How to frost glass at home. How to make frosted glass at home? Preparation of matting paste
Suppose you wanted to make something original out of simple glass. To do this, you can use one of many technologies. You can create a stained glass window, draw a picture on it, or make a mosaic. But the most interesting way to make truly designer products is to transform ordinary glass into frosted glass.
Once you frost it, the glass can be transformed into a material that changes its surface structure, causing it to become opaque. It is possible to use several processing techniques on one piece of glass in order to produce an original and truly individual product.
Anything made from glass - a decorative lighting fixture, a souvenir, a vase, various kinds of dishes - these items have always been in high demand among people. Quite often we choose an item from this list for a gift. Our attention can be attracted by a matte sconce, a salad bowl, glasses decorated with various designs, with patterns applied in the form of natural ornaments. Undecorated glass products are much cheaper, but practically do not attract attention. Not only a completely flat surface is subject to motivation, but also products of more complex shapes. There is practically no thing made of glass that cannot be decorated using the frosting method. And the appearance of this product will depend on the richness of your imagination.
One of the main purposes of frosted glass is protection from prying eyes. For example, you can organize a protected intimate environment in the bedroom, or install such glass in common areas to delimit individual compartments. Frosted glass is also used in the manufacture of partitions in sanitary facilities. If you are planning to place office furniture, then frosted glass partition walls will come in handy. Quite often, matting can be used in everyday life to make the glazed part of doors, edging mirrors, various utensils and lighting fixtures. Frosted glass can be purchased at a glass workshop, or you can make frosted glass from ordinary glass yourself.
The processing process can be carried out using several methods. This can be done mechanically, chemicals can be used, or sandblasting can be used.
In the technological process of mechanical processing, a special abrasive paste is used. This method is quite simple. It is not advisable to use the treatment chemical at home as it can be hazardous to health. If sandblasting is used, special equipment is required, and this method is used to transform mainly thick glass. Processing using this method can be quite rough. If frosted glass is installed in any of the packages, for example, window or door, then in this case it is tempered. But if you know how to frost glass at home, you can do it yourself. After all, this type of glass is very often used on kitchen cabinet doors.
Positive properties
The main positive properties of marked glass are:
- You can create a separate space invisible to prying eyes;
- A variety of design styles, elegant and beautiful frosted glass products;
- Variety of materials for processing;
- Various technologies for glass matting;
- Universal use of frosted glass.
But along with this, there are also some negative qualities of these materials. The main thing is a slight roughness on which dust can collect. To eliminate this flaw, you can use a special glass varnish.
Manufacturing technologies
The use of sandblasting to change the structure of the glass surface is the most common technology in creating a matte surface. Sand particles coming out of the device under high pressure remove the top smooth surface on ordinary glass, and it loses its transparency. If you change the fractional component of the abrasive material and the pressure in the sandblasting machine, you can change the roughness and degree of haze of the glass. There are actually several different types of glass sandblasting.
A method of etching the surface of glass, which creates an opaque surface, can be done using hydrofluoric acid. First, a stencil is applied to the glass, then a matting paste is applied to the stencil, which covers the unprotected part of the product. After a certain period of time, the fasting is removed, and the surface of the glass is washed off with water. The places where the paste was applied become matte.
If we compare matting with acid with a similar method using sandblasting, then after processing with paste the glass surface will be less rough and will not need a protective coating in the future. During production, the glass is completely covered with a matting substance, resulting in an ideal matte surface, which is called satinato.
Matte film for glass
Finishing glass with frosted film is the most economical way. The film is available with various patterns, designs and shading. But this method has some disadvantages. Glass covered with a matte film is not used in cases where there may be friction or strong moisture on the surface.
Lakomat
This is one of the special ways to give glass a matte surface. The glass is covered with a layer of a special matting varnish composition. It has several varieties, ranging from translucent to white. In order to mount glass this way you will need some tools. These can be rubber trimmers, various rollers and brushes.
Plasma treatment
An original product with unusual effects can be obtained by changing the glass surface using laser radiation. This is a method in which glass is processed using surface detonation. In this case, metal is sprayed onto the glass using plasma installations. This processing method involves heating glass to high temperatures using small drops of molten metal. After processing, the surface of the glass becomes covered with microchips and very small cracks. They are what create the matte surface. But this matting technology is used very rarely, since the equipment is expensive and the glass manufacturing process itself is very complex.
Matting paste
There is a way to frost glass using a special paste. But here you should adhere to certain rules, since making the paste itself involves working with a chemical substance. Therefore, it is necessary to purchase protective gloves, goggles and a gown. In fact, there are several recipes for making matting pastes. It is made on the basis of hydrofluoric acid or liquid glass. To prepare the paste using hydrofluoric acid you will need:
- Sodium fluoride;
- Gelatin;
- Some distilled water.
The components are diluted in a ratio of 2:1:25 and thoroughly mixed for a short time. The finished mixture is applied to the surface of the glass using a roller, and after treatment is washed off with running clean water. After this, the glass must be dried and kept in a 6 percent solution of hydrochloric acid for one minute. The matte surface in this case is achieved through the use of hydrofluoric acid. But this method is used only for completely matting the glass, since in this case a stencil cannot be used; the mixture may penetrate under the stencil.
Matting using liquid glass is achieved using the following method. A certain amount of liquid glass needs to be added to distilled water, then tooth powder is added and the composition is mixed well. Pigments can be added to this paste. Usually ultramarine or red lead is used. Well-washed glass is covered with the prepared paste using a roller, and after drying, it is washed with water.
Care of frosted glass
On frosted glass, any dirt can be seen more intensely than on regular glass, even fingerprints. Usually, stains can be removed immediately after they occur; simply take a damp microfiber cloth and wipe the stained areas. More serious stains, such as grease stains, can also be removed. The greasy area can be wiped with a piece of natural suede material and washed with slightly warm water with the addition of vinegar. After you have treated this area, dry the cleaned surface using microfiber. As an option for cleaning frosted glass, you can use a treatment made from powdered chalk and clean water. The mixture is applied to the glass with a sponge, and when it dries, it can be removed using regular newspaper.
Heavy contamination can be removed with ammonia, but it has an unpleasant and strong odor, so with this method of treatment you need to ventilate the room. Frosted glass that you make with your own hands can become a true work of art, and if you use modern care methods, this beauty will last for a long time.
And in conclusion, the simplest and most effective method of making frosted glass, which anyone can do. This does not require any special compounds, chemicals, sandblasting machines, films or all sorts of other methods. Take, for example, a small piece of ordinary window glass. We prepare a flat surface (preferably wooden) and fix the glass to make it convenient to work. For fixation, you can use small nails without heads. They should not protrude beyond the height of the glass. You will also need any flat metal object, such as a piece of angle iron and diamond lapping paste. This paste with the presence of diamond chips is used for grinding valves in cars; you can buy it at any store that sells auto parts.
Apply a small amount of paste to the glass and use a metal corner to begin rubbing it on the glass. The longer you take it apart, the more matte the glass will become. After finishing the treatment, you can wash off the paste using dishwashing detergent. That's it, after a few minutes you have real frosted glass.
Making frosted glass at home. In this article we will tell you how to make frosted glass at home. We will describe how to make stencils, and on what basis, which method is cheaper, as well as the pros and cons of each of them.
Afterwards we will tell you the main methods that will help make glass frosted.
Frosting of glass is rarely done, but most often this happens when:
If you are interested in how to make ordinary glass frosted with your own hands, you are unlikely to want to resort to expensive services. In our article you will find several proven methods that will help you do this inexpensively and with your own hands.
How to make frosted glass yourself?
Working with a stencil
Before you start doing anything, it’s worth considering popular glass frosting techniques, as well as methods for applying drawings and inscriptions. In the field of professional matting, engraving is occasionally used. This method requires additional tools and skills, and this is not suitable for everyone. At home, stencils will come to the rescue.
Choosing a stencil
There are three options here:
- Buy a reusable and suitable stencil (you will need aerosol glue for it).
- Buy a stencil for one-time use on self-adhesive film.
- Download the stencil on the Internet, transfer it to the desired scale, redraw it on film like an “oracle” and cut it out with scissors or a utility knife.
Glue and remove the stencil
If we talk about the first case, then you should apply glue to the stencil, wait a couple of minutes, and then stick it in the desired place and press the stencil to the glass with a dry, clean cloth using blotting movements. In the last two cases, we remove the backing from the film, glue the stencil onto the glass (which first had to be degreased and wiped dry), smooth it out with a rubber spatula, and if bubbles have formed, we pierce them and let out the air.
Advice: It is most convenient to transfer a stencil made of self-adhesive film to glass using a transparent mounting film: it will make it possible to stick the design without distortions or displacement. The film is removed before matting.
If the self-adhesive film stays on the glass for more than a day, it will be difficult to remove. For this reason, we advise you to remove the stencil from the glass as soon as possible after washing off the matting paste or drying the paint. We will talk about how to make a drawing with your own hands in other ways later.
We imitate dullness
How to make frosted glass at home in the easiest and safest way? We will talk about it further. I would like to note that this method will make it possible to obtain not a dull finish (in which the surface structure changes), but to create an opaque layer.
Pasting with film
This method will be a real salvation for those who want to frost glass cheaply and cheerfully. It is suitable only for flat products, or those that have a small rounding angle and will be used in dry rooms.
After you buy the film of the size you need at the hardware store, follow these instructions:
- Preparing glass - clean the surface with detergents and wipe dry.
- Try on the film, after which you need to cut it, if necessary, cut out decorative elements from it.
- Carefully remove the coating, moisten the film and surface with soapy water (this is easiest to do with a spray bottle).
- Apply the film to the glass, “drive out” excess moisture and air bubbles with a soft cloth or napkin.
Important: as when working with several decorative elements at the same time, it is better to remove (and stick) the protective layer one at a time. It is advisable to mark the external contours on the glass with a marker (after finishing work, it can be easily washed off with a cotton swab soaked in alcohol/acetone).
If you use this method, remember that matte surfaces do not have the same properties as glass - when exposed to abrasive substances and sharp objects, the film can easily tear. Such a defect cannot be corrected.
Matting with paint
Today you can find on sale waterproof acrylic paint for matting, which is produced in aerosol cans; it is also called aerosol frost (by analogy with the effect obtained). The method is quite convenient in that the opacity effect can be removed at any time using acetone, and a smooth surface will be available.
This paint is most often used not to make glass matte, but to apply matte designs on it. This is where the stencils we talked about earlier come in handy. Once they are applied, we recommend using masking tape to prevent accidental painting of other areas and surfaces. After preparation, spraying is done, and the manufacturer’s recommendations should be followed. Once the paint has dried (usually within 30 minutes), the stencil can be removed.
Chemical etching method - making glass frosted at home
It is not difficult to make glass using chemical etching, since the compositions will destroy the glossy surface. To do this, use special pastes or make your own compositions.
Note, that on the Internet there are several recipes for matting compositions that are based on hydrofluoric acid. They cannot be used at home due to the high level of toxicity: your skin, respiratory tract, mucous membranes and even teeth may be damaged!
Ready-made pastes
The assortment includes paint and varnish products for glass etching. They are convenient and easy to work with:
- First, prepare the glass: degrease and dry.
- If you are applying a drawing, paste the stencil according to the algorithm described above.
- Place the paste in small mounds using a rubber spatula next to the areas that need to be matted (don’t skimp).
- Quickly and confidently rub the composition onto the glass and leave for the time specified by the manufacturer (from 5 to 15 minutes).
- Remove the paste from the surface and put it back into the jar.
- Wash off the remaining composition with a foam sponge, remove the stencil, then perform an additional rinse and wipe dry.
Advice: Although matting pastes are certified and are not as dangerous as self-made compounds, you need to work with them wearing rubber gloves and in a well-ventilated room.
How to make glass frosted using liquid glass
You can make an indelible matting composition with your own hands; using simple silicate glue is enough. In chemistry and industry, such stationery is also called liquid glass. When it gets on regular glass, it breaks the integrity of the surface and creates a permanent matte layer.
In practice, you can make frosted glass with your own hands using silicate glue without effort:
- Lightly dilute liquid glass with water (preferably distilled).
- Add a little tooth powder or sifted chalk: you should have a mixture that will resemble liquid sour cream in consistency.
- If desired, you can add paints (water-soluble): ocher, red lead, ultramarine, mix all this so as to obtain a uniform color.
- Dip the roller into the mixture and roll it over a pallet or board so that there are no smudges, then paint the glass.
- When the glue dries, repeat the action.
The second layer is the final one, after which we wait for it to dry, wash the glass and can be put into operation.
Important: When using this method, matte designs cannot be applied using stencils, since during polymerization the glue will seal the edges of the stencil to the glass.
Frosted glass by mechanical means
Despite the fact that glass is a durable material, under certain conditions it can be scratched, in which case it loses its glossy properties. This means that matte finish can also be achieved mechanically!
Matting with sandblasting material
The essence of the method is that sand falls onto the glass surface under high air pressure, which creates microscopic depressions. This technology can hardly be called “homemade”, since to perform it you will need at least a sandblasting tool. With some skills, you can make such a device with your own hands, but to frost a couple of glasses, you shouldn’t bother so much.
Note, that this method can only be used in isolated rooms and on glass with a thickness of at least 0.5 cm.
Matte with diamond paste
The problem of how to make frosted glass at home can be solved using an abrasive lapping paste. Since the method is labor-intensive, it is not suitable for large surfaces, but it is appropriate for applying a design or matting small areas.
The steps are simple: apply a fine-grain paste to a glass surface or stencil and, using a piece of glass, rub it in a circular motion. Despite the fact that the method itself is not expensive, there is also a drawback: it takes a long time to rub, and it is also difficult to achieve uniformity.
Start small. All the technologies that we described above make it possible to implement many ideas. But before you start doing anything, evaluate your strength. Don’t take on large volumes right away: it’s better to practice on small glass items.
Abstracts before starting work - briefly about glass frosting
So, can all glass be frosted? Almost everything, including painted and transparent cabinet glass, mirrors, furniture inserts, dishes, car glass, and crystal. The only thing that cannot be frosted is heat-resistant glass, which is indicated by a special sign.
Aerosol and paste for frosting glass do not contain aggressive acids, but you must work with these chemical compounds in a ventilated area, wearing gloves and a respirator. The temperature of the room where the glass will be frosted should be from 18 to 30 degrees. The matting paste is also stored under the same temperature conditions. At lower rates, the composition begins to crystallize. If this happens, dip the tube of paste into heated water; this will not affect its quality in any way.
Before you start, purchase: matting paste, alcohol, rubber gloves, a plastic or rubber spatula, a stencil for creating a design, aerosol glue, sponges and napkins. We prepare the work surface - degrease the glass with alcohol and wipe it with a microfiber cloth. If you are applying a design to glass, prepare a stencil in advance. You can purchase it in a store or make your own pattern using film as a base. Oracal. To prevent the stencil from moving while working, treat it on the reverse side with aerosol glue. It will fix the film well and will not leave marks; use masking tape if necessary. To be safe, place parchment paper on top of the stencil and smooth everything out again.
Now let's move on to the matting itself. Apply the paste in a thick layer to the stencil and distribute it evenly over the entire surface, leaving it to soak in for 10–15 minutes. After this time, the glass will be etched and a design will be imprinted on it. We remove the top layer of paste and place it back into the container, and wash off any small residues with water, remove the stencil and wipe everything dry with microfiber. If you don't want to buy matting paste from the store, you can make your own. For the first option, take liquid glass and mix it with a small amount of distilled water and a pinch of tooth powder. To create a colorful design, add a dye such as red lead or ultramarine.
For the second option, prepare 2 parts sodium or potassium fluoride, 1 part gelatin and mix them with 25 parts distilled water. Apply the resulting mass to the glass, and after it dries, pour 6% hydrochloric acid on top and leave it for a chemical reaction for a minute. We work with gloves and with the window open. As a result of this interaction, hydrofluoric acid is formed, which will etch the glass. At the end, as with using store-bought paste, thoroughly rinse the glass with water.
Aerosol and sandblasting method - creating curly patterns
To apply matte patterns on small surfaces, such as a glass goblet, candlestick, flower vase, barn glass, you can use dry aerosols. They are sold in a wide range of different colors, giving you the opportunity to create a colorful matte design in a festive style. To process glass with your own hands using a matting aerosol, you will need an already familiar set of tools.
First, we degrease the surface with alcohol, after which we apply a stencil, and seal all areas of the glass that you want to protect from paint with masking tape. Before starting work, shake the can and distribute it over the surface of the drawing. To ensure that the paint applies evenly, apply 2-3 matting layers, waiting for each of them to dry completely.. If this does not seem enough to you, then to consolidate the effect obtained, you can apply a matte aerosol varnish on top of the design. Its complete drying time is 1–2 hours.
A sandblasting machine is used to impart a haze to glass in production. Now you can find similar devices for household use. Compared to matting pastes and aerosols, they have wider capabilities. Using sandblasting machines, you can create matting of varying depths and densities, and also use it to work with large surfaces. However, it will require some skill. But if you're willing to take the risk, then let's get started.
Among the disadvantages of this method, I would like to note the reduction in glass thickness to 3 mm after processing. Therefore, glass with a thickness of at least 5 mm is suitable for working with a sandblasting machine.
We are talking about a technology that allows you to decorate any glass surface without much expense: from glasses to window glass and mirrors.
Using proven and uncomplicated technology, you can create a stylish interior environment that will surprise you with its unusualness and reward you with a good mood for the work done.
Glass matting is a technology whose effect is exactly the opposite of polishing. If polishing gives the glass shine and transparency, then matting, on the contrary, makes the surface rough, opaque and matte. Why does the glass surface need such a transformation? It's simple: matte patterns allow you to add originality and special charm to even faceless objects.
Frosting of glass can be done in various ways: chemical and mechanical, by firing and using paint and varnish matting coatings. But if for an industrial scale all of the listed methods are equally suitable, then at home it is more advisable to practice chemical matting and applying matte paintwork materials. They are the ones that give the highest quality results, and we will talk about them.
Chemical matting
Chemical matting is performed using a special matting paste. It allows you to change the internal structure of the glass surface by exposing it to aggressive chemical compounds and destroying the silicon oxide crystal lattice. Upon completion of the process, silky translucent images are formed on the glass, which are so resistant to external influences that they cannot be removed even by mechanical means.
Using film stencils, you can get matte designs of any size and configuration: these can be inscriptions, patterns, logos and entire compositions made up of several stencils.
For chemical matting we will need:
- degreasing liquid (medicinal alcohol);
- disposable rubber gloves;
- napkins;
- rubber spatula;
- aerosol glue for gluing the stencil (if you use a stencil made of self-adhesive film, no glue is needed);
- matting paste;
- a reusable stencil with a design and, of course, the glass object that you are going to decorate.
Alcohol will be needed to make the glass surface perfectly clean. This will ensure the picture is clear and evenly matte. Other types of solvents can leave a film of persistent chemical compounds on the surface of the glass, so it is better not to use them.
If the matting paste is applied to an unprepared and non-greased surface, then the finished drawing may become stained, and such a defect cannot be eliminated by any means.
Disposable gloves will help keep the glass surface perfectly clean and protect your hands from exposure to aggressive chemical environments (despite the fact that the composition of the matting paste is considered harmless to human hands, it is better to play it safe and protect them).
As for the glue for sticking the stencil: it is better to buy special aerosols that do not leave marks on the surface of the glass. They can be purchased in stores or ordered online.
The most important component involved in the technological process is the matting paste. There are recipes for making your own matting composition, but experienced people recommend using a ready-made ingredient, which can be purchased at a specialty store.

The certified paste from the manufacturer reacts perfectly with glass surfaces, is safe for human health, does not contain strong acids, and its use can achieve excellent results.
As for stencils, they are made on the basis of a rigid film, which makes it possible to obtain products for reusable use. In some cases, stencils have a self-adhesive backing. There are three ways to prepare a stencil with the required image:
- Cut it out yourself using a sharp and thin knife.
- By purchasing a ready-made product in a store.
- By ordering the production of a stencil on a special plotter. This method is the most preferable, because the plotter can produce stencils with designs of any complexity.

We think about what to draw, look for a picture and prepare it for the cutting plotter. Optimists can buy a special knife for stencils and cut by hand, but using a plotter is faster.
Sequence of work
Having prepared everything you need and selected a glass object to apply the image, you can get to work. First of all, you need to measure the stencil and mark its future location (for example, using masking tape or a washable felt-tip pen). After all, when glue is applied to the film, it will be much more difficult to proportionally place the design on the glass.
Having marked the surface, it should be wiped dry and treated with alcohol.
After degreasing, fingerprints must not be left on the glass surface. This will result in defects appearing on the decorated surface or distortion of the matte design.
At the next stage, the stencil is placed face down on a clean sheet of paper and covered with glue. If the stencil has a self-adhesive base, then this procedure should not be performed.
The glue is applied in a thin layer - in accordance with the instructions. Then the stencil is placed on a pre-marked area of the glass surface, covered with a clean sheet of paper and carefully smoothed with a napkin or rag. The paper will help maintain the integrity of the stencil and ensure its reusability.
The key point of the presented sequence is the application of matting paste to the stencil.
Once on the glass surface, the matting paste instantly enters into a chemical reaction with it. Therefore, it is important to protect from small drops those areas of the glass that are not covered with a stencil.
The paste is applied to the drawing in a continuous and even layer. The thickness of the layer is not particularly important, but, as a rule, it is 4...5 mm.
The duration of matting should correspond to the recommendations of the matting paste manufacturer (usually the process lasts 15 minutes). After waiting the recommended time, you can begin removing the stencil. The action is carried out in several stages:
- We collect excess paste from the surface of the stencil back into the container. Considering that the paste is reusable, you will still need them.
- Wipe off the remaining paste with a dry cloth.
- Without removing the stencil, wash off the remaining matting composition with plenty of water. The most effective way to wash off any remaining paste is with a stream of running water, but in extreme cases, a filled five-liter bottle will do.
That's all. You can remove the stencil. After completing the above steps, the image will be permanently imprinted on the surface of the glass.
Matting with spray paint
Aerosol paint for matting (also called “aerosol frost”) allows you to create dense and opaque images on glass that will delight you with their beauty for a long time. And if such a need arises, then the boring picture can be washed off with ordinary paint remover.
The preparatory operations before applying aerosol frost are similar to those performed before applying the matting paste: trying on the stencil, degreasing the glass, gluing and smoothing the stencil.
Before applying the aerosol, the glass surface not to be frosted must be completely covered with paper or masking tape. It also wouldn’t hurt to cover the space around the glass with improvised materials. This caution is due to the fact that the spray radius of aerosol paint may extend beyond the stencil.
The paint should be applied in accordance with the manufacturer's instructions. After the paintwork has dried, the stencil can be easily removed, and the result of the work done will be revealed to your eyes.
This matting method is somewhat simpler than the previous one. At the same time, it has its own advantages. So, an unsuccessful coating can always be washed off and a new design applied.
Having familiarized yourself with two matting methods at once, you can choose the most suitable one for yourself. In the meantime, let's take a look at samples of decorative items made by members of our portal using matting paste.
Frosting glass by hands of FORUMHOUSE users
Glasses, intricate chandeliers and memorable souvenirs - all this can be made using ordinary glass bottles, stencils and matting paste.
As you can see, having a good imagination, you can realize the most unexpected ideas. In the case of a bottle, the main difficulty is to evenly divide the glass container into two parts.
An ordinary glass cutter and a special device that you can easily make with your own hands will help you with this.
Frosting of glass is carried out to decorate the surface, obtain a thematic pattern, reduce its transparency, or to mask minor scratches and chips. This process can be carried out both on glass interior doors, cabinet doors, and on glasses for wine and champagne. There are several methods for frosting glass. Let's consider the most affordable and easiest method at home.
You will need:
- matting paste;
- the glass itself;
- rubber spatula;
- Oracal film or ready-made stencil;
- latex gloves;
- alcohol.
