Test before you sand.
Pre-1978 trim, old cabinets, radiator paint. A 60-second fluorescence test before the orbital sander comes out.
You can out-think asbestos. You cannot out-think lead.
The weekend reno that took 20 years off.
Your grandparents bought the house before anybody knew. Your parents painted over it three times. You're the one with the orbital sander and the YouTube tutorial, and you're also the first person in this house's 80-year life who has any way of knowing what's in the top coat before you turn it into breathable dust.
What to look at, in order:
Window sill
The single highest-friction interior surface in any pre-1978 home. Sash sliding grinds the paint into sill dust every day for decades.
Kitchen cupboards
Sanded one weekend = years of breathable dust before the next coat seals it. Especially the inside surfaces nobody thinks to check.
Weatherboard exterior
Power-washing, dry-sanding, or stripping painted exterior cladding aerosolizes the paint into your lawn, garden, kid's sandbox, and every wet sock that comes inside afterward.
A husband-wife chemist couple in the archive scraped and heat-gunned the paint off their own house. Both trained chemists. The wife was diagnosed with lead poisoning a few months later. They knew about lead. They thought they could out-think it.
The test that takes 30 seconds.
One drop on any glaze, paint, or surface. UV pen. Glow green = lead. Thousands of tests per kit.
