How Much Silicone Render Do I Need?

Calculate your area in 3 steps:

Measure wall height (ground to eaves)
Measure total wall length (add all sides)
Deduct 15% for windows/doors

Formula:
(Height × Length) × 0.85 = Rendering Area

*Example for 3-bed semi:*

Wall height: 6m
Total wall length: 25m
Calculation: (6 × 25) × 0.85 = 127.5m²
