KingCoat E300®
High build polyurethane and epoxy floor and wall coating.
SpecWorld has the Spec Pack, CSI specification and drawings for registered specifiers.
Overview
KingCoat E300 is a composite system compose of three layers; epoxy primer, epoxy under coat, and a U.V resistant polyurethane top coat.
KingCoat E300 provide a hard abrasion resistance coating with outstanding chemical resistance suitable for floors, walls, ceiling and other substrates. KingFloor Primer S, 600UC and 600P are supplied as "two component" products in pre-weighed base and hardener packs, ready for site mixing.
Where to use
KingCoat E300 is designed for applications such as:
- Car parks, showrooms and warehouses.
- Heavy duty protective coating for concrete and steel.
- Heavy duty wall and floor coating in food processing plants, grain silos, dairies, breweries, hospitals, and pharmaceutical industries.
- High chemical resistant protective coating for power stations, oil refineries, and sewage treatment plants.
- Production, maintenance and assembly areas.
Why use it
- Excellent UV resistance.
- Excellent resistance to a variety of chemicals.
- Easy to clean with a smooth, hard and glossy finish.
- Exhibits good mechanical properties.
- Resistant to sewage effluents.

How to use
Method of use
Substrate Preparation
Concrete surfaces
The Substrate should be sound, clean and free from
contamination. Surface Laitance should be removed by grit blasting or water jetting. All exposed blow holes should be filled with epoxy paste using KingRep EP10.
Steel surfaces
All surfaces should be grit blasted to reach a bright finish meeting the requirement of Swedish Standard SA 2 1/2.
Priming
Concrete substrates should be primed with KingFloor Primer S. Use lambs wool roller to apply the primer. Work the primer well into the surface of the concrete. KingFloor Primer S should be applied at the rate of 0.25 kg/m² to give a dry film thickness of 125 microns.
KINGCOAT E300UC
Mixing
To ensure proper mixing, a mechanically powered mixer or drill fitted with suitable paddle should be used. Stir the content of each component separately to disperse any settlement. Add the entire content of the hardener to the base and mix for 3 minutes and until uniform color and consistency are achieved.
Application
KingCoat E300 UC can be applied by brush; roller or airless spray machine. The first coat should be applied to obtain a continuous uniform coating. The second coat should be applied within the over coating time to achieve the maximum adhesion between the two coats.
Two coats of KingCoat E300UC should give 400 micron dry film thickness.
KingCoat E300P should be applied over the applied KingCoat E300UC within 24 hours, otherwise a light abrasion should be conducted on the dried KingCoat E300UC and cleaned thoroughly before applying KingCoat E300P.
KINGCOAT E300P
Mixing
To ensure proper mixing, a mechanically powered mixer or drill fitted with suitable paddle should be used. Stir the content of each component separately to disperse any settlement. Add the entire content of the hardener to the base and mix for 3 minutes and until uniform color and consistency are achieved.
Application
KingCoat E300P is used as a top and UV resistant coat. KingCoat E300P can be applied by brush, roller or airless spray. KingCoat E300P should be applied at the rate of 0.145 kg/m² to obtain a continuous uniform coating of a dry film thickness of 75 micron.
Cleaning
All tools should be cleaned immediately after application using KINGKRETE Solvent. Hardened materials must be cleaned mechanically.
Coverage, packaging and storage
Coverage
KingFloor Primer S: 0.20 kg/m2 to achieve 125 micron dry film thickness.
KingCoat E300UC: 0.33kg/m²/coat to achieve 200 micron dry film thickness. (Two coats required to achieve 400 micron).
KingCoat E300P: 0.145 kg/m²/coat to achieve 75 micron dry film thickness.
Total system dry film thickness = 600 microns.
Packaging
