How Long Does Render Last?
The lifespan of render depends on the type used, climate conditions, and maintenance. Here’s a general guideline:
| Render Type | Lifespan | Maintenance Needed? |
| Sand & Cement | 20-30 years | May crack over time, needs repainting every 5–10 years. |
| Monocouche Render | 25-30 years | Minimal maintenance, occasional cleaning. |
| Silicone/Acrylic | 30+ years | Self-cleaning, only needs washing if dirty. |
| Insulated Render (EWI) | 30-40 years | Highly durable, occasional inspection. |
Does Render Need Maintenance?
Yes, but it depends on the render type:
Cleaning – Wash dirt/moss off with a soft brush or pressure washer (low setting).
Repainting – Only required for sand & cement or painted render (every 5–10 years).
Crack Repairs – Small cracks in cement-based render can be filled. Monocouche and silicone renders are more flexible and less prone to cracking.
Inspection – Check for damage or damp patches annually, especially in exposed areas.
If properly applied, modern renders like silicone and insulated render require little to no maintenance beyond occasional cleaning. Would you like advice on choosing a durable render for your home?
