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? Alkyd is an old interior paint made newly popular by a change in solvent - a super-refined petroleum chemical that has almost no odor. It is not a water paint. You thin it and clean brushes with mineral spirits or turpentine, or, if you want to retain the odorless feature, with the new odorless solvent. (Ask the paint-store man for just that, odorless solvent). You can tell when the bucket of paint is getting low when the airless starts pumping really loud and doesn't stop. Simply tip the nearly empty bucket of paint, at an angle so that the mesh filter is covered and wait for the airless to catch up and stop pumping. Sometimes it's just easier to just to replace the bucket of paint with the new one and when that starts going down, pour the excess from the old bucket into the new one.
Our next step is mixing the oil paint. DO NOT SKIP THIS STEP. Obviously you will need to buy some paint thinner, but the most important product you will need is Penetrol $12. Take a plastic quart cup that you will be painting out of and fill it up about three quarters with paint. Now mix in a couple of tablespoons of Penetrol and the slightest amount of thinner. Mix it up with a stick real good and you are ready to go. Why Penetrol? This product is the key to a fantastic looking job. Penetrol will not only smooth out the finish it will extend the time (usually about 20 minutes) before the paint starts to get sticky. This will allow you to apply a glass like finish and eliminate brush marks. We are going to apply two coats here as well so don't glob on the paint. When you are painting the door frames get used to the paint and watch your drips. After about ten minutes or so you will get used to how the paint flows and how damn good your finish looks. Allow to dry overnight before apply second coat. Tip: after you apply the second coat remove the tape and don't allow to dry first. You will get a little paint on your hands from the tape, but deal with it. By removing the tape now you will ensure crisp lines. In some case when you allow the second coat to dry you will pull a bit of the oil paint off. It is not common, but in my opinion why take the chance. Using the Sample Card to Sell the Color Wheel. Of course, paint companies are a little sneakier than traditional marketers. Paint brands know that when you are faced with an array of paint displays (such as in your local hardware/home improvement store), you are most likely to focus your attention on the color wheel display that most attracts your eye. Since the marketers of paint brands understand the human (or perhaps, "animal") attraction to bright colors, they know how important it is to include bright, bold colors in their paint lines and place them front and center in their displays. This is the best way to attract your attention to a paint company's color wheel. If you are not sure of the primer to use on metal, the paint dealer or manufacturer will give you this information, dependent on the type of metal to be painted. Well OK, you don't drink coffee, and the Maxwell House Coffee container was not available, having to resort to next step. This is where some of that extra plastic film and masking tape comes in handy. Taking a loaded Paint Brush, filled with paint, and wrapping it up like a burrito. Using some masking tape, folding all open ends, taping around Brush head for no leakage, ready to unwrap on the next paint application. If storing brush for a longer term, once cleaned, do not shake out excess solvents, wrapping it up, which will enhance shape of Paint Brush, maintaining it's original shape and form.
