Concrete protection and repair

slider

In case of small concrete repairs and maintenance a fast and easy solution is to apply the multi-talent KÖSTER Betomor Multi A. KÖSTER Betomor Multi A is a material for corrosion protection and concrete replacement. An additional corrosion protection is not required. KÖSTER Betomor Multi A replaces the bonding agent, the repair mortar and the spackle. The material is applied onto the prepared, stable substrate which must also be free of separating agents and rust.

For application overhead KÖSTER Betomor Light 88 is ideally suitable.

Repair and maintenance of concrete surfaces is done with KÖSTER C-Coat. KÖSTER C-Coat is a high quality spackle for levelling and smoothing concrete surfaces.

For reprofiling and concrete replacement in larger areas, KÖSTER Repair Mortar NC is applied. It is suitable for trowel application and can be spray applied as well. The mortar is applied onto the prepared, stable substrate which must also be free of bond inhibiting agents. Reinforcement steel has to be cleaned, as corrosion protection and bonding agent KÖSTER Z1 / Z2 is applied.

Non water bearing cracks are sealed with KÖSTER IN 3. This injection resin has excellent bonding characteristics to concrete crack flanks and is used for the structural bonding of building elements.

Always adhere to the specifications in the respective Technical Guidelines.

Concrete repair of balconies and terraces

Maintenance of concrete, e.g. repair of balconies and terraces normally requires corrosion protection for the reinforcement steel, a bonding agent, repair mortar and a spackle.

KÖSTER Betomor Multi A fulfils all of these requirements in one product. The advantage is that only one product is needed for the renovation. This provides an easier calculation of the required amount and logistics. Concrete repair of building elements can be quickly and easily done with KÖSTER Betomor Multi A, for overhead application KÖSTER Betomor Light 88 is ideal due to its density of 0.88 g / cm³.

Maintenance of concrete surfaces is done with KÖSTER C-Coat. KÖSTER C-Coat is a high quality spackle for levelling and smoothing of concrete surfaces. KÖSTER Silicon Paint White is an optimal decorative paint coating for concrete surfaces.

The elastic and crack bridging waterproofing material KÖSTER NB Elastic (Grey or White) is applied as the waterproofing layer on balconies and terraces. The material is resistant to foot traffic or can be covered with tiles. In the wall / floor junction and in areas in danger of cracking KÖSTER Flex Fabric is embedded between the two waterproofing layers. Fillets are made with KÖSTER Repair Mortar Plus.

Always adhere to the specifications in the respective Technical Guidelines.

Corrosion protection of concrete

orrosion protection on concrete is usually done with a system of KÖSTER Bridge Coat and KÖSTER PUR-Bitumen, applied by brush or roller. The system is crack bridging.

Alternatives:
In case of minor acid impact, if no crack bridging is required, the coating can alternatively be carried out only with two layers of KÖSTER Bridge Coat.

In the case of extraordinarily high acid impact (e. g. when below the acid dew point) the entire coating is to be carried out with two layers of KÖSTER VE. In addition KÖSTER VE is suitable for the covering of edges, holes and screws prior to the application of KÖSTER Bridge Coat.

The surface is prepared by sand-blasting, grinding or shot-blasting until a solid and stable substrate for the subsequent coating is ensured.

For reprofiling and concrete replacement KÖSTER Repair Mortar NC is applied. It is suitable for trowel application or can be spray applied. The mortar is applied onto the prepared, stable substrate which must also be free of bond inhibiting agents. Reinforcement steel has to be cleaned, as corrosion protection and bonding agent KÖSTER Z1 / Z2 is applied.

Rough and highly absorbent substrates are prepared with KÖSTER NB 1 “fast”.

Always adhere to the specifications in the respective Technical Guidelines.

Because corrosion protection on concrete requires experience and should be analyzed case by case, please contact our technical consultants. They will be glad to answer your questions.
