Painting trim is normally done by roller and brush, not sprayed, so more manual labor is required painting trim, and most cases costing 60% of the total exterior painting job.
Solvent or oil-based paints are used where a tough, durable finish is required for interior and exterior timber, masonry and furniture - although, as mentioned above, the new generation of acrylics and multi-surface paints offers viable alternatives. In general, brushes need to be cleaned with turpentine or white spirit.
Limewash - Made from slaked lime and water, this paint is good for porous surfaces such as brickwork, render and plaster and gives a chalky finish. It is available from specialist companies.
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.
Better still, you don't have to spend hours getting ready and hours cleaning up afterward. Premixed paints, electric-drill attachments and self-dispensing calking guns make short work of preparation. Cleaning up is a soap-and-water job for the rubber paints, or a quick dip in special cleaners for the oils. Disposable dropcloths and paper paint pails are used once and thrown away.
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.
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?
