Painting is one of the most cost-effective ways to spruce up your home, whether it’s the interior or exterior. Did you know that not all paint has an equal creation? We’ve painted hundreds of homes, and we are here to help you take a closer look at the differences between interior and exterior paints and why it’s essential to choose the right type of paint for your painting project.
Basics of Types of Paint
Before we dive into the differences between interior and exterior paints, let’s first review the basics of types of paint. Generally, people categorize paints into three main types: oil-based, water-based, and latex-based.
Oil-based paints
Oil-based paints, which consist of linseed oil or alkyd resins, necessitate the use of mineral spirits or turpentine for cleanup. These paints have earned renown for their durability and their ability to produce a hard and glossy finish.
They find frequent application in high-traffic areas like doors and trim, as well as on exterior surfaces such as metal and wood. However, oil-based paints can be more difficult to work with than water-based options, as they require mineral spirits or turpentine for cleanup and can take longer to dry.
Additionally, they can emit strong odors and high levels of volatile organic compounds (VOCs), which can be harmful to the environment and human health. When using oil-based paints, it’s important to take appropriate safety precautions and follow the manufacturer’s instructions carefully.
Water-based paints
Water-based paints, on the other hand, use water as the primary solvent, making them easy to clean up with soap and water. They are fast-drying and easy to clean up with soap and water.
They are a popular choice for both interior and exterior surfaces due to their durability, low odor, and ability to resist fading, cracking, and peeling. Water-based paints offer a range of finishes, including matte, eggshell, satin, and gloss. Furthermore, you have the flexibility to tint water-based paints to your desired color.
This paint type is also generally more environmentally friendly than oil-based paints, as they have lower levels of VOCs and produce less hazardous waste during cleanup. One thing to keep in mind when using water-based paints is that they can be more prone to water damage, so they may not be the best option for areas with high humidity or moisture.
However, with proper preparation and application, water-based paints can provide a beautiful, long-lasting finish for your home.
Latex-based paints
Latex-based paints are a type of water-based paint that uses synthetic latex as a binder. They also go by the name of acrylic paints because they contain acrylic resins that deliver a durable and long-lasting finish.
Latex-based paints are a popular choice for both interior and exterior surfaces, as they are easy to apply, dry quickly, and are generally less expensive than oil-based paints. They also have a low odor and produce fewer harmful fumes than oil-based paints, making them a safer choice for indoor use.
Latex-based paints offer a wide range of colors and finishes, ranging from flat to high-gloss, and you can easily clean them up with soap and water. However, they may not be the best choice for surfaces that require a hard, glossy finish, such as metal or wood, as they can be more prone to chipping and peeling than oil-based paints. Overall, latex-based paints are a versatile and cost-effective option for most interior and exterior painting projects.
Interior Paints – Overview
When it comes to interior paints, there are several types to choose from. Matte or flat finish paints are ideal for walls and ceilings because they hide imperfections well and have a low sheen. Eggshell and satin finish paints are perfect for high-traffic areas like hallways and entryways as they are more durable and easier to clean. People typically use semi-gloss and gloss finish paints for trim and cabinets due to their high sheen and durability.
Exterior Paints – Overview
Exterior paints have a formulation that withstands the elements like rain, snow, and sun. Specifically intended for outdoor applications, exterior paints possess a thicker and more viscous consistency compared to interior paints, resulting in enhanced durability. These paints offer a range of finishes, including flat, satin, semi-gloss, and gloss.
Difference Between Interior and Exterior Paint
Now that we’ve gone over the basics of types of paint, let’s dive into the differences between interior and exterior paints. While both types of paint share similar components, there are several differences in their formulations that make them suitable for different applications.
Pigments
One of the main differences between interior and exterior paints is the type and amount of pigments used. Exterior paints use more pigments and additives to make them more resistant to fading, chalking, and cracking caused by exposure to the sun’s UV rays. Interior paints, on the other hand, have fewer pigments, making them less prone to fading but more susceptible to stains and damage.
Resins
One more distinction between interior and exterior paints lies in the type of resins utilized. Exterior paints use resins that are more flexible, making them less likely to crack or peel. Interior paints use resins that are more rigid, making them more durable and resistant to wear and tear.
Additives
Additives are another critical component of paint that differs between interior and exterior paints. Exterior paints use additives that help resist mildew, mold, and algae growth, while interior paints use additives that resist stains and odors.
Dry Time
The dry time of interior and exterior paints also differs. Exterior paints take longer to dry because they are thicker and contain more pigments and additives. Interior paints, on the other hand, dry faster and have a lower VOC content.
Level Of VOCs
VOCs or volatile organic compounds are chemicals that are released into the air as the paint dries. VOCs can be harmful to the environment and human health, which is why many paints now have low or zero VOC content. Exterior paints tend to have a higher VOC content because they need to be more durable and resistant to weathering.
Can You Use Exterior Paint Indoors?
While using exterior paint indoors is possible, experts advise against it due to the differing formulations and intended purpose of exterior paint. Exterior paint undergoes specific design to withstand harsh weather conditions, UV rays, and moisture.
Using exterior paint indoors can lead to problems such as strong odors, higher levels of volatile organic compounds (VOCs), and slower drying times, which can result in poor adhesion and cracking of the paint.
Additionally, exterior paints may not be as resistant to fading and wear and tear as interior paints. It is best to use interior paint for indoor surfaces to ensure a durable, long-lasting finish that is safe for indoor use.
Which is Best?
When it comes to choosing the best exterior paint option for your home in Georgia, it’s important to consider the hot and humid climate, as well as the potential for extreme weather conditions like heavy rainfall and strong winds. One great option is acrylic latex paint, which is water-resistant, durable, and can withstand the heat and humidity of the Georgia summers.
Elastomeric paint makes for an excellent alternative due to its specific formulation that allows it to expand and contract with temperature fluctuations. This type of paint aids in protecting your home from moisture and cracking.
Additionally, both of these paint options come in a variety of colors and finishes, allowing you to customize the look of your home to your liking. Regardless of the option you select, it is crucial to seek guidance from a professional painter to ensure the proper execution of the project and long-term protection for your home.
Now, when it comes to choosing the best interior paint option for your home in Georgia, there are several factors to consider, such as the type of surface you’re painting, the level of durability needed, and of course, your personal style preferences.
One popular option is acrylic latex paint, which is known for its durability, easy cleanup, and low odor. Another great choice is eggshell or satin finish paint, which is easy to clean and provides a smooth, subtle sheen that can hide imperfections on walls and ceilings.
For those looking for a bolder statement, a high-gloss finish can add a touch of glamour to any room. Regardless of which option you choose, be sure to select a high-quality paint and consult with a professional painter to ensure a flawless finish.
