1. Should I only look at the color while buying paint?


As much as the color of paint, you should also look at the paint's capacity to protect the surface for a long time and properties such as maximum wipe-ability, the prevention or delay of mold and fungi.

2. Are the cheap paints really economical?

The amount of paint that will be used is based on the area covered by the paint. In other words, the paint’s ability to cover a larger area and have good coverage ability are important factors that need to be considered. Cheap paint usually has less coverage area per liter.

3. After how many years should interiors be repainted?

A high quality and wipe-able paint applied on a well-prepared surface by good workmanship preserves its color and brightness for 5 to 6 years.

4. What factors I should consider when selecting a color?

The amount of light received by the surface to be painted should be considered. Note that colors may be perceived differently under natural light and electrical lighting. The harmony of the selected color with furniture and drapery is also important.

5. How can I select the correct roller for the paint selected?

The paint and surface types (ceiling, interior or exterior) all affect the choice of roller. Short-pile satin rollers should be used for water- or solvent-based satin paints on interior walls. If plastic paints are applied use a plastic paint roller. On exteriors, coral or lambskin rollers can be used depending on the type of paint.

6. How should I prepare surfaces before painting?

For the best results, preliminary surface preparation is essential. Old paint should be sanded, and dust should be cleaned off the surface. Cracks or holes should be filled with an appropriate paste or filler. The topcoat should be applied after a primer is applied to the entire surface.

7. Can water-based satin paint be applied on old solvent-based satin paint?

First of all, the painted surface should always be sanded to provide a key. After dust is cleaned off, Transfer Primer should be applied. Only after that, the surface is ready for water-based satin paint application.

8. I have left over paint, how can I preserve it?

To be able to use the left over paint again, an amount of thinner enough to cover the surface of the paint should be added and the paint should be stored at a temperature of 5 to 25°C.

9. How and what kind of paint should I apply to mold and bacteria growing surfaces?

Paint should not be directly applied to mold growing surfaces. First, surfaces should be cleaned with a bleach and water solution (1 part bleach to 3 parts water). Apply the primer and paint only after the surface is dry.  Choose an antibacterial paint that delays the formation of mold. Elegans Anti-Aging or Elegans Extra can be applied to such surfaces.

10. Even though I paint my walls facing north every year, I can’t solve my mold growth problem. What should I do?

Since there may be problems in your building regarding thermal insulation, the first and proper solution would be external sheathing. If your building’s residents cannot reach a common decision, the problem wall can be sheathed internally.

11. What is the best weather condition for external paint application?

The temperatures between +5 and +30°C are ideal. Before and after application, the surfaces should be protected from rain. Avoid applying the paint on windy days.

12. Can I paint my interior walls any season I want?

Yes, you can. Only the ambient indoor temperature affects drying time.

13. In what ratio I should thin the paints?

Follow the thinning ratios given on the packaging. Thinning more or less may affect the paint’s performance, such as coverage and surface protection. 

14. How can I calculate the amount of paint required for interior application?

For example, if you are living in a house with a living space of 100 m², the ceiling area is calculated as 100 x 0.85 = 85 m² and the wall area is calculated as 100 x 2.2 = 220 m². Based on these figures, you can determine the amount of paint you will need by looking at the consumption values per square meter given on the label of the paint you selected.
In paint consumption, the condition of the surface and the number of coats will affect the amount of paint that will be needed.

15. How can I calculate the amount of paint required for exterior application?

The approximate paint area is calculated as the building perimeter x number of floors x height of floors x space.
For example: 100m x 8 x 3m x 0.8 = 1920m² 

16. There is moisture in my home. What can be the reason?

There are two reasons for he formation of moisture: negative water pressure and positive water pressure.

17. What is positive water pressure?

The source of moisture in the interior space is called positive water pressure. This problem can occur in spaces such as the kitchen, bathroom and dining room, where water vapor is more prevalent. Water vapor turns back to liquid water as it condenses on the walls. This can cause the formation of mold and bacteria, and for the paint to become darker, form bubbles and peel in some areas.

18. What is negative water pressure?

It is the reverse direction pressure occurring in case of insufficient isolation against water coming from soil, roof or environment. The moisture formed on surfaces, inside plaster and walls causes the paint to bubble, peel and mold and bacteria to grow over time.

19. What is the difference between water-based and solvent-based paint?

Paints thinned with water are water based and paints thinned with solvents are solvent based. Water-based paints dry faster and are largely odorless. Their breathing property (vapor permeability) is higher.

20. Why is a primer coat applied?

Primer should definitely be applied on damaged and old surfaces and to new plaster and gypsum surfaces. Primer application enables the surface to be strengthened and the topcoat to adhere to the surface much better. It decreases the amount of paint consumed to make the topcoat.

21. Can I apply paint to stained surfaces?

To cover stains such as oil, smoke damage and pen, apply Camouflage as a primer coat and then a topcoat should be applied.  The reappearance of stains on the surface will be prevented.

22. How many coats should the topcoat consist of?

Even though it depends on the color of the previous paint on the wall and the condition of the wall, generally 2-3 coats are enough.

23. What are the things I should be careful about in metal surface painting?

Some metal surfaces corrode after a while due to oxidation, especially ferrous metals. The result is rust and thepaint film wears out in time. Thus, apply primer and paint that prevent corrosion in order to avoid surface contact with oxygen or use surface-tolerated Polymetal type paints.

24. Which colors discolor more easily on exterior surfaces?

Discoloration is a general problem on exterior surfaces. When the discoloration rate increases, we call it “fading.” Organic colors, such as blue and green, tend to fade faster compared with inorganic colors such as oxide yellow and oxide red. We recommend  you choose topcoat paints with high UV resistance.

25. Why do cracks appear on newly painted surfaces?

The main reason is the application of thicker layers of paint than required. A thinner topcoat will dry faster than thicker undercoats, which may cause the upper paint layer to crack. Moreover, if the surface is not well cleaned there may also be cracks on the surface paint film.

26. Why does the paint look rough and stained?

A rough or stained appearance may result from the final coat being applied on a rough surface, the primer coat not being fully dry or the surface not being adequately cleaned.

27. How can an old brush covered in dry paint be made usable again?

The brush can be made usable by cleaning it with water if the paint is water based and with thinner if the paint is solvent based.

28. What brush size should I use?

It would be more appropriate to make this decision based on the size of the surface. As the surface gets bigger, the width of the brush increases.

29. What should be considered when painting boarded surfaces?

Woods can expand and contract based on temperature changes and this may damage the paint layer. Moving surfaces are also open to corrosion. Thus, on such surfaces more care and attention is required during surface preparation.

30. Do paints contain lead?

Lead is one of the heavy metals that cannot be excreted after entering the body. Lead that may be present in paint can cause health issues by accumulating in the body over time. Thus, we recommend you only use water-based systems especially on interior walls. Consumers may get more detailed information about the paints from the manufacturers.

31. When can a newly applied water-based satin paint be wiped?

The paint reaches a wipe-able hardness in 1 month. The wall can be wiped with soapy water using a soft cloth or sponge.

32. How many days should pass before paint can be applied after rainfall?

Generally, it is recommended to wait minimum of 1 day after rain. But the most important criterion is whether or not the surface is fully dry.

33. What do “satin” and “silky” mean?

These words indicate the degree of glossiness of the painted surface. Satin is semi-matt and silky matt indicates an eggshell gloss.

34. How can I protect surfaces such as natural stone and brick from external conditions?

We recommend you use a titanium impregnation material to protect the surfaces from UV and water.
