Moisture -resistant putty for the bathroom: Features of use

The putty, with which the walls in the bathroom should be finished with certain properties that ensure the quality of its application. Regardless of the further decoration of the walls in the room, the putty for walls in the bathroom should be:

• Sustainable to moisture - ordinary putty, under the influence of moisture, swells, exfoliates, deforms and generally destroys, moisture -resistant materials, under the influence of moisture, should become stronger;
• Long -term in operation - the minimum life of the putty, after applying it to the walls, should be twenty years;
• persistent to changes in the temperature regime - since the bathroom is a room with an unstable temperature regime, putty for walls should easily transfer these vibrations, expansion and compression of putty when temperature changes leads to its destruction.

Please note that these criteria are decisive when choosing a putty composition for wall decoration in the bathroom. Individual additions depend on further wall decoration. So, for example, if, after decoration, the wall in the bathroom is painted with paint, then the surface should differ in perfect evenness, which means the putty should perfectly go to the wall. For walls, the decoration of which is performed with tiles, this criterion is less important.

For wall decoration in the bathroom, such options for compositions with a mineral or polymer base are used:

1. Sapakovka for a bathroom based on cement.

For the manufacture of this composition, high -quality Portland cement is used. He, when exposed to moisture on it, becomes even more durable and strong. The coating, after applying to the wall, is additionally wetted with water. The main components of this composition, in addition to cement, are small sand and clinker crumb. In order to improve the plasticity of the composition, various kinds of additives and fillers are added to it.

2. Acrylic or latex putty compositions based on polymers.

It consists of various kinds of mineral and synthetic additives. These composition is more plastic than cement. It does not give shrinkage, easily applied to the wall, distributed on its surface. However, the cost of such putty is an order of magnitude higher than that of the cement analogue.

Some experts use facade putty for wall decoration in the bathroom. However, before buying the composition, make sure that it does not contain harmful or toxic substances.

The mixtures on a gypsum basis are not recommended for wall decoration in the bathroom in any case, despite the fact that some of these compositions also have moisture resistance. This type of finish is not able to withstand a constant pair and a change in the temperature in the room.

In the response to the question, the putty for the bath to choose, we definitely recommend stopping on the acrylic or latex version of the composition. If the cost of the composition is crucial for you, then purchase putty on a cement basis with moisture -resistant characteristics.

Moisture -resistant putty for drywall: choice and characteristics

In the ratio with the appointment, putty for drywall is divided into types:

1. The putty moisture -resistant putty is more often sold in the finished form, used for the final decoration of the walls in the room. After the finish is performed using the finish, the walls are prepared for painting.

2. The putty is aligned moisture -resistant - used for primary leveling of the wall, this composition allows you to get rid of joints between canvases, holes for fasteners, etc.

3. Universal putty compositions - allow you to align and final finish at the same time.

In the ratio with the composition, the moisture -resistant putty of the bathroom happens:

1. Compounds, based on gypsum - do not give shrinkage, but differ in poor moisture resistance.

2. Cement compounds - have excellent moisture resistance, resist mechanical influences well, but give a small shrinkage. Using such compositions, wall decoration in the bathroom under the tile is performed.

3. Polymer putty mixtures are the best option for perfect wall alignment. The putty has high plasticity, is well distributed on the wall, aligning it. The only drawback is the high cost is quite justified by the operational characteristics of the material.

However, keep in mind that before applying any mixture in composition, it is necessary to cover the walls with a primer, which will provide high -quality grip of the wall with the material and perform an antiseptic function.

In terms of readiness for use, moisture -resistant putty for the bath happens:

• Dry - water will require water for breeding this material, the compositions are less convenient to use, as they require compliance with a certain consistency and use of a mixer for their manufacture, in addition, such mixtures are rapidly hardened, so they are prepared in small portions;
• Ready - the compositions are more expensive, but are convenient to apply, before applying the composition, it is quite well mixed, in addition, their storage period is quite long, over time they do not lose their characteristics.

Putty moisture -resistant price and tool for application

In the process of putting the walls, it is necessary to prepare in advance the equipment that will be needed when working. First of all, stock up on spatulas of different sizes by which the putty will be applied to the wall.

If you use a dry composition, then prepare materials for its breeding. A bucket or additional container, water, a drill with a mixer nozzle or a construction mixer.

Also, it is necessary to choose a primer in advance, the type of which is determined by the type of putty used in wall decoration. The putty is applied to the wall with a wide spatula, and it is applied to a wide spatula. In the presence of more than one square meter of wall area, use the rule to equalize it.

In order to avoid the appearance of cracks on the walls, a grid is used in the process of putty, which improves the mechanical strength of the composition.

Bathroom putty for painting: features of application

The putty for the bathroom for painting should have such operational properties:

• high moisture resistance;
• antiseptic characteristics that prevent the development of fungus and mold in the bathroom;
• minimum porosity;
• High adhesion with the base, regardless of moisture and temperature difference.

It is with the help of the polymer composition that it is possible to create the perfect coating for painting walls in the bathroom. Contacting with air, putty is polymerized, differing in high performance.

After applying the composition, it is possible to get a very smooth surface that does not need additional grinding. Such compositions are sold in finished form and do not need additional breeding water.

Polymeric -based putties are:

• Acrylic - with their help, both finishing and starting wall decorations are performed by a high level of plasticization, so they are able to fill small irregularities and eliminate defects, ready -made formulations are characterized by the lack of unpleasant odor, therefore they are used in the room for people with allergies, have a high degree of adhesion to surfaces made of concrete or wood;
• The latex composition - allows you to get a perfectly mirror surface, has high adhesion, therefore it is universal use on any type of surfaces, during operation they are not prone to cracking and shedding.

Before applying putty on the walls in the bathroom, it is necessary to prepare the walls. Initially, remove the old coating from them, evaluate the condition and depending on this, perform the following actions. If there are fungus or mold on the wall, you need to get rid of them using abrasive compositions. In order to remove the old plaster or putty, use the spatula, and the final cleaning will help sandpaper.

If necessary, in deformation of tiles from the walls, use a punch. After that, you should get rid of dirt and dust in the room. In the relationship with the main material from which the walls are built, evaluate them for the presence of cracks and chips, if necessary, plastered the walls.

Process the walls with a primer penetration, which will prevent the development of mold and fungus on the wall. We recommend that you prefer a primer on an acrylic basis. With its help, not only the mechanical strength of the coating will improve, but its stability before moisture increases.

Keep in mind that when removing the finish to the main part of the wall, you increase material and physical costs for repairing in the bathroom. Therefore, if the base is of good quality, it is not worth deleting it. In any case, first of all, it is necessary to assess the situation by conducting a visual examination of the walls.

The old plaster remains on the walls in such cases:

1. They are securely fixed on the wall, has no deformation, swelling, cracks. If tapping the wall, plaster is held tightly on it, it is not worth replacing it.

2. Remove the decorative coating without damage to the layer of plaster. Use the spatula to remove wallpaper or paint. Tiles are dismantled almost always with plaster damage.

If you are sure that during the plastering of the walls, all technological nuances were observed, then feel free to leave this layer on the wall.

To perform putty walls and ceiling in the bathroom, it is necessary to take care of the installation of the beacons, the interval between which is up to half a meter. To do this, use the laser level. The most convex point of the wall will be a guideline for determining the thickness of the putty. If there are cracks on the walls, set in their place the cut part of the glass chuck or a special mesh that prevents relaxation.

If the ceiling in the room will also putty, then start work with it. Prepare the composition for work, thoroughly mixing it. Small spatula apply putty to the corners and distribute it on the surface.

To facilitate the putty process, conduct preliminary leveling with the starting composition, and then apply the finish mixture.

The putty of the walls begins with the installation of the putty composition into the deepest cracks and defects. Calm the composition with a spatula and wait for its drying. Treat the wall with another layer of primer based on acrylic and continue to work. Keep in mind that the clutch of the finished putty composition with the wall depends on the quality of the primer. Apply the starting lineup and align the walls.

After drying it, grind the walls. Using a small half, apply the finish putty, the thickness of which should be minimal. To process a small room, use a spatula to apply putty. Wait for the composition of the composition and apply another layer of putty.

Drying walls should be carried out in the most comfortable conditions. Drafts should not be present in the room, and the optimum temperature is about 20 degrees. If putty has a cement base, then excessive humidity in the room will only strengthen it.

After the putty dries, the walls are prepared for staining. Please note that this process begins a few days after the final leveling of the wall. If you perform this process later, the cement composition acquires high strength, and it will be impossible to polish the walls.

Before starting work, put on protective clothes, a mask and a respirator. Since during operation a large amount of dust, irritating eyes and respiratory tract stands out. Fix the abrasive net on a manual or electric tool for leveling walls. It is possible to replace the grid with sandpaper with fine grain.

The plane of the walls is processed using circular movements. At the same time, follow the working process. Grinding is performed until there is no irregularities on the wall. To check the wall, use the level or rule. Next, you should get rid of the dust in the room and perform the primer of the walls. The primer improves wall strength and additionally fixes putty.

Further actions for wall decoration in the bathroom are associated with the implementation of their staining. For these purposes, you should also use compounds with moisture -resistant characteristics that tolerate temperature fluctuations well.
