Polished Plaster Maintenance: Tips from the Experts

Polished plaster is one of the few interior finishes that rewards both close inspection and long-term use. Hand-applied by skilled artisans, it brings natural texture, tonal depth, and a quiet sense of luxury to residential and commercial interiors alike.

But while these surfaces are built to last, they’re not invincible. The secret to maintaining their elegance is simple: thoughtful care and the occasional expert check-in.

At Ambitec, we believe great design doesn’t stop once the plaster dries. This guide brings together our expert advice on preserving the integrity of your walls, so they continue to reflect your space, style and standards for years to come.

Why Care Matters

Polished plaster isn’t precious, but it is particular. Like timber or natural stone, it will hold up beautifully when respected and maintained with intention. Routine care not only prevents premature wear, it helps preserve the subtle tonal shifts and handcrafted qualities that make each surface unique.

In high-traffic commercial spaces, a well-maintained finish is part of the customer experience. In private interiors, it’s part of the everyday joy of living with natural materials.

Everyday Maintenance

The good news is that daily upkeep is uncomplicated. Most polished plaster finishes can be kept looking their best with minimal effort:

• Dust regularly with a soft microfibre cloth to maintain a clean, even surface
• For light marks, a damp cloth and water will usually suffice
• Avoid abrasive sponges or harsh cleaning agents, which can compromise the finish
• Where needed, use a pH-neutral cleaner, applied sparingly and spot-tested in an inconspicuous area

Like the finish itself, the right care approach is subtle and considered.

High-touch Maintenance

In high-traffic commercial settings (reception counters; apartment lobbies) or busy home spaces like hallways and entranceways, some wear is inevitable.

Here’s how to address it:

• Gently rub scuffs with a damp cloth in a circular motion; avoid scrubbing
• For light scratches, gently scuff in a circular motion with a 320Grit paper (avoid if sealed)
• For larger scratches or repairs, contact Ambitec for expert touch-up guidance or to book in a visit

We’re always happy to advise. Often, minor issues can be resolved quickly – or prevented altogether with the right approach.

Design for Durability

A few simple precautions can extend the life of your finish without compromising aesthetics:

• Incorporate skirting details to mitigate wear and tear from vacuuming and mopping
• In busy public settings, consider design-led deterrents like feature shelving or integrated signage that subtly redirects touch
• Include dado wall panelling, stone or timber panelling along the lower high-touch sections of your wall
• Use felt pads or buffers on furniture that comes into contact with walls
  

As with all good design, it’s about balance – protecting the finish while letting it live in the space naturally.

Commercial vs. residential: a slightly different rhythm

While the care fundamentals are the same, commercial spaces benefit from a more proactive approach – regular inspections, occasional resealing, and early intervention in high-touch zones.

In residential settings, maintenance is usually lighter. A gentle cleaning routine and a few simple habits (like avoiding contact from furniture or bags) are enough to preserve the finish for years to come.

Whether your space is public-facing or private, we can advise on a care plan that fits the pace of your environment

Resealing, Refreshing, and Long-term Support

Over time, your polished plaster may naturally evolve – deepening in tone, softening in sheen, or developing subtle surface character. These changes are part of the beauty of natural finishes.

Still, if your surface begins to feel tired or overworked, our team can assist with:

• Professional resealing to renew protection
• Sheen restoration for polished finishes
• Re-blending or partial resurfacing in high-contact areas

As every Ambitec finish is handcrafted, every solution is custom. We treat your wall not as a product, but as part of your architecture – and your story.

An Ongoing Partnership in Surface Design

Great finishes are an investment – in texture, in atmosphere, and in experience. They deserve aftercare that’s as thoughtful as their application.

At Ambitec, we’re proud to be more than makers. We’re long-term collaborators in the life of your space, offering guidance, technical support, and creative solutions well beyond installation day.
