One precaution: You can't paint with it in cold weather. The chemical reaction that transforms the water solution into a durable finish will not take place if the temperature is below 50°. (Conventional oil paints don't stick well in cold weather, either.)
OK, let's get started. Step one...supplies. You need a flat brush, a fan, a small detail brush and a couple of Filberts. A filbert is a rounded edge brush that lets you maneuver the paint easily without going outside the edges. Ultimately buy brushes that you like though, and make them work. Fans allow you to blend, for example. I use fans a lot and it's how I graduate color throughout my images. Everything I paint is by hand....no airbrushing or assistants. I want it to be an expression of me and nobody else. You also need an oil painting medium to mix with the oil paint to make it more fluid, and to speed or slow the drying process. Whichever you prefer. Go to the art store and don't be afraid to ask for help....they'll love helping you! A medium is merely an additive liquid which increases gloss, makes it flow easily, preserves the finish over time, keeps it from yellowing. I personally love Galkyd and Galkyd Lite. If that isn't available, buy a medium that looks like liquid amber and is kind of thick. Don't buy watery looking mediums....too hard to work with.
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.
Is the light neutral, sharp, mystical?
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.
If you are going to paint your home and have decided to do it yourself take a little extra time and spend a bit more money to do it right. Colors are subjective, but the quality of materials and painting tools are not. For this example we are going to go through the process of painting the interior of a typical home. In just about every paint job I did I insisted that customers used an oil based paint on woodwork and doors. Not only does oil paint make wood look and feel better it gives you a superior durable and washable finish that water based latex paint can't. There is nothing worse than seeing a newly painted door or frame ruined by fingerprints and other marks.
Satin paints offer a good combination of easy-clean and moderate sheen. These paints go a step above eggshell in scrubbing ability. They perform and look great in just about any room.
