Step by step

Substrate preparation

 

Ceresit CX 20 COMFORT mortar can be applied on compact, load-bearing and clean substrates free of substances that reduce adhesion, such as: fats, bitumen, dust. The substrate should be forged or drilled with a mounting hole of min. 5 mm larger than the embedded element. In the case of larger cavities, the gap should be disassembled in the so-called swallow tail.

 

Before application, the substrate should be moistened abundantly with water. Apply the material on matte-moist substrates. In the case of reconstruction of damaged elements, it is recommended to apply the mortar to the substrate with a hard brush and then apply the material “fresh on fresh” in one technological cycle.

Application

 

Example: Reconstruction of damaged concrete stairs with CX 20 COMFORT

  1. Check production date and all technical requirements and prepare the right amount of CX 5 EXPRESS.
  2. Do all the preparation for element fixing before CX 5 EXPRESS is mixed with water - set the element in the correct position.
  3. Measure the amount of water needed and pour into the bucket for mixing.
  4. Pour the specific amount of CX 5 EXPRESS into the water
  5. Stir until homogenous without lumps (approx. 30 s.)
  6. Assemble element with CX 5 EXPRESS to prewetted substrate immediately after mixing
  7. Mortar will set very quickly – make sure to provide proper levelling and stability of bonding
