Processing

Blocks or bricks must be clean and dry, not iced or frozen

Clean the base surface from less persistent and/or separable layers

Especially water-absorbing bricks/blocks should be moistened

Mix SAKRET GMS-F 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

After the ripening time (~3 minutes) mix again

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
