Concrete: Corroded and carbonated concrete and any loose elements should be carefully removed. Any stains the layer of cement wash, anti-adhesion agents, old layers should be mechanically removed. The substrate of the concrete should be rough and porous, ensuring good adhesion. Reinforcement: The corroded reinforcing bars should have the concrete support removed up to the places which are not corroded. Before the application of CERESIT CD 25, the uncovered reinforcing bars should be covered with anticorrosion protection CD 30 twice. Concrete substrates should be sprayed with water without any puddles formed and then the slightly damp substrates and the previously protected reinforced steel should be covered with the contact layer CERESIT CD 30.
Preparation of the mortar: The content of the packaging should be poured to the measured amount of clean water and mixed with the slow rotating drill with a mixer until the homogenous mass without lumps is obtained. Then it is necessary to wait 3 minutes and mix the mortar once again.Application of the mortar: Within the pot life the ready mortar should be applied with the trowel on the freshly applied contact layer or poured to the form and it should be properly structured.Additional protection of concrete: The additional protection for concrete against corrosion, harmful water impact, frost, aggressive agents and weather is to cover the mortar of CERESIT CD 25 with acrylic paint CERESIT CT 44 or flexible insulation layer CERESIT CR 166.
Additional cover the mortar of CERESIT CD 25 with acrylic paint CERESIT CT 44 or flexible insulation layer CERESIT CR 166 can be applied after 3 days when CD 25 has been applied. Use CD 25 only in dry conditions, the temperatures ranging from +5 to +30°C and relative humidity below 80 %. The mortar should be protected against too fast drying caused by the strong insulation, draughts, etc
As part of CERESIT PCC system, CERESIT CD 25 is designed for filling crack/voids, re-profiling balconies, as well as for making the complex repairs for various types of cement and reinforced concrete structures. It allows for repairing the structures even when they have been severely damaged due to exploitation or destruction under the influence of mechanical or corrosive factors. It is suitable for repairing the following types of constructions: balconies, overpasses, reinforced concrete ditches, ceilings, etc. It may also be used for repairing such construction objects as concrete and reinforced concrete tanks (including waste treatment plants), flyovers, frame structures and multi board structures, monolithic structures (including swimming pools), reinforced concrete, chimneys, refrigerators, etc.
