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. Remember this simple rule when thinking about Warm or Cool: Warm individuals have red or gold highlights in their hair. Cool individuals have no red or gold highlights in their hair. That is true for girls and women of all ages. Whether you color your hair, use the color you have now as the basis to determine whether you are Warm or Cool. Congratulations! You are half way towards determining your Season. Airless Tip: If you have somebody who can start masking off the trim, have them start on that while you convert the airless to a new color. When changing colors with an airless paint sprayer it is a good idea to have a second bucket filled half way with clean water. Place the intake hose in the clean water gently without getting the old color everywhere in the water. Take the tip out of the airless and spray all of the old paint out of the hose and back into its original paint bucket. Be careful when doing this that you recognize when the paint starts turning watery. When it does point the gun into the first bucket and spray until it looks pretty clean. It doesn't need to be perfectly clean. When it looks good, clean off the intake line in the clean bucket and get the old color off the intake line. Now place the intake line inside of your new trim paint.
Even if you don't need to apply a coat of primer before your new coats of paint, doing so will always save you money. Whether you use white or tinted primer, a coat of primer is always more cost effective for one simple reason: It is cheaper! In fact, primer may cost as little as half as much as standard paint. If you get it tinted the same as your paint, then it is cheaper by the coat. If you use white, as in the first scenario above, it will also minimize the number of coats of paint you have to apply. Either way it reduces how much paint you have to buy. Do you want to learn more about maximizing your paint color coverage, minimizing your paint usage, optimizing coats, and perfecting your primer? Have plenty of newspaper around. After you clean your brushes wrap them in a plastic bag. Color can make a big difference in your life. I know from experience. Before I learned my right colors, I had a closet full of right and wrong colors. Of course, the colors did not work together and definitely did not coordinate. I had no idea of the difference that coordinated colors can make. Further, I had a drawer full of lipsticks some with gold undertones and some with blue undertones. Technical advancements are constantly being made to improve the life span, durability, wear and performance of exterior paints. The Akrylatfarg range at Ray Munn, for example, is an environmentally sound water-based option.
