Lead paint was once used in homes before 1978. In 1978, the United States banned using lead-based paint for residential buildings due to the health risks. Lead paint harms health, especially for young children and pregnant women. When lead paint gets old, it can peel off walls and create dust or chips. Children might come in contact with lead paint and somehow ingest it, which can make them very sick.
Lead poisoning causes serious health problems like learning difficulties, irritability, weight loss, and stomach pain. For pregnant women, lead exposure can cause problems like early birth or slow growth of the baby.
That’s why it’s important to remove lead paint from homes to keep everyone safe, especially kids. However, this job should be left to professionals because we know how to handle and dispose of lead paint properly.
Getting rid of lead paint reduces the risk of lead poisoning and makes the home a safer place to live. But most homeowners don’t have an idea about how to test for lead paint, and we understand that it’s not common knowledge.
That’s why we at Paris Paintings have made it easier for you to learn how to test for lead in paint and how to remove it.
How to test for lead paint in your home?
Here are some ways to test for lead in paint.
1. DIY lead testing kits
1. Select a test kit
You can get two types of DIY lead test kits at hardware and paint stores- rhodizonate-based and sulfide-based kits. The kit you need depends on the paint color. Rhodizonate kits show false positives with red and pink paints, while sulfide kits give false readings on dark paints. These kits are usually affordable, costing less than $100 for multiple tests, which is cheaper than hiring a professional.
So if you have a wall with color red and pink, it’s best to go with sulfide kits, and if the wall is dark in color, go with rhodizonate-based kits.
2. Pick the test spots
Choose areas on walls, windowsills, or baseboards where the paint layer is thickest. Use a utility knife to make a small cut (about a quarter-inch) through the paint layers, exposing all paint layers.
3. Apply the test swab
Test kits come with swabs that must be used correctly for correct results. Mix the chemicals inside the swab by pinching it in specific spots. Then, open the swab tip and press it on the cut paint for a few seconds. Move the swab in a circular motion to ensure contact with all paint layers.
4. Look for color change
Check the swab for a color change. Rhodizonate-based swabs will turn red if lead is present. Sulfide-based swabs will turn dark grey or black. If needed, test multiple layers if the top paint color differs.
5. Verify the results
If the swab doesn’t change color, your paint doesn’t contain lead. To be sure, use the confirmation card included in the kit. This card has lead traces, and the swab should change color when touching it. If it remains colorless, your test is clear, and the paint is free of lead.
Pros of DIY lead testing
- DIY kits are not very costly so lead testing is inexpensive.
- You can get immediate results.
- It is simple to use.
Cons of DIY lead testing
- DIY lead kits may result in wrong results, for example sulfide kits may show a black wall to contain lead even if it doesn’t.
- You have no idea how much lead is present when paint is found to be lead positive.
- Surface layers only are tested through swab testing.
2. X-Ray Fluorescence (XRF)
X-Ray Fluorescence (XRF) is rather a sophisticated method to detect lead in paint. This technique involves using a handheld XRF analyzer that looks like a radar gun but it is handled only by trained and certified lead inspectors.
The XRF analyzer emits high-energy X-rays onto the layers of paint. These X-rays knock electrons out of their orbits, releasing energy that can be tested for the presence of elements. The analyzer detects these energy signatures and gives an exact number telling the amount of lead per unit area (milligrams per square centimeter).
Pros
- XRF testing does not damage the paint layer.
- The analysis is performed on-site and gives instant results.
- XRF accurately measures the amount of lead in paint, even when lead is present in trace amounts.
- It can detect lead through even thick layers of paint.
- XRF is considered the gold standard in lead paint testing as it gives accurate and reliable measurements in a short period of time.
- Approved XRF analyzers must test at the level of 0.5 milligrams of lead per square centimeter, which is the newest action level for defining lead-based paint according to Local Law 66.
Cons
- XRF analyzers are expensive, and you should not be buying an XRF analyzer just for checking the presence of lead in paint.
- Handling an XRF analyzer needs specialized training and certification, so only professionals can use it.
- In some places, the use of XRF devices is regulated and requires a license due to the radiation involved.
3. Paint chip sampling
In paint chip sampling, a small sample of paint from the surface is removed for being tested. This sample is then sent to a laboratory for analysis, where the professionals examine it for lead content using methods such as atomic absorption spectroscopy (AAS) or inductively coupled plasma mass spectrometry (ICP-MS).
If a paint sample has more than 0.5% lead (5,000 ppm by dry weight), it is considered lead-based.
When collecting samples, all paint layers are removed together because older layers sometimes have lead, especially in older buildings that have been painted several times over decades.
After sampling, the area is repaired to avoid lead exposure.
Pros
- Laboratory analysis gives precise and reliable measurements of lead content.
- Paint chip sampling tells the precise amount of lead in the paint sample.
- The method can find lead presence in different layers if many samples are taken from the same area.
Cons
- Removing paint chips damages the painted surface.
- Samples are sent to a lab, and you will have to wait for days to weeks.
- Laboratory analysis can be expensive, especially if multiple samples are tested.
- Collecting and preparing samples requires more effort compared to XRF.

What if your home tests positive for lead in the paint?
It’s a relief if you find that your home has no traces of lead in the paint but sometimes people find lead in the paint of their homes. At the time, you can follow these steps.
Lead exposure is a serious issue but can be managed effectively so there’s no need to panic about it.
- Keep children and pregnant women away from areas with lead paint to avoid exposing them to lead risks.
- Contact an EPA-certified lead abatement contractor who has trained professionals to safely handle lead paint. They can assess the problem and take the right measures to remove any amount of lead present in your home.
- Until you get professional help, minimize lead dust by cleaning surfaces regularly with a wet mop. Avoid dry dusting or sweeping the floors, which spreads lead dust.
- If you can’t immediately find a solution, temporarily seal off or cover lead-painted areas with heavy-duty plastic sheeting.
- Professionals can safely repair and repaint areas with lead paint. They use methods such as encapsulation (sealing the lead paint with a special coating), enclosure or complete paint removal.
- Test for the presence of lead in the other places of your home to ensure that no other areas have lead paint.
- Keep an eye on the health of all family members. If you are doubtful of the symptoms of lead poisoning, consult a healthcare professional.

FAQs
1. Is lead paint dangerous?
Lead paint causes serious health issues, especially in children and pregnant women. It can spread through dry dusting or sweeping and can be ingested accidentally if not removed.
2. How can I tell if my home has lead paint?
You can test for lead paint using DIY lead testing kits, professional services, or X-Ray Fluorescence (XRF) testing. If your home was built before 1978, it might have lead paint.
3.. What should I do if lead paint is found in my home?
Avoid contact with the affected areas, try wet mops, hire a certified professional to safely remove or seal the lead paint, and repair any damaged surfaces.
4. How is lead paint removed?
Lead paint is removed through scraping, sanding, painting, or chemical stripping, but it must be done carefully to avoid spreading lead dust. Encapsulation is another technique where the lead paint is sealed with a special coating.
5. Can I remove lead paint myself?
It’s suggested to hire a certified professional for lead paint removal as it might cause health risks. DIY methods are inexpensive but can be harmful.
