Paste and powder paints should be mixed in quantities sufficient for immediate use only, as these materials often become unfit for application if allowed to stand for three or more hours.
Is the light neutral, sharp, mystical?
Anti-condensation paints are used for rooms with humid conditions such as kitchen and bathrooms. This paint is usually formulated to prevent condensation and often includes fungicide.
First consider the size of the painting. The more impressive the subject, the higher the emotions it appeals to, the bigger it is. Religious, mythological paintings are often huge - their massive energy makes you shiver. It is pretty understandable with figurative paintings like Rafael's "The Sistine Madonna", and more subtle with color field paintings of Mark Rothko. People are often overwhelmed with religious tremor in the presence of his artwork, and the size factors in. Also, the subject often calls for larger canvases - battle scenes need space and cannot be fitted into a smaller painting, while some subjects will get lost unless depicted in a smaller size.
In symbolism you do need to look for the hidden meaning, and it's absolutely pointless in pop art, op art, art nouveau or hyperrealism. Each style and genre sets forth its requirements, so brush up on the movement the artist belongs to before you proceed.
Thinking skills (cognition): Thinking is a kind of "inner speech". We talk silently to ourselves to think through things and solve problems. Children in imaginative play begin to develop this skill through talking aloud and explaining everything that is happening in the game. (Think of the children playing in the "home corner" in your playschool and how they tell each other what to do and talk to the dolls and teddies). Slowly, as they become more practiced, this talking changes to become "inner speech" (they think it but don't say it out loud). This is a major foundation for developing thinking and reasoning skills.
Some acrylics are also recommended for exteriors (over the same kinds of materials as vinyl paints). Here it has a big advantage - you don't have to pick your painting weather so carefully. It can be applied on humid days and in cold seasons, so long as the temperature is a few degrees above freezing.
