Multimix Evo

Multimix Evo is a pre-mixed fibre-reinforced mortar for walls and floors.

Instructions for use

Preparation for use
The substrates must be clean and sound, free of oils and greases, dust, crumbly material and dirt in general. Any residues of release agent must be carefully removed. Remove any loose, crumbling, inconsistent parts until the sound, durable substrate is reached. Wash the entire surface to be treated with pressurized water to remove all traces of dust or other loose material. In the case of very absorbent substrates, wet beforehand.

Product preparation
Mix Multimix Evo with 20-23% of clean water (equal to 5,50-6,00 litres per 25 kg bag) in the following way: in a special container pour almost all the necessary water, then add the powder product slowly, stirring at the same time while the mixture is forming using a low-speed drill with a specific propeller. Once all the powder has been added, pour in the remaining water and stir until the mixture is homogeneous and free of lumps, taking particular care to remove lumps of unmixed material from the walls and bottom of the container. Allow to stand for approx. 5 minutes, then mix briefly. The prepared mixture remains workable in the mixing containers for about 30 minutes under normal conditions (at 20 °C); higher temperatures shorten the workability time, while lower temperatures lengthen it. In case of substrates with difficult adhesions, a preliminary layer of Multigrip should be applied.

Instructions for use
Apply Multimix Evo with an American trowel in case of skimming or with masonry trowel and/or a straight edge tool in case of higher thickness (never exceed 50 mm overall). The product can also be applied with a suitable plastering machine after setting it up correctly. In the case of recovery operations or in general in the presence of discontinuous, irregular and/or cracked surfaces, it is advisable to apply the product in two subsequent coats, fitting an alkali-resistant glass fibre reinforcement mesh between one coat and the other. After leaving the applied product to cure well (in normal conditions about 30 minutes; times may vary depending on environmental conditions and the type of substrate), finish with a spatula or sponge plastering trowel depending on the type of finish desired. If necessary, after 24 hours, the surface can be further optimised/levelled with a special plaster robot/levelling machine. Applications made with Multimix Evo must be protected from direct sunlight and for at least 24 hours in the event of rain; ensuring that the product applied is protected from frost for at least 7 days.

Cleaning
The tools used for laying can be cleaned with water before the material hardens; afterwards cleaning can only be carried out by mechanical removal.

Storage

Multimix Evo must be stored in a dry and sheltered place. In the original closed bags it is kept for at least 12 months. PROTECT FROM MOISTURE.

Warnings

• Do not apply Multimix Evo at temperatures below +5 °C or above +30 °C.
• Never mix with other binders such as cement, hydraulic lime, gypsum, etc.
• Do not use the mixture no more and do not add water when it is no longer workable. Take care to prepare from time to time a quantity of product that can be applied within its workability time.
• Due to the quick-setting of the product it is recommended not to make large façades exposed to heat in a single pass or use the Multimix product.
