What properties should putty for a bathroom have?

First of all, let's understand what is putty? This is the finish coat that is applied before the final finish to create a perfectly even and smooth surface. The main purpose of the putty is to eliminate minor defects and cracks. More serious irregularities must first be repaired with plaster or drywall.

Regardless of what you will finish the bathroom in the future, the leveling layer should have the following characteristics:

• Moisture resistance. The bathroom is a room with high humidity. The coating should not break or peel off under the influence of moisture, even over time.
• Durability. The service life of such a coating without loss of quality should be long.
• Resistance to temperature extremes. Temperature differences should not lead to deformation of the putty layer, otherwise - the lining will not stay on it.

These are the main criteria by which you need to choose a composition. All other characteristics depend on your individual needs and further cladding.

Types of putty based on raw materials

By the type of the main component and the purpose of the putty for the bathroom for painting, there are the following types.

Cement

One of the main advantages of this type of mixture is its high resistance to moisture. Therefore, they are recommended for use in the bathroom. The cost of such material is within reason, and the characteristics are quite high.

Important! Due to moisture putty becomes even stronger. But such a composition dries slowly and shrinks.

Polymer

At the moment, these are the most advanced developments, which, of course, affects the price. The surface is very flat and smooth. This putty is plastic and easy to use, does not shrink.

Putty on a polymer basis is of 2 types:

• Acrylic - has a high level of plasticization, so it can fill in small bumps and defects. The composition is odorless, has a high degree of adhesion to surfaces made of wood or concrete.
• Latex composition - allows you to get a mirror surface, not prone to cracking and shedding.

Gypsum plaster

Gypsum mixtures are not suitable for the bathroom, as they are not able to resist the concentration of hot steam, not to mention possible leaks from above.

Oil-glue

One of the first putty powders, which is considered obsolete. The quality of work with such a composition is very low. Therefore, it is mainly used for utility rooms that do not require high-quality decoration.

Types of putty as intended

What is putty for a bathroom for painting? We are looking for a special marking on the packaging that the mixture is suitable for use in the bathroom. Then we select one of the options, since depending on the purpose of the putty, they are divided into:

• finishing putty, which is most often sold in finished form and is used for the final decoration of walls;
• leveling putty, which is used for the initial leveling of walls or ceilings;
• universal putty allows both alignment and final finishing.

Important! Before applying any mixture, regardless of its composition, it is necessary to cover the walls with a primer, which provides adhesion of the surface to the material. In addition, it performs an antiseptic function.

Mix release form

Depending on the readiness of the material for use, there are two types of putties:

• Dry mix - dilution will require water. Such mixtures quickly harden, so they need to be prepared in small portions.
• The finished composition is more expensive, but at the same time more convenient to apply. The shelf life of such a composition is quite large; over time, it does not lose its quality characteristics.

Important! If you have not had experience in repair work, but you want to do everything yourself, in this case, choose ready-made mixtures. So there will be less risk that you will do something wrong.

Putty and painting the bathroom

If you decide how to putty the walls in the bathroom for painting, you can not just apply the composition and align the walls. First you need to prepare the surface.

Surface preparation

In order for the coating to hold firmly and not to deform over time, the surface must be cleaned and primed. For this:

• First you need to remove the old coating layer from the surface. If there are bumps, they are knocked down with an ax or cut off with a grinder. After that, the walls are cleaned with a solvent from greasy stains and a damp cloth from dust and dirt.
• If the surface is severely damaged, then it must be treated with cement plaster, which will fill all major cracks and defects.
• Then you need to treat the walls with an antiseptic so that the fungus does not appear.

Important! If the surface is wet, it must first be dried. If there are traces of mold or mildew, they must be cleaned with a wire brush and burned with a blowtorch.

• Now the walls can be treated with a primer, which will fill all pores and microcracks, strengthen the surface and ensure its adhesion with a subsequent layer of putty.

At this preparatory stage can be considered completed, it remains only to wait until the primer layer dries.

Surface alignment

If the putty is made from a dry mixture, then it is prepared before application. Remember that it dries quickly, so dilute a small portion. It may take several layers of putty for the bathroom to be painted.

Important! You can not putty with a thick layer - it will stick poorly and crack.

Getting started:

1. We fill in the solution with all the recesses, cracks and joints. We wait for drying, skins and apply a layer of primer. Now you can apply a leveling layer or several layers.
2. Ideally, after drying, each coat should be treated with a primer. But in practice, the primer is applied only before the finish. For this, a special putty is used - less granular and more plastic.
3. Before applying the finishing putty, the surface must be carefully sanded. All splashes, sag removed. The thickness of the finish layer should not exceed 1 mm.
4. The finishing layer of the putty of the walls in the bathroom for painting should be perfectly even and smooth.
5. During drying, drafts should be avoided, the temperature should be about 20 degrees. The solution dries about 14-18 hours.
6. When the putty is completely dry, it must be removed from the abrasive components, and you can paint the bathroom.
7. Paint is best applied in several layers and add antibacterial additives to it.
