Do you know that indoor air is three times more polluted than outdoor air? One of the EPA’s top 5 hazards to human health is indoor air quality. This is caused by low levels of toxic dust and particles from old paint on our walls. Many years after the paint is applied, toxins of all sorts enter the air to pollute our homes. These toxins come from volatile organic compounds (VOCs), that used to be considered vital to the performance of paint. Common VOCs are methylene chloride (common in paint strippers), benzene (common in paints), and Ethylene Glycol (common in latex paints). These hazards are in addition to the hazard posed by lead based paint.
New consumer demand as well as new EPA regulations have led to new environmentally friendly paints that are low-VOC and zero-VOC. There are also zero-VOC paint strippers such as Lead-Out Paint Stripper and Franmar’s Soy Gel Paint Remover. Always read the Material Safety Data Sheet (MSDS) for paints and paint strippers before purchasing them to find out the VOC content and other important information.
Technically, zero-VOC paint is any paint with less than 5 grams/liter VOC content as demonstrated by EPA Reference Test Method 24. Although manufactures can claim zero VOC paints, they may still use colorants and biocides which have a low VOC content. Some zero-VOC paints on the market right now include Sherwin Williams Harmony paint line, Benjamin Moore Pristine EcoSpec paint, Green Planets paints, and Ecoshield paint by DunnEdwards.
Low-VOC paints are those with water as a carrier instead of petroleum based solvents. Paints and stains that meet the EPA’s low VOC standards must have less than 200 grams/liter VOC content, and varnishes must have less than 300 grams/liter VOC content. Responsible companies generally market low VOC paints that do not cross the 50 gram/liter threshold, and paints with the Green Seal Standard are certified less than 50 grams/liter VOCs. Examples of low VOC paints include the Benjamin Moore Aura paint line, Ecologic paints by Coverdale, and MAB paints.
It is highly recommended that people remove old paint with an environmentally friendly paint stripper and repaint the surfaces with environmentally friendly paint.
