How to Maintain and Protect Venetian Plaster Walls

Venetian plaster is more than just a decorative finish — it’s a surface that combines natural beauty with strength. With the right care, it can last for decades, developing character and depth that paint or wallpaper simply can’t match.

The good news is maintenance is easier than many people expect. From sealing and cleaning to knowing what products to avoid, a few simple steps will keep Venetian plaster walls looking fresh and refined.

In this guide, we’ll walk through how to protect your plaster, keep it clean, and make sure it continues to enhance your home or project for years to come.

Here’s a refined version of the section with those products included:

Why Protection Matters

Finishes like Riflesso, Volare, and Infinito are all lime-based. This gives them their natural beauty, breathability, and depth of colour — but it also means they need the right care to stay looking their best.

• Sealing adds durability – applying a protective sealer such as Rain Protex helps resist stains, splashes, and dirt build-up.

• Helps in humid areas – kitchens, bathrooms, and high-traffic zones benefit most from added protection.

• Preserves the finish – whether it’s a high-gloss Riflesso wall or a softer Volare or Infinito texture, sealing keeps the look consistent over time.

Protection doesn’t change the finish — it simply locks in the beauty and ensures it lasts for years.

Sealing and Protective Options

The right protection depends on the finish you’re working with. Each product responds best to a specific sealer:

• Riflesso (Polished Plaster)

  • For high-shine, mirror-like finishes, apply Cera (wax).

  • This enhances the depth of polish and provides a protective layer without dulling the surface.

• Volare (Marmorino Medium)

  • Works in satin or semi-polished finishes.

  • Protect with Rain Protex, especially in bathrooms, kitchens, or humid spaces.

• Infinito (Textured Lime Finish)

  • More absorbent due to its surface movement.

  • Seal with Rain Protex to reduce dirt absorption and make cleaning easier.

• Microcement (if used in the same project)

  • Cement-based, not lime-based.

  • Requires a polyurethane topcoat for waterproofing — essential in showers, floors, and countertops.

👉 General rule: Cera for polished finishes, Rain Protex for satin/textured lime finishes, polyurethane for Microcement.
