ACP panel loose or coming off in Gurgaon: why cladding fails and the fix

ACP cladding is the default shop-front and facade finish across Gurugram's markets, from MG Road showrooms to the commercial strips of Sohna Road and Noida's Sector 18. It's light, flat and comes in any colour. But a panel that starts flapping in a dust storm or peels away above a shop entrance is a real hazard to people below, and a sign that something behind it has failed.

Why ACP comes loose

Panels stuck on with adhesive or tape, not a frame

The cheapest way to clad a front is to glue ACP straight onto plaster, or onto a frame using double-sided tape alone. In a 45°C summer the adhesive softens, and rain gets behind it in the monsoon. The bond fails edge-first, and the panel starts to lift. This is the most common cause.

Rusted MS frame behind the panels

Proper ACP is fixed to a sub-frame, often of MS (mild steel) tube or aluminium. An unpainted or poorly painted MS frame rusts behind the cladding where nobody sees it, until rivets pull out of the rusted section.

Rivets or screws pulled out

Rivets set too close to the panel edge, wrong-size rivets or too few fixings let panels work loose with wind and thermal movement.

No expansion gaps: panels buckle

Aluminium expands in heat. Panels butted tight against each other with no gap bow outward on a summer afternoon, which pulls fixings and breaks the bond along joints.

Failed joint sealant and water ingress

The silicone between panels keeps water out. Once it cracks, water gets behind the panels, rusts the frame and attacks any adhesive.

Wind load at corners and parapets

Corners, top edges and high panels take the strongest wind. A dust storm finds the weakest fixing there first.

What you can check without climbing

• From the ground, look along the facade for panel edges that sit proud of their neighbours, bulges or gaps at joints.
• Look for rust stains running down from joints or fixings.
• On a windy day, listen for rattling or flapping, and note which panel.
• Don't climb up to push or tape a loose panel. Facade work at height needs proper access and safety gear.

Repair or re-clad?

If only a few panels are loose and the frame behind them is sound, they can be re-fixed with correct rivets, gaps and sealant. If the panels were glued to plaster with no frame, or the MS frame behind has rusted widely, the lasting fix is to strip and re-clad with ACP cladding on a properly protected sub-frame, with expansion gaps and sealed joints. Many shop owners use the opportunity to rethink the front: structural glazing for a glass face, or aluminium louvers for ventilation and a screen over AC units. The ACP cladding shop front guide explains panel thickness and fire-rated core options, and the ACP cladding price guide covers what changes the cost. Some commercial complexes and markets have facade rules, so check with the building management before re-cladding.

How FabWise handles a loose ACP panel

Send photos of the whole facade, close-ups of the loose panels and any rust stains, and the floor level, on WhatsApp. If we need to inspect it, the site visit is ₹99, adjusted against the bill if you go ahead. ACP work is quoted after the visit; there's no published rate for it.

Preventing it next time

1. Fix ACP mechanically to a sub-frame, not with adhesive or tape alone.
2. Use aluminium or properly primed and painted MS for the frame.
3. Leave expansion gaps between panels and seal them with a weather sealant.
4. Check the joints and fixings after each monsoon and dust-storm season, especially at corners and the top edge.
