Is Cement Plastering Required For The Room Ceiling?

The ceiling – often the fifth wall – is often overlooked when it comes to design and finishing touches. But, is cement plastering necessary for the room ceiling? When it comes to plastering, many are unsure whether it’s necessary for the ceiling, especially with modern alternatives available. Let’s delve into the world of plastering and explore whether it’s still the top choice for your room’s ceiling.

What is cement plastering?

Cement plaster is a mixture of cement, sand, and water that is applied to ceilings and walls to create a smooth and even surface.

What are the advantages and disadvantages of plastering a ceiling?


  1. Smooth and even finish: This is crucial for achieving a flawless finish for paint, wallpaper, or other decorative treatments.
  2. Durability: Cement plaster is a robust and long-lasting material that can withstand wear and tear.
  3. Protection: It protects the underlying ceiling from moisture, fire, and other environmental elements.
  4. Improved insulation: Cement plaster can help to reduce noise transmission and improve thermal insulation in your home.
  5. Decorative possibilities: While often used for a clean and streamlined look, some plasters can be textured to add visual interest and dimension to your space.


  1. Time-consuming: The application process can be time-consuming, requiring skilled labour and drying time.
  2. Messy: Plastering can be a messy process, requiring careful preparation and cleanup.
  3. Weight: Cement plaster adds weight to your ceiling, which might be a concern for older buildings or weaker structures.
  4. Skill requirement: Applying cement plaster requires expertise and experience. Hiring unqualified individuals can lead to poor results and potential damage.

Is it necessary to apply cement plaster on the ceiling of the room?

The short answer is: Not always. Whether or not you need to plaster your ceiling depends on several factors:

  • The desired finish

If you want a smooth and flawless surface for paint or wallpaper, then plastering is the way to go. However, if you’re planning on installing a false ceiling or using textured panels, plastering might not be necessary.

  • Condition of the ceiling

If the existing ceiling is already smooth and in good condition, you might be able to skip the plastering step. However, if there are cracks, unevenness, or other imperfections, plastering can help to create a clean and uniform surface.

  • Budget

Consider your budget and weigh the costs and benefits before making a decision.

  • Level of sound insulation

If you need to improve the sound insulation in a room, such as a home theatre or music room, plastering can be a good option.

  • Climate

If you live in a humid climate, consider the moisture resistance of different types of plaster. Some plasters may be more prone to cracking or peeling in humid conditions.

What are the alternatives to plastering a ceiling?

While cement plastering offers several benefits, it might not be the best solution for every project. Here are some alternative options to consider:

  • Painting

Painting directly onto the ceiling is a simple and affordable option. However, it will not provide the same level of smoothness or protection as plaster. This method is best suited for ceilings in good condition with minimal imperfections.

  • Drywall

Drywall is a prefabricated material that can be installed onto a ceiling and then painted. It is a relatively easy and inexpensive option compared to plastering. However, drywall is susceptible to moisture damage and may not be as durable as plaster.

  • Decorative panels

Decorative panels offer a unique and stylish way to finish your ceiling. They come in various materials like wood, metal, or fabric and can be easily installed. However, decorative panels can be more expensive than other options and may require additional maintenance.

  • Plasterboard

Plasterboard is similar to drywall but has a layer of plaster already applied to the surface. This option offers a smoother finish than drywall and some level of moisture resistance. However, it can be more expensive than drywall and may require additional finishing touches.

How do you choose the right plastering for your ceiling?

The best way to determine the best option for your ceiling is to consider your specific needs and budget. Here are some factors to help you decide:

  1. Desired finish: Do you want a smooth and flawless finish or a more textured look?
  2. Budget: How much are you willing to spend on finishing your ceiling?
  3. Skill level: Are you comfortable with DIY projects, or do you need to hire a professional?
  4. Condition of the ceiling: Is the existing ceiling in good condition, or does it need significant repairs?
  5. Moisture concerns: Is your ceiling exposed to moisture, such as in a bathroom or kitchen?

Pro Tip: Consult with qualified professionals to assess your specific needs and recommend the best type of plaster and cement for your project.

By considering these factors, you can make an informed decision about the best way to finish your ceiling and achieve the desired results.

How do you find a qualified plasterer?

Choosing the right plasterer is crucial for a successful project. Here are some tips:

  1. Ask for recommendations: Ask friends, family, or neighbours for referrals to reliable plasterers.
  2. Search online: Do an online search for local plasterers and read customer reviews.
  3. Get quotes: Compare quotes from several different plasterers before making a decision.
  4. Check credentials: Ensure the plasterer has the necessary qualifications and experience.


Whether or not to use cement plaster on your ceiling depends on your specific needs and preferences. Consider the pros and cons of different options, weigh them against your budget and desired look, and consult with a professional if necessary. Remember, the right ceiling finish can enhance the aesthetics and functionality of your space, making it a worthwhile investment in your home.
