KingAdd 50WP®
High performance permeability and absorption reducing admixture.
SpecWorld has the Spec Pack, CSI specification and drawings for registered specifiers.
Overview
KingAdd 50WP is a liquid concrete admixture formulated from selected organic materials specially designed to produce hydrophobic properties when mixed with concrete. These hydrophobic materials will repel external water and reduce the permeability of concrete.
Where to use
KingAdd 50WP in combination with KingAdd 52WP or other high performance super plasticiser from KINGKRETE will produce high quality concrete of improved durability by reducing concrete permeability and water absorption.
Why use it
- More durable concrete, lower in permeability.
- Provides concrete protection through-out the concrete depth.
- Chloride and bitumen free.
COMPATIBILITY
KingAdd 50WP can be used with all types of Portland cement and cement replacement materials.
KingAdd 50WP is compatible with KingAdd 52WP and other KINGKRETE high range water reducing admixtures when used in the same concrete mix. If more than one type of admixture is to be used in the concrete mix, they must be dispensed to the concrete separately.
Technical properties

DOSAGE
The guidance dosage of KingAdd 50WP is 1.0 - 2.30 litre per 100 kg of cementitious materials in the mix, including GGBFS, PFA or microsilica.
Representative trials should be conducted to determine the optimum dosage of KingAdd 50WP to meet the performance requirements by using the materials and conditions in a actual use.
POINTS TO BE CONSIDERED IN WATERPROOF CONCRETE
- Lower water to cement ratio gives lower permeability concrete.
- Good concrete placing and compaction are very important to produce waterproof concrete.
- Fresh concrete should be protected against rapid drying and cured properly.
- Cold joints must be avoided.
How to use
Method of use
KingAdd 50WP should be added to the concrete with the mixing water to achieve optimum performance.
An automatic dispenser should be used to dispense the correct quantity of KingAdd 50WP to the concrete mix.
Cleaning
KingAdd 50WP can be washed with fresh cold water.
