DIY decorative plaster
What to do if you are tired of the usual wallpaper or panels as wall decoration? Indeed, despite the variety of options, I want to design a unique design that reflects the individuality of the owners. If you have enough patience and strength, creating a surface with decorative plaster with your own hands is an excellent solution for the interior of any room. Today we will show you how to do it.!
Advantages and disadvantages of decorative plaster
Many people, even those who have never done renovations, have heard of plaster – a paste with a specific composition that is applied to the wall and is often used as a base. So, the decorative variety has little to do with this gray mass. It is used as a finishing material, helping to create aesthetic, textured walls with an unusual pattern..
The main advantage of decorative plaster, which distinguishes it from other, easier-to-implement options, is its uniqueness. The same person cannot create two walls with an identical pattern. In addition, using different application methods, it will be possible to achieve the effect of imitating marble, granite or other interesting coatings. Some masters get real artistic compositions, but even with a simple application, the plaster looks quite impressive.
After the paste has been applied and hardened, it undergoes a color that revitalizes the monochromatic surface. Plaster is a very practical finish that helps hide some wall imperfections, such as cracks or slight irregularities. At the same time, in combination with a high-quality primer, it can play the role of a good heat insulator.
Few modern materials on the construction market can be called safe for health. But just not decorative plaster – it has an ecological, harmless composition, and therefore it is suitable for many rooms, even for a nursery.
Of course, applying the mass requires a certain skill and accuracy, but they are achieved after a little practice, as well as a detailed study of the instructions. Another difficulty in using decorative plaster is the high requirements for the walls. They should be as even and smooth as possible, and for this you will have to first prepare the surface.
Types of decorative plaster
Plasters are of different types, depending on the desired properties and the effect after application. Allocate a classification by composition and filling, the first of which includes the following options.
Mineral decorative plaster
It is made from cement and sold dry. Add water to the product, stir thoroughly with a mixer. This decorative plaster is suitable for mineral primers and creates a variety of reliefs. Another plus is the low price, although you can find different options. But such a solution is not very reliable – it is easily damaged by the slightest vibration or careless handling..
Acrylic decorative plaster
More reliable decorative plaster, which contains an aqueous dispersion of acrylic resins. It can withstand temperature extremes, high humidity and is easy to clean with common cleaning agents. Great news for owners of uneven walls – the mass is applied without preliminary preparation and dries quickly enough. True, it costs much more than the first type.
Silicone decorative plaster
A more modern look that immediately attracts attention with its high characteristics: elasticity, durability, easy care. Easy to apply, even a beginner can handle it. This decorative plaster is sold ready-made, in a varied color palette, the shades of which can be mixed directly during use. You will have to pay a lot of money only for modernity and quality..
Classification by type of filling
Various components are added to the basis of the mass, which allow you to achieve a certain decorative effect. Based on this, there are three most popular types of plaster..
This is a heterogeneous granular mass with particles of granules, pebbles, fibers or other elements, made on a mineral basis. Flexible and pliable, easy to apply with any tool to create the desired texture.
It is better to give preference to a product with an aqueous solvent, since synthetic ones have a very pungent odor, which complicates repairs indoors.
Another plus – decorative structural plaster is sold ready-made, does not require additional mixing with other ingredients..
The so-called compounds that help create a relief surface texture. With special skill, you can imitate wood, crumpled paper, stone – the initial result depends on the application technique, as well as the tools. The main component of the product is lime flour, various types of crumbs, fibers. Polymer materials enhance the embossing effect.
This is a kind of decorative plaster with an unusual, transparent structure, made of marble flour, water emulsion and hydrated lime. Creates the illusion of marble stone, and the surface itself can be painted in any color, combining them for a mosaic effect.
In addition to decorative properties, Venetian plaster has practical advantages – water resistance, environmental friendliness, odorlessness, long service life. Only when applying, make sure that the surface of the walls is perfectly flat.
Decorative plaster in the interior
Decorative plaster is a versatile solution that suits many spaces and styles. It is traditionally believed that walls with such a finish are created for a classic interior, but the variety of types allows you to fit the element into a more modern design..
Combinations of plastered walls with other finishes look great. For example, structural decorative plaster and wallpaper, a surface with a deep relief and plain smooth partitions. Due to its environmental friendliness, the material is suitable for the kitchen, living room, bedroom, hallway. But for the bathroom, it is recommended to use waterproof varieties or completely avoid applying.
The use of decorative plaster in Provence will only emphasize a certain simplicity, negligence of the room, and in the loft – rudeness and brutality. For a classic interior, it is recommended to create a more complex composition of patterns, painting in a noble warm shade.
Preparation of walls for decorative plaster
Prepare the walls before applying decorative plaster. To begin with, you should remove the old coating with your own hands, be it wallpaper or paint. Spatulas, solvents, plain water, as well as a construction hair dryer will help with this..
The bare wall should be cleaned of all traces of work with a detergent. After these procedures, surface imperfections, such as cracks, which are best leveled with a primer, may open to the eye. Some types of decorative putties can cope with minor defects, but the Venetian one requires perfect walls.
But in any case, you cannot do without a preliminary primer. It helps to repair micro-cracks and prevents absorption. It should be borne in mind that each type of plaster involves its own primer, as indicated in the instructions. In this case, surfaces with metal parts must be treated with a protective agent so that they do not rust over time..
Methods for applying decorative plaster
Depending on the type of decorative plaster you choose, its preparation may differ. The dry version will have to be diluted with water in the specified proportions, the ready-made one will have to be removed into a convenient container. The finished solution is evenly applied to the wall with a spatula, and only after it has set, start creating the pattern. To do this, use a variety of tools: floats, rollers, stamps, brushes, even leaves or hands. Literally any item will do – the main thing is that the result is satisfying to you. At the same time, the thickness of the initial layer directly depends on the complexity of the drawing..
It is recommended to start from corners where the first irregularities will not be so noticeable – after a little practice, the technique will quickly improve. Most likely, there will be no time for rest – as the mass gradually solidifies. This will start in about 20 minutes, and by this time you need to go through the finishing with a trowel, smoothing the relief. The layer will completely dry out in about a day. After that, you should walk with a fine sandpaper, giving the wall a complete neat look..
Painting decorative plaster
The need for additional painting arises mainly with mineral decorative plaster, since the rest of the options are sold in a certain color. To make the paint last longer, you can pre-prime the surface. Note that we are talking about a dried mass, which is completely ready for subsequent manipulations..
It is recommended to use waterproof paint and a wide nap roller. You will most likely need a double application, perhaps an even richer shade for more effect. At the same time, various combinations, mixing or application over a complex pattern are permissible. The finished result must be fixed with a water-based varnish.
