Approximately 6 kg/m² of SANALIT for every centimetre of thickness to be implemented (approximately 600 kg per cubic metre).

Use fields

For laying subbase screeds in high performance thermo-acoustic ecological buildings.

Preparation of supports

Application surfaces should be clean, free of soiling, crumbling and non-adhering parts, dust, etc., conveniently saturated with water until they reach the condition "saturated with dry surface".

Use method

Pour about 2/3 of the mixing water into the mixer. Gradually add SANALIT and the water still needed, by mixing until a homogeneous lump-free mixture of the desired consistency is obtained. Support the product at the reference height and float until a smooth and planar surface is obtained, preparing the joints beforehand where necessary. The mixing water indicatively necessary is equal to 65-75% by weight (8.5 -9.5 litres per 13 kg bag).

Application methods

- Finishing trowel

- Pump

- Spatula

- Straight edge

Tool cleaning

- Water

Permitted supports

- Concrete

- Floor screed

Warnings, precautions and Ecology

It is always essential to carry out preliminary tests to check the appropriateness of the product, depending on specific requirements.

Protect fresh surfaces from direct exposure to sunlight, from the rain and the wind, and cure the prolonged moist hardening.

Please note that SANALIT is only intended as a subbase for subsequent cement or lime-based slabs. It should not be used as a top trampling layer.
