How to Paint a Solid-Timber Front Door Properly

By Jen — painter, Melbourne VIC.

Every painting blog tells you to leave the front door on its hinges. Convenient — sure. Quick — sure. But the finish? It will show every brush mark across every panel because you can’t get the brush horizontal across the bottom rails of a hung door. Take it off the hinges. Lay it flat. Paint both sides properly. Re-hang it the next day. The job goes from “alright I guess” to “wow when did you do that”.

Aussie front doors have a specific UV problem. A west-facing door in Melbourne, Sydney, Brisbane or Perth gets hit by 4–6 hours of direct sun in summer. Old-school oil-based enamels — the ones your grandfather used — yellow and chalk in 12–18 months under that exposure. The fix is a UV-stable acrylic enamel. Dulux Aquanamel, Wattyl Aqua-Sheen, or Taubmans Tradex All Purpose Enamel are all engineered for this. They stay white when they were white, they don’t yellow, and they don’t chalk into your hand when you knock on the door three years later.

For a stained or oiled timber door (Cedar, Tassie Oak, Merbau front doors are common), the analog is Cabot’s Cabothane Water Based Exterior or Sikkens Cetol — same UV stability, but clear with timber pigments rather than opaque colour. Same prep, same technique, same “off the hinges” rule.

The job takes a long weekend if you do it properly. Friday evening: take the door off, clean and sand. Saturday morning: prime first coat. Saturday afternoon: prime second coat. Sunday morning: enamel first coat. Sunday afternoon: enamel second coat. Monday morning: re-hang. The door’s off the house for three nights, so plan for a temporary tarp or a sheet of ply screwed across the frame from inside if you live somewhere it might get cold or wet.

What you’ll need

• Two trestles or sawhorses, plus a couple of dust sheets
• A drill/driver, plus an offcut of timber to chock the door open
• Sandpaper: 80 grit (if heavily flaked), 180 grit, 240 grit
• Selleys Sugar Soap and methylated spirits
• Selleys No More Gaps for any cracks at panel joints
• Dulux 1Step Primer Sealer Undercoat (water-based) — $55 for 1L
• Dulux Aquanamel topcoat in your colour, semi-gloss or gloss — $90 for 1L
• 50 mm and 25 mm angled sash brushes — Purdy XL or Wooster
• 4-inch high-density foam roller and tray

Step 1: Take the door off the hinges

Open the door. Chock it with a wedge so it can’t swing while you work. Use a hammer and an old screwdriver to tap up the hinge pins from below — most modern Aussie hinge pins lift straight out. If they’re rusted in, a bit of WD-40 and patience. With the pins out, lift the door off the hinges (it’s heavy — get a hand for this). Carry it to the trestles.

Step 2: Remove all the hardware

Off comes the door knob, deadlock, peephole, kick plate, weather seal — anything that can be unscrewed. Bag and label each piece. Painting around hardware looks like a rushed job; painting with hardware off looks like a refurb. Same effort either way.

Step 3: Strip or sand the existing finish

If the door is painted and the paint is intact, scuff-sand the entire surface with 180 grit. If the paint is flaking or cracking, you need to strip the bad sections back to bare timber with 80 grit and feather the edges, then build back up. If the door is stained timber and you’re going to paint, sand back to bare timber — paint won’t bond reliably to timber oil. Wear a mask, especially if the original paint is pre-1970 (lead risk in Aussie doors built before then).

Step 4: Fill any cracks at panel joints

Solid-timber doors have a frame-and-panel construction, and the panels move slightly with seasonal humidity. Where the panel meets the frame, a hairline crack often opens up. Squeeze a bead of Selleys No More Gaps (water-based, paintable) into the crack, smooth with a wet finger, wipe off excess. Let it skin over for 30 minutes before painting.

Step 5: Wash, dry, metho

Sugar soap wash, clean water rinse, microfibre dry, methylated spirits wipe. The metho takes off any remaining oil or wax — critical on doors that have been Mr Sheened or oiled by previous owners.

Step 6: Prime — both sides

This is where most people cut corners. Prime BOTH sides of the door, plus the top edge and bottom edge. Why? Moisture enters timber doors through the unsealed top and bottom edges, and unprimed timber on one side wicks moisture into the painted face, lifting the topcoat. Prime everything. Foam roller for flats, brush for the panel reveals and edges. Two coats of primer, sanded with 240 grit between coats.

Step 7: First enamel coat — work with the grain, top to bottom

Aquanamel paints on like cream. Pour into a kettle, dip the brush, beat off the excess. For a standard 6-panel door: paint the panels first (their reveals with the 25 mm brush, then the flat with the foam roller), then the horizontal rails (top, middle, middle, bottom — 4 horizontals on a 6-panel), then the vertical stiles (sides and the central stile). Always finish your stroke off the wet edge — never start in the middle of a section.

Step 8: Don’t forget the door edges

The hinge edge and lock edge of the door are visible when the door is open and they take heavy use. Paint them in the same colour. The top edge — sealed but doesn’t need to be neat. Bottom edge — same. The colour of these hidden edges matters less than the seal; the seal stops moisture wicking in.

Step 9: Second enamel coat after 4–6 hours

Light 240-grit sand, tack-cloth wipe, second coat. Same panel-rail-stile order. The second coat is the show coat — slow, careful, evenly loaded brush. Foam roller for flats keeps brush marks out of the panel faces.

Step 9a: Re-paint the architrave and door frame too

This is the bit people skip and regret. The frame and architrave around the door also get UV exposure, and they’re often painted in a different (older) coat that now looks dull next to the freshly painted door. Spend an extra hour cutting in the door frame and the inside-facing architrave with the same Aquanamel. Same prep — sugar soap, light sand, two coats. It transforms the entrance more than the door alone.

Step 9b: Weather seals and door bottoms

Check the bottom rubber seal while the door is off. If it’s perished, brittle, or has gaps, replace it now — Raven RP78 or Lockwood weather seal kits, $30–$50, available from Bunnings or Lockwood specialty. Self-adhesive perimeter seals (Raven RP8) for the door jamb stop draughts and seal cooled air in summer. Five-minute fitment while you’re already in there.

Step 10: Re-hang after 24 hours, full cure 7 days

The enamel is touch-dry in 90 minutes but it’ll mark if you put the door back on hinges and bang it shut on day one. Wait 24 hours, re-hang, refit hardware. Don’t slam it for a week. Full UV-stable cure takes about 7 days under typical Aussie conditions — cooler weather extends this to 14 days. Park the kids’ bikes elsewhere.

Step 11: Colour considerations for west-facing doors

Dark colours absorb more UV and heat — a black or deep navy west-facing solid timber door can hit 65°C surface temperature on a Perth summer afternoon. That’s enough to warp solid timber if the door isn’t well-sealed all sides, and it accelerates UV degradation of even UV-stable acrylics. If you’re going dark on a west-facing door, factor in slightly more frequent recoats (3–4 years vs 5–7 for lighter colours) and consider a Resene Cool Colour or Dulux Heat Reflective Roof colour matched in a door enamel.

Lighter colours — soft greens, mid-greys, off-whites — are more forgiving. Dulux Natural White, Resene Half Spanish White, or Wattyl Hog Bristle are all reliable choices that age gracefully on Aussie front doors.

Step 12: Maintenance schedule

A properly painted solid-timber front door with a UV-stable acrylic enamel needs: a sugar-soap wash twice a year (more often if it’s coastal — salt accelerates breakdown), a touch-up of any chips or knocks within 6 months of damage (don’t let bare timber stay exposed), and a full recoat every 5–7 years on a south-facing door, every 3–4 on a west-facing one. Recoat is just a single fresh enamel coat over a light scuff sand — not a full strip. Stays cheap if you keep up with it.

The Jen rule

Hinges off, edges sealed, both sides painted. Those three rules separate a 5-year-perfect front door from one that looks tired in 18 months. The west-facing UV is what kills cheap finishes — Aquanamel handles it because the resin is engineered for outdoor exposure, but only if the substrate is sealed all the way around. Cut the corner, get the cracking.
