Can decorative plaster be used in the bathroom

A restroom with a unique atmosphere is called a bathroom. Finishing materials must, of course, be safe for human health, resistant to moisture and temperature changes.

Decorative dry mix meets every need to a tee: it absorbs excess moisture and forms a breathable, vapor-permeable coating without producing a greenhouse effect.

Fungicidal agents are added to the material by manufacturers in order to stop the growth of mold and mildew. You can create coatings that mimic different natural materials, whether they are textured or smooth, thanks to modern technologies. Furthermore, a decorative plaster bathroom is no longer unique.

It is advised to use mixtures in a wet room. Different binders are used to make these mixtures:

• acrylic resins – a universal coating is characterized by a short drying time at any temperature and humidity in the room, durability, resistance to mechanical impacts. Manufacturers guarantee its service life of at least 15 years. You will find ready-to-use compositions on sale;
• minerals – absolutely safe for health decorative plaster is made on the basis of lime, cement, minerals and small inclusions. It is characterized by low cost, ease of application, good strength characteristics for finishing walls in the bathroom. The only conditional disadvantage when working with it is the need for careful preparation of the walls with grouting of all irregularities and cracks;
• silicone resins – thanks to them, the material is characterized by plasticity, good air permeability and durability. Of all dry mixes, this is the most expensive type. Therefore, decoration of the bathroom with decorative plaster using silicone resins – the repair is not cheap, this should be taken into account when laying the budget.

Moisture-resistant decorative plasters manufacturers and features

The price/quality ratio is the deciding factor when selecting decorative plaster that is resistant to moisture. We discuss the Volma brand gypsum mixture with polymer filler in this section. It adheres firmly to the surface it is applied to and sets quickly. The mixture is resistant to mechanical damage and moisture.

Rotband dry mix will cost more, but it will also be of better quality. Its composition, which can mimic various textures, has a plastic structure and can be applied in layers up to 5 cm thick.

Composition of dry buildings Excellent mechanical strength, durability, and vapor permeability characterize "Silcoat." It can be used for outside projects as well as interior wall decoration. It is more frequently used, though, to make thin coatings that mimic silk.

Features of use

A few basic requirements must be met for the coating to last a long time:

1. application of a primer on a prepared base surface;
2. application of a sanitizing mixture to create waterproofing;
3. use of a finishing coat to protect the decorative layer from the negative effects of moisture.

Cement compositions should be used for foam blocks, and gypsum-based mixtures for aerated concrete cladding walls.

Using specific tools to apply a smooth or structural layer is one of the benefits of using moisture-resistant plaster in the bathroom. It is also important to take into account the materials used to complete the work.

Additionally, follow the manufacturer’s recommendations for applying decorative coatings, as stated on the label. These include considerations for the amount of dilution needed for dry mixtures, the type of primer to use, and the weather during the project.

Pros and cons

Decorative plaster finishing in the bathroom has the following benefits:

• ease and convenience of application;
• safety of the coating for health;
• long service life;
• strength and decorativeness;
• lack of joints, which is especially important in the design of a small bathroom.

It should be mentioned that decorative plaster can be used without sacrificing aesthetics in both large and small spaces.

It is challenging to identify this material’s drawbacks, but there is one—cost. Everyone has the freedom to choose, even in this case, as some decorative plaster varieties are more costly than others. Select the option that works best for painting your bathroom’s walls.

Which type of decorative plaster to choose for bathrooms

The primary factor to consider when selecting a decorative coating for a bathroom is its ability to withstand moisture.

Based on the owners’ individual preferences, all other factors—ready or dry mixture, with or without additives, "under the color" or colored—are taken into consideration. Of course, you could fix the problem yourself by pouring decorative plaster yourself in the bathroom. However, purchasing a ready-made composition is simpler.

Let’s discuss the various kinds of ornamental plaster.

Textured

Components of various sizes are added during the creation of textured coating. Mixtures with medium, large, and fine grains are the end product. They work in tandem with a variety of tools to create an imitation of natural surfaces on the wall, such as stone, concrete, fabric, and skin.

Venetian

Using Venetian marble to decorate the interior of a large bathroom is a great choice.

This is a thin layer of multiple layers that mimics the marble slab’s cut. Natural ingredients include marble dust, coloring agents, and gash. If you’ve decided to use Venetian plaster, you should be aware that while it will require some expertise to work with, the outcome is worthwhile.

Structural

One distinguishing feature of multi-component decorative plaster is the addition of inclusions to the original mixture of different diameters. These could be sand, fibers, or pebbles. You can get different patterns with the tool depending on how much pressure you apply.

It is preferable to use compositions with polymer compositions in the bathroom because they are moisture-resistant and inhibit the growth of mold and mildew.

The size, shape, and application thickness of the chips in plasters vary; these factors are critical to achieving the desired outcome.

Moroccan

This coating is also known as tadelakt. Moroccan plaster is made up of a complex composition that is environmentally friendly, highly water-repellent, and colored with two pigments.

The only drawbacks to this decorative plaster are the cost and the difficulty of applying the mixture.

Tools for work

Get everything ready before beginning the cladding:

• trowel;
• spreaders of different sizes;
• container and mixer for mixing the dry mixture;
• protective equipment: gloves, glasses;
• tools for applying plaster;
• primer, putty, sanitizing plaster;
• stepladder.

For bathroom walls, moisture-resistant decorative plaster is a chic and useful choice that provides a long-lasting finish that withstands moisture while bringing texture and personality to the area. Water-repellent qualities combined with a wide range of design options—from sleek, contemporary finishes to textured effects that resemble stone or concrete—are features of this kind of plaster. It’s the perfect option for both traditional and modern bathroom designs because of its long-lasting appeal and minimal maintenance requirements.

How to properly apply decorative plaster

A spatula, roller, sponge, or brush is used to apply the finishing material to the surface that has been cleaned and prepped.

Before working with decorative plaster, we advise you to practice applying the material on a small surface using various techniques.

Preparation

Among the preparatory tasks are:

• removing old material;
• widening cracks and filling voids with putty;
• priming the walls in two layers for better adhesion of the material to the base;
• covering the surface with two layers of sanitizing plaster to waterproof the room and prevent salt deposition. The surface is leveled with a float during work, until the layer of material has dried.

Application

As directed, the dry mixture is made, and if needed, it is tinted. Apply the decorative plaster in the selected pattern after the sanitizing layer has dried.

• A portion of the mixture is applied to the trowel using a spatula.
• The solution is applied to the wall with short arcuate movements or "overlapping". You can use the "unsticking" method of the trowel. To do this, the tool with the mixture is applied to the surface and torn off with the entire plane.
• Unusual and original reliefs are obtained with the help of rollers. For this, the following attachments are used: fur, structural, smooth. An option for creating a unique pattern would be to wind various materials onto the roller: bags, paper, twine.
• With blotting movements, a sponge can be used to treat the entire surface or areas.
• You can decorate the walls with "furrows" using a hard brush. To do this, a slightly dried layer of plaster is treated with a tool with stiff bristles in a horizontal, vertical direction or in a wave-like manner.

How to cover decorative plaster in the bathroom

Use paints or varnishes with silicone or acrylic bases as a protective coating for bathrooms. Once the primary composition has dried, they are applied in one or two layers.

The coating prolongs the plaster’s service life by creating a film that is resistant to moisture.

Care of the coating

You will need water, non-aggressive detergent, and rags to clean the ornamental material. It is sufficient to clean the bathroom once a week with their assistance to keep it clean. Vacuum cleaning by dry means is acceptable if the surface is embossed. EDp-JdeS2aU can be seen on YouTube.

For bathroom finishes, moisture-resistant decorative plaster provides an elegant and long-lasting option. It combines a broad range of design options with functionality to suit a variety of aesthetic tastes and withstand the humid environment.

This type of plaster allows you to add unique touches to your bathroom with options like creative patterns, smooth textures, and imitations of natural materials. Unending creativity is possible due to the range of colors and finishes that are offered, all without sacrificing longevity or protection.

Decorative plaster that resists moisture is an investment in a finish that looks good and lasts a long time. It’s the perfect option for people who want to add style to their bathroom without sacrificing functionality or upkeep.
