General information about glazing compositions

Use a universal glazing composition for decorative plaster if you need to draw attention to the wall’s texture and add more color and gloss to the surface. It can be applied to facade plastering as well as indoor use. This composition’s technology allows for quick drying of the layer, which, in contrast to other paints and varnishes, strengthens completely in 3–4 hours.

Why paint over decorative plaster

Although decorative plaster is thought of as the last layer, artisans frequently paint, glaze, or apply glazing varnish over it. This is done to guard against the damaging effects of outside factors in addition to adding shine. This kind of plaster treatment offers strong defense against fading, moisture, and mechanical impacts.

Advantages and disadvantages

• difficulties with repairing damaged areas, since professional skills are required to fix them properly;
• high costs.

• high strength of the decorative coating;
• resistance to sunlight, protection against surface fading;
• increased resistance to scratches, impacts, abrasion;
• giving additional strength to the decorative plaster coating;
• the possibility of using detergents to clean walls;
• harmlessness and environmental safety of decorative glazing varnish for plaster, made with water;
• uniform laying on both flat and embossed walls;
• the ability to remove the spraying varnish with a solvent.

How to paint, the choice of materials and tools

.. Although the composition is primarily meant for wood processing, plastered surfaces can also be processed with it. Additionally, this glazing varnish dries quickly and forms a robust layer on plaster that is resistant to high humidity. The expensive price and the product’s feeble alcohol resistance are two drawbacks.

Brushes of various sizes are the primary glazing accessories.

• painting brushes;
• fabric flaps;
• spray gun;
• protective adhesive tape for covering the joints of walls and nearby structures;
• rollers with rounded edges;
• sponges used to remove stains.

Processing large amounts of glaze in both vertical and horizontal directions requires the use of wide brushes.

If the wall surface has semicircular patterns, circular movements should be made to more fully impregnate the decorative plaster.

Technology for painting a finished surface

For ornamental walls, it is advised to apply the subsequent coat of paint only after the preceding one has fully dried. The glaze takes four hours to fully dry at room temperature; occasionally, the process takes up to twenty-four hours. Paint can take up to 48 hours to dry if the temperature is close to zero and the humidity is high.

Surface preparation

Painting over decorative plaster makes the wall as smooth as possible and reduces the risk of damaging the final layer. This makes the task much easier to complete. Make sure the plastered wall has dried completely and that the surface has solidified before applying glazing. Next, remove construction waste and use a damp cloth to wipe off the grout dust. While additional wall priming is not required, some experts do this task as well.

The best indicators for glazing varnish application on plaster are thought to be a temperature between +5 and +35 °C and a humidity level of no more than 75%.

It is advised to put off painting if these circumstances do not exist. Allow the space to air out and wait for the ideal temperature to be reached before glazing the walls.

Painting

It is best to cover adjacent surfaces with masking tape around the whole perimeter before beginning to glaze the walls with the prepared composition. The wall won’t get dirty if the master unintentionally goes over the edge, and the tape will be taken off once the job is finished. You end up with a paint job that is even and doesn’t interfere with the walls next to it. Applying a film to the floor covering is required to shield it from varnish.

Using a roller to process a decorative wall is similar to working with ordinary plaster. This can be accomplished by thinning out the paint in a tray to the appropriate consistency, dipping the roller into it, scraping off excess paint with the tray’s grooved area, and painting the wall. Movements should be made from top to bottom first, then in the opposite direction.

It is evident from the surface of the walls that uniform application of the decorative glaze composition can be achieved with just one roller. This method can be used for straightforward textured solutions; however, other methods must be used for intricate, complex reliefs. You will need a brush for this that is easy to use to create strokes of various lengths and directions. This will help break up the monotony of glazing, particularly if there is already a decorative pattern on the surface.

When applying paint to a wall, it will be more accurate if the brush strokes are directed in different directions. Then, you can use the roller’s vertical action to level the surface. Combined, these two instruments are frequently employed to apply the "rain" technique to the relief. Any crevices, corners, and difficult-to-reach areas are easily penetrated by the brush. Then the relief areas are painted using minimal glazing composition and light roller pressure. This process yields a coating that is two colors.

A sponge and mitten are used if the texture is fine, which highlights the effect of antiquity and deepens the relief. Occasionally, they enlist the aid of a spatula to apply an extra coating of ornamental glaze. However, this tool is more frequently used to clean the wall of extra paint. Joints should only be worked on when wet, requiring a specific technique that requires two hands when carried out by two masters.

Wearing rubber gloves and protective clothing is advised when applying decorative plaster compositions to walls, even though they are safe and friendly to the environment. If a blur effect is required, carefully draw a wet sponge along the wall, soaking the composition where it needs to be soaked, to achieve the desired effect.

Novices might encounter several challenges during the finishing process, and errors might arise that require fixing. Here, the layer is replaced and the damaged area is sanded.

Calculation of consumption

Decorative plaster glazing varnish should be applied in accordance with the intended outcome. One layer should be sufficient if only light coverage and protection are needed. The color scheme’s brightness is improved with the next one. You can use a different color scheme or the same tone. For every square meter, about 100 g of the composition are used. Switching from a brush to a spray gun results in a slight reduction of varnish.

Why you need to use wax and what types are there

The most common use of wax is in plaster imitations of natural stone. Both natural and synthetic materials can be used. The first choice adds a long-lasting matte finish, while the second adds gloss. Wax doesn’t always have a clear color, but certain toners can give the material the desired hue.

Only a transparent version of Venetian plaster is appropriate because it highlights all of the subtleties of the material. If it’s necessary to alter the coating’s tone, use colored wax; a material with a gold or silver tint is advised for a brighter effect, simulating gilding or metal coating.

Waxing for protection and shine

Wax is required to give the coating smoothness and gloss while shielding it from moisture. It makes no difference how the plaster is applied. Use a sponge, spatula, or soft material, depending on the composition’s thickness. The most important thing is to apply the wax completely, rubbing in circular motions until the surface shines. It is advised to check the wall beforehand for any flaws, as they will be very difficult to repair afterwards.

It’s also critical to remove any dust or crumbs carefully because they can scratch the surface when they come into contact with the cell. Experts who enjoy using this tool produce a remarkable sheen that is unattainable with mittens or sponges. Working from one corner to the other without using the layering method is required. Even though the composition dries out quickly, any flaws can be repaired in three to six hours.

Keep in mind that the screening dries out earlier at the edges. The other day, polishing is done with the use of a grinding machine or cloth.

Adding a glazing composition to your decorative plaster will make your walls much more visually appealing. By adding depth and richness, this method turns boring surfaces into sophisticated, visually arresting elements. You can improve the overall aesthetic of your space and get professional-looking results by following the instructions provided in this guide.

The secret to success is preparation. Before beginning, make sure the plaster surface is clean, dry, and devoid of any flaws. You can also avoid unpleasant surprises by taking your time when mixing your glazing composition and testing it on a small area before applying it to the entire area.

Even though it’s simple, the application process calls for patience and close attention to detail. You can achieve a smooth and even finish by using the appropriate tools and techniques. In order to prevent obvious lines and streaks, always work in tiny sections and blend as you go.

After applying the glazing composition, give it time to fully dry before assessing the finished appearance. To improve the effect, you can add more layers if necessary. You can add a sophisticated touch to any room in your house by mastering this decorative technique with patience and practice.
