How long it takes to paint a house in Perth

People plan around a painting job — moving furniture back, having family stay, getting a house on the market. So the honest answer matters more than the optimistic one.

These are working days on site, for a typical crew of two to three.

Why preparation dominates the estimate

On a sound, modern house, preparation is roughly a third of the time. On a 1970s exterior with failing coatings and forty years of timber movement, it is well over half. The painting itself is the fast part — it is the washing, scraping, filling, sanding, caulking and priming that sets the schedule.

This is also why a quote with a much shorter timeframe is usually not more efficient. It is doing less.

The four things that push it out

**Weather.** Perth gives you a long, reliable painting season and then takes it back in July. Exterior work needs the surface dry, and after winter rain a rendered wall can need a day or two before it is dry enough to coat. Wind matters too — spraying stops well before painting does.

**Discovery.** Rotten fascia behind the paint, render that sounds drummy when tapped, rust under a coating on steel. None of it is visible when the quote is written, and all of it has to be dealt with before the topcoat.

**Colour changes.** A dark colour over light, or a strong colour like a deep red or yellow, can need an extra coat and sometimes a tinted primer. Deciding this mid-job costs a day.

**Occupancy.** An occupied house is slower than an empty one, and it is nobody's fault. Furniture gets moved and moved back, rooms are done in sequence so the household still functions, and set-up and pack-down happen every single day rather than once.

Drying is not the same as curing

Most water-based products are touch dry in under an hour and recoatable in two to four. That is what sets the day-to-day pace. But full cure — the point where the film has reached its final hardness — takes considerably longer, often two to four weeks.

That matters practically: do not scrub a freshly painted wall, do not push furniture hard against skirtings, and be gentle with new enamel on doors for the first fortnight. The job is finished long before the paint is.

What a realistic programme looks like

A well-run exterior repaint on a single-storey rendered house usually runs: one day wash and dry, one to two days preparation and repair, one day masking and priming, two days coating, half a day detail and clean-up. Six days, and the customer sees visible progress on only three of them.

That gap between "days on site" and "days that look like painting" is the single most common source of impatience on a job, and it is worth knowing about in advance.
