Ivy and Creepers on Your Walls: What to Do Before Painting in Toorak

Why creepers and repaints rarely mix

Walk along almost any street in Toorak, Armadale or Kooyong and you will see facades softened by climbing plants: Boston ivy turning crimson across a rendered wall in autumn, English ivy thick over a brick boundary wall, wisteria on a verandah, ornamental grape over a pergola or garage. They are part of the character of the area, and many owners are reluctant to lose them.

When the house needs repainting, though, the creepers become a problem. Paint cannot go on over foliage, and the plant's grip on the wall often leaves damage that has to be repaired before any coating will last. This guide explains what is involved, how to plan the removal, and how to protect the finish if you want the plant to grow back.

Different climbers, different damage

Not all climbers attach to a wall in the same way, and that affects how much work is needed underneath.

Self-clinging creepers

Boston ivy attaches using small adhesive pads on the ends of its tendrils. English ivy climbs using aerial rootlets that push into any crack, joint or porous surface. Both stick directly to the wall, and both leave residue when they are pulled away. On render and painted surfaces, the pads and rootlets often take paint and loose render with them. On older brickwork, English ivy rootlets can work into soft lime mortar joints and loosen them over time.

Twining and supported climbers

Wisteria, jasmine, ornamental grape and climbing roses twine around wires, trellis or downpipes rather than sticking to the wall. They generally leave the surface itself in better condition, but they can trap moisture against the wall, lift gutters and fascias, and work into timber verandah details. Wisteria in particular grows strong, woody stems that can bend downpipes and push against weatherboards.

Plan the removal before you book the painters

Removing a mature creeper is usually a job for a gardener or arborist rather than a painter, especially where stems are thick, the plant reaches the roofline, or work is needed at height. Most painters will price the wall once it is clear, so sort the plant out first.

For self-clinging ivies, the usual approach is to cut the stems at the base and let the plant die back for several weeks. Dead growth releases its grip more easily than living growth, which means less damage when it is pulled away. Pulling a live, established ivy straight off a rendered wall almost always takes render with it.

If your property is in a Heritage Overlay, check with the City of Stonnington before major changes to the facade or garden. A repaint of previously painted surfaces is often fine, but the rules depend on the overlay schedule for your address.

Preparing the wall underneath

Once the growth is off, what is left needs proper preparation before it can be painted.

Removing pads, rootlets and residue

The remnants of tendrils, pads and rootlets are removed by scraping and brushing, then the wall is washed. Some residue is stubborn and takes patience. Painting over it leaves a bumpy, uneven finish and the remnants can eventually lift the new paint.

Repairing render and mortar

Ivy often hides cracked, drummy or missing render. Loose sections are cut back and patched, and cracks are filled with a suitable flexible filler or render repair before painting. On face brick, damaged mortar joints may need repointing. Older homes in Toorak frequently have lime-based mortar and render, and repairs should use compatible materials so the wall can still breathe.

Treating mould and allowing the wall to dry

A wall that has been covered by foliage for years is often damp and stained with mould or algae. It needs to be treated, washed and given time to dry out properly before priming. Painting a damp wall is one of the most reliable ways to get blistering and peeling within a year or two.

If you want the creeper to grow back

Many owners repaint and then let the plant return. That is possible, but it means accepting that a self-clinging ivy will eventually mark the new paint again. A better option is to install a trellis, wire system or stand-off support a short distance from the wall and train a twining climber on that instead. It keeps the green look, lets air circulate behind the plant and makes the next repaint much simpler.

Whatever you choose, keep growth trimmed back from gutters, fascias, window frames and the roofline. That is where climbers cause the most damage and where paint fails first.

Planning a repaint on a creeper-covered home

Our exterior house painting service includes the preparation and repair work that walls need after creepers come off, and our weatherboard and render restoration work covers patching and repairing damaged render. For period properties, our heritage and period repaints service uses breathable systems and compatible repair materials.
