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. Removal. A variety of approaches are used to remove lead-based paints, such as wire brushing or wet hand scraping with liquid paint removers. Your contractor may opt to wet sand surfaces, and must use an electric sander equipped with a high-efficiency particulate air (HEPA) filtered vacuum.
Lead-based paint in good condition is usually not harmful. If your home was built before 1978: Regularly check your home for chipping, peeling, or deteriorating paint, and address issues promptly without excessive sanding. If you must sand, sand the minimum area needed, wet the area first, and clean up thoroughly.
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.
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.
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.
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-based paint is most dangerous when it is deteriorating—peeling, chipping, chalking, cracking, etc. And if you plan to disturb the paint at all, perhaps for a big renovation, a repair, or simply a new coat of paint, you need to take extreme caution, as these activities can create toxic lead dust.
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.
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.
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.
Many of the paints sold in aerosol cans as touch-up paints contain lead. These spray packs are used by car owners to camouflage small areas of damage. A major problem with these spray paints is that people often apply them to objects other than their cars, for example, to household goods, furniture and buildings.
Paint manufacturers have replaced white lead with a less toxic substitute, titanium white (based on the pigment titanium dioxide), which was first used in paints in the 19th century. Titanium dioxide is considered safe enough to use as a food coloring and in toothpaste. It is also a common ingredient in sunscreen.
How long it takes a child to absorb toxic levels of lead depends on the concentration of lead in the dust. Rosen says that in a typical lead-contaminated housing unit, it takes one to six months for a small child's blood-lead levels to rise to a level of concern.
Feed your child healthy foods with calcium, iron, and vitamin C. These foods may help keep lead out of the body. Calcium is in milk, yogurt, cheese, and green leafy vegetables like spinach. Iron is in lean red meats, beans, peanut butter, and cereals.
