Paints in powdered form require the addition of a liquid to prepare them for use. The manufacturer's directions as to the amount of oil, varnish, water, or other vehicle required should be followed.
Matt - Describes paints that give a flat, non-reflective finish. It is ideal for walls and ceilings that are not perfectly smooth.
Store your leftover paint in plastic Rubbermaid beverage jugs or other plastic seal-able containers. Paint left in the can always gets funny after time. Either the can isn't properly sealed of it gets exposed to extreme heat or cold. I like to store my paint inside where the temperature is controlled.
You can put it around a room and probably follow immediately with the finish coat. It can be applied with brush or roller.
STENCILING. You may want designs on the walls, or perhaps even on floors and ceilings, in some of the rooms or hallway. You may buy or make your own stencils, which should be on heavy paper, stencil board, plastic, or metal. Avoid stencils made of lightweight paper which will get soaked when touched by wet paint. Your paint dealer will suggest the best paint for you to use, as it will depend a great deal on the surface over which you want to put the stenciled designs. Generally a heavy paint is used, so that it will not spread under the stencil while you are applying it.
STIPPLING. Whether you desire the effect of stippling (tiny paint dots) as a decorative effect, or if you have a wall which has an uneven surface and you feel you can hide the defect by stippling it, you may accomplish this result very simply.
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.
