House Painting Basics

(Post 46 in a series for DIY beginners)
There are just a few basic things that the average home owner needs to know about painting. You can go to your paint supplier and learn all about oil and latex bases for paints, Satin and Eggshell finishes, what paint to use where, and the appropriate cleaners and thinners, but it ain’t gonna do you an ounce of good if you don’t remember these three main rules:
1. Always use a proper primer, or one of the new paints that include a priming agent, for any new surfaces, and that includes new drywall and drywall patches – even the smallest ones.
2. Properly prepare the surface. If it’s a fairly clean painted wall, a good scrub with a degreaser like TSP will do the trick. (Tri – Sodium Phosphate – Sounds like something out of a mad scientist’s lab, but you can get it at the hardware store.) The very best thing to do though, is to give the whole area a light sanding with a medium grit sandpaper, (200 – ish), in a proper flat holder, or in the form of a foam sanding block, and then dust it off.
3. Use lots of paint on your brush or roller. Didja hear me? Use lots of paint! Not so much that it runs down the handle and up your sleeve, or runs down the wall, but you really need to make sure you are using enough paint so that it flows on smoothly. If you are trying to stretch the paint out, and the brush seems to be dragging and not gliding along nicely, you are just making life hard for yourself. The painting is no fun, and the paint isn’t flowing into all the tiny little crevasses and bumps in the material. It might look good to you now, but when it dries you will clearly see the error of your ways.
Anyone doing a renovation is going to spend time consulting with the paint store and will learn many details, but if you always apply these three very basic principles, you will have a far better chance of success. Expensive paint and rollers can never make up for poor preparation and bad technique.
