Best interior paint
Paint contractors, interior decorators, designers and consumers give Benjamin Moore interior paint high marks. Benjamin Moore Regal Premium Interior (*est. $33 per gallon), Benjamin Moore Waterborne Satin Impervo (*est. $40 per gallon) and Benjamin Moore Regal Aquavelvet Eggshell (*est. $28 per gallon) are all well rated. These paints are durable and washable, go on smoothly and have less odor than most other paints. The eggshell interior paint is recommended for new or previously painted wallboard, plaster and masonry, as well as primed or previously painted wood or metal. However, these Benjamin Moore paints are more expensive than others, which do as well or better in reviews.
Valspar American Tradition is one of Lowe's house brands, and this paint performs much better than Lowe's other house brand, Olympic. American Tradition comes in flat (*est. $19 per gallon), eggshell (*est. $23 per gallon) and satin (*est. $24) in addition to gloss (*est. $26) and semi-gloss (*est. $25). In tests, American Tradition paints are highly mildew resistant -- mildew can be a problem for paint. It is easy to clean, and the semi-gloss and satin finishes hold up to frequent washing and vigorous scrubbing. Soap and water is all that is required for clean-up. Valspar makes this paint exclusively for Lowe's., but it makes a very similar paint, called Valspar Lifetime, which is sold in hardware stores.
Lowe's also has a wider color selection available in its American Traditions Signature Colors line, which come in matte (*est. $25), satin (*est. $29) and semi-gloss (*est. $27). Although Lowe's says this is its higher quality paint, the Signature Color interior paints actually scored a bit lower than the less expensive American Traditions paints.
Home Depot's premium brand, Behr Premium Plus, also receives high ratings in reviews. Behr Premium Plus comes in semi-gloss (*est. $23), satin (*est. $22) and matte enamel (*est. $20), and gets excellent scores for coverage and smooth application. They stand up extremely well to cleaning -- even scrubbing -- but all three interior paints had trouble with fading, so they aren't the best choice for a sunny room. If you are worried about fading, the American Tradition paints are a better choice, although Home Depot's flat paint does clean better than Lowe's flat paint. Behr Premium Plus is a Home Depot exclusive, but Behr sells an identical paint, called Behr Expressions, through hardware stores.
Some less expensive paints do well, but not quite as well as American Tradition and Behr paints.
Dutch Boy Home (*est. $13 to $16 per gallon) comes in flat, satin and semi-gloss. Consumers give this paint high marks for thick coverage. In fact, one homeowner says that it goes on like mustard, thick and creamy. Although reviews say Dutch Boy interior paint goes on nearly as well as higher priced Behr and American Tradition paint, its prone to fading, so it's not the best choice for a sunny room.
In comparative reviews, Sherwin-Williams interior paints don't do quite as well as others, though they are not far behind. Some homeowners like Sherwin-Williams because their retail store representatives know the product well. However, Sherwin-Williams paints are more expensive than the Lowe's or Home Depot brands, but they don't hold up or perform any better.
Martha Stewart sells paint through K-Mart. Martha Stewart Everyday Colors paints come in flat (*est. $18), semi-gloss (*est. $22) and flat (*est. $19). In tests, these paints don't do any better than Dutch-Boy paint, which is less expensive.
Overall, all reviewers agree that buying the best quality paint you can afford is always the smartest choice. Premium paint goes on better and is generally more durable. Reviews indicate that better paints provide a smoother, more uniform appearance and can last twice as long as less expensive paints, making them more economical and less time consuming in the long run.
