Exterior Flagship Series
Leyton®
Exterior flagship · weather-durable
Goes straight over four substrate types: existing tiles, old coatings, stone-texture render and brick. Skip scaffolding and stripping time, and stay weather- and UV-resistant.
What it is
Coat over the old surface instead of tearing it off
A two-component water-based porcelain enamel that cures into a weather-durable porcelain film with strong adhesion to common existing facade substrates. Flexible and crack-resistant, applied by standard procedure directly over a cleaned old finish.
Pack Size6 kg total (ratio A:B = 1:11)

Applications
Where to use it, where not to
Suitable for
- Building facades
- Tile facades renewal
- Coated facade refurbishment
- Stone-texture facade renewal
- Brick wall restoration
- Steel staircase coating
Not suitable for

Application
Substrate → mixing → coating → curing
Substrate requirements
Application steps
- Mix parts A and B at the factory ratio (A:B = 1:11), stirring for at least 3 minutes
- A penetrating primer coat is recommended first, to seal the substrate and improve adhesion
- Apply two coats; recoat once the previous coat is touch-dry
- Apply at 5-35 °C and RH below 80%; avoid rain, strong wind and sandstorm conditions

How it differs
Different from conventional coating systems
| Film formation | Water evaporation, particle coalescence | A/B cross-linking cure |
| Film structure | Thermoplastic, softens with heat | Cross-linked, dense, porcelain-like |
| Water Resistance | Typical product level | 300 h, no abnormality◊ |
