Chalking
The surface leaves white powder on your hand - a sign that the resin has started to break down under UV radiation.
When Is It Time to Repaint
Before wear becomes damage
Typical paint lifespan
| System | Indicative life |
|---|---|
| Standard acrylic | 5–7 years |
| Elastomeric | 8–12 years |
| Silicone | 10–15 years |
Lifespan is affected by sun exposure, coastal environment, preparation quality, and application thickness. Repainting should be scheduled near the end of the expected life - not after failure.
Signs that it's time
The right time for repainting isn't when the facade is "ruined" - it's when the first signs of wear appear, before the damage becomes structural.
Micro-cracks
Fine cracks appear across large areas - the film is gradually losing its elasticity.
Dullness & fading
The colour loses its vibrancy and gloss - an indication of external film degradation.
Localised peeling
Small delaminations at specific points - the beginning of a process that will spread if not addressed.
What happens if you wait too long
If repainting is delayed, moisture penetrates deeper, cracks widen, extensive plaster repair is needed - and the cost increases significantly.
The difference between preventive and delayed intervention can multiply the cost, because substrate repair costs more than the paint itself.
Early intervention means painting - delayed intervention means restoration plus painting.
Preventive maintenance vs restoration
Preventive repainting requires fewer repairs, keeps the substrate stable, and lowers the total lifecycle cost. Delayed intervention always includes additional restoration work.
Preventive intervention always costs less than restoration - the right timing reduces cost and protects the building.
How to plan properly
The decision to repaint shouldn't be based on aesthetics alone. A proper approach involves four steps.
① Periodic inspection
Visual facade check at least once a year - ideally after winter.
② Wear assessment
Identify chalking, cracks, peeling - categorise the degree of wear.
③ Remaining life estimate
How many more years can the existing system last without reaching failure?
④ Budget planning
Include repainting in the building's maintenance plan so it's not an "emergency" expense.
