The paint on old
houses or buildings may contain lead pigments. White lead
was used in house paints until the mid-1950s, and red lead
was commonly used in primers until the 1980s. Lead chromate
pigments were used in some red, yellow and orange colours,
and calcium plumbate pigment was used on galvanised iron
and steel structures up to the 1980s.
Though not so common, lead test
kits can be purchased from diy and specialist paint stores.
If possible, the old lead-containing paint should be left
undisturbed and simply cleaned and repainted.
