C-FLOOR-HARDENER SURFACE HARDENER FOR FRESH CONCRETE FLOORS
Grey cement based, with mineral fillers, reinforced with chemical additives, surface hardener for fresh concrete mortar.
TSE ISO CE
ADVANTAGES
- Provides 30% increased concrete surface hardness by its mineral fillers.
- Provides reducing water absorption of the floor.
- Prevents dust formation and damages on ground because of abrasion.
- Provides suitable surface for areas exposed to heavy traffic.
APPLICATION AREAS
Applied as sprinkling by hand to create a high quality, smooth, concrete floor surface with high abrasion strength for areas that are exposed to heavy traffic (warehouses, malls, factories, concrete roads, etc.).
CONSUMPTION
5 m2 / 25 kg package (grey) 3 m2 / 25 kg package (other colors)

SURFACE PREPARATION
- Application surfaces should be clean and sound.
- Applied concrete should be minimum C25 class.
- After concrete application and levelling of surface finished, it should be strongly pressed on the surface with the thumb to check if fresh concrete surface is ready for hardener application or not.
- If the fingerprint depth is about 3-5 mm, the surface is ready for hardener application.
APPLICATION METHODS
25 kg C-FLOOR-HARDENER surface hardener is ready for use, it is applied as powder. No mortar preparation is required. C-FLOOR-HARDENER surface hardener is sprinkled uniformly and evenly on the entire concrete surface as 5 kg/m2 for grey color and as 8 kg/m2 for other colors.
Hardener is matured until it absorb water from concrete surface and get wet. Surface is smoothed by using a mechanical floating trowel.
When surface is hard enough to walk on it, surface is smoothed by a mechanical floating trowel at high speed for a second time.
When C-FLOOR-HARDENER surface hardener application is complete and the surface begins to lose its free water (when it becomes dull), CURE-AR or CURE-HR concrete curing material must be applied to the surface to prevent stress cracks and dust formation due to sudden water losses. CURE-AR or CURE-HR should be shaked before using. It is applied uniformly and evenly to entire surface by a roller, brush or a spraying machine.
Ambient and surface temperature should be between +5 ̊C and +30 ̊ during the application.
Any additional material (such as lime, cement, gypsum etc.) should not be added in to prepared mortar.
Surface should be protected from airflows and sudden temperature changes during and after the application.
Mortar should not be applied on frozen, melting or within 24 hours danger of frost surfaces.
