KingDeck HP System®
A hard-wearing polyurethane traffic coating system.
SpecWorld has the Spec Pack, CSI specification and drawings for registered specifiers.
Overview
KingDeck HP System is a hard-wearing, polyurethane coating system primarily designed for use in car parks. It has excellent resistance to abrasion and wear and excellent chemical resistance to petrol, diesel, engine oil, brake fluid and de-icing salts.
The KingDeck HP System consists of the following components:
- KingDeck Primer U: a two component, solvent-free epoxy primer with excellent adhesion to concrete and cementitious substrates.
- Antislip Aggregate #3: a hard-wearing quartz aggregate for producing an anti-slip finish.
- KingDeck Wear Coat TE: a two component, solvent- free, pigmented wearing course with excellent resistance to abrasion and chemical attack.
Where to use
KingDeck HP System is designed for application in different areas of car parks, such as:
- Ramps and turning circles.
- Traffic aisles and parking bays.
- Pedestrian walkways.
Why use it
- Excellent resistance to petrol, diesel, engine oil and brake fluid.
- Resistant to de-icing salts.
- Available in both smooth and aggregate broadcast finishes for different slip resistance requirements.
CHEMICAL RESISTANCE
KingDeck HP provides resistance to a wide range of oils, fuels, solvents, acids and bases commonly encountered in car parks. For detailed information, contact KINGKRETE’s Technical Department.

CAR PARKS DECKS
Substrate Preparation
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, consult with KINGKRETE’s Technical Department.
How to use
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. 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.
KINGDECK PRIMER U
Mixing (KingDeck Primer U)
KingDeck Primer U comprises two components; a resin and hardener which are supplied pre-weighted in the correct proportions. Under no circumstances should part mixing be carried out. Taking care to ensure that the bottom and sides are thoroughly drained, pour the contents of the hardener portion into the resin container.
Using a power whisk attached to a slow speed electric drill, mix for approximately 2 minutes, scrape down and re-mix for a further 1 minute, avoiding the entraining of excessive air, until a uniform consistency is obtained. Allow to stand for 1 minute.
Note: Never mix KingDeck Primer U by hand as this could lead to areas of uncured material.
Application (KingDeck Primer U)
Once mixing is complete, spread the KingDeck Primer U onto the prepared surface by brush or lamb’s wool roller. To obtain an anti-slip finish, whilst KingDeck Primer U is still wet, broadcast with Antislip Aggregate #3 according to the table of the coverage rates and allow to dry. All excess aggregates shall be removed before applying the final top coats.
Overcoating
KingDeck Primer U may be over-coated as soon as it becomes tack free within 24 hours.
KINGDECK WEAR COAT TE
Mixing (KingDeck Wear Coat TE)
KingDeck Wear Coat TE comprises two components, a resin and a hardener, which are supplied pre-weighted in the correct proportions. Under no circumstances should part mixing be carried out.
The contents of the resin pack should be thoroughly stirred to disperse any possible settlement. Taking care to ensure that the bottom and sides are thoroughly scraped, transfer the entire contents of both components into a separate mixing container.
Using a power whisk attached to a slow speed electric drill, mix for approximately 3-5 minutes and until uniform colour and consistency are achieved.
Note: Never mix KingDeck Wear Coat TE by hand as this could lead to areas of uncured material.
Application (KingDeck Wear Coat TE)
Once mixed, the material should be immediately applied, ensuring that a continuous coating is obtained. Application can be done using a brush, roller or an airless spray machine.
Over-coating
KingDeck Wear Coat TE should become tack-free before it is over-coated with a second coat of KingDeck Wear Coat TE. This can be achieved after a minimum 6 - 8 hours from application at 25°C.
Cleaning
Tools should be cleaned with KINGKRETE Solvent immediately after use.
Limitations and notes
- KingDeck HP System should be protected from contact with water for the first 24 hours after application as discoloration could occur.
- For cold weather working (down to 5°C), it is recommended that materials are stored in a heated building and only removed immediately before use. Accelerated heating methods are not to be utilized under any circumstances.
- Application to commence while temperature is 5°C and rising. In hot weather working conditions (35°C) and above, it is recommended to keep material in a cool shaded area to ensure ease of application.
