Your guide to everything plastering

What is plaster, why is it needed, and what types are there? These are great questions for any person considering plaster repairs, renovations or those building a new dwelling.

Depending on the job requirement there are a plethora of options for people to consider when it comes to the linings in their home, office or renovation project. So let’s start at the beginning of why, where and when plaster products may or may not be required to suit your particular project:

After the construction of walls, partitions, and roofs, it’s time to start the finishing work. A classic option for internal wall and ceiling lining is to plaster them. Despite the emergence of many new materials, plastering the ceiling and walls remains the most popular way of decorating.

Its indisputable advantage is considered the minimum thickness and durability of the coating, which is often an essential criterion in the requirements for the finishing method. A building with high-quality stucco and colouring always look fresh and modern, and its diverse textures allow you to recreate any style in the room. Below is a complete guide on all you need to know concerning plastering:

How To Choose The Best Type of Plastering?

Today, finishing materials for walls are presented in a wide range, which creates difficulties in choosing the right material. Moreover, the difficulty is not even what manufacturer to prefer, but what material to choose for wall decoration in your home. Wallpaper with a variety of textures and colours, paint, plaster, murals, drywall, gypsum sheets, various types of tiles, lining, and other shaped wood products, plastic panels, acoustic plasterboard, insulated plasterboard, fire rated or feature walls using venetian plastering or decorative stucco mouldings and much more. It’s easy to get confused about this variety of materials.

Each of the types of finishing materials for walls has several features, advantages, and disadvantages. If you know the main characteristics of the product, it is much easier to choose materials for finishing a particular room. In this article, we will tell you about the types and purposes of such finishing materials.

How To Choose Your Plaster

It is logical to assume that with all the variety of methods and materials for plastering, the consumer has a question – which plaster is better? There can be no single answer. This is explained by the fact that the choice of the “correct” plaster can be determined only by knowing the specific operating conditions and the method of work. The cost factor plays not the last role in the choice. The latest fashion trends brought with them the latest materials, at times, superior in value to their counterparts that are quite full in every sense.

When creating interior design, the question of the harmonious combination of styles and materials remains relevant. You must admit that not always a “cool Venetian” will be appropriate in a residential apartment. Conversely, spacious halls and living rooms can look much more attractive with suitable wall decoration. The answer to the question of which plaster to choose depends on the interior of the room and the effect you want to achieve.

What Are The Classifications Of Plasters?

Drywall Plaster

Plasterboard sheets manufactured at the factory are used exclusively for wall cladding indoors. The dimensions and operational characteristics of the material make it possible to carry out work in a short time with a final result of high quality. For installation, a galvanized profile is used, which is mounted on the walls in a level using special brackets.

When placing a profile, the size of the sheets is taken into account. The fastening of drywall to the profile is performed with screws. The joints and fasteners are levelled with putty followed by stripping. For the final alignment, abrasive meshes of different grain sizes are used.

Advantages of Using Drywall:

Speed of work.

The efficiency with which the result is achieved is associated with ease of installation and the absence of “wet” processes.

Drywall Installation Does Not Require a lot of Skills.

The relative ease of installation and the quality of modern materials can do without the cost of highly paid specialists.

Provide internal Partitions Without Walls.

The design of profiles and fixtures of drywall sheets provide for the installation of internal partitions without walls.


  • Exposure to atmospheric conditions.
  • In some cases, insufficient strength.


Work on the application of plaster mortar on the walls to level or give a certain colour or texture is called monolithic plaster. The result of such action is a layer resistant to mechanical and weathering.

Main advantages:

  • universality
  • durability
  • minimum occupied space


  • design weighting
  • extended terms due to the need to dry each layer
  • cost

Types of Decorative Plaster For Walls and Its Features

The most striking representative of this class of material, which is known to almost every person, is Venetian plaster – it imitates a marble surface. In addition to it, there are many other varieties of such materials – there are both widely known and few people familiar with it. The beauty of this type of plaster is that it is unique – especially when it comes to the creative approach of the master to its manufacture. In principle, in some way, an application of such plasters can be called art – a real master with the help of special mixtures can draw any picture on the wall. This is the whole essence of decorative plaster for interior work. And one more thing – a clear line should be drawn here. Most people do not understand the difference between decorative plaster and textured plaster. If the first can be attributed to art, then the types of textured plaster are not such – it is rather a mechanical work, with the help of which an abstract surface with ordered irregularities is created.

Decorative plasters for outdoor use.

If we talk about the bright representatives of this group of materials, then, of course, plaster can be called “bark beetle” and “pebble.” Their finished composition contains small granules of a rounded shape, due to which a structured surface is obtained – there are few of these granules in the bark beetle, but the pebble is simply abundant in them. Such plaster can be made both on a mineral basis in the form of dry building mixtures and in the form of a ready-to-use composition on an acrylic or silicone basis. The latter are considered professional, and working with them is much more difficult.

Special Plasters: Types and Purpose

When studying varieties of modern plasters, special plasters cannot be ignored – in most cases, these are rough types that help surfaces acquire additional qualities.

  1. Acid-resistant plaster.

In everyday life, it is practically not used (we can say that it is not used at all). Its purpose is enterprises, especially those involved in the production of chemicals. Such a plaster can withstand very long exposure to strong acids. These are cement-sand plasters with the addition of water glass, quartzite, and stone flour – these fillers give the usual solution to the desired properties.

  1. X-ray protective plaster.

The main component of such mixtures is barite concentrate, which is an excellent alternative to individual lead plates, the cost of which is very high. As a rule, it is applied to the surface with a layer of 50 mm. If a thicker layer of protection against x-ray radiation is needed, then plates are made from barite concentrate solution, that is reinforced with metal from the inside.

          3.Warm plaster.

It appeared relatively recently and has already managed to win the recognition of many residents of the private sector. In fact, this is the same cement-sand mortar into which warming filters are introduced. The cheapest of them is paper, and the more expensive analogue of such a filler is cellulose, polystyrene foam in granules, cork chips, and similar materials can also be used. A small and large amount of such a mixture can be prepared at home – all that is needed for this is to add a warming filler to the sand and cement. The effectiveness of warm plaster is slightly lower when warming the walls with foam.

Plaster Leveling Mixtures

It is no secret to anyone that all modern types of plaster can be divided into levelling and decorative. The former is used for rough finishing of walls, and the latter is used as a topcoat. Let’s start in order – with the drafts. These include the following varieties of this finishing material.

  1. Cement and sand plaster.

This is the strongest and most time-consuming material to align on the walls. Another negative point of this type of plaster is the need to fine-tune the surface obtained with its help. As they say, to the ideal – in almost all cases, cement-sand plaster is additionally covered with putties. Unless additional processing, tiles, and most types of panels can be installed on clean plaster of this type. Cement-sand plaster can be used for both indoor and outdoor use.

          2. Lime plaster.

In principle, this is practically the same as the previous one, and only lime is used in it instead of cement, which makes the solution more plastic, light, but at the same time soft. This type of plaster mortar also requires final finishing with putties. For the decoration of external walls, this type of plaster is not used.

  1. Gypsum plaster

It is used exclusively for interior use. Its main advantage lies in the absence of the need for subsequent refinement to the condition – as a rule, the surface obtained with its help can be immediately glued with wallpaper and, in general, with any other finishing materials. Gypsum plaster can be applied on the surface both manually, using standard tools, and by machine. The latter is more attractive – it is applied faster, and the surface is better.

Pricewise: How much does it cost to supply and install plasterboard?

The average cost of one 2400 x 1200 x 10mm sheet of drywall today is about $15. However, in addition to the sheet itself, additional costs will include supplying accessories like jointing tape, trim beads, steel profile beads, screws, dowels, sometimes battens, stud glue and ultimately add a considerable amount of money of approximately $15 to $25 per square metre total cost including installation.

Purchasing materials for plastering also includes the cost of the building mixture itself, ultra top coating, and sanding papers. But there is a way to save, if you do not buy premixed jointing compound and instead use jointing plaster powder in bags and mix it yourself.

What is better to use to preserve the indoor space in the room

Depending on the quality of the surface, the thickness of the plaster layer, as a rule, does not exceed a few centimetres. Even if all the walls in the room are finished with plaster, the loss in the area will be minimal.

With drywall, everything is somewhat more complicated. Drywall standard sheet thickness for walls can be 10 – 12.5mm and even up to 90mm for insulated plasterboard. If we add all the thickness of the materials like stud glue, jointing, it turns out that the entire structure using gypsum plasterboard will only reduce room sizes by an noticeable amount.

The role of ornament on gypsum mouldings

Gypsum cornices with various patterns and curls are divided into geometric, floral, and animalistic themes. They always look luxurious and aesthetically pleasing. The presence of volumetric details and clear textures is the main advantage of this type of gypsum cornice, as it allows you to hide irregularities and various flaws in the walls visually.

Plaster cornices with ornaments are also often used for zoning the room. And the effect of layering gives the room a feeling of airiness and certain greatness. But there is one limitation – this is the styling. Such curtain rods are not quite relevant for office premises, as well as modern styles. Remember that a cornice with something like a ceiling rose, unlike the smooth version, simply cannot go unnoticed and always focuses on itself.
