Oxford School Stone Restoration: Building Durable, High-Performance Flooring for a Busy Educational Campus
Oxford School Floor Stone Restoration Work
Transforming a High-Traffic Floor into a Long-Term Asset
At Oxford School, Mumbai, stone flooring plays a critical role in daily campus operations, supporting constant movement from students, teachers, and staff. Over time, approximately 1,000 square feet of stone flooring had become heavily stained, dull in appearance, and increasingly difficult to maintain. Despite earlier treatment attempts, the surface continued to absorb stains and required intensive cleaning.
Over the course of one week, we implemented a structured stone restoration and protection program designed to address deep contamination, improve internal strength, and enhance long-term performance. The result was a cleaner, denser, and stain-resistant stone surface that significantly reduced staining complaints and improved day-to-day maintenance efficiency.
The School Environment and Site Conditions
Oxford School is an active learning facility that has consistent movement of students on a daily basis. Some products, such as milk, snacks, ink food, shoe impressions and chewing gu,m often spill and leave traces in corridors and common areas.
The flooring was C2 stone mixed with some other natural stone that had to be chosen because of their visual appeal. This, however, was not the case as the surface being exposed was quite porous, thus subject to staining and hard to clean. Past surface treatments had not provided any long-lasting protection, and the school continued to have aesthetic as well as maintenance problems. A resolution had to be found that would come up with something that would not be affected easily, to the point that safety or aesthetics would be put into question.
Why the Existing Stone Surface Was Failing
The main problem was that the porosity of the stone was too open and therefore dirt, moisture and provoking agents were able to go beneath the surface. Gradually, impurities were incorporated in the stone such that it was hard to clean.At the time of our assessment, the stone surfaces showed clear signs of post-construction impact. Grout marks and embedded dirt were visible across multiple areas, leading to uneven appearance and loss of natural colour depth.
It also had prior layered surface protection treatment, which was not appropriate in high-traffic school conditions. It also lacked structural reinforcement and the dependability of stain resistance and deteriorated easily during daily usage. Consequently, there was systemic staining and an increase in maintenance, even after cleaning the school premises.
Our Restoration Approach: From Contaminated Stone to Durable Flooring
To restore the flooring effectively, we followed a process-driven methodology that focused on structural improvement, controlled densification, and practical stain protection.We implemented a structured and site-specific stone restoration programme, carefully planned to address post-construction residues and prepare the stone for long-term protection.
Surface Preparation: Creating a Clean Base
We started with a systematic stripping ram with a machine, of about 0.5 mm of the surface. This was done to cleanse deeply rooted dirt, grime, and remnants of the previous treatments. It has also helped to open the pores of the stone and reveal its cracks and empty spaces so that we could observe the substrate properly. This phase was crucial in making sure that the rest of the treatments were able to enter the body and deliver positively.
Structural Stabilisation with Flagpox 1005
After the surface was ready, we repaired all of the visible cracks and voids with Flagpox 1005, a two-component resin/epoxy-based adhesive in the form of gels. Its viscosity was in fine control, it was gel-like in nature and could be applied precisely and it could penetrate the surface deeply without spreading. Once the epoxy had cured, weak spots were reinforced such that the resultant structure is stable and smooth enough to take up heavy foot traffic and sustain the densification and polishing process.
First-Stage Densification with Densi-Shield 200
Once the surface was ground to 200 grit, we put on Densi-Shield 200, which is a water-based densifier that is used to cut deep into the stone. This treatment made the surface harder inside, less dusty and more resistant to abrasion without any change of the natural appearance of the stone. It was prepping the floor to be more polished with its internal equipment being enhanced.
Second-Stage Densification with Densi-Shield 800
After additional grinding to 800 grit, we sprayed the stone with Densi-Shield 800 to provide more density and strength. The step minimised micro-porosity and enhanced resistance to wear and also greatlyimproved performance when subjected to constant foot traffic. The stone was condensed and made strong to guarantee durability in the long term within a school setup.
Polishing to 1500 Grit: Balancing Finish and Safety
We polished the surface to 1500 grit, achieving a smooth, uniform finish that improved brightness and cleanliness while maintaining adequate slip resistance. This level of refinement was deliberately chosen to ensure the flooring remained safe for children while enhancing its overall appearance.
Final Stain Protection with Protex
Finally, we used Faber Protex, a solvent-based, fast-drying stain-resistant finish. It develops an invisible shield of protection that postpones the liquid uptake, giving time to wash spills before they infiltrate the stone. It offers a high level of resistance to various common staining agents like milk, oil, coffee and food, and does not create an overlay over the stone but instead creates a coating on it.
Results: Improved Performance and Easier Maintenance
After completion, the flooring showed a visible improvement in cleanliness, uniformity, and density. Daily cleaning became easier, as dirt and spills no longer penetrated the stone as quickly.The completed works resulted in an immediate and visible improvement. All construction residues were removed, and the stone’s natural colour, pattern, and surface clarity were restored.
Key observed outcomes included:
- An estimated 70 per cent reduction in staining-related complaints
- Approximately 40 per cent reduction in daily cleaning effort
- Improved resistance to heavy foot traffic and routine school spills
The stone flooring transitioned from a constant maintenance challenge into a durable, easy-to-manage surface suitable for long-term institutional use.
Key Takeaways from the Project
Several critical lessons on high-use environments are strengthened in this project. Surface coatings do not achieve much better results over a long period than structural strengthening and densification. Effective reduction in porosity and enhancement of stain resistance need a multi-stage densification process. Sample testing assists in proving the performance prior to full-scale implementation. It is important that appearance and safety are put in balance in schools. Most importantly, all that a failed treatment of the past is there to show that the stone itself is not in demand; it is just that the appropriate process was not used yet.This project reflects our strength in delivering outcome-focused stone cleaning services, stone restoration works, and stone protection solutions for high-use entrance and lobby environments. Our technical understanding of natural stone, disciplined execution process, and use of proven stone care systems allow us to deliver finishes that meet both visual expectations and long-term performance needs. We ensure that stone surfaces look refined at handover and continue to perform reliably throughout their service life. The entrance and lobby areas at Godrej Trilogy are high-visibility common spaces that experience constant daily movement. These zones are designed to create a strong first impression while also performing under long-term operational use.
