How to paint your weatherboard
DIY, Melbourne
Exterior restoration of a Victorian weatherboard home requiring detailed preparation, repairs and repainting, with a new colour scheme selected to complement the home’s period architecture.
How to Paint a Weatherboard House
Painting a weatherboard house looks straightforward. Prepare the timber, prime it and apply the finish coats.
The challenge is time.
A typical single-fronted weatherboard home might take an experienced exterior painter around 160 hours to prepare and paint properly. For a capable DIY painter, the same job often takes considerably longer.Good preparation matters more than speed. A weatherboard exterior exposed to Melbourne weather needs sound timber, properly prepared surfaces and the right exterior paint system.
Check the exterior first
Before opening a tin of paint, inspect the house carefully.
Look for:
Rotten or damaged weatherboards
Deteriorated window frames and doors
Loose or raised nails
Leaking gutters or downpipes
Rust on metalwork
Cracked gaps and sealants
Peeling or failing paint
Bare or exposed timber
Repair these problems before painting. New paint will not solve underlying timber or moisture issues.
Repair damaged weatherboards
Replace weatherboards that are rotten or badly deteriorated.
Many new weatherboards arrive with a factory or transit primer. This protects the timber during storage and transport but should not be treated as the complete primer system.
Prepare and prime new boards before applying the exterior finish coats.
Remove failing paint
Loose, flaking and unstable paint needs to come off.
Scrape failing coatings back to a sound edge, then sand the surface to smooth the transition between old paint and exposed timber.
Sanding also improves adhesion between the existing surface and the new paint system.
Prime all bare timber before painting.
Fill and seal
Reset protruding nails and fill holes with a suitable exterior filler.
Check gaps around weatherboards, windows, trims and other junctions. Use an exterior-grade flexible sealant suited to timber movement.
Remove items such as house numbers, door furniture and removable fittings where practical. Painting around them usually produces a poorer finish.
Prepare metalwork
Rusty gates, railings, nail heads and metal fittings need separate preparation.
Remove loose rust and failing coatings, then use a suitable metal primer before applying the finish coats.
Painting the weatherboards
Work in manageable sections rather than trying to paint an entire elevation at once.
Brush painting remains effective for weatherboards because it gives good control around board edges, joins and detailed areas.
Work horizontally along the boards and maintain a wet edge to reduce visible joins.
Avoid painting hot surfaces in direct sun. Where possible, work around the house as conditions change during the day.
Always follow the paint manufacturer's temperature, moisture and recoat requirements
Windows, doors and trims
Windows, doors, trims and sills usually need more detailed preparation than broad weatherboard surfaces.
Window sills receive substantial weather exposure, so give particular attention to sanding, priming and coating these areas.
On exterior doors, paint all exposed edges where appropriate to reduce moisture entering the timber.
Decorative trims, fretwork and period features also need careful preparation before painting.
Fences and railings
Timber fences and metal railings often require different products and application methods from the house itself.
Prepare each surface properly and use primers and topcoats designed for the material and its exposure.
How long does it take?
This is the part many DIY projects underestimate.
Exterior painting involves far more than applying paint. Moving ladders, repairing timber, scraping, sanding, filling, sealing, priming and cleaning all take time.
A professional result depends heavily on the preparation completed before the first finish coat goes on.
If you decide to tackle your own weatherboard house, allow plenty of time and do not rush the preparation.
For larger homes, two-storey properties, deteriorated weatherboards or extensive repairs, professional weatherboard painters are usually the more practical option.
