Painting with a roller looks easy. Believe it or not, it takes a considerable amount of hand-eye coordination to achieve professional results
I'm embarrassed to say that I've never painted walls or woodwork. My dad always did it, and I had no interest in helping. I now need to know how to paint, as I just bought my first home. I tried painting the walls in my living room and made a huge mess. The paint looked good going on, but now looks transparent. Can you instruct me how to paint interior walls, ceilings and woodwork? I'm so frustrated and am reluctant to call my dad.

Thanks for asking for my advice, but your dad is the man you should consult -- assuming, that is, that you've got a great relationship with him. As a dad, I can tell you that he'll be honored to hear his daughter ask for a demonstration of his painting mastery. Do it. Make the call now.
In case he's out and can't pick up the phone, I'll fill in some basic principles. Note that there's much more to painting than I can convey in this tiny column, and the best way to learn is to be in the same room as the teacher. You need to see the actual techniques.
Let's start with painting tools. Professional painters typically purchase the best brushes, roller frames, roller covers and so forth. Why? Because these tools produce better results faster.
Make sure you match the brush with the paint. Polyester brushes are typically used with latex or water-based paints. Angled brushes for many tasks, and they are a must for painting woodwork trim and cutting in paint where one color is up against another. I'm not a fan of the sponge brushes, but you may end up liking them.
Roller covers come in different thicknesses of the nap. I prefer to use one that has 3/8-inch nap for painting walls and ceilings with a flat finish paint. If you're painting coarse masonry surfaces, you'll want a 1/2-inch or thicker nap. If you're painting a smooth surface with a high-gloss or semi-gloss paint, you may want a short-nap roller cover that has 1/8 or 1/4-inch nap. Smaller nap produces less texture in the dried paint.
Not all paint is created equal. You get what you pay for. Remember that paint is, for the most part, glue with color in it. There are special paints for different situations. For example if you want to know how to paint drywall, especially new drywall, you'll quickly discover that you need to use special primers that both prime and seal in one step. Some newer finish paints make the claim of not needing these primers, as they include the heavy pigments and porosity sealers in the finish paint product.
The problem with your poor coverage could be related to the quality of the paint, your painting technique, or both. A considerable amount of the volume of many water-based paints evaporates from the surface you paint, leaving behind a very thin film of pigment and the chemical glue. If you spread the paint too thin as you work it, when the paint dries there simply is not enough pigment and adhesive to cover what was on the wall before you started.
Most paint cans have printed on the label the recommended coverage rate. For many years a gallon of latex or water-based paint would cover about 300 to 400 square feet of surface area. When you do the math, you'll discover that one gallon of paint should cover only the walls in a small 10-foot by 12-foot room that has 8-foot ceilings.
Be sure you read the label on the paint can before you start your next job. If you want the best results, follow the instructions. When they say to apply to a clean, dry, dust-free surface, they mean it. Remember, paint is glue, and for it to stick well, the surface needs to be clean.
When painting ceilings, you'll discover that adjustable fiberglass extension poles will save you time. Using this accessory, you can paint ceilings without making numerous trips up and down a ladder. The same is true for walls. I have numerous adjustable extension poles that screw into the base of the roller frame.
Cleanup after the paint job is done is an art all itself.
You can ruin a high-quality paintbrush in no time if you clean it incorrectly. Never hold the brush up-side-down in a stream of water. This drives paint higher up into the bristles and fans them out. It's better to dip the brush in a can of soapy warm water and shake it back and forth in the frothy mix. Do this with the rinse water as well until the water remains clear as you shake the brush.
If your house has a septic tank do NOT clean your brushes indoors. You don't want latex paint residue entering the septic tank or leach field. Clean your painting equipment in a large bucket indoors if necessary and dispose of the cleaning water safely outdoors in a sand pile or other media that will capture the paint and not pollute the soil or groundwater.
