|Paints and finishes release low level toxic emissions into the air for years after application. The source of these toxins is a variey of volatile organic compounds (VOCs) which, until recently, were essential to the performance of the paint.|
|New environmental regulations, and consumer demand, have led to the development of low-VOC and zero-VOC paints and finishes. Most paint manufacturers now produce one or more non-VOC variety of paint. These new paints are durable, cost-effective and less harmful to human and environmental health.|
Reduced toxins benefit everyone, including those with allergies and chemical
Environment. Reduces landfill, groundwater and ozone depleting contaminants.
Effective. Low-VOC products perform well in terms of coverage, scrubability and hideability (covering flaws on previous coats).
Water-Based. Easy cleanup wtih soap and warm water.
Little or No Hazardous Fumes. Low odor during application; no odor once cured. No off-gassing. Painted areas can be occupied sooner, with no odor complaints.
Not Deemed Hazardous Waste. Cleanup and disposal greatly simplified.
of Non-Toxic Paints and Finishes
The term "non-toxic" is used here in its broadest sense. With paints and finishes, it's more a matter of degree. Even Zero-VOC formulations contain some small amounts of toxins. Here are three general categories of non-toxic (or low-toxic) paints: Natural Paints, Zero VOC, and Low VOC
Natural Paints and Finishes - These are paints made from natural raw ingredients such as water, plant oils and resins, plant dyes and essential oils; natural minerals such as clay, chalk and talcum; milk casein, natural latex, bees' wax, earth and mineral dyes. Water-based natural paints give off almost no smell. The oil-based natural paints usually have a pleasant fragrance of citrus or essential oils. Allergies and sensitivities to these paints is uncommon. These paints are the safest for your health and for the environment.

VOC - Any paint
with VOC's in the range of 5 grams/litre or less can be called "Zero
VOC", according to the EPA Reference Test Method 24. Some manufacturers
may claim "Zero-VOC's", but these paints may still use colorants,
biocides and fungicides with some VOC's.
Adding a color tint usually brings the VOC level up to 10 grams/liter, which is still quite low.

VOC - Low
VOC paints, stains and varnishes use water as a carrier instead of petroleum-based
solvents. As such, the levels of harmful emissions are lower than solvent-borne
surface coatings. These certified coatings also contain no, or very low
levels, of heavy metals and formaldehyde. The amount of VOC's varies among
different "low-VOC" products, and is listed on the paint can or
MSDS. Paints and stains, to meet EPA standards. must not contain VOCs in
excess of 200 grams per litre. Varnishes must not contain VOCs in excess
of 300 grams per liter.
As a general rule, low VOC paints marketed by reputable paint manufacturers
usually meet the 50 g/L VOC threshold. Paints
with the Green Seal Standard (GS-11) mark are certified lower than 50 g/L (for flat sheen) or 150 g/L (for non-flat sheen).
Low VOC paints will still emit an odor until dry. If you are particularly sensitive, make sure the paint you buy contains fewer than 25 grams/liter of VOC's.

|VOC Absorbing Paints - these specialty paints contain an active ingredient that absorbs VOCs like formaldehyde. They remain trapped (cannot be removed) within the product indefinitely. They are:|
Atmosphere Purifying Wallpaint (APP) - a matt/flat finish wallpaint designed to absorb from underlying surfaces and also from the atmosphere in the painted room.
|Non-toxic Wood Treatment
Exterior wood surfaces like decks, railings, raised garden beds, fences and outdoor structures can be protected against water and fungal-borne decay. New mineral-based treatments penetrate the outer layers of wood and form a barrier which serves as an effective wood preservative.
For more information see Eco Wood Treatment.
Most paint strippers are caustic - they work by melting the paint. The active ingredient, methylene chloride, is a potential carcinogen. A new generation of biodegradable paint strippers is now entering the market. They are water-soluble and noncaustic. Some examples are:
- from Specialty Environmental Technologies, in Auburn Hills, MI.
Woodfinisher's Pride - from W.M.Barr & Co, in Memphis, TN.
Ameristrip - from Safe Alternatives Corp, in Ridgefield, CT.
Peel Away - from Dumond Chemicals, in New York. (212-869-6350)
RemovAll and Bio-Wash - from Napier Environmental Technologies in Vancouver BC.
|The active ingredient
in these products is N-Methylpyrrolidone (NMP), an organic solvent. Rather than
burning or melting, the compound chemically changes the paint itself, softening it for easier removal. While considered an organic solvent, NMP is still has potential health hazards. While the toxic effects of MNP on humans have not been well studied, MNP is toxic to the reproductive systems of male and female test animals. Based on the animal tests, you should treat NMP as a potential human reproductive hazard. Pregnant women especially should use extreme care or avoid using paint strippers entirely.
These new strippers are more expensive than their traditional counterparts, and they take longer to work.

Pet birds can be hard on cages - often chewing, scratching or wearing the paint. They can ingest flakes of paint which can be harmful to their health, or can be sensitive to fumes from new paint. If you're planning on re-painting a bird cage, check out our page on Bird-Safe Paints for some helpful tips.
Tips for less toxic, more efficient painting
~ Read the label and product literature: Besides general information, look for:
VOC Content: Usually listed in grams per liter, this can range from 5 to 200. Using a product with the lowest VOC content will yield the lowest overall health risk.
Solids Content: Solids, or pigments, can range in concentration from 25% to 45% by volume. The higher the percent solids, the less volatiles in the paint.
EPA, OSHA, DOT Registrations: When a product has an EPA, OHSA or DOT registration number, this means that it contains toxic ingredients which must be monitored. One way to ensure that you are using a product that is safe both for the environment and the applicator is to seek out products which are not registered with these agencies.
~ Buy the right amount of paint for the job. Before you begin a painting project, measure the area first. Calculate the area to be painted (height x width = total square feet). One gallon covers about 400 square feet.
~ Re-use Turpentine and Paint Thinners. Simply allow used thinner or turpentine to stand in a closed, labeled container until paint or dirt particles settle to the bottom. Pour off the clear liquid and reuse.
~ Avoid Cleaning Brushes and Rollers. Paint brushes and rollers used for an on-going project can be saved overnight, or even up to a week, without cleaning at all. Simply wrap the brush or roller snugly in a plastic bag, such as a bread or produce bag. Squeeze out air pockets and store away from light. The paint won't dry because air can't get to it. Simply unwrap the brush or roller the next day and continue with the job. (This works for water and oil-based paints and stains. It does not work for varnishes or lacquers.)
When you do finally wash you brushes or rollers, wash them in a bucket of water than than in the sink. Pour the used paint-laden water in a sealed container and bring to your local waste depot along with your empty paint cans.
~ Natural Brush Cleaner. Turpentine, made from the resin of coniferous trees, is an environmentally-friendly solvent. It is excellent for cleaning brushes used with oil-based paints, and for cleaning up small drips. Use a short glass jar, filled no higher than the bristles. Add a few drops of dishwashing liquid. After cleaning the brush, rinse with water.
~ Circulate. To reduce the impact of indoor air pollutants, circulate fresh air through your house as often as possible. Avoid the use of spray paints altogether. When painting ceilings, especially, be sure to provide cross-ventilation to remove paint fumes. Fumes rise as paint dries, and so with ceilings the fumes dissipate more slowly since there's no air above the paint. You can reduce fresh paint odors by placing a small dish of white vinegar in the room.
~ Beware Old Lead Paint. Paint manufactured before the 70's contains lead, which has harmful effects on health and development. If the paint is still in good shape, you can paint over it, or leave it be - lead is only poisonous if ingested or inhaled. If paint must be removed in small areas, wet the surface and scrape carefully. Never sand dry lead paint. Clean up with trisodium phosphate (TSP). For large areas, call in a professional certified in lead abatement.
~ Store partially full cans upside down. Leftover paint can be saved for months if stored properly. Make sure the lids are well sealed, then store the cans upside down. This prevents air from getting inside the can and causing the paint to thicken and dry.
~ Solidify old paint. Leftover paint should not be poured down the drain because groundwater supplies may be affected. By removing the lid, the remaining unwanted paint will solidify and then can be treated as solid waste.
~ Remember the BUD rule. BUY no more product than you need. Ask your retailer for help in assessing the quantity you need. USE up all the product you buy. Give leftovers to a neighbor or community organization. DISPOSE of leftovers in a safe, responsible manner.
Consumers can help speed the development and lower the cost of non-toxic paints by choosing products which contain fewer hazardous ingredients. Choosing to use non toxic, environmentally safe paints and stains can also greatly reduce the amount of toxins in the air, water and earth.
