Primer paints may be oil- or water-based and are used to seal unpainted surfaces to prevent covering coats of paint soaking in. The appropriate type of primer should be used for the surface being painted - wood, metal, plaster or tiles. There are some 'all purpose primers' available which are designed for two or more of these surfaces. Eggshell - Traditionally refers to an oil-based paint with a silky finish, suitable for interior walls and woodwork. Water-based alternatives are now available. Note: How to use an airless paint sprayer. I'm sure the guy at the rental store showed you how to use the airless (typically with his limited experience of actually painting a house), so hopefully I can offer you a couple new ideas on how to paint your home using an airless paint sprayer. When you first get the airless home, set it in the middle of the area that you would like to start painting. Typically the length of the hose is around 50'. Stretch out the hose prior to painting so that you don't have to worry about unraveling it while you are painting on a ladder. It is a good idea to have a 100' extension cord so that you can bring the airless anywhere you wish to paint without any restrictions. Tip: before you plug in the airless into the extension cord, MAKE SURE THE AIRLESS IS OFF! You don't want the airless to start pumping without paint! Now, when you go to set up the airless, before you turn it on, it's a good rule of thumb to have a second empty bucket next to your bucket of paint. I'll explain why in a second. Place both buckets side by side and place the intake hose (with the wire mesh filter end) into your 5 gallon bucket of paint while the primer hose (usually a lot smaller, about the size of a pencil'ish) is placed in the empty bucket of paint. Before you turn on the machine make sure that the airless is set to prime the machine first. There is a primer valve that you can rotate between prime and paint. A good way to see if the valve is set to prime or paint is to try this little test prior to turning the machine on. While turning the valve clockwise a couple times you will notice that the valve handle will separate from the machine in one position (leaving a slight crack between the valve and machine) while the other position the valve is close to the machine. The position in which the valve is separated from the machine is considered the primer position. Do this multiple times to see what I'm talking about. Don't worry if you keep on spinning the valve, you can spin it a million times in one direction and it won't hurt it.
Set up costs are normally included with any home improvement job, painting separate times for complete exterior painting can essentially cost double, unless agreed before work begins in painting quote. 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? TEMPERATURE OF COLOR. Colors have temperature, referred to as warm or cool. In painting, reds, yellows and oranges are referred to as warm colors and blues, violets and greens are referred to as cool colors. One of the biggest lessons you will ever learn about color temperature though, is that the appearance of color can change drastically depending on its surroundings. For instance, a certain yellow would appear much hotter if it were surrounded by a violet then say an orange. Another important lesson in color temperature: Warm colors will advance in a painting and cool colors recede. Did you know when you walk in a room others size you up in just seven seconds? And, believe it or not, that's before you have said anything. Color is a big part of what makes up your appearance. The right colors will make you look younger, more confident, taller, healthier and bring out your natural beauty. The wrong colors will make you look tired, frazzled and can add extra years.
