I used the shade "Egg Yellow 3589 (750ml)". The paint is average for decorative finishes. The coverage of this particular color isn’t the best, and you may need 2–3 coats to achieve the desired result, whether using a roller or a brush.
Another problem I noticed is that although the lid is plastic and closes properly, after a few days a crust forms on the surface of the paint inside the tin, and you have to remove it each time. I use many different paints from many manufacturers every day, and this is the first time I’ve encountered this with chalk paints.
After a while, this particular paint started thickening in the tin even faster (the lid was closing tightly, as confirmed), and not only forming a crust but also developing mold on the surface, eventually going bad completely. I had to throw it away before I’d managed to use even half of it.
I should note that I use many other chalk paints from various manufacturers, and this is the first time I’ve noticed this happening.
By far the best so far are Maxi-Decor.

The same poor result on both untreated and polished surfaces. Very watery paint that even drips with color on the brush tip. No coverage, especially with a wet brush as recommended for applying chalk paint, it doesn't even hold the color on the special brush.

The paint is very watery, resulting in it dripping from everywhere and leaving marks that cannot be fixed no matter how many times you go over them. It's a big disappointment since I have used chalk paints before and they were much better and easier to use. I wouldn't recommend it

The shade is beautiful! The first coat left some gaps, dried in an hour, and then I applied another coat as recommended. The product is thick, I applied it with a brush and it didn't give me any trouble. The second coat dried easily, the material I painted was melamine in very good condition and the original color was brown. It takes over 24 hours for the paint smell to go away. The result is matte. I didn't try sanding it afterwards for a more vintage effect
