Lead paints were created using white lead pigments, beginning in Colonial times. Use peaked in 1922 as many homes and buildings were painted inside and out. (Interestingly, the League of Nations had banned lead paint the very same year, but the U. S. decided not to follow suit. Not any normal paint will safely cover lead-containing paint. To make sure that the paint, dust, and fumes are carefully controlled, a special type of paint known as an encapsulant must be used. It's applied over the lead-based paint as a sealant to prevent paint chips or dust from being breathed in or escaping. Lead-based paint does not present a health hazard as long as the paint is not chipping, flaking, crushed or sanded into dust. High levels of exposure to lead may cause lead poisoning and other issues such as anemia and impaired brain and nervous system functions.
On the books, China's paint standards are stricter than those in the United States, requiring that paint intended for household or consumer-product use contain no more than 90 parts of lead per million. But enforcement of the regulations in China is lax.
The Environmental Protection Agency (EPA) estimates the average costs for lead 1 paint "abatement" will range from $8 to $15 per square foot, and the average house can require a minimum of $10, 000 to treat.
Older Homes and Buildings If your home was built before 1978, there is a good chance it has lead-based paint. In 1978, the federal government banned consumer uses of lead-containing paint, but some states banned it even earlier. Lead paint is still present in millions of homes, sometimes under layers of newer paint.
Walls can also be tested for surface lead using a paint testing kit available at your local hardware store. For the test, you rub a solution on the wall. If the solution turns pink, you have lead.
Lead paint can make your home difficult to sell. Any information you know about the presence of lead-based paint must be disclosed to potential buyers. Though that can turn away some shoppers, lead paint disclosure is required by law.
Due to its toxicity, most cities moved away from lead water-supply piping by the 1920s in the United States, although lead pipes were approved by national plumbing codes into the 1980s, and lead was used in plumbing solder for drinking water until it was banned in 1986.
Encapsulants are materials that are applied over lead-based paint to seal the paint to a surface and prevent the release of paint chips or dust. The material may be either a liquid or an adhesive. Encapsulation provides a barrier between the paint and the environment. Conventional paint is NOT an encapsulant.
Lead is a highly toxic metal and a very strong poison. Lead poisoning is a serious and sometimes fatal condition. It occurs when lead builds up in the body. Lead is found in lead-based paints, including paint on the walls of old houses and toys.
According to the EPA, professional lead-based paint removal for the following three options costs about $8 to $15 per square foot or about $9, 600 to $30, 000 for a 1, 200- to 2, 000-sq. ft. house. The average removal project costs about $10, 000.
With this new EPA rule, drilling into your plaster wall which has lead paint on it somewhere in its history now creates a dangerous lead dust hazard.
The average estimated cost of a typical lead paint inspection of a three-bedroom, two-bathroom home ranges from $350 to $450. If the home inspection reveals lead-based paint, then you may need to hire a lead risk assessor to determine whether the paint poses an actual health risk.
What Can I Do If I Have Lead Paint in the House? Immediately clean up any paint chips you find. Keep play areas clean. Don't let children chew on painted surfaces. Clean dust off of window sills and other surfaces on a regular basis, using a sponge, mop, or paper towels with warm water.
Peeling or Checked Paint: Scrape off loose paint and sand to a smooth surface. Sanding or removal of paint containing lead is hazardous. While KILZ ADHESION Primer is formulated to bond without sanding, it is recommended that a small area be tested for adhesion prior to beginning the job.
