Recommended Solution (Simple and Contractor-Friendly)
For many exterior wall renovation jobs, a colored polyaspartic coating is a strong choice because it protects against weather and UV.
Easy method: apply a colored polyaspartic coating directly by brushing (or rolling).
If the wall has cracks or weak spots, repair first, then coat.
Why Polyaspartic Works Well Outdoors (Plain Words)
- UV stability: helps keep color and reduces yellowing over time
- Weather resistance: handles rain and temperature changes
- Strong film: helps protect the wall surface and reduce future maintenance
For example, ZDS1462AB is described with strong flexibility, low VOC, temperature resistance, and UV aging performance (simulating over 10 years with virtually no yellowing).
Surface Prep (Do These 4 Things)
Good prep is the difference between “looks good for 6 months” and “lasts much longer”.
- Clean: remove dust, chalking, oil, and loose paint
- Repair: fill cracks and weak spots
- Create grip: light sanding where needed (especially glossy paint)
- Dry check: do not coat over standing water

Common Mistakes to Avoid
