Care & Supports
Oil paintings do not like direct sunlight. An ideal place for them is a room with ambient lighting. Incandescent bulbs also adversely affect the quality of the painting. Varnish of course protects the paint, but not to that extent. Under the direct sun, it could begin to fade.
Never hang a picture near a stove/oven - it will be very difficult to clean a picture from soot. Air temperature changes may “kill" the painting. Please, do not hang the painting close to the heating appliance. Due to constant exposure to high temperatures, paint may start to crack.
This happens with humidity changes in the rooms. Do not be afraid of this. Place painting on a flat, clean surface with the image down, and wipe the back of canvas with a wet cloth. You do not need “to fill the painting with water”, make sure that the water does not flow from the rag in streams and that no puddles form on the canvas. Just slightly moisten with water - the canvas will immediately stretch evenly. It is necessary to leave the painting in this position until it is completely dry. If this procedure was not enough, then you need to contact a specialist in a framing workshop.
