Surface: Terrazzo Floor

Services: Terrazzo Floor
Restoration and Protection

Location: Victoria Library, London

Description:

To restore the terrazzo floor to its optimal condition, we propose a mechanical resurfacing approach. This will involve the following steps:

1. Cleaning and Grinding:

   The floor will be mechanically ground down using a professional floor grinding machine equipped with artificial diamond abrasives. This process will remove approximately 1-2 mm of the surface, effectively eliminating topical damages such as indentations, scratches, and etch marks. The grinding will also address surface stains, restoring the terrazzo to a uniform base state.
2. Polishing:

   Following the grinding phase, we will re-polish the surface to achieve a matte to silky finish. This step enhances the natural beauty of the terrazzo, ensuring a high-quality aesthetic outcome suitable for a conserved public space.
3. Crack and Chip Repairs
   Our cost estimate includes the repair of up to five significant cracks or chips in the terrazzo floor. The repair process will involve:
   • Materials and Technique:
   We will use a combination of deep-penetrating resin to stabilise the floor structure and a topical application of coloured polyester glue mixed with stone chips matched to the terrazzo’s appearance. This ensures both structural integrity and visual continuity.
   • Limitations:
   Please note that this scope does not cover hairline cracks.
   These will require an on-site assessment to determine whatever
   are feasible for repair or not. Should additional structural repairs be required, we can provide a supplementary quote following the evaluation.
4. Protective Sealing Recommendation
   To ensure the restored terrazzo floor meets safety standards and retains its condition over time, we recommend the application of a protective sealer. Our proposed solution is designed to achieve a pendulum slip test rating of 36 PTV in both dry and wet conditions, complying with safety requirements for public spaces.
