So, what threatens the laying of ceramic tiles on the paint? This type of coating is rare today, since the tile bypasses paintworks in terms of frequency of use and its properties. If you decide to replace a similar finish on the tile, you must first understand the type of old coating and find out the possible options for further work.
On the question, can we put the tile on the oil, nitro or water-level paint in the bathroom or other room, give a clear answer is quite difficult. The fact is that, in principle, prepare the wall with one of these coatings to the facing possible, but the quality of masonry may suffer if there are even the slightest deviations from the technology.
Of course, you will need extra time for surface preparation, but if you begin to glue the tile on top of glossy paint, the following problems may occur:
- The solution slips back at the stacking stage;
- In the future, the masonry will turn with the slightest load on it;
- In the process of installation it will be difficult to keep the tile in the right place, it will move under its own weight;
- Already in the first year of operation, it may be necessary to repaid.
In order to prevent the above-mentioned nightmares of repair, it is important to properly prepare the surface.
The list of necessary measures may differ depending on the type of paintwork.
When preparing the surface for subsequent tile cladding, be sure to remove the enamel
Enamel
The most problematic, perhaps, is the coating of the walls and the floor enamel. This surface is characterized by glossy glitter, ideal smoothness and slippery. In addition, she does not miss moisture and has weak adhesive indicators.
If you plan to put on top of the enamel of the tile, the result will turn out extremely unreliable and unpredictable. That is why it is recommended to clean the wall from the paint under the laying of the tile in advance. For this purpose, you can use different approaches and tools:
- Bulgarian. It will take a grinding nozzle to work, with which you need to process the most accessible area. The paint layer will take off with particles of concrete or plaster. Because of the large amount of dust, it is necessary to have working overalls and personal protective equipment.
- Ax. With the help of the ax, you can only enamel with plaster. Minus such a method - as a result, it turns out a rather uneven surface.
- Sandpaper. According to the principle of the grinder, you can use the sandpaper, but the efforts will take it at times more. This method is only suitable for small areas.

Ways to remove enamel from walls with various tools
As a result, you should remain a naked concrete wall. Small unprocessed areas are not carried by a special threat, but still it is better to try to get rid of them or at least to clean up to giving roughness.
Oil paint
Another popular composition is oil paint. Unlike enamel on such a surface, it is quite possible to put the tile if you perform a number of preparatory work. In this case, it is important to make the maximum roughness of the coating and increase its adhesion.
To put the tile on the oil paint in the bathroom, you must perform the following manipulations:
- Clean the wall with a sandpaper or a grinder to create a rough surface.
- Make shameless notches across the area. To do this, you can take an old ax with a non-footing blade, a chisel or chisel. The more notes, the better.
- Clear from dust and degrease the wall, such as acetone or alcohol.
- Thoroughly wrap the surface of the primer deep penetration with the brush so that the liquid filled each notch and the time.
Technology of surface preparation under tile with oil paint
Thanks to this method, it is possible to significantly improve the surface adhesion and increase the reliability of future masonry.
Water-emulsion formulations
Another actual question: Is it possible to glue the tile on the water-emulsion paint? This type of coating has cardinal differences from the previous ones. It should be noted that in the bathroom and other premises with high humidity, compositions with latex additives are predominantly used. Such paint has fewer water permeability.
There is one feature in the water-making paint: when connecting air access and enhance humidity, it can declare and start peeling. That is why it is extremely recommended to put tiles on it. Even if you treat it with high-quality primer, over time, the base of the facing can start bubble.

The easiest thing is removed by the water-emulsion paint
Remove the water-free paint is easier than other types of paints. Here the method of stripping the walls together with the plaster is perfect, as it is preferably painted in advance spliced surface. To work, depending on the area of the room, will leave 1-2 days.
Selection of glue
In the question of how to put a tile on the paint, there is another important point - what is better to glue the tile. In this case, it will be necessary not a conventional cement-sandy solution, but a special reinforced glue.To increase its chain and the degree of penetration into the base surface, it is possible to add pva glue.
There are special compounds that already contain similar additives. Fast-drying adhesives are also recommended to prevent raw masonry risk.
If you follow all these recommendations and not be lazy to prepare the walls to cladding, the new tile will serve you no less than the one that is put on the concrete surface.
