Marble Maintenance Schedule by Traffic Level: Lobby, Corridor and Apartment

The marble floor of a building does not wear at the same rate everywhere. The few square meters just inside the revolving door can go dull within months, while the corner of the same lobby by the window can keep its first-day shine for years. Even so, maintenance schedules are often written with a single frequency for the entire floor: the same machine every week, the same polish every year. The result is either neglected high-traffic areas or unnecessary effort spent on rarely used ones. In this article we explain the logic of setting maintenance frequency by traffic level, how to divide the floor into zone classes, why shine declines differently from zone to zone, and a task table that can be adapted for a lobby, a corridor and an apartment.

In short: In marble maintenance, the schedule is determined not by the date but by the number of feet that step on the floor and the amount of grit they carry. The floor is divided into high, medium and light traffic zones; while daily dusting is done everywhere, tasks such as polish refreshing and restoration are planned more often in high-traffic zones and less often in light ones. The schedule is updated through regular observation or measurement at set points.

Foot Count Sets the Schedule

What wears down the surface of marble is not the foot itself so much as the grit and hard particles carried under shoes. Marble, which consists of calcite, is much softer than the quartz particles in grit; each step leaves a friction mark too small to see with the naked eye. As these marks accumulate, they scatter light and the surface turns dull. So how quickly an area dulls is directly related to the number of feet passing through it and the amount of grit those feet carry.

This relationship is the basis of maintenance planning. A line where hundreds of people pass each day and a corner that only cleaning staff enter do not require the same maintenance frequency on the same floor. Setting the schedule by zone ensures the maintenance budget is spent where it is really needed and keeps the overall appearance of the floor more even.

Mapping the Traffic of the Floor

The first step in building a zone-based schedule is mapping the traffic of the floor. This does not require a complicated count; observing for a few days where people enter and where they walk, and looking at the existing wear marks on the floor, is often enough. Marble records the traffic on its own: dulled paths, half circles in front of doors and matte areas in front of elevators give the first draft of the map.

The main points to mark on the map are:

• Entrance thresholds: The first points touched by traffic from outdoors, such as the building entrance, the garage door and the garden exit, are the areas that carry the most grit.
• Turning and waiting points: In places where people stand or turn, such as in front of elevators, around turnstiles and at the reception desk, friction is greater than in straight walking.
• Main walking lines: The shortest path from the entrance to the elevator and from the elevator to the offices wears noticeably faster than the rest of the floor.
• Wheel routes: The paths followed by cargo carts, cleaning carts, luggage carts and chair wheels are noted separately, because their wear patterns are different.

The map is drawn in colors on the floor plan and shared with the maintenance team. This way, both the cleaning staff and the team doing periodic maintenance follow from the same document which zone will be handled how often.

Why Does Shine Decline Differently by Zone?

Once the traffic map is drawn, it becomes clear that loss of shine is related not only to the number of feet but also to the type of movement. In a corridor walked in a straight line, the foot touches the surface briefly and vertically. At turning points, however, the foot pivots on the surface and friction increases; so corner turns and door entrances dull more than the middle of the corridor. In front of elevators, people shift their weight on their feet while waiting, creating a small but constant friction.

The distribution of grit is also an important factor. Grit coming from outside is deposited most in the first steps after entering through the door and spreads out, decreasing toward the interior. For this reason, the area just inside the entrance suffers far more aggressive wear than the rest of the building. When mud and road salt are added in winter, this difference grows further; we covered seasonal measures for entrance areas in detail in our article on building entrances in winter in detail.

Wheeled vehicles, on the other hand, leave a distinctive mark. Hard wheels create thin, parallel lines on the surface, and unlike the dullness caused by feet, these lines follow a specific direction. On these routes, changing the wheel material is often a more effective measure than increasing maintenance frequency.

Three Zone Classes: High, Medium and Light

The traffic map generally allows the floor to be divided into three classes. The classification is not a set of strict boundaries but a framework on which the maintenance schedule is based; the boundaries are drawn differently in every building.

High-traffic zones

Entrance thresholds, the areas around revolving doors and turnstiles, the fronts of elevators, main walking lines and stair landings belong to this class. Shine drops fastest here, and grit and dirt accumulate the most. Daily dusting and cleaning can be repeated several times a day in these zones; polish refreshing is planned much more often than in other zones.

Medium-traffic zones

Floor corridors, waiting areas, passages within offices and apartment landings are medium-traffic zones. Wear here is regular but slow. Daily cleaning is sufficient, polish refreshing is done less often than in high-traffic zones, and it is often scheduled for the same night as maintenance of the high-traffic zone.

Light-traffic zones

The corners of meeting rooms, window areas, spaces under furniture and bedrooms in homes belong to this class. In these zones the shine is kept for a long time and periodic maintenance is needed very rarely. However, light zones should not be forgotten entirely; dust and stain checks are part of the daily or weekly tasks here too.

The boundaries between classes are not sharp; on both sides of a busy walking line there is a transition strip where traffic thins out. These strips should be considered separately during maintenance. When the machine refreshing the high-traffic zone works slightly beyond the boundary, the shine blends with a soft transition; when it stops exactly at the boundary, a noticeable line can form on the floor. For this reason, transition strips are marked on the map alongside the classes, and the maintenance team is told how far to extend the work.

Task Schedule: From Daily to Yearly

Once the zone classes are determined, tasks and frequencies are written for each class. Some tasks, such as dusting, are the same in every zone; others are repeated frequently only in high-traffic zones. The table below offers a general framework; frequencies should be adapted to the building's use, the season and the condition of the floor.

The most important distinction in this table is between polish refreshing and full honing. Polish refreshing only removes the thin dullness at the very top of the surface and can be done often; full honing, on the other hand, removes material from the stone and should only be done when it is truly necessary. Regular polish refreshing in heavy-traffic zones postpones the need for full honing for a long time. We explained the logic of the high-speed machines used for refreshing crystallized or polished floors in our article on high-speed polishing

Adapting It for Lobbies, Corridors and Apartments

The same framework is applied differently to different buildings. In an office tower lobby, the heavy-traffic zone covers a significant part of the floor, and the maintenance schedule is spread across night shifts. The revolving door and turnstile line is treated almost every night, while the edge areas of the lobby are maintained once a month or less often. We also covered the general framework of floor management in office towers in our article on office tower lobbies .

In a hotel or hospital corridor, traffic is more dispersed, but the areas in front of room and service doors, elevator exits and corridor intersections make up the heavy-traffic zones. Wheel traffic is also an important factor in corridors; when the wheels of cleaning and service carts are made of soft material, line-shaped wear is noticeably reduced.

In an apartment, the scale is small but the logic is the same. The entrance hall and kitchen entry are heavy-traffic, the middle of the living room and the hallway are medium-traffic, and the bedrooms are light-traffic zones. For the apartment owner, this distinction has a practical result: instead of honing the whole home, refreshing only the entrance hall and kitchen passage more often gives an appearance consistent with the shine of the rest of the home. A doormat of sufficient size in the entrance hall and taking shoes off at the door noticeably ease the schedule for this zone.

Updating the Schedule Through Observation and Measurement

A maintenance schedule should not be written once and forgotten. The use of the building changes; a new tenant arrives, a door is closed, a café opens, and the traffic map shifts. To keep the schedule up to date, the floor needs to be observed regularly at certain points.

The simplest way is to choose a few fixed points from each zone class and photograph them at regular intervals in the same light and from the same angle. For more detailed monitoring, a gloss meter can be used. This device measures how much of the light it sends to the surface at a certain angle is reflected, and gives the gloss as a number. For the measurement to be meaningful, it must be taken each time at the same point, after cleaning, and with the same device.

Measurement or photo records help adjust the schedule to reality. If gloss drops faster than expected in a heavy-traffic zone, the polish refreshing frequency is increased or the matting system is reviewed. If gloss is maintained for a long time in a medium-traffic zone, the maintenance interval can be extended. In this way, the schedule is shaped by the actual use of the building.

Owning the Schedule: Who, When, With What?

For a maintenance schedule to work, it must be clear who is responsible for which task. Daily and weekly jobs mostly fall to the building's own cleaning team; machine maintenance and polish refreshing are carried out either by a trained in-house team or by an external stone care company. Having both groups see the same schedule prevents one party's work from spoiling the other's.

The information that should be added to the schedule is as follows:

1. Task owner: For each task, it is written whether the in-house team or an external company is responsible, so that no job falls between the cracks.
2. Product and pad to be used: The approved cleaning product and machine pad are specified for each task, and product changes are made only with approval.
3. Recording method: The date, area and, if available, the measurement result of the work done are entered into a simple table and reviewed at the end of the period.
