Latex paint is a versatile and flexible paint option that is widely used for both interior and exterior painting. Despite its name, modern latex paint does not contain actual latex rubber. Instead, it uses acrylic resins or vinyl binders suspended in water, making it a water-based paint. It is known for its ease of application, quick drying time, and minimal environmental impact due to lower levels of volatile organic compounds (VOCs) compared to oil-based paints. However, new evidence suggests that paint, including latex paint, may contribute to the global plastics crisis. This has raised concerns about the potential health and environmental risks associated with the use of paint. While latex paint offers advantages in terms of flexibility, breathability, and colour retention, understanding its ingredients and potential risks is crucial as its usage continues to increase.

What You'll Learn
Acrylic latex paint is a type of plastic paint
Acrylic paint is more expensive than latex paint, but it offers greater elasticity, reducing the amount of flaking and cracking. It also has superior adhesion to a variety of surfaces, including wood, metal, vinyl siding, drywall, and more. Additionally, acrylic paint dries extremely quickly, which can be advantageous for smaller areas but may make painting larger areas more challenging.
On the other hand, latex paint is water-based and is known for its ease of application and quick-drying properties. It is also more affordable and better suited for interior projects. Latex paint typically covers with fewer coats and is easier to clean up with just soap and water. However, it may not be ideal for all surfaces and can show brush strokes, requiring extra care for an even finish.
Both acrylic and latex paints are widely used and offer unique advantages. Acrylic latex paint, being a type of plastic paint, has its own set of benefits and drawbacks that make it suitable for specific projects.

Latex paint is water-based
Latex paint is known for its ability to expand and contract with temperature changes, reducing the likelihood of cracking and peeling. This makes it an excellent choice for interior walls and surfaces subject to varying temperatures. It is also formulated to withstand daily wear and tear, making it a durable option for high-traffic areas such as kitchens, hallways, and living rooms. Its resistance to dirt and moisture means that it is easy to maintain and clean, often requiring only mild soap and water.
Latex paint is also known for its vibrant pigments and colour retention, maintaining its hue over time even when exposed to sunlight. It offers a wide range of sheen options, from matte to semi-gloss, allowing for versatility in design and aesthetic preferences. It adheres extremely well to various surfaces, particularly wood and drywall. Latex paint is user-friendly, applies smoothly, and typically requires fewer coats than oil-based paints. Its consistency minimises brush strokes, contributing to a more professional finish even for amateur painters.
While latex paint has many advantages, there are times when other types of paint may be more suitable. For example, in a wet, humid climate, oil-based paints are preferred as they adhere better to shiny or glossy surfaces. Additionally, when painting in cooler conditions (under 50 degrees Fahrenheit), water-based paints can become harder to work with and may not adhere properly. It is always recommended to apply a primer coat when using latex paint, which adds an extra step and cost.

Latex paint is eco-friendly
While paint is a key player in the global plastics crisis, latex paint is considered more eco-friendly than other types of paint. Latex paint is predominantly water-based, using acrylic polymers and polyvinyl acetate as binders. This makes it easier to clean up than oil-based paints, requiring just soap and water. Latex paint is also quick-drying, which allows for faster project completion.

Most importantly, latex paint contains fewer volatile organic compounds (VOCs) than oil-based paints, making it less toxic and contributing to better indoor air quality. VOCs are emitted even after paint dries, contributing to indoor air pollution and poor respiratory health. Eco-friendly paints with low-to-no VOC content, such as Clare Paint, improve air quality and minimize toxin exposure.

Paint is an under-reported player in the plastics crisis
A recent study by Environmental Action, a Swiss-based scientific research firm, found that paint is the leading source of microplastics in oceans and waterways, with 58% of microplastics originating from paint. The largest contributor to this pollution is the architecture sector, which includes paint used on concrete buildings, wood-frame houses, bridges, and other structures. Even the paint used for road striping accounts for 2% of paint-derived plastic pollution.
The problem lies in the fact that acrylic latex paint, which is widely used in homes, offices, and schools, is essentially pigment suspended in liquid plastic. As the paint ages and dries, it cracks and flakes, releasing minuscule plastic fragments into the environment. These microplastics are then ingested by organisms at various levels of the food web, causing harm to humans, animals, and marine life.
The good news is that healthier alternatives to plastic paint exist. Mineral, clay, and plant-based paints are now readily available, offering more sustainable options for consumers. However, it is important to note that transitioning to these alternative paints may require slight adjustments in application and practices.
The paint industry has an opportunity to make a systemic change by finding less harmful and more sustainable alternatives. With the right choices, we can reduce the impact of paint on the plastics crisis and create a greener future for our planet.

Alternatives to plastic paint exist
The use of plastic in paint, particularly acrylic latex paint, has been identified as a key contributor to the global plastics crisis. Acrylic paint is made from a synthetic resin binder called acrylic polymer emulsion, which is essentially liquid plastic. This plastic component, along with various additives, poses a range of environmental and health hazards.
However, there is good news! Alternatives to plastic paint do exist, and they have for centuries. Mineral, clay, and plant-based paints are now readily available and can be used for both interior and exterior applications. These paints can provide superior durability and help minimize mold without the addition of problematic additives. For example, mineral paints penetrate porous surfaces, making them significantly more durable than acrylic paints, which only lightly coat the surface.
Another alternative is to use water-based paints, such as modern latex paints, which utilize acrylic polymers and polyvinyl acetate as binders. These paints are more environmentally friendly and easier to clean up than traditional oil-based or plastic-based paints. They are also known for their vibrant pigments, color retention, and compatibility with various surfaces, particularly wood and drywall.
Some specific products that offer plastic-free paint alternatives include Romabio, which is based on lime, and Keim Paints, which are made from potassium silicate minerals. These products not only avoid VOCs and other hazardous additives but also actively improve indoor air quality by absorbing impurities from the air.
Transitioning to these plastic-free paint alternatives may require slightly different installation practices, but it is a worthwhile learning curve to reduce our reliance on plastics and create healthier and more sustainable environments.
