PREPARATION


The mortar type M-7.5 packed in bags is prepared in a concrete mixer. Add 3.2 liters of water for each bag of mortar (0.125 liters / kg). Depending on the application, it can be up to 3.5 liters (0.14 liters / kg of mortar).

HOW TO USE


The support must be clean and damp. Do not apply to paint, plaster or dissolvable surfaces.

Spread the paste on the support or piece with the help of a trowel or trowel depending on the application

For factory works a soft consistency between 170 and 180 mm of runoff is recommended

For plastering or rendering, it is recommended to give it a fluid consistency of > 190 mm.

The mortar use time in optimal conditions is 90 minutes, depending on the weather.

It is recommended not to use them when it is expected that the temperatures in the setting process could exceed 40 °C or the temperature could drop below 4 °C.
