Painting a brick exterior wall in Rotterdam — does it need sealing first, and what's the total cost?

by AstraNL Community▲ 01 views

We have a 1970s brick house in Rotterdam with bare, porous exterior brickwork (roughly 60m2). It's never been painted or sealed. We want to freshen it up but I've heard conflicting advice: some say you must seal brick first, others say just prime and paint. What's actually required, and how much more expensive does sealing make it?

Dutch brick typically needs proper prep before painting. For bare, porous 1970s brick, a moisture-blocking primer or penetrating sealer is strongly recommended (not optional) to prevent water ingress and paint failure — especially in Rotterdam's damp climate. Expect €800–€1,400 for sealing alone, then €1,200–€2,000 for primer and exterior paint on 60m2. Total: roughly €2,000–€3,400. Cost varies by: brick condition, existing damage, paint quality (premium acrylics last 10+ years), and scaffolding needs. No permit required for a standard repaint.
