My wife and I have a newborn. We have a very old house. Lead is guaranteed to be present. I purchased a lead test kit in hopes of identifying which rooms have lead. As our child grows and starts to go places, as well as restoration efforts continue, I need to ensure that my child's safety is first.
If the sample is not black, but not clear, you are now in a "gray" area. Comparison to the color on the solution one bottle is simply one's interpretation and the test results, personally, I would consider invalid. Don't risk your family.
I then tested the exterior paint. The original color of our home was most likely white, at least that what the paint chips indicate. And that color can be seen as the current paint is bubbling and peeling off. Seeing how other aspects of this home were dealt with, I assume that the surface was not prepared prior to painting.
A sample was taken from the exterior paint and trim around the windows separately. I mixed both the existing paint color and the underlying white paint together, not because I am lazy (though I can be), but because it was impossible to separate. Here was the result:
|Positive Lead Result|
Positive for Lead. Bummer.
