A facility does not repaint on one cycle. A reception wall, a washroom ceiling, a plant-room floor and a car-park ramp fail for different reasons and at different speeds. Scheduling by area, and by condition rather than by the calendar, puts the money where the finish is actually failing.
Think area by area
| Area | What wears it | What to consider |
|---|---|---|
| Lobbies and reception | Visitor traffic, scuffs, first impressions | Washable finishes, shades that touch up well, refresh planned around events |
| Corridors | Trolleys, bags, hands, furniture moves | Scrub-resistant finishes; corner guards or a protective dado where wear repeats |
| Workspaces | Light wear, marks from partitions and layout changes | Low-odour products, phased by floor or zone, coordinated with fit-out changes |
| Washrooms and pantries | Humidity, splashes, cleaning chemicals | Moisture-tolerant systems, ventilation, and leaks fixed before painting |
| Plant rooms | Oil, dust, vibration, wash-down, rust on steel | Floor and steel coatings suited to the exposure; thorough surface preparation |
| Car parks and ramps | Tyre traffic, oil, water, worn markings | Floor coating systems suited to vehicles and slip resistance; re-mark lines after coating |
| External walls | Sun, rain, algae, pollution | Weather-resistant exterior systems; crack and joint repair first; safe access at height |
How often to repaint: condition, not calendar
Published repaint cycles for interiors and exteriors are ranges, and they assume good preparation and no moisture problems. Treat them as prompts to inspect, not promises. High-traffic interior zones usually need attention sooner than quiet workspaces, and external walls facing rain and sun age faster than sheltered ones. Decide by inspecting for:
- Fading, chalking or a powdery surface when you rub the wall.
- Peeling, blistering, flaking or cracking, especially in lines along joints.
- Stains, mould or algae, particularly near roof edges, drains and shaded elevations.
- Scuffs and marks that no longer clean off.
- External triggers, such as a rebrand, a client visit or an audit.
Set a review point each year: walk the site with a camera, rank areas by condition and place the worst into the next painting window. Areas in good shape can wait. This fits naturally into an annual maintenance calendar.
Surface preparation and dampness diagnosis
Most early paint failures trace to preparation or moisture, not to the paint. Painting over damp or loose material hides the problem for a season. Before you approve a scope, work through the following.
Before repainting
- Damp patches and peeling: find the source (roof leak, plumbing, external wall crack, rising dampness) and repair it first; see waterproofing before the monsoon.
- Efflorescence and salt deposits: remove them and deal with the moisture path.
- Loose or hollow plaster: cut back and repair; open up and fill cracks.
- Old paint: scrape flaking coats, key glossy surfaces and treat mould before priming.
- Moisture: let surfaces dry, and test where the specification calls for it, before applying primer.
- Steel: remove rust to the level the coating system specifies before applying anti-corrosive primer.
- Access and permits arranged for façade and high-ceiling work, with hot work covered by a permit.
Typical systems in general terms
Layers and product names vary by manufacturer, so treat this as orientation and follow the product data sheet.
- Interior walls and ceilings: primer, putty where needed for a smooth base, then emulsion in a finish level suited to the area.
- Exterior walls: a weather-resistant exterior emulsion or textured coating over sound, repaired plaster with an exterior primer, plus crack treatment and sealant at joints.
- Plant rooms and car parks: epoxy or polyurethane floor coatings suited to load, chemical exposure and slip resistance, applied over a prepared, dry slab.
- Steel and metal: anti-corrosive primer and topcoat systems for structural steel, railings and pipe supports.
- Fire-retardant or intumescent coatings: only where a fire consultant or the design specification calls for them. The type, thickness and rating come from that specification and the manufacturer’s instructions.
Well-known brands such as Asian Paints, Berger and Birla Opus make systems across these categories, and SupplycZar can source them subject to availability. Where a specified brand cannot be fulfilled, we propose suitable alternatives against your specification for your approval before ordering. See painting and coatings for supplies.
Painting in an occupied office
Low-odour and low-VOC interior products are widely available and are usually the practical choice on occupied floors. Confirm on the product data sheet and keep the space ventilated. Beyond product choice, the schedule does most of the work.
- Phase by floor, zone or wing so people move for a short period rather than all at once.
- Keep sanding, solvent-based coatings and floor coatings for nights and weekends.
- Protect furniture, floors and IT equipment. Mask detectors, sprinkler heads and vents only where needed, and put their removal on the handover checklist so nothing stays covered.
- Agree drying and re-entry times against the data sheet, and tell occupants the schedule in writing, including which areas close and when.
Records and the paint specification
Shades can vary slightly between batches, so a paint register pays for itself the first time someone needs a touch-up. For each area, keep:
- Brand, product, finish and shade code, with the tinting system used.
- Batch numbers of the tins used, and sealed leftover tins labelled by area for touch-ups.
- Date painted, contractor, coats applied and the preparation done.
- Photographs before, during and after.
- A touch-up log, so repeated marks in the same place show up as a pattern.
What a paint specification sheet should contain
- Area or surface, with location and approximate area.
- Surface preparation steps and repairs needed beforehand.
- System: primer, putty or filler, coats, finish level and product or approved equal.
- Shade code and tinting system.
- Coats, drying and recoat intervals per the data sheet.
- Odour or VOC requirement, working hours and phasing.
- Warranty, inspection and handover requirements, including snag-list touch-ups.
What to send us for a quote

Frequently asked questions
How often should an office be repainted?
There is no single interval. Base it on inspection: fading, peeling, stains and marks that no longer clean off. High-traffic areas such as corridors and lobbies usually need attention sooner than quiet workspaces.
Why is paint peeling on my wall after repainting?
Usually moisture from a leak, seepage or rising dampness, or poor preparation such as loose plaster or dust under the coat. Find and fix the source, then prepare the surface again before repainting.
What paint is suitable for an occupied office?
Low-odour, low-VOC interior emulsions are the usual choice; check the product data sheet and ventilate. Schedule sanding and heavier work for nights or weekends, and phase the job by zone.
Which coating is used for car park floors and plant rooms?
Epoxy or polyurethane floor coatings are commonly used, chosen for load, chemical exposure and slip resistance and applied over a prepared, dry slab. Confirm the system for your conditions with a consultant or the manufacturer’s data sheet.
