As of late September 2026, the popcorn ceiling in my back bedroom here in Riverside is the last one in the house, and every fall I think about taking it down myself. The method everyone describes sounds easy: spray a section with water, let it soak a few minutes, run a wide putty knife under the softened texture, and let it drop in wet clumps onto a tarp. It looks like old decorative texture, nothing more. I’ve done most of my own repairs in this house here in California, and the popcorn always looked like one of the easy ones.
Then I read our regional air district’s page for homeowners. The South Coast AQMD says plainly that it “does not recommend a home-owner to perform an asbestos removal due to potential asbestos exposure and/or cross contamination.” That stopped the putty knife.

What EPA says
EPA’s guidance on protecting your family from asbestos is just as direct: “Don’t saw, sand, scrape, or drill holes in asbestos-containing materials.” The catch is that you can’t tell by looking. EPA says the only way to be sure whether a material contains asbestos is to have it tested by a qualified laboratory, and that samples should be taken by a properly trained and accredited asbestos professional.
Why the scraping is the problem
The ceiling sitting there isn’t the risk. EPA’s asbestos FAQ puts it this way: “The risks from asbestos occur when it is damaged or disturbed where asbestos fibers become airborne and can be inhaled.” Its family-protection page lists the ways that happens, and scraping and sanding are on the list: asbestos-containing materials may release fibers when they are disturbed, damaged, removed improperly, repaired, cut, torn, sanded, sawed, drilled or scraped…
