When to stain a deck in Christchurch, and when not to

The rule: spring or autumn, not midsummer

It feels logical to stain the deck on the hottest, sunniest day of the year. It's actually the worst day for it. Direct high summer sun flashes the stain off at the surface before it can soak into the timber: you get inconsistent drying, lap marks where wet edges dried at different speeds, and a patchy finish that wears unevenly. The General's rule: spring or autumn, when it's warm and settled but the sun isn't at full punch.

In practice that means October–November or March–April. What you're looking for:

• A settled stretch: dry the day before, the day of, and ideally a day or two after.
• Dry timber. After rain, decking needs a few clear days before it'll take stain properly.
• Shoulder-season mornings can carry dew and the odd frost, so let the deck dry off and start mid-morning.

Timing is half the job: prep is the other half

The best-timed stain still fails over dirt, mould or flaking old coating. The sequence that lasts: waterblast the grime and loose coating off, let the timber dry out fully, sand the rough patches, fix anything loose, then coat. That order is exactly how a professional fence and deck staining job runs.

How long will it last?

A well-timed, well-prepped stain or oil typically goes two to four years. Decks in full sun wear fastest and appreciate a re-oil at the shorter end; shaded fences stretch longer. Book the re-coat when water stops beading on the surface. That's the timber telling you it's thirsty.
