Processing

The base surface or moulds must not be frozen

The base must be firm, stable and without cracks

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 BF in a clean container with cold water (use warm water in winter conditions) until a homogeneous mass without lumps is formed

Follow all the preparation conditions of SAKRET BE indicated on the material package

After the ripening time (~3 minutes) mix again

When concreting, use non-absorbent or weakly absorbent forms

Provide a sufficient protective layer of reinforcement in reinforced concrete structures

For the surfaces of large horizontal structures, observe the intervals of deformation joints

Treat the moulds with mould oil

Place the concrete in the formwork evenly and seal

Apply the clone in the required layer thickness, seal, level and smooth

Do not fill the deformation joints with concrete!

The temperature of the construction mixture during concreting work must 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 (cooling time of concrete, necessary 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
