If your home has ceilings with so-called “popcorn” texture, you likely have considered having the texture removed. With their sharp peaks and valleys, this ceiling texture was not much appreciated even when introduced in the 1960s, and time has done nothing to make the style any more beloved. There are many reasons to dislike these ceilings.
Painting these ceilings is difficult and requires thick-nap roller covers and a lot of paint since the texture soaks up paint like a sponge. Also, textured ceilings catch and trap dust and are difficult to clean. They can make a room look smaller because the peaks create dark shadows. Further, it’s possible that the texture material contains asbestos or that the paint covering the texture contains lead—both of which pose health risks.
You can purchase a home-based asbestos testing kit that allows you to scrape off a small section of the texture product and mail it to a lab for testing. Results typically take two weeks after the lab receives the sample. Or you can hire an asbestos remediation professional to do this for you. Make sure that the lab is accredited under the National Voluntary Laboratory Accreditation Program (NVLAP).
Paint applied before 1978 may contain lead as an additive. When this paint is disturbed and becomes airborne, it can be ingested and may lead to severe health problems. As with asbestos, inexpensive lead paint testing kits allow you to self-sample by scraping away flakes and crushing them to a fine powder. Many of these home-based lead paint testing kits produce results in less than a minute.
Popcorn ceiling removal creates a great amount of waste. Consider any exposed surface to be a potential recipient of wet, goopy texture product. With that in mind, you may want to remove all lightweight furniture from the room and cover remaining items.
Attach plastic painter’s film to the walls, running the masking tape edge along the juncture between the walls and ceiling. Cover the flooring with the thicker six-mil plastic sheeting.
If you suspect the popcorn texture material contains asbestos or lead-based paint, make sure to wear the appropriate safety apparel, such as a dust mask and work gloves, to continue with removal.
Fill the sprayer with warm water and pump it to raise the pressure. Lightly spray a four-foot square test area of the ceiling and let it sit. If your ceiling only has textured product but no paint, it should readily absorb the water and be ready for scraping in about 15 minutes. If your ceiling was painted with a coat of flat paint or ceiling paint, the water will take longer to absorb and may require multiple light soakings.
After the water has been absorbed, scrape away the texture material. Use the wide scraper at first. Push into the softened texture until the edge of the blade touches the drywall or plaster. Then tilt the scraper to a low angle and push the scraper forward. The textured material should now have the consistency of cottage cheese and should easily come off and fall down. If great force is needed, the material is still too dry; wet it again.
If the sample area removes easily, you can proceed with the rest of the ceiling. Work in similarly small areas, four to 16 square feet. Do not wet the entire ceiling at once, as sections will dry before you can get to them. The narrower scrapers work best along the edges and in corners.
Because you have introduced moisture to the drywall and the room in general, a significant amount of drying time is needed. Drywall has a paper backing and a gypsum core that both hold water for a long period of time. Increasing the temperature and air ventilation will help speed the drying process.
Allow the room to dry for a full 24 hours after removing the ceiling texture.
Gouges, scratches, and shallow holes are an inevitable byproduct of ceiling scraping. Clean your scraping tools and use them to apply spackle or dust-control drywall compound to these areas. Sand smooth with #100 or higher fine-grit sandpaper. Wipe clean. The ceiling is now ready for priming and painting.
If the debris does not contain hazardous materials, you can dispose of it in contractor bags in your home trash pickup.
If the texture material does contain asbestos or lead-based paint, you cannot dispose of it with your regular landfill waste. You will need to obtain a permit and dispose of it separately, typically within a narrow window of time (up to 30 days). Investigate local ways to dispose of hazardous waste safely.
