How to make your home sophisticated with plaster mouldings
Robert Rivera

The plaster moldings are used as an alternative to the ceiling, bringing a modern and different look to the house. As the Rio de Janeiro architect Monica Vieira explains, the molding consists of a plaster finish used between the ceiling and the walls.

Amanda Ciconato and Glauco Mantovanelli, architects from Studio A+ G, explain that the molding makes the room more sophisticated and helps by working with different colors and illuminations. Therefore, this type of finishing is recommended to highlight the space, and can be used in any environment.

This method is gaining many followers due to its practicality, beauty, and considerably low investment. Its versatility allows the sconce to be used in different decoration styles, from modern to more traditional.

Plaster mouldings in inspiring environments

When choosing to use a plaster molding, it is important to know the dimensions and level of the piece to be applied. The architects Paula Werneck and Renata Kinder, from the office PW+RKT Arquitetura, inform that the plaster moldings are sold in standard size, and it is necessary to model them to be "installed by a metallic rod that is fixed directly to the slab by gun-shot.

Amanda and Glauco warn that "it is essential to check the horizontal alignment of the line that will guide the installation, as well as the correct distance between the fixing points of the tie-rods, which cannot exceed 1 meter.

Plaster molding x Plaster lining

In addition to the molding, the plaster ceiling tile is also widely used in architectural projects. The architects at Studio A+G say that, although both styles "form" the ceiling, the plaster is usually lowered while the molding is applied between the ceiling and the wall.


Paula and Renata say that the moldings can be used in smaller environments, allowing the composition with the existing slab. Monica adds that this resource was highly used until the 19th century, before it was abolished by modern architecture: "Nowadays, we use plasterwork much more for technical reasons, to embed pipes, for example", adds the Rio de Janeiro professional.

The creation of slots in the plaster allows the use of indirect lighting in the room, and it is also common not to lean the molding against the wall, creating a shadow area and delimiting the division between the walls and the ceiling.

Advantages: The piece works as a beautiful detail in the decoration, besides not being very expensive. Its versatility offers the possibility of exploring colors and formats in a freer way.

Disadvantages: Depending on the room, its use can make the installation of recessed luminaires more difficult, and its application is more laborious and time consuming.


Monica explains that the ceiling tile is a recess in the ceiling, covering it totally or partially. The ceiling tile plaster can also be treated to serve as acoustic insulation, ensuring calmer and more relaxing environments.

Amanda and Glauco state that a commonly used model is the straight ceiling tiles with tabbed finishing. In addition, if the room has few light points on the slab, the lower ceiling tile helps to better distribute the room's lighting.

Advantages: the ceiling tile can hide pipes and allows the installation of lighting fixtures in several points, ensuring greater flexibility in the lighting design. Its installation is fast.

Disadvantages: In addition to lowering the room's ceiling height, the lining is more expensive than the molding. Its finishing is simpler and less flexible.

Whatever type of coating you choose, it is important to seek a professional so that it can be planned and adapted to the room in the best possible way.

Learn about the different types of plaster mouldings

There are several types of plaster sconces, each with its own peculiarities and advantages. The choice of model will depend on how you want your environment to be, in addition to the needs, limitations, and opportunities that the structure offers.

  • Open ceiling: Paula and Renata explain to us that, in this type of molding, the light fixtures can be recessed to provide indirect lighting.
  • Closed ceiling: Because it does not offer any type of opening, Renata and Glauco warn that, with the closed molding, it is only possible to use direct lighting, with spots or even recessed lighting fixtures: "This model of molding has a simpler final effect, but it is possible to make several formats", they point out.
  • Inverted molding: The architects from studio PW+RKT say that the inverted panel follows the same proposal as the open one, but with the opening facing the walls. In this case, indirect lighting can also be applied, with the light facing the walls.

Depending on the environment, it can be interesting to use colors and textures in the molding, but always being careful with excess information. In the case of small environments, it is important to remember the maxim "less is more".

How to choose the best lighting for your vault

The dome lighting can drastically change the environment, defining the style of the room and bringing comfort. Monica explains that it is possible to use LED strips with a weaker light, as well as tubular fluorescent bulbs. Another option are recessed spots, which "are widely used for being discreet and for providing a directed light, for a painting, for example.

Paula and Renata warn that it is necessary to check the height of the ceiling height, because the more restrictive it is, the smaller the lamp should be. Its intensity varies according to need, and it can be more decorative than necessary for the environment illumination.

Glauco and Amanda suggest the use of LED strips in inverted moldings, which can be white, colored, or red, green, and blue (RGB), which changes color depending on the configuration. The lighting can highlight the colors or textures of the molding and walls.

4 considerations to make before choosing the plaster moulding

Before deciding to use the plaster molding, it is important to check if the option is the best for your space. It is worth remembering that the project must be carried out with the help of a professional, to avoid mistakes and wasting money.

  1. Choose a point of emphasis: Amanda and Glauco suggest that, instead of covering the entire room, it may be more valid to use the molding to highlight some part of the room, such as a dining table or a painting.
  2. Check the height of the room: In case the space is low and you still want to use a molding, opt for one in neutral colors.
  3. Have a goal: The indirect lighting creates a more sophisticated environment, while white LED strips can give a more modern look. The molding or colored lighting makes the environment more daring, so the option must match what you want to convey.
  4. Keep an eye on the budget: as much as the use of a molding may not weigh as much when building or remodeling the house, investing in a good architect or designer can save money and time, besides having a guaranteed quality end result.

The most important thing is to always have a professional to accompany the project and to be careful not to commit excesses, so that the space does not become polluted.
