- 45 ± 5%
Overview
KingHard S100 is a clear, surface hardener and dust proofer designed for application to concrete and other cementitious floors. KingHard S100 is based on an aqueous solution of sodium silicate and wetting agents to enhance surface penetration.
KingHard S100 is mixed with water and applied to concrete surfaces. Use of KingHard S100 will increase abrasion resistance and reduce dusting of concrete surfaces.
Where to use
KingHard S100 is recommended for new and old cementitious surfaces, such as concrete floors and granolithic paving. It should not be used to renovate concrete which is already disintegrating. Typical applications include:
- Factories.
- Warehouses.
- Garages.
Why use it
- Improves abrasion resistance.
- Single component.
- Durable.
- Cost effective.
- Easy application.

New Concrete Flours
New concrete surfaces must be allowed to cure for 14 days prior to application of KingHard S100.
How to use
Substrate preparation
The substrate must be clean, dry, structurally sound, dense and free from oil, grease, dust and other contaminants. A clean surface will ensure maximum penetration of KingHard S100 into the concrete surface.
Surfaces contaminated by oil or grease should be treated with suitable chemical de-greaser then washed with clean water.
Areas deeply contaminated by oils or grease, should be treated by hot compressed air.
All contamination and laitance must be removed before KingHard S100 application to allow for effective penetration.
Mixing
Mix one part of KingHard S100 with 3 parts of clean water, use slow speed drill for mixing for 2 minutes until a homogenous mixture is achieved.
Application
The mixed (diluted) KingHard S100 should be poured onto the surface of the floor and spread evenly with a soft brush or squeegee avoiding the formation of puddles.
The first coat should be applied at a uniform rate of approximately 9 - 10 m²/litre of the mixed (diluted) KingHard S100. Allow the solution to be absorbed for a period up to 2 hours, while the floor is still damp, the surface should be washed off and rinsed with clean cold water to prevent excess KingHard S100 mixture crystallizing on the surface. This is necessary to avoid unsightly white dusting.
The surface should be allowed to dry for a period of 24 hours to be ready for the second coat which should be applied at same procedures of first coat. Only in the case of very porous floors would a third coat be necessary.
REMARKS
Coloured surfaces must be allowed to cure for 28 days prior the application of KingHard S100. It is advised to test a small area to evaluate the effect of KingHard S100 on the colour.
Concrete surfaces must be dry to maximize penetration.
Cleaning
Tools and equipment can be cleaned with clean cold water.
Coverage, packaging and storage
Coverage
The coverage rate of the mixed (diluted) KingHard S100 is: 10 m²/litre per coat for one application, 7.5 m²/litre per coat for two applications and 5 m²/litre per coat for three applications.
Packaging
KingHard S100 is available in 25 litre pails and 200 litre drums.
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.
