Side-by-Side Comparison
| Property | Sand & Cement | Monocouche |
|---|---|---|
| Number of coats | 2-3 coats + paint | 1 coat (over scratch coat) |
| Total thickness | 15-20mm | 12-15mm (+ scratch coat) |
| Colour | Grey — needs painting | Through-colour (30+ options) |
| Material cost per m² | £5-10 | £12-18 |
| Total installed cost per m² | £40-60 | £50-75 |
| Application time | 3-5 days (drying between coats) | 1-2 days |
| Cracking risk | Higher (rigid) | Lower (polymer modified) |
| Maintenance | Repaint every 5-8 years | Self-coloured, wash only |
| Repairability | Easy to patch and repaint | Patches may show (colour matching) |
| Lifespan | 20-30 years | 25-40 years |
Pros and Cons
Sand & Cement Render
