After using the rest of the paint that my last painter left for touch ups, I noticed a warning that said “Contains crystalline silica which is very dangerous to health. Do not do any abrading, sanding, or scraping. Dust particle extremely dangerous etc”.
Holy geez! I am now afraid to even poke a hole in wall to hang a picture……The paint used are Sherwin Williams 6114 bagel and s.w 7004 snowbound….any info would be appreciated.
Crystalline Silica is a component of almost all paints and also is a component of the Earth (soil, sand, rock, etc). Over exposure can occur but only through excessive sanding, like cutting and/or grinding a granite counter top. I don't think this is a problem for most homeowners.
Sanding anything produces dust that could cause some problems. If you have respiratory ailments/problems you should avoid sanding or wear a good dust mask.
