REPAIRCONCRETEStrong Floor 90 - KRAFT Paints

High-performance polymer modified cementitious levelling compound for industrial floors.

KRAFT STRONG FLOOR 90 is a one-component cement based levelling compound, polymer modified, suitable for laying on heavy duty industrial floors and on urban features and fittings. It can also be used for precise anchoring and for structural grouting metallic structures. It can be pumped or manually applied on interior or exterior floors up to 80mm thickness. Due to its low porosity surface, it can be used as the finishing layer or as the subfloor for epoxy or polyurethane flooring systems. It meets the minimum requirements of EN 13813 (CT-C80-F15-A1.5), ΕΝ 1504-3 (R4) and ΕΝ 1504-6.

Instructions

SURFACE PREPARATION
» Substrate must be sound with adequate compressive strength (>25N/m2) and tensile strength (>1.5N/mm2), clean, and free from oil, grease, loose material, surface contaminants, and other bond-inhibiting materials.
» Surface treatments or any friable areas of the substrate must be mechanically removed and the substrate repaired with KRAFT STRONG REPAIR. Old, loose and weak levelling layers should be removed mechanically.
» Saturate concrete surface with clean water or prime with KRAFT POWDER BOND diluted 1:4 with water.

APPLICATION INSTRUCTIONS
» 
KRAFT STRONG FLOOR 90 can be mixed with a low-speed electric drill mixer (300-400rpm). Pour water into a suitable mixing container and add the dry powder slowly while mixing. Mix thoroughly at least for 3 minutes, until the proper lump-free consistency is reached. Let the mixture stand for 3 minutes and remix for 15 seconds and use.
» Apply KRAFT STRONG FLOOR 90 mortar by low pressure or by trowelling depending on the application.
» Immediately after application spray the surface with water and repeat spraying after initial drying.
» On large surfaces, it is recommended to create expansion joints per 40m2.
» Pot life of the mixture: 45min at 25°C.|
» Let the material to set for 24 hours before loading any weight.
» Cleaning: Immediately after use, wash the tools with hot water and soap or detergent, along with product residues. Once it has set, cleaning may only be carried out by mechanical means

PRECAUTIONS
» Do not apply at substrate and air temperatures below 5ºC and above 35o Recommended substrate temperature is between 15ºC and 25ºC.
» Do not add cement or other inert materials to KRAFT STRONG FLOOR 90 mortar.
» Do not add water more than the recommended quantity. Do not add water once the mix has started to set.
» The recommended maximum film thickness is 80mm per layer.
» At temperatures below 20ºC, the product needs more time to be hardened.
» Protect from rain, humidity and water contact for 24 hours after application.
» Protect newly applied material from direct sunlight, hot or strong wind and high temperatures in order to avoid cracking.

STORAGE

» Stored for 12 months by the production date in its close and sealed packages, in dry and cool condition preferably on pallets
