Many of our customers wonder how to renovate an old tiled staircase and whether it is possible to do so without removing the tiles. The answer to these questions is microcement. However, before you apply decorative concrete to your stairs, you need to prepare it properly. The right treatments before the microcement is applied will ensure that it adheres well to the substrate and that the joints won’t show through.
Steps for renovating a tiled staircase:
1. Before applying microcement to the tiles, roughen them with a sander.
2. Fill the joints with tile adhesive or other mortar.
3. Then lay a bonding bridge with a fibreglass mesh or a base with a mesh.
