Method of using repair mortar MTOSIVE 1020

Substrate preparation:

• The desired surface should be clean and free of any polluting materials, and weak and weak points of concrete should be identified and destroyed.
• These areas are cut to a depth of 10 cm and care should be taken to have a sharp and square shape where possible. Also, maintain a minimum thickness of 10 mm around the repaired area.
• The desired surface should be uneven and have at least 5 mm unevenness with 20 mm intervals.
• If dirty and loose surfaces are dealt with, it is better to coordinate with the supervisor of the workshop so that possible cleaning and cutting can be done.
• If you see painted reinforcements, first ensure its internal health, then remove the rust by one of the methods of brushing or sandblasting until the surface of the steel is clean.
• Double protection of reinforcements will be possible by special coatings.
• In cases where the reinforcements have extensive corrosion, they should be replaced.

Impregnation with water:

Saturate the desired surface completely by washing with water, then collect the excess amounts from the surface.

If the above mixture does not have the desired concentration, you can gradually add water to it and continue stirring for another 1 to 2 minutes. Obviously, the amount of water required is influenced by the relative humidity and temperature of the environment.

Performance:

The prepared mixture can be applied by hand or sprayed, and in case of manual application, the trowel should be pressed on the mortar surface to ensure complete contact between the mortar and the previous surface. For this purpose, use a plastic or wooden trowel, but Finish with a metal trowel.
The best time to apply the finishing work is when fingerprints are barely visible on the surface of the repair mortar.
