Durability depends on the whole system
The decorative topcoat is only one component. Preparation, reinforcement, detailing, substrate movement, exposure, drainage and maintenance all influence performance.
What helps it age well
- Correct preparation and compatible materials
- Sound beads, seals and weathering details
- Application within suitable weather conditions
- Prompt attention to leaks or building movement
- Gentle cleaning rather than aggressive pressure washing
Manufacturer warranties and expected service life should be read alongside the actual system specification and conditions, not treated as a guarantee that every wall will remain visually unchanged.
