Overview
KingSeal C50 is a two component polymer modified cementitious tough sealant suitable for sealing joints and cracks in concrete, pre-cast elements, mortars and bricks.
Where to use
KingSeal C50 is ideally designed for use in the following applications:
- Sealing all types of cracks in concrete and masonary.
- Sealing joints with anticipated movement up to 5%.
- Sealing joints between pre-cast elements for both horizontal and vertical application.
- Sealing joints in water retaining structure.
Why use it
- Excellent slump resistant up to 3 cm wide on vertical surfaces.
- Weather resistance.
- Can accomodate movement up to 5%.
- Can be over painted.
- Non-toxic, suitable for use inside potable water tanks.
- Bonds to damp concrete.
- Good impact and tear resistant sealant.

The full powder bag is then added slowly to liquid while mixing continuously with low speed mixer/drill (400 - 600 rpm). Mixing time should be continued for 3 minutes until a uniform consistency is obtained.
PLACING AND FINISHING
The mixed mortar shall be applied directly into the damped joints by trowel or putty knife and smoothed to the disred finish.
To enhance bonding of mortar to joint sides, the white liquid polymer can be applied by brush on the joint edges and while still tacky the mixed KingSeal C50 is applied.
JOINT SIZE SUITABILITY
Joint width:
- 3 mm minimum.
- 30 mm maximum.
Joint depth:
- 3 mm minimum.
- 15 mm maximum.
How to use
Joint preparation
- The joint surfaces must be clean, free from contamination and curing compound.
Priming
Prior to applying KingSeal C50, all joints must be dampened with water till a surface saturation dry condition is reached. All excess water should be removed prior to KingSeal C50 application.
Yet to improve bonding, the white liquid polymer can be applied by brush on joint edges, and while still tacky, the mixed KingSeal C50 is applied.
Mixing
To ensure proper mixing, a mechanically powered mixer or drill fitted with suitable paddle should be used.The white liquid should be added to a clean container.
Curing
Curing time varies depending on ambient temperature and relative humidity but normally 7 days should be enough. If KingSeal C50 is subjected to water submersion, then allow for 2 - 3 weeks of curing time.
Notes: KingSeal C50 should not be applied to frozen substrates or if ambient temperature is expected to fall below 5°C.
Cleaning
All tools should be cleaned immediately after finishing with water. Hardened materials can be cleaned mechanically.
