Our painter wouldn't start until we'd cleaned the exterior properly
Wash NZ did a thorough pre-paint wash. The finish came out smooth and lasting.

FAQs
Pre-Paint House Washing questions.
Something else on your mind? Call 021 66 88 45 or send us a message.
What makes a pre-paint wash different from a standard house wash?
A pre-paint wash focuses on surface preparation: removing mould, grime and oxidised “chalk,” and ensuring the surface is clean, sound, and ready for primer and topcoats. It's a more thorough, painter-friendly process.
Do you remove oxidisation/chalking so the new paint will adhere?
Yes. We carry out mould and chalk removal using painter-safe detergents and controlled soft-wash techniques, followed by a thorough rinse, so primers and topcoats can bond properly.
Will the exterior be fully dry and ready for the painter the same day?
Typically yes. We aim for a paint-ready dry finish on the same day (weather dependent). Your painter can then prime/paint as soon as moisture levels and conditions are suitable.
Is the wash safe for older paint and different cladding types?
It is. We use a low-pressure soft-wash approach suited to weatherboards, plaster, brick, and metal claddings, adjusting technique to protect delicate or ageing coatings while still achieving a clean, stable surface.
I'm changing to a darker/lighter colour. Do you prep any differently?
We tailor the clean for colour-change prep by paying extra attention to high-exposure areas, streaking, and residual chalk so the new colour lays evenly and the finish looks consistent.
How far in advance of painting should I book the wash?
Ideally 2–5 days before painting to allow for any weather rescheduling and to ensure a dry, dust-free surface on paint day. We can coordinate timing directly with your painter if you prefer.
