San Diego Venetian Plastering, Limewashing, and Roman Clay

Originating in ancient Italy, Venetian plaster—also called Italian plaster—gained prominence in the United States in the 1990s. During that time, it was a very costly finish to produce. Today, although it is still a labor-intensive process to install, the cost of the product has come down considerably. This makes it within reach of the average homeowner.

Venetian plaster is a unique finish that no paint technique can mimic; it produces a warmth and subtlety that is unmatched. This is partly due to the fact that Venetian plaster is hand-troweled on and then polished, creating a smooth, lustrous finish. When it is applied in thin layers, the ground up marble dust in the plaster creates translucency and gives the appearance of depth and “movement.” Viewed from different angles, Venetian plaster gives a glossy, mirror-like finish.

Venetian plaster is a unique finish that cannot be mimicked with any other product; it produces a warmth and richness that is unmatched. This is partly because, unlike paint, Venetian plaster is hand-troweled and then polished, creating a smooth, lustrous finish. Applied in thin layers, the ground-up marble dust in the plaster creates translucency and gives the appearance of depth and “movement.” Viewed from different angles, Venetian plaster can produce a glossy, mirror-like finish. There are also more matte-finish, rustic Venetian plasters that lend themselves well to classic Spanish and Italianate architecture.

For the past 8 years, we’ve also provided Tadelakt finishes for shower interiors, or other wet areas. Tadelakt is a smooth, waterproof plaster finish that is a great alternative to stone and tile. It provides a lustrous, modern warmth that is both unique and durable.

Today’s Venetian plasters offer durability and maintenance not seen in traditional Venetian plasters. In many cases, damage or blemishes on finished walls can be sanded, buffed, or replastered, without the need to re-do entire walls. Venetian plaster is also a very sustainable and healthful product, as it is nontoxic and emits zero VOCs (volatile organic compounds). It is also naturally mold and mildew-resistant.

Technique and style in Venetian plaster application is very important for rendering a high quality, professional finish. For this reason, it is important that the installer has years of experience. Too often, when an unqualified person applies the plaster, the results are unsatisfactory. Septembre Studio has been applying Venetian plaster in homes, offices, and businesses for over 20 years.

General

What is Venetian plaster?

Venetian plaster is a natural, lime-based wall finish that creates a smooth, polished stone-like effect. It’s known for its depth, movement, and elegant sheen. Originating from Italy, it’s breathable, durable, and eco-friendly.

What is Roman Clay?

Roman Clay is a natural plaster-like wall finish made from clay, minerals, and pigments. It provides a soft, matte, suede-like appearance that adds warmth and texture to any space. It’s VOC-free and environmentally friendly.

How are Venetian plaster and Roman Clay different?

While both are natural and hand-applied wall finishes, Venetian plaster has a polished, sometimes glossy finish that mimics marble or stone. Roman Clay has a more matte, velvety texture with a softer, modern look. The choice depends on the aesthetic you want.

Are these finishes safe and eco-friendly?

Yes. Both Venetian plaster and Roman Clay are non-toxic, low or zero VOC, and made from natural materials, making them safe for homes, businesses, and even nurseries.

Installation & Maintenance

Where can Venetian plaster and Roman Clay be applied?

They can be applied to most interior walls and ceilings. Venetian plaster is also suitable for bathrooms and other moisture-prone areas when properly sealed. Roman Clay is ideal for feature walls, bedrooms, and living spaces.

How long does the application process take?

Depending on the size and complexity of the space, most projects take 2 to 5 days, including prep and drying time. Custom finishes or larger projects may take longer.

Do I need to prime the wall first?

Yes. Proper surface preparation is crucial. We typically apply a primer or base coat to ensure strong adhesion and a smooth, long-lasting finish.

How durable are these finishes?

Venetian plaster is extremely durable and can last for decades with minimal maintenance. Roman Clay is also durable but slightly softer and more prone to surface scuffs—though these can be touched up easily.

Is sealing necessary?

Venetian plaster often benefits from a wax or sealant to enhance sheen and water resistance, especially in kitchens and bathrooms. Roman Clay is typically left unsealed for its natural matte appearance but can be sealed if desired for extra protection.

Design & Customization

Can I choose the color and texture?

Absolutely. We offer a wide range of custom colors, sheens, and textures to match your design goals—from modern and minimal to rich and old-world finishes.

Will every wall look the same?

No, and that’s the beauty of it. Both Venetian plaster and Roman Clay are hand-applied, meaning each wall will have unique movement, variation, and character.

Cost & Value

Is Venetian plaster or Roman Clay expensive?

A: These are considered premium finishes, but they offer long-term value. Unlike paint, they don’t need to be redone frequently and can elevate the aesthetic and value of a space significantly.

Does it increase property value?

Yes. High-end wall finishes like Venetian plaster and Roman Clay are seen as luxury upgrades and can increase your home’s resale appeal and value.

Aftercare

How do I clean Venetian plaster or Roman Clay walls?

Use a soft, dry or slightly damp cloth. Avoid harsh chemicals or abrasive sponges. For sealed finishes, gentle soap and water can be used.

Can damaged areas be repaired?

Yes. Minor scuffs or chips can often be spot-repaired without redoing the entire wall. We offer touch-up services for all our installations.
