For the walls of the hotel the most advisable is to choose the plastic color, which does not give off smell, dries faster and the remains can be removed with the help of water or a damp cloth.
You Can Choose Two Types Of Plastic Paint: Satin And Matt.
Satin paint is shiny and allows a more elegant finish, better resists the passage of 
time and the effects of dirt, although it is a little more challenging to apply than matt, which is why it is not recommended for roofing, which implies a more strenuous activity.
Regarding the matte paint, it is less complicated to apply but has the disadvantage that it gets a little dirtier. However, if the walls have many irregularities, the matt paint dissimulates them better.
Waterproof or vinyl acrylic paint is recommended to paint the walls of the bathroom or kitchen because it is more resistant than the previous ones.
Experts advise that when you are preparing a color, mixing the paint with a pigment, it is best to do it all at once since it is almost impossible to obtain the same tone twice.
It is also not advisable to dilute the paint more than what the container indicates since its capacity to cover will not be the same. And every time you start to paint, you have to remove the paint very well and repeat this operation periodically, to ensure the homogeneity of the liquid and that there are no lumps.
