KingSure®
Hot applied rubberized asphalt waterproofing membrane
SpecWorld has the Spec Pack, CSI specification and drawings for registered specifiers.
Overview
KingSure is a hot-applied rubberised asphalt waterproofing membrane that cools down to form a flexible, strong, fully adhered and monolithic waterproofing membrane with extremely high durability and resilience.
Where to use
KingSure provides the perfect waterproofing membrane for the following applications:
- Roofs.
- Bridge decks and tunnels.
- Foundation and basement walls.
- Green roofs and planters.
- Plaza decks.
Why use it
- Self-healing properties for minor punctures.
- Fully bonded to the substrate eliminating any water migration beneath the membrane.
- Thick monolithic (joint-free) waterproofing membrane.
- Highly resistant to fertilisers, acids and numerous waste chemicals.
- Tough and flexible.
- Can be applied even if the substrate contains little irregularities or has hard to reach areas.
Technical properties
Standards and approvals
KingSure was tested in accordance with CAN/CGSB- 37.50.
How to use
Method of use
Substrate Preparation
Substrate should be free from laitance or any contamination such as oil, grease, dirt or traces of surface treatment products and release agents.
Concrete substrates should be cured a minimum of 14 days. Depending on conditions (i.e., ambient temperature, humidity) the concrete may be dry enough to receive application of the membrane in less than the 14 day minimum recommendation.
SURFACE CONDITIONING
- For concrete substrates, apply KingProof B100 as a surface conditioner at a rate of 5 m²/ltr. Do not dilute KingProof B100 with water before application.
- Wood, plywood, metal or gypsum board substrates do not need to be primed.

Application
Melt KingSure in a double-jacketed melter at a temperature between 175°C and 200°C while mixing continuously.
Apply the first coat of KingSure at 2.0 mm thickness, then apply the fabric-reinforcing sheet KingFlash H by firmly embedding it into the hot layer of KingSure. Apply the second coat of KingSure at a thickness of 3.0 mm.
Cover KingSure membrane with a 2 mm thick KingFlex rubberised sheet reinforced with fibres, overlapping adjoining edges by 60 mm.
Cleaning
All equipment should be cleaned immediately after finishing using xylene, acetone or other suitable solvents.
Coverage, packaging and storage
Coverage
Approximately 1.15 kg/m² per mm layer thickness.
Packaging
KingSure is packaged in 15 kg blocks, one block per carton.
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.
