Green Nontoxic Remodeling Ideas for Common Home Upgrades - Article by Anna Hackman, Editor of Green Talk

(This article was originally published on Green Talk. We told Anna about our new initiative seeking out green bloggers to collaborate on various topics and she happily forwarded this for us to post under our green buildings topic for the months of March and April. We also have another article by Stephen Wade of the 2nd Green Revolution on green cities coming your way. Cheers) 

Vintage Paint Cans We worry about the toxicity of our personal care products, pesticides in our food, and leaching of chemicals.  However, shouldn’t we be equally worried about the chemicals contained in the building products we install in our homes?

I am no stranger to writing about green building products.  Just to give you some background about me for those new to the site, hubby and I built an energy star house starting 2003 with a mission to source only low toxic or non-toxic materials.  Back in the early 2000s this was no easy feat.
Sourcing green building products has gotten so much easier.  To make your journey easier than mine, I did some legwork for you.   Listed below are some chemicals dos and don’ts for these common household upgrades.
Use No or Low Toxic Paint:  There is nothing like paint to give new life to a room. There are many low and non-toxic paint options on the market in every color you can imagine. However, consider one without biocides, fungicides, nonylphenol ethoxylates (NPEs,) and volatile organic compounds (VOCs.)
Why? Paint can contain harmful chemicals such as solvents, biocides (to extend shelf life,) fungicides (to prevent mold,) and VOCs.   The chemicals can cause a variety of health problems such as nausea, eye and respiratory tract irritation, heart, kidney, and lung damage and even cancer.
In addition, a recent study by the Environmental Health Strategies Center and Safer Chemicals revealed that several paint companies failed to reveal nonylphenol ethoxylates (NPEs) in their paint. According to the study, NPEs are highly toxic to aquatic life and are long lived chemicals that can build up in our food chain.  Moreover, NPEs may cause reproductive and development damage in humans.  HealthyStuff.org provides a database of paint products in which NPEs were detected in certain paints.
Note, if your house is older than 1978, lead might be in the paint.  See here on the proper technique to wet sand the walls to reduce dust.
Ventilation is very important when re-painting.  If you can, open your windows.  All paints off-gas depending on the amount of VOCs contained in the product.  For tips for healthy indoor painting, see here.
Non-toxic Caulks, Sealants, and Adhesives:   Adhesives, caulk and sealants are routinely used throughout a house remodel.  For example, adhesives are used for tile installation, and caulk is used around the shower and tub as well as window and doors, and sealants are used on wood floor or stone.
Avoid products that contain “butyl rubber, chlorinated hydrocarbons, formaldehyde, methylene chloride, neoprene and solvent-based acrylic.” Opt for water based latex, low odor, formaldehyde free and fungicide-free products instead.
Kitchen Re-do:  The kitchen is the heart of the home.  Many people opt to re-do their kitchen since according to Remodeling Cost Value Report of 2011-2012, minor and major kitchen remodels garner a 65% (major) to 71% (minor) return on investment.
Choose cabinets that are made of no added formaldehyde-free plywood, particleboard, or medium density fiberboard. The EPA has classified formaldehyde as a probable human carcinogen.
If you are unable to source no formaldehyde added cabinetry, look for cabinetry that contains the Kitchen Cabinet Manufacturing Association logo (KCMA).  KCMA certified cabinetry must meet the formaldehyde emission level set by the California Air Resources Board (CARB.)
All stains, glues, epoxy and sealants should be low toxic as well.
Forget PVC laden Wallpaper and Flooring:  A 2010 study found that PVC laden wallpaper was 2-30 times more likely to contain hazardous chemicals compared to its non-vinyl counterparts, which includes phthalates and heavy metals, lead, cadmium, chromium and antimony.    Such hazardous chemicals have been linked to asthma, birth defects, learning disabilities, reproductive problems, liver toxicity and cancer. Cork, Bamboo, hardwood, and linoleum all tested free of the above heavy metals.
However, be careful when choosing even the above safer flooring option.  Inquire whether or not the product contains formaldehyde adhesives.  Floating cork floors and bamboo can contain formaldehyde.  Opt for no added formaldehyde free or phenol formaldehyde based adhesive products.
Carpet:  New carpet, padding, and adhesive might off-gas benzene, formaldehyde, toluene, and other chemicals.  Opt for low VOC Green Label or Green Label Plus certified carpets, cushions, and adhesives.    Carpet, carpet backing, adhesives, and cushions that contain this seal are independently third party tested for 13 different chemicals.
With any product that you bring into your house, be sure to do your homework.  Read product Material Safety Data Sheets (MSDS) for harmful chemicals; ask questions of the manufacturer, and research alternative low or no toxic products.  Most importantly, ask your congressional leaders to support the Safe Chemical Act so no one has to worry about toxic chemicals in their products.  (For more information about the Act, read her.)
