KingAdd 200LW®
Air enteraining agent for concrete.
SpecWorld has the Spec Pack, CSI specification and drawings for registered specifiers.
Overview
KingAdd 200LW is a liquid foaming agent used to produce light weight foam concrete. KingAdd 200LW should be used with appropriate foam generator to produce consistent Pre-foam which when mixed with cement only or with sand/cement mortar will produce light weight mixes with densities between 300 – 1500 kg/ m³.
Where to use
- Light weight concrete produced with the aid of KingAdd 200LW is typically used in the following applications:
- Roof thermal insulation.
- Under-floor heat insulation.
- Light weight block.
- Void filling.
- Trench reinstatement.
Why use it
- Gives excellent thermal insulation with good compressive strength.
- Excellent foam stability.
- Can be used with all types of cement.
COMPATIBILITY
KingAdd 200LW can be used with all types of Portland cement and cement replacement materials.
KingAdd 200LW is compatible with other KINGKRETE admixtures used in the same mortar mix.
If more than one type of admixture is to be used in a mortar mix, they must be added to the mortar separately.

DOSAGE
The guidance dosage of KingAdd 200LW is 0.8 - 2.0 liters/ m³ of foamed concrete. The exact dosage depends upon the required final dry density. The optimum dosage of KingAdd 200LW to achieve the desired dry density should always determined by site trials.
Effects of Over Dosage
Overdosing of produced pre-foam to the pre-batched mixture will lead to a lower densities and reduced compressive strength.
How to use
Method of use
An appropriate foam generator should be used to produce a pre-foam by mix feeding KingAdd 200LW, potable water and compressed air.
The pre-foam is then fed into pre-batched cement/water slurry or sand/cement /water mortar and mixed for 3 - 5 minutes to achieve a homogeneous mixture. The liquid foamed concrete is then pumped using a proper screw pump and placed at the required thickness and slopes.
Cleaning
KingAdd 200LW can be washed with fresh water.
Coverage, packaging and storage
Packaging
KingAdd 200LW is available in 25 liters pails, 210 liters drums and 1000 liters bulks supply.
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.
