Substrate preparation

1. Substrates must be clean, free of oily residues, loose materials, dust etc.
2. Dampening of the substrate before application is necessary.
3. Remove rust from reinforcements and follow with rust primer application.

Mixing instructions

1. Add 4 – 4,5 kg of water in a clean bucket and gradually under constant stirring add 25kg of ISOMIX MECHANIC.
2. Using a low speed electrical mixer (or concrete mixer) stir well till a uniform tight mass appropriate for repair work is formed.

Application

1. The mixture should be applied (pressed) on the surface with a trowel or gunning device at the desired thickness, up to 30 mm per layer.
2. The working time of the mixture is 2 hours. Periodical stirring is advised while avoiding the addition of more water.
3. If a second layer is required it is advisable to roughen the first layer in order to achieve better adhesion.

REMARKS

The final surface should be protected from rapid dehydration especially at high temperatures. Repeated dampening is recommended for 48 hours, covering the treated surface with wet clothes or polyethylene sheets.
