When it comes to high-end, visually striking interior surfaces, two finishes dominate the conversation: polished plaster and microcement. Both offer seamless, modern aesthetics — but they differ significantly in terms of composition, application, and performance.

Whether you're an architect, interior designer, or developer looking to specify durable and elegant wall or floor finishes, this comparison will help you choose the best solution for your next UK-based project.

What is Polished Plaster?

Polished plaster — often referred to as Venetian plaster — is a decorative wall finish made from lime, marble dust, and natural pigments. Applied in thin layers with a trowel and then burnished, it creates a smooth, reflective surface that mimics stone, marble, or even metal depending on the formulation.

Key Features:

• Breathable and natural

• High-end, timeless aesthetic

• Excellent for heritage or classical design schemes

• Available in matte to high-gloss finishes

What is Microcement?

Microcement is a polymer-modified cement-based coating applied thinly over floors, walls, and even furniture. It delivers an ultra-modern, industrial feel with a smooth or lightly textured look.

Key Features:

• Seamless and waterproof (when sealed)

• Highly durable — ideal for wet areas

• Can be applied over tiles, concrete, plasterboard, etc.

• Available in various colours and finishes (e.g., satin, matte)

Side-by-Side Comparison Table

When to Specify Polished Plaster

Choose polished plaster when the project demands:

• A bespoke, hand-applied texture with natural movement

• Luxury or heritage interior detailing

• Breathable walls (e.g., listed buildings, lime substrates)

• Soft tactility and depth in surface finish

Example Application: Boutique hotels, listed properties, feature walls in reception areas

When to Specify Microcement

Choose microcement when the brief calls for:

• A sleek, seamless look across floors and walls

• Durability in wet zones (bathrooms, kitchens, spa areas)

• A modern, minimalist finish

• Overlaying existing surfaces (tiles, screed, etc.)

Example Application: Contemporary bathrooms, retail fit-outs, loft conversions, restaurant floors

FAQ: Polished Plaster vs Microcement

Is microcement waterproof?
Yes — when sealed correctly, microcement is completely waterproof, making it ideal for bathrooms, kitchens, and even wet rooms.

Can I use polished plaster in a shower area?
Polished plaster is not naturally waterproof, but with the right sealants, it can be used in splash zones. However, for full wet areas, microcement is typically the better choice.

What’s more durable — microcement or polished plaster?
Microcement is generally more durable and impact-resistant, especially for floors and high-traffic areas. Polished plaster is best suited to decorative wall finishes.

Can both finishes be applied over existing surfaces?
Microcement can be applied directly over tiles, screeds, or plasterboard with minimal prep. Polished plaster usually requires a more specific substrate for optimal adhesion.

Which is more cost-effective?
It depends on surface size, substrate condition, and design complexity. Microcement may offer better long-term durability in functional spaces, while polished plaster delivers premium visual impact.
