing to approximately 300 rpm). Add component B carefully and mix both components thoroughly, including the sides and bottom of the container, for at least 3 minutes until homogeneous. Transfer the mixed material to a clean container and mix again briefly.
Application
Airless spray gives the best results and readily achieves the specified dry film thickness (efficient equipment, minimum pressure 180 bar, nozzle ≥ 0.38 mm, material temperature minimum 15°C). Where applied by roller or brush, additional coats may be required to reach the specified thickness. On concrete, apply 2 – 3 coats, thinning the first coat with a maximum of 5% of a suitable KingKrete epoxy thinner and applying subsequent coats unthinned. On steel, apply 2 – 3 coats, preferably in alternating shades to indicate wear and the need for re-application.
Cleaning
Clean all tools with a suitable KingKrete epoxy thinner immediately after use. Cured material can only be removed mechanically.
Coverage, packaging and storage
Packaging
