If your building’s exterior looks dull and dirty, before considering painting the render, consider a more cost-effective and durable solution: render cleaning. While painting can offer immediate improvement, there are drawbacks to bear in mind.
Painting the render can be expensive, involving compliance with health and safety regulations, scaffolding, and finding an exact colour match. However, without proper cleaning, it’s merely a temporary fix.
Through-coloured render needs to breathe. Painting over it traps moisture, leading to dampness, flaking, and peeling. Moss, algae, and lichens will regrow through the surface, requiring costly removal.
