Decorative plaster for the bathroom is on sale in hardware stores and it is not difficult to purchase it. But you still need to make the right choice, because it has several types. And after that, apply according to the technology, the quality of the coating and its service life will depend on this.
Decorative plaster for bathrooms today will be considered by us and after that you can not only choose it, but also apply it correctly with your own hands. Then the price of the coating will be much lower.
Rules for the use of decorative plaster
Decorative plaster in the toilet and bathroom can be applied to almost any substrate. It is just that the surface must be carefully and thoroughly prepared. And this is done with the help of sanitizing plaster. She not only aligns them. Thanks to her, the walls acquire the ability to absorb moisture. This is a variant of a cement mortar with the addition of elements that provide the specified properties for the surface of decorative plaster in the bathroom.
It:
- Water resistance... After drying, a thin layer of protective film forms on the surface, which prevents moisture penetration.
- The resistance of this composition to salt deposits... Prevents the formation of salt deposits that have a destructive effect on materials. This is typical for cement based mortars.
- High hygroscopicity contributes to the creation of a comfortable microclimate in the bathroom.
I must say that sanitizing plaster is relatively easy to apply to the surface. This work can be done independently, without resorting to professional plasterers. It must be remembered that we are now considering a working mixture that only evens out the surface and endows it with the necessary characteristics, and does not solve the problem of decoration.
Finishing methods
The technological process of manual plastering of bathroom walls actually does not differ from ordinary surface finishing inside the room. Differences appear only at the final stage, when the final layer of decorative plaster is applied to the leveling layer with waterproofing.
And to apply it, use the following methods:
|
Homogeneous variant |
By means of crumpled paper placed in a plastic bag, a foam sponge or an ordinary broom, a relief is made that looks like a skin with small pimples. This should be done over wet plaster. |
|
Furrowed version of plaster |
With a simple spatula, we carry out punching on a fresh layer, thereby imitating a masonry of stone or brick. |
|
Rough plaster option |
When large fractions of elements are added to the working solution and, when applied to the wall, is smoothed with a simple float in the vertical and horizontal directions, while forming characteristic grooves. |
|
|
It is carried out by sequentially overlaying layers of special mixtures with different color shades. This is followed by repeated grouting and scraping. This imitates natural masonry. This is the most complex of the methods discussed. |
|
Lumbering version of plaster |
Fascinating and unusual antiquity effect and blurred background. |
|
Flock coating |
It gives the impression of a mosaic tile. |
|
Multicolor for finishing |
Creates a balsa wood surface. |
An inimitable interior can be created using ready-made stencils that are offered by hardware stores.
Choosing the type of decorative plaster
Carrying out all the preparatory work makes it possible to choose any type of decorative plaster. There are no limiting factors, but it is advisable to know the differences between the available samples.
Venetian
Refers to smooth types of decorative plaster and is used indefinitely for bathroom decoration.
It:
- The glossy finish is water repellent. It rolls down without harming the coating itself. Imitates natural stone, most often marble.
- The quality of the pattern will depend on the size of the particles of marble or quartz dust. The smaller they are, the softer and more beautiful the drawing will be.
- An integral component of the solution will be slaked lime, which serves to bind it. Don't count on special diversity.
- For the most part, you will have to choose only from the color palette and one or another effect (an example of a cracked surface).
- Previously, the solution was stained using clay. today acrylic additives are used to obtain the desired color.
- Using handmade stencils and drawings made by yourself, you can diversify the assortment. But this will inevitably increase the price of work, although this can be attributed to any type of finish.
Structural plaster
It includes multiple textured plasters: "fleece", "fireclay", "bark beetle", "frost". They include mineral elements and quartz sand.
- A pattern is made with a spatula or trowel, depending on the size of the inclusions and the direction of movement of the tool. Such work requires special skills. Until the surface grasps, the drawing can be edited and corrected.
Note: Experiment and don't forget that when dry the surface will become more expressive than when applied. The plane takes on a "pebble" effect.
- It looks very nice, it seems that the wall is made of solid seamless stone. It is very important to follow the principles of applying such a finish. The main disadvantage is irregularities in which water droplets are retained. The service life of such plasters is shorter than that of smooth plasters. Although in the short term, such a structure does not have much effect on the condition of surfaces.
What should you pay attention to, first of all, when choosing these types of plaster for finishing your bathroom?
- The market offers both dry building mixtures and ready-made compounds. Keep in mind that working with ready-made ones is complicated by the fact that they must not be diluted with water, and therefore it will be difficult to get the desired consistency.
- Solutions with coarse-grained fillers are applied strictly by hand. It is very difficult to work with formulations that include various fillers. If you nevertheless decide to do it yourself, it is better to refuse to use such mixtures.
- It is preferable to use non-water based plasters. On the one hand, they do not emit harmful substances and are safe, and on the other hand, they have poor water permeability. This drawback can be corrected by applying a special composition of wax to the surface, after the leveling layer has completely dried.
Mixtures that do not contain water are not always safe, although their service life is disproportionately longer. In order for the repair to meet expectations, before purchasing plaster, be sure to evaluate all the advantages and disadvantages of this type.
Features of applying plaster
The instructions for applying decorative plaster in bathrooms do not differ significantly from those in other rooms.
- Priming the walls in the bathroom with great diligence and more than once. After all, its task is not only to strengthen and fasten surfaces, but also to protect them from water penetration. Apply the first layer liberally and wait until it is completely dry, the second one is applied just before applying the plaster and serves to completely remove dust. The choice of the type of primer is very important. Most often it is a soil with quartz sand, which increases the adhesion of the decorated surfaces many times over.
- The primer application process also varies. The mortar applied to the surface is properly compacted using the grouting method. This must be done while the mortar is drying with a steel spatula or trowel. Otherwise, this process is called iron.
- After that, the plaster itself is applied.
- Now you will need to apply the desired relief. For this, various stamps are used or masters. This is done with a simple spatula.
- Controlling surface drying is another distinctive feature. The initial drying time for decorative plaster in the bathroom is 3-5 hours. But during this time the walls have not yet acquired the desired characteristics.
- A relatively normal use of the bathroom is possible only after 72 hours. If you can do without a bathroom, then it is better to extend this period to a week. By this time, the polymerization of the plaster ends and the walls acquire the necessary characteristics.
Attention: The statement that decorative plaster is unsuitable for decorating bathrooms is erroneous. If the technological process is followed and everything is done properly, then its operational life is comparable to the service life of tiles.
