Walking into a paint store can feel overwhelming. The walls are lined with cans in every color imaginable, and the labels throw around terms like acrylic, alkyd, latex, enamel, and sheen. Understanding what these terms mean is the first step to buying the right paint for your project.
Paint is essentially a liquid coating made of three components. The pigment provides the color. The binder is the glue that holds the pigment together and sticks it to the wall. The solvent is the liquid carrier that makes the paint spreadable and evaporates as the paint dries. The type of binder and solvent determines the paint type, and the ratio of pigment to binder determines the sheen or finish.
Water Based Latex Paint: This is the most common interior paint today. The binder is acrylic or vinyl acrylic, and the solvent is water. Latex paint dries quickly, cleans up with soap and water, has low odor, and is flexible enough to expand and contract with temperature changes without cracking. For interior walls and ceilings, latex paint is the default choice. Within the latex category, 100 percent acrylic paints are higher quality than vinyl acrylic blends. They offer better adhesion, color retention, and durability.
Oil Based Alkyd Paint: Oil based paint uses alkyd resin as the binder and mineral spirits as the solvent. It levels out beautifully, leaving a smooth surface with minimal brush marks. It is extremely durable and resistant to wear, which makes it a traditional choice for trim, doors, and cabinets. However, oil based paint has significant drawbacks. It has a strong odor, requires mineral spirits for cleanup, takes longer to dry, and contains higher levels of volatile organic compounds or VOCs. Many regions have restricted the sale of oil based paint for residential use due to environmental regulations.
Acrylic Alkyd Blends: These are hybrid paints that combine the durability and smooth finish of oil based paint with the easy cleanup and low VOCs of water based paint. They are an excellent choice for cabinets, doors, and trim where you want a hard, smooth finish without the drawbacks of traditional oil based paint.
Milk Paint and Chalk Paint: These are specialty paints used for furniture and decorative finishes. Milk paint is made from milk protein, lime, and pigment, giving a natural, matte finish that is popular for farmhouse and vintage styles. Chalk paint is a thick, matte paint that adheres to almost any surface without primer. Both are used primarily for furniture and accent pieces, not for walls.
The finish or sheen of paint refers to how shiny it is when dry. The sheen affects not only the appearance but also the durability and cleanability of the paint. Higher sheen paints are more durable and easier to clean, but they also highlight surface imperfections more readily.
Flat or Matte: Flat paint has no shine at all. It absorbs light, which makes it excellent at hiding wall imperfections. It is the standard choice for ceilings and for walls in low traffic areas like bedrooms and dining rooms. Flat paint is the least durable finish and is difficult to clean without removing the paint itself. If you have children or pets, flat paint on walls may show scuffs and fingerprints that cannot be washed off.
Eggshell: Eggshell has a very slight shine, like the surface of an egg. It is more durable than flat and easier to clean, while still hiding minor imperfections well. Eggshell is the most popular choice for living rooms, bedrooms, and hallways. It strikes a balance between the forgiving nature of flat and the durability of higher sheens.
Satin: Satin has a noticeable but soft shine. It is more durable than eggshell and easier to clean, making it a good choice for high traffic areas, children rooms, and kitchens. Satin is also a popular choice for trim and doors when you want a softer look than semi gloss. The higher sheen means it shows surface imperfections more than eggshell, so surface preparation is more important.
Semi Gloss: Semi gloss has a significant shine. It is very durable, easy to clean, and resistant to moisture, which makes it the standard choice for trim, doors, cabinets, and bathroom and kitchen walls. Semi gloss highlights every imperfection, so the surface must be smooth and well prepared. It is not recommended for walls with texture or in areas where you want to hide surface flaws.
High Gloss: High gloss paint is the shiniest finish available. It is extremely durable and washable, almost like glass. High gloss is rarely used on walls but is sometimes used for dramatic accent walls, front doors, and furniture. It shows every imperfection and requires meticulous surface preparation.
Different rooms have different demands on paint. Here is a room by room guide to choosing the right paint type and finish.
Living Rooms and Dining Rooms: These are low traffic, low moisture areas where appearance matters more than washability. Eggshell or satin finish in a 100 percent acrylic latex paint is ideal. The slight sheen adds a subtle luminosity to the walls without highlighting imperfections. For formal dining rooms where you want a sophisticated look, flat or matte finish on the walls with semi gloss trim creates an elegant contrast.
Bedrooms: Bedrooms are also low traffic areas. Eggshell or flat finish works well here. If the bedroom is for young children, satin finish provides better stain resistance. Choose a low VOC or zero VOC paint for bedrooms to maintain good indoor air quality, especially for nurseries and children rooms.
Kitchens: Kitchens are high traffic, high moisture, and high grease environments. Satin or semi gloss finish is the right choice for kitchen walls. These finishes can withstand regular cleaning and resist the moisture and grease that are present in cooking areas. Use semi gloss or high gloss for cabinets and trim. Make sure to clean walls thoroughly before painting in a kitchen to remove cooking grease.
Bathrooms: Bathrooms present a unique challenge because of the constant moisture and temperature fluctuations. Use a satin or semi gloss finish that can handle humidity and frequent cleaning. Some paint manufacturers offer bathroom specific paints that include mildewcide to inhibit mold growth. These are worth the premium in bathrooms where ventilation is limited. Always ensure your bathroom has adequate ventilation, as no paint can compensate for persistent moisture problems.
Hallways and Stairwells: These are high traffic areas that take a lot of wear. Satin finish is the best choice because it is durable enough to handle regular cleaning and touching up, and it hides scuff marks better than higher sheens. Choose a color that does not show dirt easily. Mid tone colors work better than very light or very dark shades in high traffic areas.
Children Rooms and Playrooms: Satin finish is the practical choice here. It resists stains, is easy to clean, and can handle the inevitable fingerprints, crayon marks, and spills. Consider a washable paint formulated for high traffic areas. Some manufacturers offer scrubbable paints that can withstand repeated cleaning without losing their finish.
Ceilings: Flat finish is the universal choice for ceilings. Flat paint absorbs light and hides the minor imperfections that are common on ceiling surfaces. Ceiling specific paints are also available. These are formulated to spatter less during application and to have maximum hiding power. They are usually pure white and are less expensive than wall paints.
Trim, Doors, and Baseboards: Semi gloss is the standard for trim and doors. It provides a crisp, clean look that contrasts with the wall finish, and it is durable enough to withstand the bumping and scraping that trim endures. For a more contemporary look, some designers are using flat or matte finish on trim for a subtle, modern effect. This is less durable but creates a striking visual.
Paint quality varies significantly between price points, and the difference is not just marketing. Higher quality paints contain more pigment, better binders, and higher quality additives. This translates to better coverage, better adhesion, longer lasting color, and easier application.
Builder Grade: The least expensive paints, often used in new construction where cost is the primary concern. These paints have less pigment and lower quality binders. They require more coats for full coverage, are less durable, and may show color fading sooner. They are adequate for a quick refresh but are not recommended for a paint job you want to last.
Mid Grade: A good balance of price and performance. These paints offer decent coverage, reasonable durability, and a good selection of colors. They are suitable for most interior painting projects where budget is a consideration but quality still matters.
Premium Grade: The highest quality paints available. They contain premium pigments for better hiding power, high quality acrylic binders for superior adhesion and durability, and advanced additives for flow, leveling, and mildew resistance. Premium paints often cover in fewer coats, last longer, and are easier to apply. The higher upfront cost is offset by better coverage and longer life.
Volatile organic compounds or VOCs are chemicals that evaporate from paint as it dries. They contribute to the new paint smell and can cause headaches, dizziness, and respiratory irritation in sensitive individuals. Low VOC paints contain fewer than 50 grams per liter of VOCs, and zero VOC paints contain fewer than 5 grams per liter.
For homes with children, pregnant women, or individuals with respiratory sensitivities, low or zero VOC paint is worth the additional cost. The difference in performance is negligible, and the improvement in indoor air quality is significant. Most major paint brands now offer low or zero VOC options across their product lines.
Calculating the right amount of paint prevents extra trips to the store and reduces waste. Measure the length and height of each wall in the room. Multiply the length by the height to get the square footage of each wall, then add them together. Subtract the area of doors and windows, which typically do not need painting. This gives you the paintable surface area.
One gallon of paint covers approximately 350 to 400 square feet per coat on a smooth surface. Textured walls reduce coverage to about 250 to 300 square feet per gallon. For most rooms, plan on two coats for full coverage and color depth. When in doubt, buy slightly more than you think you need. It is better to have a small amount left over for touch ups than to run short and risk a color mismatch from a different batch.
Many paint brands now offer paint and primer in one products. These can work well for painting over a surface that is already painted and in good condition with a color that is similar to the new paint. However, they are not a substitute for primer in all situations.
You need a dedicated primer when painting over bare drywall, patched areas, dark colors being painted lighter, stained surfaces, or glossy surfaces that have not been sanded. In these cases, the bonding and stain blocking properties of a dedicated primer are necessary for a successful paint job. Paint and primer in one products are a convenience, not a universal solution.
Buy quality paint. It seems counterintuitive, but premium paint saves money because you need fewer coats, it lasts longer, and the results look better. Cheap paint that requires three coats and needs repainting in two years costs more in the long run.
Buy paint during sales. Major paint brands run promotions around holidays, especially Memorial Day, Fourth of July, and Labor Day. If you are planning a painting project, time your purchase to coincide with these sales.
Consider the color carefully. Changing your mind after buying paint means wasted money and material. Test colors on the wall using sample sizes before committing to a full gallon. Paint a 2 foot by 2 foot section and look at it in different lighting throughout the day.
Buy all the paint you need at once. Mixing all your cans together in a larger container, a process called boxing, ensures color consistency across the entire project. Different batches of the same color can have slight variations that are visible on the wall.
Choosing the right paint involves understanding the types, finishes, and quality grades available, and matching them to the specific needs of each room. Water based latex paint in eggshell or satin finish is the right choice for most interior walls. Semi gloss is the standard for trim and doors. Kitchens and bathrooms need more durable finishes than bedrooms and dining rooms. Premium paint is worth the investment for better coverage and longevity.
Take the time to understand your options before buying. The paint you choose will be on your walls for years, and the right choice makes the difference between a finish that looks beautiful and one that needs redoing.
