Finishing the arch with decorative stone – basic rules and requirements

A simple arch can become a visually arresting focal point in any space with the addition of decorative stone. You can improve an arch’s look and function as a design element by adding ornamental stone to it. Decorative stone adds texture and character that paint or wallpaper alone cannot, whether you’re going for a traditional or modern style.

For an arch to be successfully finished with decorative stone, there are a few important guidelines that must be followed. To guarantee that the stone adheres well, the surface must first be properly prepared. This entails clearing the arch and using a primer if required. Crucial steps include making sure the stone pieces are cut to fit the curve of the arch and selecting the appropriate type of adhesive.

Comprehending these fundamental prerequisites will aid you in attaining a polished outcome. Decorative stone can enhance the overall beauty of your space and beautifully highlight the arch with careful planning and attention to detail.

Preparation for laying decorative stone

Tools

Get the tool ready first. You’ll require:

  • Construction mixer
  • Building level
  • Cutting machine or cutting machine
  • Spatula
  • Bucket
  • Metal brush
  • Paint brushes
  • Rubber mallet
  • Trowel
  • Construction tape measure
  • Grouting syringe
  • Household sprayer
  • Wooden or plastic wedges of the same thickness

Consumables – making the right choice

Additionally, you’ll need consumables:

  • Glue for decorative stone

Our recommendation is to carefully read the packaging instructions before purchasing glue. Its properties ought to be correctly indicated in the instructions. There are several kinds of glue that can be used to adhere ornamental stone with varying weights. Consequently, buy glue after selecting a decorative stone that complements your style, not the other way around. In this instance, quality is paramount and price is secondary.

When finishing arches with decorative stone, it is assumed that you will also need to lay the vault in addition to the stone on a vertical surface. In this instance, there will be a constant force applied to tear the glued stone. It is therefore crucial to heed all advice when selecting the appropriate glue.

Important: a specific brand of glue must be used when installing decorative stone while the outside temperature is less than +5. Think about all of this when making a decision.

Additionally, you’ll need:

  • Grout of a suitable color
  • Primer
  • Water repellent

Our model is a concrete composition that is both water-repellent and water-resistant.

A tiny bit more. Many might wonder what the distinction is between waterproofing and hydrophobization.

The truth is that waterproofing keeps the walls from getting wet, but it also keeps them from breathing. The process of hydrophobization not only shields the walls from moisture but also permits airflow.

Finishing with decorative stone

Step one – surface preparation

The competent and accurate preparation of the surface is the first and most crucial step.

Prior to applying ornamental stone to the wall, the following preparations must be made:

  • Remove the remains of old whitewash, paint or wallpaper
  • The walls must be leveled with putty
  • Prime the wall and arch. The primer binds small particles of the wall and on such a surface any finish holds stronger

As a point of reference, primers are currently available for purchase for any surface. Taking into account the material of your walls, decide what is required.

Concrete walls, particularly those that are monolithic, require special adhesion primer known as "Betonokontakt."It is advised to moisten the back side of the ornamental stone with water when the temperature is high or the surrounding air is very humid.

Drywall arch – rules for finishing with stone

How to finish a drywall arch with ornamental stone will catch someone’s attention.

  • When laying decorative stone on drywall, it is recommended to use light grades of stone.
  • In addition, decorative stone can only be laid on gypsum board indoors.
  • If your drywall arch is under a canopy and outdoors, you cannot lay decorative stone on it.

Primer must be applied to the surface of moisture-resistant gypsum board, and the sheet must then be allowed to dry. After that, you are allowed to begin lying. Using a roller to apply primer is convenient. Remember to prime the arch’s inner and outer surfaces at the same time.

Proper preparation of stone tiles for laying

When laying decorative tiles, take your time.

  • Mix the stone from different packages.
  • Then lay the stone on the floor.
  • Select the position of individual stones so that its texture looks as advantageous as possible.

To make the stonework appear more natural, arrange it, for instance, in accordance with the differences in color shades or by arranging short and long pieces within the masonry.

Checking the stone – what is important to know

Make sure there isn’t a thin layer of foamy material, known as "cement milk," on the back of the tile before laying. If you locate it, you must use a metal brush to clean the back. Execute this.

As an example, cement milk considerably deteriorates adhesion. Your tile will just come to rest.

Applying glue – rules and recommendations

Dilute the glue in a bucket according to the directions on the package. Completely mix it with a mixer. The mixture needs to be consistent:

  • Using a spatula, apply a layer of glue to the wall where the tile is installed.
  • Also apply a layer of adhesive mass to the back of the stone with a spatula.
  • Each layer, whether on the wall or on the tile, should be 5-10 mm.

We advise against using an excessively thick layer of glue since this may cause the ornamental stone to come loose from the wall.

Crucial: there must be no gaps in the glue’s coverage of the tile’s back. This advice is applicable to the wall as well, to which the adhesive is also applied. An even layer needs to be applied to everything.

Condensation inside the masonry may result from internal voids.

We lay the stone ourselves – competently and efficiently

  • Apply the tile to the required place and press lightly.
  • Then, using a building level and a rubber mallet, align the stone.
  • Move it from side to side until it fits well against the wall.

Our recommendation: excellent masonry is needed to finish arches with ornamental stone. Consequently, use the handle of a screwdriver to tap the stone’s surface during installation. You can then ascertain whether there are any voids inside. In the event that they are located, the stone needs to be taken apart, the glue removed, and then reinstalled.

  • Additionally tap the surface of the stone with a mallet. If glue comes out at the edges, remove it with a spatula.

Simultaneously, if there is still glue on the ends of the stones, do not remove it. This will improve the adhesion of the stones to both the wall and each other. When finishing arches in an apartment with decorative stone (see Arch in an apartment: transformation into a decorative structure), excellent tile adhesion to one another is assumed.

Masonry with jointing

There are two ways to install man-made stone:

One of the interesting design options is to finish an arch with decorative stone that has jointing. If such a laying is required, wooden or plastic wedges must be used during the laying procedure. Choose wedges with the necessary thickness. The wedges can be taken out once the glue has dried, and then you can begin grouting the joints. When completing an arch or even just a wall with decorative stone, grouting the joints is an equally crucial step in the process. Such meticulous work must be carried out carefully and competently in order for the entire outcome to be satisfactory.

Grouting the seams

Using a syringe, fill the spaces between ornamental stones with a unique grout.

  • Fill the syringe with grout
  • Slowly squeeze it out and carefully fill all the seams
  • It is recommended to fill the seams with grout so that it goes deep into the outer edge of the stone by 3 – 4 mm. This way you will achieve a pronounced relief of the masonry.
  • If you need to get a smoothed texture of the masonry, you can fill the seam with grout at the same level as the front side of the stone.

  • After the solution begins to set, this is approximately after 30 minutes, it must be smoothed with a spatula or a special figured spatula for grouting.

For our reference, a conditional time range of 30 minutes has been indicated. Everything depends on the specific grout solution you purchased. For all work, make sure you read the instructions carefully and adhere to the manufacturer’s instructions.

A wide variety of grouts that mimic the color and texture of genuine mortar are available for purchase. Grout comes in a variety of colors and tones, so you can choose what suits your style and the needs of the intended design.

We cover the arch – "correct" chips

When finishing arches in an apartment with ornamental stone, one must assume that the stone must be cut to the appropriate dimensions.Many might wonder how to finish the walls with stone while still using ornamental stone to adorn an arch. It is important to realize that the smooth, cut edge of the stone where masonry meets a level, unlined wall will not always appear completely lovely and natural.

A result with different sized chips in the stone placed along the edges would be more acceptable. This will give the appearance of being more natural, and the outcome will be more natural.

Making decorative chips with sawing and cutting tools is a fairly simple process. You need to do the following in order to chip something correctly:

  • Using a knife, outline the main outlines of the future chip
  • All excess is bit off using pliers

We advise against attempting to eat directly after the mark. Starting at the edge, you must bite off a tiny portion. Everything superfluous is thus eliminated in accordance with the mark made. If not, the stone might fracture in an entirely unsuitable location.

  • Chip areas are corrected with a knife or file
  • Subsequently, to give the chips a smoother shape, they are processed with sandpaper
  • If desired or required by the design, the chips can be left unsmoothed. Everything is at your discretion
