Sakret ZF M-10 Cement-based Mortar and Plaster with Antifreeze Additive -10ºC 25kg

Sakret ZF M 10 Cement for masonry with antifreeze additive - Cement for masonry with antifreeze additives (up to -10°C). For exterior and interior work; suitable for all types of brick or block walls (according to EN 998-2 standard, strength class M 10); also suitable for plastering in one or more layers (according to EN 998-1 standard, class CS IV); can be mixed by hand or with a mixer; particle size up to 2mm.

Application:

• The base must be firm, stable, and free of cracks
• Bricks or blocks must be clean and dry, they must not be frozen or thawed
• Clean the base from less stable and/or detachable layers
• Especially dense and/or smooth bases should be treated with abrasive material
• Highly absorbent surfaces should be primed with SAKRET BG primer or SAKRET UG primer (diluted in a ratio of 1:3)
• Especially smooth concrete surfaces should be primed with SAKRET QG primer
• Mix SAKRET ZF in a clean container with cold water (use warm water in winter conditions) until a homogeneous mass without lumps is formed
• It is recommended to use a mixer with 600 revolutions per minute
• The temperature of the mortar during construction should not be lower than +8°C
• Immediately after completing the construction, the structure should be covered, first with a waterproofing material and then with thermal insulation material, such as polyethylene film and mineral wool boards
• The temperature of the base or formwork should be such that the concrete does not freeze before reaching the critical or calculated temperature of hardening, minimum +5°C
• Mortars with a strength class not lower than M5 can be used
• All bricks and blocks should be cleared of snow and ice before masonry
• It is recommended to perform thermal calculations for the concrete structure (setting time of concrete, required thermal insulation properties, concrete pouring temperature)
• Above +5°C, antifreeze additives act as accelerators of hardening
• Technical data refers to a temperature of +20°C and 50% relative humidity. Lower temperature increases, higher temperature decreases the specified values
• Protect the mortar during the hardening phase from sunlight, drafts, and excessively high temperatures (>30°C)
• Protect fresh mortar from rain and excessively rapid drying
• Once the mortar has started to set, water should no longer be added!
• Immediately after preparing the mortar, rinse the containers and tools with water
• Hardened mortar can only be removed mechanically
• Contains cement, reacts alkaline
• Protect skin and eyes, follow the technical instructions. If the mortar gets into the eyes, rinse with plenty of water and, if necessary, seek medical attention
• Protect the packaging from the effects of weather, store on wooden pallets, in a cool and dry place, immediately cover any opened packaging
