ACP and facade cleaning for shops in Kollam: what it costs to skip
The short answer
An ACP shopfront in Kollam should be cleaned about twice a year, and more on a main road or near the coast. Aluminium composite panels have a coated finish that dulls under salt, monsoon grime and traffic film, and the damage from cleaning them badly is permanent — abrasive pads, strong solvents and high-pressure washing all take the coating off, after which the panel can only be replaced. A correct clean is pH-neutral, low pressure, soft, and worked top to bottom.

What a coastal climate does to a shopfront
Aluminium composite panel is two thin aluminium skins over a core, with a coated finish — usually PVDF or polyester — doing all the work of looking good and resisting weather. That coating is a few microns thick, and everything about cleaning ACP correctly follows from that one fact.
- Salt in the air settles and holds moisture against the panel and, more importantly, against the joints and fixings.
- Monsoon rain carries dust down the face and leaves streaking, which sets into a hard film over a season.
- Traffic film on a main road — exhaust, brake dust, oil — is greasy and binds the rest of it in place.
- Algae and black staining in the shaded and permanently damp sections, which is a Kerala speciality.
- UV chalking: the coating oxidises to a fine powder that makes the panel look permanently dull, and past a certain point cannot be restored.
The commercial cost is that a dull, streaked frontage reads as a business that is not doing well, on a street where the shop next door is clean. That is a slow, invisible cost and it is the actual reason to keep a facade clean.
How often
| Situation | Interval |
|---|---|
| Main road frontage — Karunagappally, Kayamkulam, Kottarakkara | Every 4–6 months |
| Coastal locations — Chavara, Thodiyoor and the strip | Every 4–6 months, with the fixings checked |
| Quieter street, inland | Twice a year |
| After the south-west monsoon | Always — this is the one clean not to skip |
| Before a festival season or a reopening | As needed, and worth booking ahead |
The post-monsoon clean is the one that matters most, because that is when a season of streaking and algae is still soft enough to come off without aggressive methods. Left until it hardens, the same job needs stronger treatment on a coating that has already been weathered.
What ruins a panel permanently
Every item here is something we have been called out to after somebody else did it, and none of them can be undone by cleaning afterwards.
- ABRASIVE PADS, scouring powder or a wire brush. These scratch the coating off. The marks are permanent and they catch dirt faster afterwards.
- HIGH-PRESSURE WASHING. It drives water behind the panels and into the joints and fixings, and at close range it strips the coating outright.
- STRONG SOLVENTS, thinner, acids or alkaline degreasers. They attack the coating and the sealant in the joints.
- CLEANING IN DIRECT SUN. The solution dries on the panel before it is rinsed, which leaves streaks that are then harder to remove than the dirt was.
- BOTTOM-TO-TOP. Dirty water runs down over clean panels and dries into streaks — it is a technique detail and it is the difference between a good result and a patchy one.
Facade work at height is regulated work with real fall risk, and a shopfront is usually above a public footpath. Ladders propped against a panel are how both the panel and the person get damaged. It needs proper access equipment and someone insured to be on it.
What a professional clean involves
- Survey the frontage: panel type and condition, joints and sealant, fixings, and what access the site allows.
- Test on a small, inconspicuous area first, especially on an older or already-chalked panel.
- Rinse down at low pressure to take the loose material off before anything is touched.
- Apply a pH-neutral cleaner and give it the dwell time to work, rather than substituting pressure for patience.
- Work by hand with soft brushes and microfibre, top to bottom, panel by panel.
- Rinse thoroughly with clean water and dry off to prevent streaking.
- Report on what was found — perished sealant, loose fixings, corrosion at the joints — which is the part of the job an owner never sees for themselves.
