Healthy Interior Paints for Your Home

It’s no secret that giving your home’s interiors a fresh coat of paint is a quick and affordable way to make some upgrades to the design. However, some interior paints are more problematic for your health than others. In this blog post, we will journey through the fascinating world of interior paints, revealing which paints can best elevate your home's aesthetics while safeguarding your health. From versatile acrylics to the eco-friendly water-based options, and the natural charm of clay-based and lime-based paints, there's an option for all situations. Each type has its unique properties, advantages, and challenges. Read further to reveal the secrets for choosing the healthiest and most environmentally conscious interior paint type for your home. 

Starting with the most common interior paint, acrylic paints offer a durable solution that transforms into a water-resistant finish when dry. These paints get their unique properties from the acrylic polymer emulsion binder. Renowned for their versatility and wide array of vibrant colors, acrylic paints are a favorite among DIYers. They offer a smooth finish and good coverage, making them a practical choice for various interior projects. However, it's essential to be mindful of their potential volatile organic compound (VOC) emissions during curing. Be sure to find the low-VOC or zero-VOC options to minimize negative health and environmental impacts. While acrylic paints provide a durable finish, they may form a tighter film than other paints, which could be a consideration in areas prone to high moisture, such as bathrooms or basements, that might cause wrinkling and peeling of the paint surface. 

Water-based paints, or latex paints as they are commonly called, are a convenient and eco-friendly option for interior painting. Made primarily from water and pigments with vinyl or acrylic related resins as binders, they are a popular choice due to their easy application and quick dry times. This makes them a great choice for DIY projects where a swift turnaround is important. One of the significant advantages of water-based paints is their low VOC content, making them a safer choice for indoor use compared to some oil or acrylic paints. They can be cleaned up easily with soap and water, contributing to a more pleasant painting experience overall. It’s worth noting that water-based paints have improved in terms of longevity and specialized water-based emulsion paints can work well for high-moisture areas like bathrooms. 

Clay-based paints are a natural and sustainable alternative to traditional interior paints. Made from natural ingredients such as natural paints, pigments, and plant-based binders like starches or casein, these paints offer a unique matte finish with a soft, natural texture. Their eco-friendliness is one of their most significant advantages, as they are biodegradable and produce minimal VOCs. Clay-based paints allow moisture to pass through, regulating indoor air quality and creating a more comfortable living environment. Additionally, they provide some sound-absorbing properties, contributing to a quieter space. However, it's important to be aware that they have a more limited color range compared to acrylic or water-based paints and may require more coats for full coverage due to the natural pigments used. This also contributes to their higher price point compared to other paint products.  

Lime-based paints have been used for centuries to create color on interior spaces. Derived from limestone that is fired and mixed with water, these paints offer a unique and breathable finish. Known for their natural antibacterial properties, they create a healthy living environment by preventing mold growth. Lime-based paints are especially suitable for historic buildings or older homes with plaster walls as they enhance and revive the natural beauty of the plaster. While they offer a limited color range, the nuanced hues they provide can be truly captivating. They provide a beautiful depth of color that actually improves over time. However, it's essential to be mindful of their longer curing time compared to acrylic or water-based paints. Handling lime-based paints with proper protective gear and care is also important due to their caustic nature in their wet state. 

Healthiest During Application 

When it comes to paint types that minimize health risks during application, naturally derived options stand out. Clay-based paints take the lead. These paints are made from all-natural materials, free from added chemicals and VOCs. The absence of toxic fumes means they create a safe working environment for both the painters and you and your household members. It's important to note that these paints are typically sold as a dry powder, so avoiding inhalation of the dust is crucial. On the other hand, water-based paints are also a relatively healthy choice. Being low-VOC and easy to clean up with soap and water, these paints are easy on the respiratory system during the application process.  

Healthiest After Curing 

As the paint dries, it’s essential to consider its continued impact on indoor air quality. When selecting paint for a healthy indoor environment, it is crucial to focus on its technical aspects, particularly its breathability and mold-resistant properties. Clay paints, a standout choice, are again particularly noteworthy due to their complete absence of off-gassing or the release of any toxic ingredients throughout their life cycle. This ensures that the air in the living space remains free from harmful chemicals, providing a haven for human health. The breathability of these paints is paramount; they regulate indoor relative air moisture, creating a dry and comfortable atmosphere, which is crucial in preventing mold growth. Mold, a byproduct of high moisture levels, can lead to severe respiratory issues, allergies, and even long-term health problems. A close runner-up in this category is lime-based paints due to their ability to absorb CO2 after curing, which further improves indoor air quality by mitigating the concentration of this greenhouse gas and contributing to a more balanced and healthier living environment. 

Considerations for Acrylic and Water-Based Paints 

When it comes to acrylic and traditional water-based paints, there are several factors to consider when selecting a paint for your home's interior. While these paints can be more affordable options, they will release VOCs into the air, which can pose health risks. However, many paint companies now offer low-VOC or zero-VOC formulas, so it's important to look for these options when making your choice. Opting for paints with low or no VOCs can significantly decrease the exposure to toxic fumes during application and after curing. Additionally, it's crucial to be mindful of the additives in the paint. Some paints may contain biocides or fungicides that can also pose health risks. To ensure a safe and healthy choice, thoroughly read the paint's safety data sheet and look for paints with minimal add-ons. Furthermore, it's important to note that acrylic paints are plastic-based, which contribute to the growing environmental problem of micro-plastic pollution. As you strive to create an eco-friendly home, it's a small change to consider selecting paints that are derived from natural materials, reducing your environmental impact. 

Green Labels for Paint Products 

When seeking environmentally friendly paint options, a variety of labels can serve as valuable guideposts. Among the most prominent are Green Seal and GreenGuard Certification. Green Seal assures products with stringent standards for VOCs, heavy metals, and hazardous air pollutants, while GreenGuard Certification focuses on low chemical emissions, making it particularly relevant for sensitive environments like homes with children, elderly, or auto-immune suppressed individuals. Environmental Product Declaration (EPD) and Cradle to Cradle Certification provide further depth. EPDs offer transparent reporting of the environmental impact of products throughout their life cycle. Cradle to Cradle Certification goes beyond, evaluating a product's holistic performance across five categories of environmental and social safety, making it an ideal choice for consumers seeking products optimized for their health and the planet. Additionally, the Master Painters Institute's (MPI) certification program evaluates paints' performance attributes, ensuring they meet industry-standard expectations. 

Choosing the right interior paint is a pivotal decision that can significantly impact your home's beauty, health, and sustainability. Acrylic paints offer versatility and durability but be mindful of VOC emissions and seek low-VOC options. Water-based paints are a convenient and eco-friendly choice, with low VOC content and quick drying times. Clay-based paints provide a natural and sustainable alternative, while lime-based paints offer a breathable and antibacterial finish. When prioritizing health during application and curing, clay-based paints emerge as the standouts due to their all-natural composition and absence of toxic fumes.  

In the quest for a healthier and more environmentally conscious home, consider labels like Green Seal, GreenGuard, and Cradle to Cradle Certification. These certifications guide you towards products that meet rigorous standards for VOCs, heavy metals, and hazardous air pollutants, ensuring a safer and greener living space for you and your loved ones.
