Surface painting is both a complex and simple operation. Even a novice can cope with painting. But the further result will already depend on whether he knows the technology. To get a high-quality and beautiful surface, you need to understand what material is suitable and in which cases it can be used. Today we will present an overview of the plaster paint for interior use. Description of types and application rules - below.
Polyurethane and epoxy paints
This is a great option for work on plastered surfaces. These types of paints do not require preliminary preparation of the walls. Usually available in double packaging. To achieve a better result, you need to mix them. Proportions are always indicated on the package.
What do the reviews say about the Tikkurila paint for interior plastering? She is pretty high quality. The product reliably protects the surface from damage in the future.
Tikkurila paint can be used in public and residential buildings. It is applied on cement, concrete, plaster, brick surface or on cement-lime plaster. Also suitable for drywall sheets and chipboards.
Another feature of epoxy and polyurethane paints is their fast drying time. According to reviews, such a composition dries out already three hours after application. But the final "grasp" occurs only after a week. Only then can the surface be decorated with a pattern. This is not necessary, but many so decorate the room. As a result, the design is bright and original.
If we talk about the shortcomings of such paints on plaster for interior work, reviews note the high cost. And the more unique the texture and shade, the more expensive the material. But you need to consider that by acquiring such a paint, you can get good surface protection. After all, the composition is not afraid of aggressive chemical influences.
Emulsion
Plaster for walls can be combined well with emulsion paint. It is considered one of the best plaster paints for interior use. Moisture-resistant enamel combines polyphenols and acrylics. Thus, the product penetrates perfectly into the pores of the plaster and forms a reliable protection. Paint dries too quickly. Reviews say it will take about four hours. In addition, the composition is not harmful to the body. It is easy to wash paint off the skin using warm water and soap.
But before using emulsion paint for internal work, experts recommend treating the plastered surface with detergent. Thanks to this, we neutralize the alkali. The paint will be firmly and firmly held.
There are several types of these formulations:
Which is better to choose? Experts say that it is better to give preference to matte enamels. They are more resistant to abrasion. In addition, the glossy composition does not have such resistance as matte. The washable plaster paint is mainly used for interior work. Additionally, surface decoration is possible. For example, painting on raw plaster looks original.
The texture of emulsion paint can be different:
The first type looks attractive on the wall, but can crumble over time. Therefore, such a composition is not recommended for use in places where there will be frequent contact with anything. Acrylic paints for interior rough plastering are very durable. They do not crumble, like their counterpart. However, there is a big minus. Due to the rough texture, such paint constantly attracts dust. To make the wall less contaminated in the future, the surface is additionally treated with a conventional water based emulsion.
Please note that the consumption of textured emulsion paint is quite large. If you intend to finish embossed walls, you need to buy material with a margin.
Non-drip paint for the ceiling
If you plan to finish the ceiling after plastering, you can consider purchasing special paints. In its composition, it is similar to emulsion and alkyd analogues. However, jelly is additionally added here, which makes the solution thicker. Thanks to this, it is much easier to carry out painting work on the ceiling. The paint will not drip down, but will be evenly distributed over the entire surface. But you should always pay attention to the instructions. The plaster paint for interior use should not shake and mix before use. Otherwise, its structure may deteriorate.
Before performing paint work, all nearby surfaces must be protected. If inadvertently paint gets on an unnecessary area, then it will be very difficult to remove it later.
Latex
Usually they are used for wallpaper. But they are also used on plastered surfaces. Such paints have excellent washing ability. But they have low vapor permeability. Mainly used in educational and medical institutions.
Technical characteristics of latex paints
Consider the technical characteristics of paints for interior use on the example of Dufa Mattlatex. It is a matte latex paint that is used to create wear-resistant coatings. It can be applied on:
- Stucco.
- Putty.
- Drywall.
- Structural wallpaper for painting.
It is made in buckets with a capacity of 1, 5 and 10 liters, color - white, thinner - water. Its composition should be no more than 10%. This paint is stored and applied at temperatures not lower than +5 degrees Celsius. Withstands up to 5 thousand cycles of abrasion. The layer dries after 4 hours. One liter of paint is enough to process 6.5 square meters of the wall. Density - 1700 grams per liter.
By the way, there is another paint from this manufacturer. This is Dufa Wandfarbe. By its properties it is a water-dispersed paint. It is used on surfaces with low operational load. Cleaning and repair repainting is allowed. Used both on walls and ceilings.
Density - 1500 grams per liter. The diluent is water. Material consumption - one liter per five square meters. It is produced in containers of 2.5, 5 and 10 liters. The degree of gloss is deeply matte.
What else to look for?
Special attention should be paid to those paints that can not be used for decoration inside the house. This applies to the composition of the alkyd and oil type. In addition, hairiness and cracks appear in many areas. It is also not recommended to use:
- Metal.
- Fireproof.
- Paints for wood.
The latter can be used only for taps and pipes. After staining, they will become shiny. Refractory facade paint for interior plastering is also not suitable. It can only be painted on a brick wall.
What to choose?
Experts advise using these types:
Their plus is that the wall does not need to be additionally prepared, unlike similar paints on plaster for interior work. The composition well fixes the plaster layer, but you need to work with it carefully. Unlike water-based emulsion, such paint can harm the body. Therefore, personal protective equipment is indispensable.
The nuances of painting
You should know a few nuances:
- It is necessary to start applying paint on the plaster for internal work after the plaster layer has finally dried. This will take at least two days.
- Although the material does not require preliminary surface preparation, it is recommended to treat the wall with soil. So the surface will be easier to accept paint.
- To apply the composition, you can use a brush, but it is more convenient to use a roller.
- Rubbing plaster with a sponge is allowed. This allows you to make a play of colors or create a unique pattern.
How to decorate such a surface? First, the wall is painted in the base shade (light) with a long-nap roller. Then wait a few hours for the base coat to dry. On top of it, a darker enamel is applied in a small amount. Following these rules for applying paint for internal plastering, you can get a visually more voluminous surface. If there is no need to apply dark paint, you can use metallic. This is an imitation of gold, bronze and silver. It is applied by dry brush or with a special mitt.
Application Rules
It is worth knowing how to use the paint correctly for interior work on plaster. The final result will depend on this. The work is carried out in several stages:
- After applying a layer of plaster and its drying, the wall is primed in two or three layers.
- Wait time until the primer dries. It will take another two days. At this time, you can do the purchase of paint.
- The method of application is chosen - with a brush or roller. Some use spray guns for application. It is fast and convenient, but you need a specialized tool.
- The paint is applied in two layers. First, a light layer is made - the base. If this is a spray gun, you can not stay for a long time in one area, so that there are no streaks. Then a thicker, base layer is already applied. But here it is also important not to overdo it. Stains significantly spoil the appearance of the wall.
- A small part of the metallic is applied to the protruding places.
- Wait time until the paint dries. Depending on the type, it will take about three to five hours.
- Using a spray gun, a protective varnish is applied.
Can facade paint be used for interior work?
Experts give a positive answer. Decorative plaster is painted:
- Silicone.
- Acrylic.
- Silicate.
- Other water based paints.
But first you must definitely clean the surface. Oil stains and dirt should be avoided.
Recommendations
Experts give some useful tips:
- Weatherproof paint is more suitable for outdoor plastering.
- If there is no specialized primer for cracked surfaces, polyvinyl acetate paints can be used.
- Since structural plaster has granular-like additives, you can immediately add color to the mixture.
Conclusion
So, we found out what types of paint are for interior work on plaster and how to apply it correctly. Summing up, it is worth saying that now only polyurethane and epoxy paints are mainly used. Since it’s easy to work with them, it makes sense to overpay a little. As a result, we get a quality result.
