Overview
KingCoat PU is a high quality UV resistant polyurethane coating. It is supplied as one component product ready for use. KingCoat PU can be applied externally and internally to concrete and asphalt surfaces. KingCoat PU will provide maximum protection to a variety of surfaces exposed to aggressive environments as in light industrial areas.
Where to use
KingCoat PU is designed for external and internal
application areas such as:
- Roads, motor ways and run ways.
- Car parks, playground and tennis court topping.
- Concrete surfaces, asphalt and tarmac.
Why use it
- Highly durable and tough wearing marking paint.
- Quick drying easy to apply (one component).
- High opacity and available in different colours.
- Excellent adhesion to all types of new (28 days) and old concrete.

How to use
Method of use
Substrate Preparation
Concrete surfaces
The Substrate should be dry, 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 20.
Steel surfaces
All surfaces should be grit blasted to reach a bright finish meeting the requirement of Swedish Standard SA 2 1/2 before applying the KingCoat PU Primer.
KingCoat PU Primer
is a 2 packs anti-corrosion primer system is used to treat ready steel surfaces. Touch dry of the primer is 2 hours @ 25°C and over coating time internal is minimum 16 hours.
Application
KingCoat PU 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 (if needed) should be applied after the overcoating time to achieve the maximum adhesion between the two coats.
REMARKS
- If surfaces are subjected to moisture or rising damp, like basements or ground level floors, a water proofing membrane should be included to avoid possible blistering or flaking of the coating.
- For asphalt and similar surfaces, new asphalt must be aged at least 28 days before coating.
- Better not to apply the material if substrate temperature above 40°C.
Cleaning
All tools should be cleaned immediately after application using KINGKRETE Solvent. Hardened materials must be cleaned mechanically.
Coverage, packaging and storage
Coverage
KingCoat PU approximately 6 - 7 m²/ltr per 100 microns coat.
KingCoat PU Primer 7 - 10 m²/ltr to give 40 - 70 microns dry film thickness.
Packaging
KingCoat PU is available in 5 litre packs and 18 litre packs.
KingCoat PU Primer is available in 5 kg packs (3.45 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.
