Cleaning painted surfaces with Resene Paint Prep and Housewash  Cleaning painted surfaces with Resene Paint Prep and Housewash

We are regularly asked for advice on cleaning weatherboards. Generally when you are planning to repaint, weatherboards will be dirty and weathered and need cleaning. We recommend washing with Resene Paint Prep and Housewash as waterblasting isn’t as effective and can damage the woodwork.

Many painters and DIY customers believe the best way to prepare a surface for painting is to water-blast and in many situations they are quite right - but not when it comes to joinery and timber weatherboards.

That’s why we developed Resene Paint Prep and Housewash to loosen and shift the chalky surface on UV damaged paint films. The ‘chalk’ is the unbound pigment in paint and must be removed along with other contaminants, including dirt, and moss and mould before painting.

Waterblasting doesn’t shift this chalk (dechalking).
