The paints may be applied by brush or spray; the small spray attachment for vacuum cleaners is very convenient, especially for painting radiators.
Most of us look to save where we can, especially in this day and economic conditions. House painting is no different, when it comes to saving money. A home exterior weathers from harsh elements of heat, cold, sun, and snow, and exterior paint ages over time needing repainting. Exterior trim, being that of solid wood is normally the first to show signs of painting maintenance. Many times a homeowner happens to call, asking for only painting the trim. Trim paint jobs sound good at first, but have some underlying thoughts may have not been considered. Below are things to consider when considering painting trim only.
Basically what you're looking for is a good, solid foundation of existing paint that is stable and still strongly bonded to the car. Many times an original factory paint job, even after decades will meet these criteria.
Acrylic is the second new name for magic in paints. This is also a plastic-in-water. Solid acrylic you know as the beautiful, glasslike Plexiglas and Lucite.
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.
Use Tinted Primer for Dark Paint Colors.In our second case, suppose you want to apply a deep, dark blue to a beige wall. The good news is that it will be easier to darken a light color than it was to lighten a dark color. In fact, it may only take 2 - 4 coats to get total color coverage in this scenario. The bad news is that if you start out with a white primer you are already moving in the wrong direction. Doing so could increase the number of paint coats you need to 3 - 6... plus the coat of primer! That's a lot of painting!
Main thing to consider when considering painting exterior of your home is; How long do I plan living in this house. If your answer is any longer than 1 year, you may reconsider from painting trim only to painting exterior completely. From a quick glance, fresh trim paint will work from an aesthetic point of view, but not even close from complete protection and value points. Therefore, being fugal painting, does not always mean painting just enough to get by, sometimes costing much more in the long run.
