How to Use This Rendering Calculator
Step 1: Measure the Wall Height
Measure from the ground (or damp proof course) up to the eaves. A single-storey UK property is typically 2.4m, while a two-storey house is around 5m. If your walls have different heights, calculate each separately.
Step 2: Measure the Wall Width
Measure the horizontal length of the wall face you want to render. If all four walls are different widths, use an average or calculate each wall separately and add the totals together.
Step 3: Choose Your Render Type
Sand/cement is the cheapest option and suits most budgets, but it needs repainting regularly. Monocouche is a popular mid-range choice with built-in colour. Silicone render is the premium option — it's self-cleaning, flexible and lasts the longest, making it ideal for exposed properties.
Step 4: Select the Number of Coats
Two coats is standard for most render types. Sand/cement typically uses a scratch coat plus a finishing coat. Monocouche is designed as a single-coat system but some installers apply two for extra durability. Adding a third coat increases protection but also increases cost proportionally.
