Decorative plaster gives walls a distinct charm by fusing texture and design in a way that ordinary paint cannot.

Selecting the appropriate paint for ornamental plaster can be somewhat challenging. You need a product that enhances the natural appearance of the material while adhering well to its textured surface. Paint varieties vary in their ability to produce finishes, ranging from glossy to matte, each with its own unique appearance and texture.

It’s important to properly prepare the surface before painting. This guarantees longer-lasting and excellent paint adhesion. It is important to remember to clean the plaster, fix any damages or cracks, and apply an appropriate primer.

Once your surface is prepared, accuracy in paint application is crucial. Brushing, rolling, and spraying are some of the techniques that can influence the finished look. Every technique has benefits of its own, and the decision is based on the particulars of your plaster as well as the intended result.

Painting decorative plaster can completely change your room with minimal work and the appropriate technique, bringing out the special qualities of your walls and introducing a dash of individual flair. The correct paint can really make your decorative plaster stand out, regardless of your preference for bright or subdued hues.

Is it possible to paint decorative plaster and with what paint

When working with plaster mixture, white paint is frequently purchased. Any pigment can be added to it in the necessary amount.

The Venetian and Moroccan types of ornamental paint don’t require painting. The textured surface needs to be painted with the pigment. Many artisans tint the plaster in order to save time. Additionally, this mixture doesn’t require additional painting after application.

The question of whether decorative plaster can be painted over is one that has no definitive answer. Everything is dependent on the material’s constituent parts. But it’s best to clean the wall before you begin decorating it.

Paint for decorative paint – what to paint with (what is better to choose)

The composition to be used is determined by the intended use. Facade paints made of silicone, acrylic, or silicate are appropriate for outdoor use. They shield the plaster from the elements, such as wind, rain, and temperature fluctuations.

Latex- and water-based dispersion-based compositions shield walls from fungi and mold that pose a health risk to people.

Any kind of paint can be applied to both textured and smooth surfaces. Covering relief walls, however, requires 1.5–2 times as much material.

Tinting textured plaster with decorative paints

During repair work, plaster is frequently tinted because it is either white or light gray in color. You can make tiny chips and cracks invisible with this technique.

For tinting, several pigments are frequently used. It’s best to choose your dyes at a hardware store. It’s possible to discover exquisite color combinations by using a specialized application. Pigment mixtures are made at home with a mixer. Painting a test piece is advised. It should be noted that the plaster solution brightens by one or two shades, and occasionally by more, after drying. You must therefore apply more pigment.

Tools for working with decorative paint

The technique determines which tools to use.

  • plaster mix (can be replaced with putty);
  • paints and colors;
  • foam sponges;
  • brushes with different bristles;
  • mixer;
  • spray gun (for working with a large area);
  • pieces of fabric;
  • trays for varnish, paints and other compounds;
  • masking tape (to highlight work areas);
  • stepladder (when painting walls indoors);
  • scaffolding (for working with facades).

Textured paint can be applied like decorative plaster. Glitter and other ornamental components are also utilized.

Preparing the surface for painting

After the plaster mix is applied, the walls need to be thoroughly cleaned of any leftover dust and pellets. For flat surfaces, use a clean cloth. You can use a damp sponge to clean relief walls. Another option is to use a vacuum cleaner. After that, prime the wall.

  • improve the adhesion of plaster and paint;
  • fill small cracks in the coating;
  • prevent the plaster layer from spreading.

You must shield the floor, window sill, and other surfaces before you begin painting.

How to paint decorative plaster with your own hands

Novices ought to strictly stick to pre-made technologies. However, those who are skilled at painting decorative plaster by hand frequently mix different techniques for applying pigment.

Painting walls in one color on textured plaster

This approach is thought to be the most basic. It is appropriate for novice artisans. Strips up to 6 cm wide are painted onto the surface. Strokes ought to be straight. Paint leftovers need to be shaded. Horizontal strokes are possible if the surface is embossed.

Painting decorative plaster in two colors (mother-of-pearl)

When it’s necessary to lighten or darken the wall’s relief areas or depressions, this technique is frequently applied. When painting two colors on decorative plaster, mother-of-pearl should be added to the primary shade.

  1. If there are many depressions on the surface, you can first apply an additional color. For this, use a roller with a long pile. After the first layer dries, you need to apply the main color. It is advisable to use a sponge.
  2. A smooth surface should be painted in the main shade. You can use a spray gun or a wide brush. After drying, apply an additional color with a figured roller.
  3. When you need to emphasize protruding parts, the wall should be painted in the main tone. Additional color is applied to the bulges using a sponge or a narrow brush.

DIY technique for applying paint with a dry brush for walls

Texture is enhanced by the technique. The work is completed with darker tones painted in the nooks and crannies. The desired colorant is combined with white paint. It should be a bright shade. For this application, a roller with a long pile is appropriate. The surface needs to be entirely dry.

The second layer and the first layer share the same color. But the white paint has less pigment added to it, making the shade two to three tones lighter. The parts that protrude need to have the layer applied with a brush. A roller with a small pile can be used.

The brush is cleaned with a cloth or piece of paper before the second layer is applied. In this manner, the tool uses the least amount of dye. You can use metallic powder or mother-of-pearl for the second layer.

The method of working with two colors is comparable to this technique. The difference is that the painter starts working right away, without waiting for the decorative plaster to dry.

Removing paint to lighten interior walls

This method is limited to the manipulation of relief surfaces. The aim is to draw attention to the depressions. The textured plaster is painted in a single color to get the desired effect with the least amount of time and effort. A grinding machine is used to remove all protruding fragments after one to two days, aging the surface and giving it a worn appearance.

  1. Applying the main color. It is necessary to treat a small section of the wall with water-based paint.
  2. Cleaning the surface. The paint must be wiped off with a damp foam sponge. The color will only remain in the recesses.
  3. Applying an additional tone. This step is optional. The relief areas are painted with a sponge or a thin brush in a shade lighter or darker in relation to the main color.
  4. Applying a fixer.

The effect of Venetian plaster on the wall

Putty can be used to simulate natural stone, such as granite, malachite, etc. d. The Venetian plaster effect is the name given to this method. Sometimes it’s made with stone chips. However, because it is a costly material, gypsum plaster that has been painted the appropriate color frequently takes its place.

  1. Preparing the coating for work. This stage includes cleansing and removal of minor defects.
  2. Applying the base layer. A long-haired roller is suitable for the job. Additionally, a narrow brush may be required, which is used in hard-to-reach places. You need to wait until it dries.
  3. Application of decorative coating (gilding, bronze). Inexpensive aluminum powder is often used to create a “silver” tint. The decorative layer can be applied with a short-bristled brush or foam roller. The touch should be light and the pressure should be insignificant. If the technique is followed, the first layer will be visible from under the second.
  4. Consolidation. At the final stage, a water-based varnish is applied to the coating. Since this substance can create a crust, it must be diluted. Water should be no more than 20-30% of the total volume. Apply the varnish with a foam roller.

Marble wall

The technique works on both textured and smooth surfaces. You can use it to look like marble. White paint is mixed with gray color and then sprayed onto the work surface. For this, a roller is employed. You can apply the "dry brush" technique. A portion of the surface ought to stay unpainted, either entirely or partially.

The second layer’s composition contains less pigment. For work, it is best to use a different roller. Not only can you paint over bare patches of the surface, but you can also cover areas that have previously been painted a darker shade. You can begin working before the top layer dries.

After two to three days, thin brush strokes are used to paint the marble veins. To create the appearance of unpolished stone, the surface is either matted or covered with acrylic varnish.

Using fabric

Paint made with water is mixed with pigment to achieve the desired color. Using a brush or a roller with long hair, the final mixture is applied. Wet a piece of cloth (at least 30×30 cm) with cold water and squeeze out excess moisture. After that, it needs to be folded up and fastened to the roller. Make sure you finish this before the paint dries. Using a soft brush with long bristles is how shading is done.

Once the first layer has set, you can start applying the second layer by following the suggested method. To achieve a more natural appearance, consider altering the shade by making it either lighter or darker.

You can thin the paint for the second layer by adding a tiny bit of mother-of-pearl. It is advised to work with a portion of the wall that is no larger than three square meters in one session.

How to repaint decorative material

It is not necessary to clean decorative plaster of its previous color before repainting it in a different hue. It is acceptable to use a white primer with an acrylic base if removing the previous layer is not feasible. There is no loss of texture. You can begin painting after it has dried. A primer may not always be used. For instance, applying a layer of mother-of-pearl glaze to Venetian plaster is sufficient to lighten the material.

How to remove old decorative paint

Experts recommend scraping off the previous putty layer. It must be wet with warm water and left for one to two hours in order to accomplish this. A steam generator is one option. Next, abrasive materials are used to remove the previous layer. The walls must dry before doing any more work.

Applying paint to ornamental plaster is an excellent method to improve its look and safeguard the surface. Select the proper paint type, like latex or acrylic, which are renowned for their flexibility and durability, for the best results. To make sure the paint sticks well, start by priming and cleaning the plaster. For smooth finishes, use a brush or roller, and think about sealing the surface for additional security. This procedure prolongs the life of your plastered surfaces while also improving their aesthetic appeal.

Wax on plaster

  1. Synthetic. Such wax has water-repellent properties, is resistant to temperature changes. Synthetic wax can be applied with almost any tool.
  2. Gel-like. Compositions are applied with rubber spatulas.
  3. Liquid. Wax is used for any type of surface. It is advisable to apply it with a cloth.

Decorative plaster is painted in its final stages using compositions containing wax.

  • enhance the brightness of the color;
  • give a glossy shine;
  • protect from moisture;
  • deepen the relief surface;
  • change the color of Moroccan or Venetian plaster walls.

It is possible to add glitter or pigment to the wax. In this instance, the homogeneity of the composition requires constant stirring. It is possible to rectify the wax layer three to four hours after application.

Glaze

Both smooth and relief surfaces can be coated with the glaze composition. Both internal and external work is done with it.

  1. It is necessary to shade the joints immediately after applying the glaze composition.
  2. The surfaces should be covered with the material in small strokes. For this reason, working with the compositions takes a lot of time.
  3. Before applying the composition, you need to put on special gloves. If a person feels dizzy or suffocated, it may be necessary to protect the respiratory system.
  4. You can work with the compositions at a temperature of at least 10ºС.

Varnish

The material resists mechanical damage and moisture. It’s applied to matte surfaces to add luster. Water-soluble acrylic varnishes are employed in room finishing. It is possible to create artificial cracks with crackle varnish. Organic solvent compositions are used when working with facades.

You can add glitter or dyes of your choice to the varnish before using it. Use a foam roller, sponge, or brush to apply the coating in a single layer after it has been well mixed.
