ZF / Cement mortar for masonry with antifreeze additive
For work at temperatures up to -10°C
Cement based
Strength class M10
For masonry, plastering and repair works
Plastic during rubbing
Excellent mechanical and climatic resistance
Can be used for masonry of chimneys
Grey colour
High hydrophobicity and water vapor permeability
Processing
The base surface must be firm, stable and without cracks
Blocks or bricks must be clean and dry, not iced or frozen
Clean the surface from loose and/or separable layers
Particularly dense and/or smooth surfaces should be treated with an abrasive material
Highly absorbent surfaces must be primed with SAKRET BG primer or SAKRET UG primer (diluted 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 turns per minute
The temperature of the construction mixture at the time of masonry should not be lower than +80C
Constructions must be covered immediately after the work is completed, first with waterproofing and then with heat-insulating material, for example - with polyethylene film and mineral wool plates
The temperature of any base or formwork must be such that the concrete does not freeze before reaching the critical or calculated temperature during hardening min. +5°C
Mortars with a class not lower than M5 can be used
All bricks and blocks must be cleared of snow and ice before laying
It is recommended to perform a thermal calculation of the structure to be concreted (concrete cooling time, required thermal insulation properties, concrete setting temperature)
Above +5°C, antifreeze additives act as a hardening accelerator
The technical data refers to a temperature of +20°C and 50% relative air humidity. Lower temperature increases, higher - decreases the specified values
During the hardening phase of the mortar, protect from the sun, drafts and excessively high temperatures (>30°C)
Protect fresh adhesive from rain and too rapid drying
When the mortar has started to bind, no more water can be added!
Wash containers and tools with water immediately after processing the mortar
Hardened mortar can only be removed mechanically
Contains cement, reacts alkaline
Protect skin and eyes, follow technical instructions. If the mortar gets into the eyes, rinse with a large amount of water, if necessary, consult a doctor
Protect the packaging from weather conditions, store on wooden pallets, in a cool and dry place, cover torn packaging immediately
