Volatile organic compounds (VOCs) are common air pollutants found in many household items, such as paint, cleaning products, and furniture. These compounds can off-gas into the air, releasing potentially toxic chemicals. Safe Seal by AFM Safecoat is a water-based product designed to seal in and reduce VOC emissions from porous surfaces, such as plywood, particleboard, and pressed wood. It is applied with a brush, roller, or sponge and dries clear, although it may remain slightly tacky. While Safe Seal can help mitigate VOCs, it is not suitable for all surfaces and should not be used over paint. Other products, such as primers and synthetic sealers, are also available to help reduce VOCs and improve indoor air quality.

AFM Safecoat Safe Seal is a sealant that can be used to reduce VOCs from plywood, particleboard, and pressed wood
Volatile organic compounds (VOCs) are common air pollutants that are often found in paints and cleaning products. These compounds can off-gas into the air, releasing toxic chemicals that can be harmful to human health. To reduce exposure to VOCs, it is recommended to use low-VOC or zero-VOC paints and sealants.
AFM Safecoat Safe Seal is a sealant designed to reduce VOCs from various materials, including plywood, particleboard, and pressed wood. It is a waterborne, low-gloss primer/sealer that is applied to porous surfaces to reduce toxic outgassing. Safe Seal is particularly effective at sealing in formaldehyde, a known carcinogen, and other VOCs that off-gas from composite wood products. The product has been on the market for over 40 years and is often recommended by doctors for chemically sensitive patients.
Safe Seal is applied with a brush, roller, or sponge and allowed to dry completely for about two hours. This process is repeated for a total of 2-3 coats. It is important to note that Safe Seal is not suitable for surfaces that are often touched or handled, as it remains slightly tacky even when cured. Instead, other products like Safecoat Hard Seal or Acrylacq are recommended for exposed wooden surfaces.
While Safe Seal can effectively reduce VOCs from plywood, particleboard, and pressed wood, it is not a finish sealer. It is meant to be used on surfaces that are not frequently seen or touched, such as behind cabinets or under furniture. Safe Seal is a useful product for reducing VOC exposure, but it should be used in conjunction with other measures to create a healthier indoor environment.
Overall, AFM Safecoat Safe Seal is a reliable option for those seeking to reduce VOCs from plywood, particleboard, and pressed wood surfaces. By following the recommended application process and considering the limitations of the product, individuals can effectively minimise VOC exposure and improve indoor air quality.

Safe Seal is not suitable for painted surfaces or veneer/melamine
Safe Seal is a water-based product by AFM that is used to seal in formaldehyde and other VOCs from porous composite wood such as plywood, particleboard, and pressed wood. It is not suitable for painted surfaces or veneer/melamine.
Safe Seal is not recommended for use over paint. It is designed to be used as a primer underneath paint. It is important to note that Safe Seal is not a finish sealer and is only meant for surfaces that are not often touched or handled as it remains slightly tacky even after drying.
If you are looking to seal in VOCs on painted and finished surfaces, there are other products available that will provide a harder seal and are more appropriate for surfaces that get a lot of use. These include AFM Hard Seal and AFM Acrylacq for furniture and other touchable surfaces, and AFM Polyureseal BP for flooring.
Additionally, Safe Seal should not be applied to non-porous surfaces such as MDF or pressed wood with a veneer or skin of melamine. It is intended for use only on exposed edges where raw MDF or particleboard/pressed wood is visible.
To address VOCs on painted surfaces or veneer/melamine, it is recommended to explore alternative products specifically designed for these types of surfaces. Safe Seal is specifically formulated for porous composite wood and may not effectively seal in VOCs on other types of materials.

VOCs are volatile organic compounds that are common air pollutants found in paints and cleaning products
Volatile organic compounds, or VOCs, are compounds that have a high vapour pressure and low water solubility. They are emitted by a wide range of products, including paints, lacquers, cleaning supplies, pesticides, building materials, and furnishings. VOCs are common indoor air pollutants that are frequently found in household products and can have adverse health effects. For example, chronic exposure to hazardous VOCs is associated with neurological disorders, including dementia and tremors.
Paints, varnishes, and wax all contain organic solvents, as do many cleaning, disinfecting, cosmetic, degreasing, and hobby products. Fuels are made up of organic chemicals, and all of these products can release organic compounds during use and, to some degree, during storage.
The concentration of VOCs is consistently higher indoors than outdoors, with levels up to seven to ten times higher inside homes. This is often due to poor ventilation, as VOCs are added to indoor spaces faster than they can escape. Some VOCs, such as semi-VOCs (SVOCs), settle onto surfaces and are absorbed by dust, leading to harmful health effects when inhaled or ingested.
To reduce exposure to VOCs, it is recommended to use products with low or zero-VOC content, improve ventilation, and follow manufacturer instructions for proper use and disposal of products containing VOCs.
Safe Seal is a product by AFM that can be used to reduce VOCs from off-gassing in indoor spaces. It is a water-based sealant that can be applied to materials like plywood, pressed wood, and particle board that contain toxic VOCs such as formaldehyde. While Safe Seal can be used to seal in VOCs on certain surfaces, it should not be used over paint. Instead, it can be used as a primer underneath paint.

Zero-VOC paints have fewer than 5 grams of VOCs per litre, while low-VOC paints have less than 50 grams per litre
Volatile organic compounds (VOCs) are common indoor air pollutants that are frequently found in household products and can cause adverse health effects. Paint is a common household product that contains VOCs. When paint is applied to a surface, it begins to off-gas, releasing VOCs into the air. This process of off-gassing can continue for months, and studies have shown that only about 50% of VOCs are released within the first year.
To reduce exposure to VOCs from paint, some people choose to use low-VOC or zero-VOC paints. Low-VOC paints are defined as containing less than 50 grams of VOCs per litre, while zero-VOC paints contain fewer than 5 grams of VOCs per litre. These paints tend to be water-based and have a significantly lower odour than traditional oil/solvent-based paints. They are also better for the environment, as VOCs contribute to air pollution and can enter groundwater, affecting plants and wildlife.
While low-VOC and zero-VOC paints have fewer VOCs, it is important to note that they may still contain other toxic ingredients. Some common ingredients to look out for in conventional paints include methylene chloride, formaldehyde, and heavy metals like mercury and cadmium. Formaldehyde, in particular, is a known carcinogen.
To further reduce exposure to VOCs, it is recommended to use sealants like AFM Safecoat Safe Seal, which can be applied to surfaces like plywood, particleboard, and veneer cabinetry to prevent VOCs from off-gassing into the air. However, it is important to note that Safe Seal should not be used over paint, but rather as a primer underneath. Additionally, proper ventilation during and after painting is crucial to minimising exposure to VOCs.

Green Seal certification restricts VOC content and requires an emissions evaluation to ensure products do not off-gas hazardous chemicals
Volatile organic compounds (VOCs) are common indoor air pollutants that are frequently found in household products and can cause adverse health effects. Green Seal is a third-party certification that ensures products are safe for both people and the planet. It is recognised globally as a gold standard for protecting people and the planet. The certification has been raising the bar for ecolabelling worldwide for 35 years.
Green Seal sets limits on VOCs in two ways: content and emissions. It restricts VOC content in the product formula, and also requires an emissions evaluation to verify that the product does not off-gas hazardous chemicals during a specified period after the initial application. This provides an indicator of safer air quality for building occupants. The certification also restricts the VOC content of colourants added at the point of sale. Any colourants used with Green Seal-certified paints cannot cause the final product to exceed the category VOC limit by more than 50 grams.
Green Seal's paint certification is the only mark in the marketplace to qualify products for both LEED v4.1 low-emitting materials credit requirements and Amazon's Climate Pledge Friendly badge. This makes it simple for health-focused buyers to identify safer products. Green Seal's original leadership standard for paints and coatings, published in 1993, was the first to set limits on VOCs.
If you are concerned about VOCs in your home, you might consider AFM Safecoat Safe Seal or Safecoat Primer. The company has a range of VOC sealant products that promise to reduce potentially toxic chemicals coming out of new paint, new furniture, cabinetry, etc. Safe Seal goes on clear and can be used to seal veneer cabinetry. However, it dries very quickly, which can make it challenging to apply.
