Assessment of the degree of destruction

Before repairing the floor covering, it is required to conduct an audit and assess the degree of its destruction. If during the inspection it is revealed that the damage has affected more than 30% of the surface, it is justified to carry out a major overhaul of the floor. The old flooring is dismantled, the new lining is laid out.

If the canvas is partially damaged, minor repairs are carried out. Well if the owner will leave a certain number of tiles after the lining is completed, - this material is most suitable for the implementation of such work. Otherwise, you will have to look for ceramics that are suitable in tone and size in the store.

The main difficulty of restoration work is that it is difficult to remove the tile without hitting the rest, whole parts.

There are several ways to remove damaged material when repairing tiles on the floor:

  • seams are cut with a drill with a thin drill;
  • the seams are sawn with a grinder;
  • the tile is dismantled manually with a chisel or perforator.

When the tile is removed, the adhesive layer is removed with a sharp scraper. If damage to the screed is visible, they begin to restore it, for which they use a cement-sand mortar. If the base is not damaged, use only tile adhesive.

Stages of work

Do-it-yourself floor repair is carried out in stages. The recommendations presented can be used as a guide to action when removing a single destroyed element or small groups.

Removing damaged tiles

If the damaged tile is against the wall, the skirting boards for the tiled floor are carefully removed. After repair, they can be installed back. On the back of each skirting board, marks are made with a pencil. This will avoid confusion when reinstalling.

General sequence of actions:

  • along the diagonal of the damaged tile, holes are made in increments of 2 cm. It is convenient to work with a drill or a puncher;
  • with the help of a chisel and a hammer, it is broken into small pieces;
  • removal of fragments should be directed from the center to the edges.

cleaning

The resulting dust and debris is removed with a vacuum cleaner. It must be understood that careless cleaning of the surface will impair adhesion and repair floors in the house will be ineffective.

Foundation preparation

A self-leveling mixture, cement-sand mortar or tile adhesive is poured onto the subbase. The screed must dry.

Laying

Using a notched trowel, the tile adhesive is applied to the surface. The tile is laid on the solution, controlling the horizontal. If necessary, the position of the tile is adjusted with a mallet.

Grouting

When the adhesive mass has dried, proceed to the grouting. The composition is applied with a rubber spatula. Excess is removed with a damp sponge.

Repair of shallow cracks

Working with a puncher, drill, tile cutter is associated with injury. It is recommended to use personal protection or seek professional help

To eliminate the defect, you can use a cement mortar. They fill the crack and carry out high-quality grouting. Within 72 hours, the surface is regularly moistened, which is required for a better setting. The treatment area should be covered with a film.

If an adhesive is used, the sequence of actions is as follows:

  • with the help of a damp rag, dirt is removed from the crack;
  • tile adhesive is kneaded with a proportion of pigment corresponding to the shade of the surface;
  • the defect is carefully filled with the composition;
  • the area is covered with wet sawdust and left for 24 hours.

Restoration of damaged areas

A special stencil will allow you to update the coating. The pattern is applied to the tile in accordance with one's own preferences. Before restoration, the floor is washed with a weak solution of detergent and brought to a dry state. When the pattern is on the tile, it is fixed with abrasion-resistant varnish, observing the drying time of the paint.

If the tile is intact, but lagged behind the floor

The module can be glued again. The area where the tile is placed is pre-expanded and deepened. It is enough to work out 10-12 mm. Residues of glue, dust are removed with a vacuum cleaner. The surface is primed and filled with concrete mortar.

The tile is cleaned from the back side and immersed in the solution while maintaining the evenness of the seams. Excess composition is removed with a damp cloth. Within 7 days, the restored area is kept moist.

Seam update

If poor-quality grout was used during the main repair, during operation it will collapse and gaps will form on the tiled floor. In rooms with an unstable level of humidity, black mold appears between the seams. To eliminate the defect, you can remove local areas or completely remove the grout.

Full replacement is advisable for a large area of ​​​​damage. Spot repair of ceramic tiles will look unaesthetic and form many zones that are different in color.

Sequencing:

  • old grout is removed with a sharp wooden object;
  • a new layer is laid in its place with a rubber spatula.

The return of brilliance

To ensure that the floor covering does not require repair, it should be professionally installed based on the operational features of the room.

If the surface of the tile has lost its luster, color saturation, it can be updated with painting. The area is sanded with sandpaper, degreased with acetone and primed. The selected paint is applied using a roller.

Use of cold welding for ceramics

Damaged pieces of floor tiles can be repaired with adhesive composition, which is called cold welding. It is permissible to work with the material on oily and wet surfaces. The product is produced in the form of a plasticine rod and contains amine, epoxy resins, mineral fillers.

Damage repair is carried out as follows:

  • before repairing a chip or other defect, the repair site is cleaned of dirt, cleaned with sandpaper, degreased with acetone;
  • the surface must dry;
  • the necessary part of the rod is cut off and kneaded with fingers;
  • the composition is viable for 5-7 minutes. When heated, the time decreases, when cooled, it increases;
  • the mashed composition is applied to the working surface and fixed for 15 minutes;
  • after 1.5 hours the surface is rubbed and can be used.

Kitchen

If the purchase of tiles is required, they choose the most suitable design, the third class of wear resistance, water resistance - at least 3%, friction coefficient - no more than 0.75. According to technical indicators, the tile should correspond to average parameters. Repair of the floor in the kitchen is carried out in a standard way.

Grouts, adhesives and other solutions must have moisture resistant properties.

Bathroom

For repairs, tiles of the first class of strength are used, resistant to chemical and moisture effects. It is recommended to use furan or cement grouts, but their use requires a professional approach.

Living room

Repair of tiles on the floor is based on design features coatings - it is necessary to choose the appropriate material in color and design. The wear resistance class can be first or second. There are no requirements for humidity and chemical exposure.

The corridor

The corridor is the place where the impact of abrasive particles is high. For restoration, tiles of the fourth class of wear resistance are used. Resistance to chemical and humidity effects is welcome. The grout must be strong, which is typical for furan and epoxy compounds.

Bedroom, children's

In such rooms, the need for repair of floor tiles rarely arises. There is an insignificant level of loads, which allows the use of tiles of the lowest class. The material must be environmentally friendly. If the work is carried out on a coating laid on a “warm floor”, a professional approach is required.

Elimination of minor damages such as scratches, cracks, abrasions on a single floor tile can be carried out independently. The remaining defects must be repaired by an experienced craftsman, otherwise the floor will become unusable again.

  • do not allow glue to get on the front surface of the tile. If this happens, the composition is immediately removed with a moistened clean rag;
  • Do not use abrasive cleaners for cleaning. This will lead to scratches;
  • before entering the room where the lining is laid, it is better to put a mat for cleaning shoes;
  • polished tiles cannot be used in eating areas and places with high humidity, due to increased slip.

after installation of ceramic tiles, the surface should be treated with special agents that protect micropores. This will prevent the penetration of oils, dyes, fats deep into the coating.

Tile repair half shown in the video:

Ceramic tile is an almost indispensable material that is used in almost every construction or renovation. This is due to the indispensability of tiles in some cases, when no other material would be appropriate. Tile chip installation and repair services are in high demand due to the fact that tiles come in a variety of varieties designed for different purposes. Here you can note such types of it as:

  • floor tiles with high level wear resistance and minimum degree of abrasion
  • kitchen tiles for small walls 100x100 or 150x150
  • large tile blocks for the floor 600x600 or 1000x1000
  • refractory brick tiles for fireplace cladding

These are just a few examples different types ceramic tiles. Each of them has its own characteristics when laying and repairing. Only a specialist who knows them will be able to carry out such work with high quality. The services of such masters are offered on the Youdo crowdsource exchange, which spreads its activities in Moscow, St. Petersburg and other cities of these two regions.

Chips on tiles. Origin

Repair of chips on the tile will be carried out correctly if the nature of their occurrence is accurately determined. The fact is that chips can occur in the following situations:

  • impact with a heavy load or impact with a heavy object
  • the occurrence of voids under the tile, causing it to fail and the appearance of cracks or chips
  • shrinkage of the building, due to which the deformation of the walls occurs
  • poor quality laying work, which can cause the adhesive to break, causing the tiles to move

Repairing chipped tiles

Based on the nature of origin, a method is chosen for repairing chips on the tile. Depending on it, repair work may be as follows:

  • with small chips caused by impacts, you can carefully glue the broken fragment, hiding the seam if possible
  • in case of failures, it is necessary to completely remove the damaged tile, and maybe several adjacent ones, after which, eliminate the voids that have appeared
  • the most difficult option is the shrinkage of the building, since in this case, most often it is necessary to completely shift the tiles

Sometimes it becomes necessary to change the design of the old ceramic tiles in the bathroom without major repairs. It happens that the pattern on the tile has faded due to limescale, and defects in the form of small potholes or cracks have appeared on individual elements of the coating. They resort to decorating the cladding, and when it is necessary to change the style of the interior. You can update the tiles in the bathroom without changing it yourself in several ways.

Damaged cladding is corrected by partial replacement of tiles. A contrasting tile or decor is glued to the vacated space.

Dismantling begins with the opening of the seams. For this tile, something sharp is circled along the contour. Then the ceramic tile is pry with a chisel. After that, they clean the wall from the old mortar and glue it necessary element. Don't apply too much glue. Tiles should not rise above the rest of the cladding.

You can upgrade your bathroom simple method- using vinyl stickers. This method is less labor intensive. Stickers are recommended to be glued to the walls, because there they will not be subjected to mechanical stress.

The tile is also decorated with contour paints. The easiest option is to apply a dot painting or depict geometric figures. The walls in the bathroom are also completely repainted.

Vinyl tile stickers

Decorating tiles with stickers does not take much time. Damaged tiles are not reconstructed before. Vinyl stickers will hide chips and cracks.

For bathroom decor, you should use stickers that are resistant to moisture, steam and cleaning products. It is not necessary to glue the entire lining with them. You can update the old tiles in the bathroom with the help of stickers by arranging them in a checkerboard pattern. To do this, choose stickers of the same size as the tile.


Another option for updating decal cladding is to create decorative panels. They are placed above the sink or in the central part of the wall. You can buy a ready-made panel or assemble it from individual small stickers yourself. The second option is more preferable when creating large compositions.

On sale there is a self-adhesive film for the bathroom in rolls. It is a little more difficult to work with than small stickers, as bubbles and folds can occur during decoration. Therefore, the film must be well stretched when gluing. If bubbles still form, they can be pierced with a needle.

Application of patterns

The pattern on the tile should be chosen taking into account the design of the room. For a bathroom in a modern style, geometric patterns are suitable. They are easily applied using stencils that are glued to the tile. In this case, you should use spray paint. It is convenient to spray on a stencil.

Work with tiles is reduced to the following principle:

  1. Fixing defects.
  2. Foundation preparation.
  3. Painting.
  4. Applying a protective compound.

Before decorating on a tile, all chips and cracks must be repaired. It is best to use putty for wet rooms. Tile restoration is obligatory step, since the paint will emphasize the existing defects.

Potholes and cracks in the old tile are repaired with a small trowel. The dried putty is rubbed to make the surface of the tile more uniform.


Before applying the drawings, the tile must be thoroughly washed. After drying, it is degreased with acetone. If paint on ceramics will be used to draw patterns, then the tile should not be treated with fine-grained sandpaper and a special primer. Such decorative compositions fit perfectly on smooth bases. When using all other types of paints, it is worth increasing the adhesion of the tile.

For drawing a picture, you can also use improvised means, such as masking tape. With its help, a pattern of triangles is applied. This modern solution is suitable for square tiles. The location of the triangles must be thought out in advance. The easiest way is to sketch on paper.

To apply the pattern, you need to divide the tile in half diagonally. A thin adhesive tape is glued around the desired triangle. Then the figure is carefully painted over with a small brush.


Instead of patterns, you can resort to continuous painting of tiles. This is the most versatile cladding decor option, because a plain tile will fit into any style.

Solid painting without removing

With continuous staining, the entire surface of the cladding is processed, including tile joints. Work is carried out with a roller and brushes. The paint is applied in a thin layer. Particular attention is paid to the seams. They are carefully painted over with a brush.


Updating the tiles in the bathroom with the help of solid coloring is not possible everywhere. It is better not to touch areas of the cladding that are often exposed to steam. After some time, the paint in these places begins to peel off and move away from the tile.

Tiles are painted near the washbasin, toilet bowl and on the floor. The walls around the bathroom, if desired, are finished with steam-resistant panels. They are mounted on top of the old tiles. Before finishing, the walls are cleaned and degreased. Then they are dotted with special glue or liquid nails. The panels should be pressed firmly against the wall so that they adhere well to the tile.


With the help of continuous painting, space is zoned. For example, you can make a contrasting shade in the shower wall. Another option is the distribution of color accents. The space in this case should be evident immediately upon entering the bathroom. In a different color, you can paint the wall near the washbasin.

Basic Rules

All cladding must be cleaned of dirt before work, otherwise the paint will lie unevenly on the surface of the tile. We recommend the use of abrasive cleaners to remove dirt.

The tile must be treated with fine-grained sandpaper and adhesive primer. This will increase the adhesion of the paint to the smooth tiles in the bathroom. Particular attention during processing should be given to tile seams.

It is worth using paint designed for ceramics or faience. Latex and alkyd formulations have proven themselves well. It is necessary to paint a small area of ​​the cladding, located in an inconspicuous place, and then check the durability of the coating.


Painting should be started only a day after applying the primer. During this time, the product will definitely dry and form a strong film.

The paint is applied in several layers. This will result in a more even and durable coating. The previous coat of paint must dry completely.

Required Tools

To update the tile, you will need the following tools:

  • Sandpaper.
  • Sponge.
  • Masking tape.
  • Cover film.
  • Roller with a small pile.
  • Brushes.

Do-it-yourself voluminous decor

They help to update the tiles in the bathroom and improvised means like beads, small shells and pebbles. decorative elements stick on tiles. They must be small so as not to fall off. It is better to place voluminous decor in places that are slightly dirty, because textured elements are harder to wash.

Seam update

It is not necessary to update the old tile. You can give the cladding a fresher look by cleaning the grout. Over time, the seams darken, change color and become dirty. This is due to high humidity in the bathroom. To cope with the darkening of light grout, you can use various means. To restore color, it is recommended to use special pencils or markers. You can also restore the grout with paint. For cement mixtures, Fuga Fresca from Mapei is suitable. The advantage of this paint is an extensive range of colors.


Special tools do not always help to cope with the darkening of the seams and dirt on them. It is especially difficult to restore light shades. In addition, paint is not advised to be applied to cracked seams. The only way out in this case is to replace the grout.

Rules for cleaning damaged areas

  1. The damaged area is removed with any sharp object.
  2. For better cleaning of the seams use a vacuum cleaner.
  3. In case of minor damage, the grout is replaced locally.

Complete replacement

Completely remove the grout mechanically. To do this, you can use a special scraper-extender. They need to work carefully so as not to damage the tile. Old cement-based grout should be pre-treated with an acid cleaner. This will help speed up the replacement.


You can quickly and easily update the interior with the help of tile restoration. Tiled flooring sometimes needs repair. Even considering that high-quality tile material is very dense, any careless handling can damage it, break it or deprive it of its former attractiveness. In this case, the restoration of ceramic tiles will help out, which is so popular now due to the fact that it is often difficult to find a replacement for a damaged tile composition.
