Substrate preparation

Ceresit CX 5 EXPRESS quick setting mortar can be used on compact, load-bearing and clean substrates free of adhesion-reducing substances, such as fat, bitumen, dust. The substrate should be moistened with plenty of water without creating a puddles. In the case of blocking local water leaks, the existing gap should be disassembled in such a way as to create a possibility of the Ceresit CX 5 EXPRESS filling jamming into it. For anchoring a fitting hole of appropriate diameter should be forged or drilled. The clearance between the anchor element and the surface of the mounting hole should not exceed 20 mm (for clearance above 20 mm sand can be added).

Application

Example: Quick assembling with CX 5 EXPRESS

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
