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.
You scuff up existing paint for two reasons. First, you want to get rid of any oil, grease or dirt trapped in the top layer of paint. This is the stuff that cleaners and degreasers can't get off. The second reason to scuff is to set up a physical bond for the new primer and paint to adhere to. You want to give the old paint some tooth so the new sticks better.
Now that you have the airless paint sprayer and your extension ladders it's time to paint your home. I would highly recommend painting the siding of your home first before painting the trim. The reason being is so you can just spray the house as fast as you can without worrying about painting a section of trim that you already painted. So paint the siding and soffit first followed by painting the trim. Painting the siding using an airless paint sprayer should go pretty fast.
The purpose of this article is to take the mystery out of the process of painting. This article is only written to get you started. I'll write more detailed techniques later. But this article will set you on your way to experimenting and having fun with paint. Ultimately it's like anything in this world. Before you have the knowledge, it's complicated. But once you have it, it's easy! Knowledge is power, and this phenomenon definitely applies to painting. The technical aspects are the easy part. Anyone can do it. You ultimately could be as capable as Monet with practice. We humans can do whatever we decide to do! Deciding WHAT to paint is the hard part. It takes discipline and a singularly focused desire to create one painting after another. For whatever reason, I loved it the minute I started. And I never looked back. I love it today as much as I did over 16 years ago. I never have "writer's block" either as to what to paint. I just paint from my experiences in life. So don't think too hard on it. Paint that apple sitting on the table, or paint the tree in your own back yard, paint your girlfriend in an unusual way. But paint something that means something to you, that's all that matters. Make it funky, make it interesting. If it's abstract, remember that abstract art has long been the most desirable. It's an expression of the individual, make it unique. For those who want realism, take a picture. What's amazing is that once you do it, you realize it's the ultimate escape into happiness. Suddenly you forget your problems for that period of time. You have control, and no one can take it away from you once you are skilled at painting. The process is addicting. But like anything, you must START! And once you do, look out....you'll be hooked.
Now that you have primed the airless, make sure that there isn't a tip in the gun of the airless and bring it over to the empty bucket. Since there is typically cleaning solution in the hose leading to the gun it is a good idea to spray that out until you see thick paint coming out. Once you have thick paint coming out you may put your tip back in. Remember that the tip will have an arrow on one side of the handle that shows which direction it must be in, in order to spray.
Thinking skills (cognition): Thinking is a kind of "inner speech". We talk silently to ourselves to think through things and solve problems. Children in imaginative play begin to develop this skill through talking aloud and explaining everything that is happening in the game. (Think of the children playing in the "home corner" in your playschool and how they tell each other what to do and talk to the dolls and teddies). Slowly, as they become more practiced, this talking changes to become "inner speech" (they think it but don't say it out loud). This is a major foundation for developing thinking and reasoning skills.
Five categories are used to describe VOC content. For guidance, a minimal VOC content is up to 0.29 per cent, whereas a very high VOC content is above 50 per cent. All brands have, where necessary, reformulated their ranges to give minimal VOC content.
