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.
Amateur house painters never had as much help as today. Scores of new paints and equipment placed on the market in the last few years make it possible for the weekend handyman to paint his own house almost as easily as a professional. From one-coat paints to disposable blowtorches, everything has been designed to make the job go faster, look better and cost less.
If you decide to do your own body work discuss it with the paint shop first. They'll probably have recommendations on the type of primer you use. Some brands will be more compatible with their primers or color coats. The rule of thumb is to stay within the same brand of paint, both for prep and color. Even the cheapest paint shops typically use a brand name on their intermediate and higher paint jobs. Find out what it is and use the same brand as your primer coat. This will ensure you don't create adhesion problems for yourself down the road.
Remember, you will need to clean the airless in that same fashion before you return the airless back to the rental company.
Painting ceiling does not require premium paint. You can use flat $15 to $20 ceiling paint. I use Sherwin Williams PRO-MAR 200. Painting ceiling requires a lot of physical work and plenty of drop cloths. If you are not up for the challenge or have very high ceilings contacted a professional will prove to be a smart move.
After the siding of your home is painted you can now start on painting the trim. There are a couple different ways you can go about painting the trim of your house. The first way is to mask off all of the trim so that you can merely spray the trim color on to your house, and the second way is to roll the trim by hand. If you are the only person painting the house I would recommend rolling the trim by hand. The reason being is because it takes a long time to mask off all of the trim on your home compared to just rolling the face of the trim boards. If you have multiple people, it would be faster to have the helpers mask everything off while you start spraying the trim color.
Use Plain White Primer for Light Paint Colors. In our first case, if you decide to paint a wall in your house with a light yellow color, but the wall is currently a deep dark brown, you will go through bucket after bucket of paint trying to cover that brown, easily doing 4 - 6 coats or more. But if you put down a coat of white primer first, you could be done after 2 coats of paint.
