BF / Concrete Floor / Concrete with Antifreeze Additive

Details:

• Suitable for work at temperatures down to -10°C
• Concrete class C25
• Designed for the production and repair of concrete and reinforced concrete structures
• Suitable for heated floors
• Excellent mechanical and climatic durability
• High resistance to aggressive environments
• Water and frost resistant

Preparation:

• The substrate or formwork must not be frozen.
• The substrate must be firm, stable, and free of cracks.
• Clean the substrate from less durable and/or removable layers.
• Particularly dense and/or smooth substrates should be treated with abrasive material.
• Highly absorbent surfaces should be primed with SAKRET BG or SAKRET UG primer (diluted at a ratio of 1:3).
• Especially smooth concrete surfaces should be primed with SAKRET QG primer.
• Mix SAKRET BF in a clean container with cold water (use warm water in winter conditions) until a homogeneous mass without lumps is formed.
• Follow all preparation conditions for SAKRET BE specified on the product packaging.
• After a maturation time (~3 minutes), mix again.
• When pouring, use non-absorbent or weakly absorbent formwork.
• In reinforced concrete structures, ensure adequate cover for the reinforcement.
• For large horizontal structures, observe the intervals for deformation joints.
• Treat formwork with formwork oil.
• Place concrete evenly in the formwork and compact it.
• Apply the concrete at the required layer thickness, compact, level, and smooth.
• Do not fill deformation joints with concrete!
• The temperature of the construction mixture during pouring must not be lower than +8°C.
• After completion of the work, structures must be immediately covered, first with waterproofing material and then with insulating material, such as polyethylene film and mineral wool boards.
• The temperature of any substrate or formwork must be such that the concrete does not freeze before reaching the critical or calculated temperature during hardening, minimum +5°C.
• Use mortars with a class no lower than M5.
• All bricks and blocks must be cleared of snow and ice before masonry.
• It is recommended to perform a thermal calculation for the concrete structure (concrete cooling time, required insulation properties, concrete laying temperature).
• Above +5°C, anti-frost additives act as hardening accelerators.
• Technical data refer to a temperature of +20°C and a relative humidity of 50%. Lower temperatures increase, while higher temperatures decrease the indicated values.
• Protect the mixture during the curing phase from sunlight, drafts, and excessively high temperatures (>30°C).
• Protect fresh mortar from rain and excessive drying.
• Once the mortar begins to set, do not add water!
• Immediately after preparing the mortar, wash containers and tools with water.
• Hardened mortar can only be cleaned mechanically.
• Contains cement, reacts alkaline.
• Protect skin and eyes, and adhere to technical instructions. If the mortar gets into the eyes, rinse with plenty of water and seek medical attention if necessary.
• Protect packaging from weather influences, store on wooden pallets in a cool, dry place, and immediately cover opened packaging.
