Decorative roller plaster

Decorative roller plaster is an excellent method for creating textured, beautiful surfaces out of regular walls. This technique, which differs from traditional plastering, uses a unique roller to create patterns and designs, which makes it a great option for giving any space some personality. Decorative roller plaster can easily achieve any desired finish, be it sleek and modern or rustic and vintage.

The range of textures you can achieve when plastering with a roller is one of its greatest benefits. The options are practically limitless, ranging from delicate, wavy patterns to striking, elaborate designs. You can customise the finish to fit your style and the ambiance of the room thanks to the roller’s ability to imprint various textures.

This method is useful in addition to being aesthetically pleasing. Older surfaces benefit greatly from the added texture, which can help conceal wall flaws. Furthermore, because it’s a fairly simple process, both professional plasterers and do-it-yourselfers can accomplish it.

Decorative roller plaster is a unique way to add flair to your home’s interior design. You can create a polished finish that gives any space depth and personality with the correct supplies and a little practice.

Roller mixture and its features

What distinguishes this type of plaster from others? First off, the filler in the mixture is one of its key compositional features. This is why it is labeled as decorative with a bark beetle effect. Round marble chips and quartz sand are used as filler.

There are three varieties with varying marble chip sizes:

• large – grain size 2-2.5 mm;
• medium – grain size 1.5-2 mm;
• fine-grained — grain size 1-1.5 mm.

Coarse-grained mixtures are used to finish lobby walls, office walls, and facades. Walls in medium-sized and smaller spaces are decorated with fine-grained materials.

It uses just two kinds of bases: gypsum and acrylic.

The elasticity of an acrylic resin base is high. It can be used both inside and outside the house because of unique additives. Because acrylic resins are flammable materials, it is best to avoid placing compositions—even those with fire retardants—near locations where fire is used. Because of its poor vapor permeability, it is not a good choice for living rooms and bedrooms. Simple to maintain. Adapts well to changes in temperature and intense precipitation. resistant to frost. Mixtures can be made in different-sized buckets. One can buy a pre-made composition that has already been tinted. Its selection of colors is still limited, though.

Gypsum is a binder in decorative plaster used in gypsum rollers. offered only in dry mix form. Because gypsum-based composition is more susceptible to different kinds of vibrations, it is not advised to use it in newly constructed homes until the house settles, in areas with erratic seismic activity, or close to railroad lines. Interior spaces are the best places for gypsum plaster. It complements gas block walls well and "breathes" more effectively, helping to create the ideal microclimate. Not flammable and lightweight. Not advised for facades, damp rooms, or unheated areas.

This kind of coating has a number of advantages, including good noise reduction, heat insulation, and low weight. The 10-year guaranteed service life is the same as that of other mineral and latex finishes. The impossibility of local restoration or repair is a major drawback. It will be necessary to scrape off all finishing.

Required tool

The application of roller plaster doesn’t call for a lot of tools or specialized equipment.

Use the following for its application:

1. trowel,
2. wide spatula,
3. a plastic float is needed to form patterns.

Painting instruments are also widely used:

You’ll need clean rags, masking tape, and containers. To prepare and color the solution, a mixer is required.

Preparing the walls

Wall preparation involves both filling in cracks and leveling the surface of the wall, even though roller plaster can conceal minor imperfections in the base. To guarantee the required adhesion, oil paint that was previously applied to the wall must be removed.

Base preparation sequence:

• the wall surface is inspected,
• cleared of old coating residues,
• removes oil stains,
• Mold areas or areas of fungal infection are disinfected,
• checking the evenness of the wall and its verticality,
• if necessary, cracks and large gouges are repaired, and the wall is leveled with sand-cement mortar,
• primed in two layers – a primer suitable for deep penetration wall material (first layer) and a primer with quartz sand (second layer).

When the wall has dried completely, it is ready. It might be necessary to add color to the primer in order to achieve the desired color effect because roller plaster is a decorative plaster with a particularly thin layer in the grooves.

Application technology

Everyone remarks on how simple it is to apply this finish. Plastering, especially decorative plastering, is something that even non-painters can do.

As with anything new, you should start with practice on some drywall.

There are two phases to the work:

1. applying the composition in an even layer,
2. applying a pattern.

It is preferable to work in pairs because both gypsum and acrylic compositions set quickly and cover a large area. One person applies a layer of plaster, while the other applies a pattern.

You must keep in mind that fixing this kind of coating’s shortcomings is difficult. The entire layer needs to be removed from a spoiled surface. As a result, it is crucial that all tasks—preparation, solution dilution, and coating application—be completed in accordance with the technology.

Only dry weather with a minimum temperature of 5 °C and a maximum temperature of 35 °C is suitable for outside work. After applying the treatment, the wall has to be shielded from any potential rain as well as from direct sunlight.

Pour the recommended amount of water into a clean container to create a gypsum-based solution. More than 12 °C should be present in the water. After adding color and stirring, pour the dry mixture into the container. Stir the mixture again and add a little water if it’s too thick. Use a mixer to stir the mixture, then let it stand for ten minutes before stirring it once more. Before using, the completed acrylic solution is also stirred and, if needed, painted.

Apply a uniform layer of decorative mortar first. To do this, a trowel is used. The thickness of the layer is adjusted to match the grain diameter. The layer is given some time to set.

Roller plaster is a common tool for creating patterns like bark beetles. Using a plastic trowel, big, rounded grains are rolled out on the base to create it. The seized solution has grooves from rolling grains that are partially exposed by the mortar mass. A plastic trowel is used to apply a pattern by placing its working surface on the layer and moving it in the desired direction. Pressing down with the trowel is not necessary as this could ruin the coating.

In a strict sense, the patterns that result from rolling the grains of a roller structure include the bark beetle pattern. Because of the effect’s popularity, bark beetle is now more commonly used to refer to roller plaster than roller plaster itself. These grooves are actually erratic, arcing or winding, resembling the passageways that beetle larvae gnaw through. This pattern is unrelated to other patterns like concentric circles, rain, or rugs. Similar to each other, they are applied by rolling the trowel, but the movements’ directions depend on the order.

1. Rains are obtained by parallel straight wires of the trowel vertically or at an angle.
2. Mat — alternating short cross-shaped movements.
3. To apply concentric circles (lamb) the trowel is rotated around the center of its working surface. Strictly speaking, these are not exactly circles, but their likeness.

Following pattern application, the mixture is let to stand for 30 minutes, and the pattern is then smoothed using a dampened, clean stainless steel trowel. Sharp protrusions in the dried coating are then removed with sandpaper. The surface is then cleared of dust.

With little effort, decorative roller plastering is a flexible and user-friendly technique that lets you create gorgeous textured finishes on walls. Plaster is an excellent choice for anyone wishing to add character and depth to their space without needing sophisticated skills because it can be applied in a variety of ways, from subtle to bold. Decorative roller plaster is an affordable way to give your walls a distinctive and personalized touch, whether you’re remodeling a single room or the entire house.

Painting

Painting the coating is necessary if the mixture was not painted prior to work (details on painting decorative plaster). Often used as a decorative plaster, roller plaster has a bark beetle effect. When painting with two contrasting colors, it appears especially beneficial. The grooves in this pattern can either be painted darker or lighter than the main background, creating a contrasting effect.

The paint and plaster should ideally come from the same manufacturer. If this doesn’t work, outdoor surfaces can be painted using acrylic-based paint or water-dispersion paint, which is impervious to precipitation. For interior painting, acrylic and water-based paints are utilized. Typically, facades are painted a single color.

Spray guns and other similar mechanization are typically used for painting projects with a large coverage area. Painters use brushes, rollers, and sponges to paint in two colors indoors. The painting technique is akin to applying a bark beetle effect to plaster. For the first layer when painting with a roller, use a long-nap roller. Paint is applied by rolling it both horizontally and vertically. The fact that every groove is painted is crucial. For the second layer, paint is applied in a single direction (vertically or horizontally) using a roller with a velor (short pile).

Decorative roller plaster is a simple, adaptable way to improve the appearance of your walls. It is a great option for people who want to give their spaces character without having to undertake major renovations because it blends the functionality of traditional plaster with the artistic flair of textured designs.

You can achieve a wide range of styles with the variety of rollers and plaster finishes available, regardless of your preference for a bold, dramatic effect or a subtle texture. This method of wall finishing’s simple application process makes it perfect for both novice and seasoned do-it-yourselfers.

In the end, decorative roller plaster offers an affordable means of adding personality to your house. It’s a technique that combines design and utility, making it simple to turn plain walls into distinctive accents that express your unique style.
