A lot of novice painters try to use tools that they see on infomercials or some other gimmick advertising. Most of the tools promise something (i.e. straight lines without taping or brushing) that is just not realistic. Another misconception that people have is that the best products are those found in specialty paint stores or the most expensive products. This is not usually the case either. However, you do not want to purchase the cheapest products either. Here is a list of products that I have found over the years to be durable and useful: best wood primer Wooster - The majority of products that I use are manufacture by the Wooster. These products can be found on their website or at any Lowe's location. The plastic roller frames (Sherlock Frame) that Wooster offers are much more durable than the wire frames. The wire frames tend to bend which prevents it from spinning properly. The roller covers produced by Wooster are also well made. You can purchase a package of two or three for fairly cheap compared to what you pay for one at a paint store. It is important to have a quality roller cover. The nap on a lot of cheap roller covers comes off on the wall when applying paint. This is extremely annoying. You have to then spend a lot of time picking this nap off of the wall. I also use a Wooster extension pole. These are particularly nice because they clip into the Sherlock Frame. The extension poles that screw in will sometimes loosen when rolling walls or ceilings so it is nice not to have to worry about that happening. Another good product that Wooster offers is a roller pan. They also have plastic liners for the pan that can be easily disposed of if using latex/water-based paints. Just make sure that the paint is dry before putting any water-based paint product in a trash receptacle. Finally, the brush cleaners that Wooster produces are a good tool to have. One side is a wire brush and one side has what looks like nails coming out of it. Using your fingers or other objects to clean the hardened paint out of brushes can cause permanent damage to the brush so it is a good idea to have the proper tool to help preserve your brush. Purdy - Purdy makes high quality paint brushes. They are a little on the expensive side when it comes to paint brushes, but it is money well spent. Cheap brushes tend to fray a lot easier and can usually only be used once or twice. Purdy brushes can be used multiple times if cleaned properly. They offer all different types and sizes of brushes. I use a Purdy XL 2 1/2" angled brush for almost every job that I do. It works well with latex paints and the angled brush makes it easier to maneuver around corners and other tight spaces. If using oil/petroleum based paints, I suggest using a Purdy Black China Bristle. DAP - The DAP brand produces excellent products for minor crack and hole repair. I use their caulk and lightweight spackling. Just be sure that the caulk that you purchase is intended for the area that you will be caulking. Some caulk can be painted and some cannot. Read The Label! The spackling (Fast N' Final) works well to fill small holes, such as nail holes, in drywall or plaster. I also use it to fill holes left after woodwork (trim, baseboards, etc.) is hung on the wall. It dries fast and is a lot easier to work with than wood putty. You will want to sand or wipe off the area that was patched with a damp cloth after the spackling is dry even though the label says that sanding is not required. I see a lot of botched patching jobs in peoples houses. Its a lot easier to ensure the area is smoothed out before sealing the area with paint.
