Question 1

What is the difference between microcement and Venetian plaster?

Accepted Answer

Venetian plaster is a lime-based decorative wall coating applied by hand to create a polished marble-like finish. Microcement is a polymer-modified cement that can be applied to floors and walls and, critically, made fully waterproof. Venetian plaster is decorative and not waterproof.

Question 2

Is Venetian plaster waterproof?

Accepted Answer

Standard Venetian plaster is not waterproof. It can be treated with wax for some moisture resistance but is not suitable for shower enclosures, wet rooms or kitchen splashbacks. Microcement, when sealed, is fully waterproof.

Question 3

Which is more expensive, microcement or Venetian plaster?

Accepted Answer

Venetian plaster is a highly labour-intensive hand-applied finish and can cost more than microcement per m2 for high-quality work. Microcement typically costs 70 to 120 euros per m2 for walls installed. Venetian plaster from a skilled craftsperson can cost 80 to 200 euros per m2.

Question 4

Can Venetian plaster be used in a bathroom?

Accepted Answer

Venetian plaster is generally not recommended for bathrooms, particularly shower enclosures or wet rooms, due to its lack of waterproofing. In dry bathroom areas it can work but requires careful maintenance. Microcement is the better choice for any wet bathroom application.

Question 5

Which is more durable — microcement or Venetian plaster?

Accepted Answer

Microcement is more durable in most residential contexts. It is harder, more resistant to knocks and scuffs and can be resealed easily. Venetian plaster scratches and marks more easily and can be difficult to repair invisibly.

Question 6

Can I have Venetian plaster and microcement in the same home?

Accepted Answer

Yes. Many Irish interiors combine Venetian plaster on feature walls in dry living areas with microcement in wet rooms, bathrooms and on floors. The two materials have complementary aesthetics and complement each other well.
