Plaster. New dry plaster in good condition, which is to be finished with a paint other than water paint, should be given a coat of primer-sealer and allowed to dry thoroughly before being inspected for uniformity of appearance. Variations in gloss and color differences in the case of tinted primers indicate whether or not the whole surface has been completely sealed. If not, a second coat of primer-sealer should be applied. If only a few "suction spots" are apparent, a second coat over these areas may be sufficient. Proper rolling technique: When rolling paint on the wall, get the roller skin evenly loaded with paint and make a V,N or M pattern on the wall, this is to spread the paint across the entire section you will be rolling, then roll back across the section and even out the paint. To properly "lay off" each section, make a final pass of the section applying light pressure to the roller frame arm end of the roller skin and bringing the nap mark (mark created on the pressure applied side of roller skin) across from the beginning of the section to the end of the section, and just repeat all the way down the wall.The V,N or M pattern, will be determine by how far the paint will spread, a V is for less spreading paint and M is for farther spreading paints. Do not "dry roll", which means trying to roll to much of a section at once with very little paint on the roller. Just as important, do not apply to much, if you find you are applying to much, increase the size of the section you are painting i.e. from a V pattern to an N or a N pattern to a M. Acrylic is the second new name for magic in paints. This is also a plastic-in-water. Solid acrylic you know as the beautiful, glasslike Plexiglas and Lucite.
THE BACKROUND. Collect information on the artist and the historical background. To analyze "Guernica" by Picasso, you need to know that Guernica is a town demolished by the Nazi, and you have to read up on the essential features of cubism. To interpret the image of kissing people covered by a piece of cloth in Magritt's "The Lovers", whatever you guess by looking at the painting falls flat once you know that the artist's mother got drowned in the river, and when found, a piece of cloth was wrapped around her head. So, don't rely on your skills and taste too much, there are things you need to KNOW before you start making assumptions. The historical background of the paintings itself is important. Was the artist an innovator, did he start a new trend or movement, whose steps did he/she follow? What experiments was he involved with? How was the painting perceived by the contemporaries? Claude Monet started impressionism with the painting "Sunrise. Impressions". Malevych started suprematism as a development on abstractionism, laying out the new artistic theory of the color, the form and the composition of the painting. The rough lines and raw colors in the fauvist paintings may be traced back to Van Gogh. Do you think there is something new suggested in the painting you are looking at, or is there anything at all distinguishing about it? Another idea keeping Paint Brush moist until the next paint coat is applied (but not leaving for extended periods) is leaving Brush in container, wrapping top with plastic, sticking handle out the top, and taping around the can. This resembles the Maxwell House Coffee Container mentioned earlier. If plastic and masking tape is still not available, and time between coats is not very long, take that sopping wet rag, draping over the top of paint bucket with Paint Brush still in it. This technique works best when using Latex waterborne paints. THE LIGHT AND COLOR. The light and color in the painting will always be dictated by the artist's intention, the concept of the painting. So, consider the sources of color, the time of the day, the emotional impact of light and shades. Lev Vygotsky was very well known and esteemed for his work in researching how children learn and the best methods to ensure that real learning actually happens. He said that "in play it is as though he [the child] were a head taller than himself. As in the focus of a magnifying glass, play contains all developmental tendencies in a condensed form; in play it is as though the child were trying to jump above the level of his normal behaviour." What he is saying here is that in play, a child uses and practices his skills, stretching himself into the next developmental stage.
