How to clean a popcorn ceiling without knocking the texture loose

Step by step: how to clean a popcorn ceiling without knocking the texture loose

Safety first. Older popcorn and other textured ceilings can contain asbestos. Do not brush, vacuum, scrape or wet a ceiling you have not confirmed is asbestos-free. Work from a stable ladder, keep three points of contact, and wear glasses so falling texture does not get in your eyes.

1. 1

   Find out what the ceiling is made of

   If your home is new enough that you know the texture is modern, or a lab test has come back negative for asbestos, go ahead. If you do not know, leave it alone and have a sample tested by an accredited asbestos professional before you clean, scrape or paint it.

2. 2

   Clear and cover the room

   Move furniture to the middle of the room or out, and lay a drop cloth under the area you will work on. Even gentle cleaning drops a little texture. Turn off ceiling fans and close vents to the room if you can.

3. 3

   Set up your ladder safely

   Open a step ladder fully on a level floor and lock the spreaders. Do not stand on the top step. Work an arm’s length of ceiling at a time and move the ladder rather than leaning out.

4. 4

   Roll away dust and cobwebs

   Run an extendable lint roller, or a paint roller wrapped in painter’s tape sticky side out, lightly across the ceiling. Barely touch the surface and let the tape pick up dust and webs. Replace the sheet or tape as soon as it looks gray.

5. 5

   Vacuum with the brush barely touching

   For heavier dust, use the soft brush attachment on low suction and hold it just at the tips of the texture. Pressing in or using the bare wand will pull off chunks. Work in straight, overlapping passes and stop if you see bits falling.

6. 6

   Mist small stains lightly

   For a small water or smoke stain, mist the spot from about 12 inches with a fine spray until it is just damp, not wet. Let it dry for a few hours and repeat once if needed. Soaking the texture softens it, and it can sag or fall off.

7. 7

   Seal stains that will not lift

   If a stain is still visible after two light treatments, spot prime it with a stain-blocking primer made for ceilings, then touch up with flat ceiling paint. Fix the leak that caused a water stain first, or it will come back.

8. 8

   Clean up the floor carefully

   Fold the drop cloth inward to trap the fallen bits and shake it outdoors, or wipe the floor with a damp cloth. For a ceiling you have confirmed is asbestos-free, a normal vacuum is fine.

Does your popcorn ceiling contain asbestos?

You cannot tell by looking, so an older textured ceiling should be tested before you clean or disturb it. The EPA lists textured paint and patching compounds used on walls and ceilings among the places asbestos may be found in homes.

The EPA’s advice for homeowners is that if you are in doubt, treat the material as if it contains asbestos and leave it alone. Undamaged material is best left undisturbed, and the agency says not to dust, sweep or vacuum debris that may contain asbestos, and not to sand or scrape it. Sampling is best done by an accredited professional, who can also tell you whether to encapsulate, repair or remove it.

Old ceiling paint is a second concern. The EPA notes that homes built before 1978 are more likely to have lead-based paint, so do not sand a painted popcorn ceiling in an older home without testing it.

How do you remove water and smoke stains from a popcorn ceiling?

Start with the lightest treatment and stop as soon as it works: a fine mist and time first, a stain blocker second. Scrubbing is never an option on popcorn texture.

Wear safety glasses when misting overhead. Never mix bleach with ammonia, vinegar or other cleaners, and keep the room ventilated. For a bathroom ceiling, see cleaning mold off a bathroom ceiling.

When should you call a professional for a popcorn ceiling?

Call a pro if the ceiling may contain asbestos, if the texture is loose or falling in sheets, if a water stain covers a large area, or if the ceiling is too high to reach from a step ladder.

Ladder work overhead is where most of the risk is for a DIY clean. OSHA’s ladder safety sheet says to keep three points of contact while climbing, face the ladder, use it only on a stable and level surface, and not to stand on the top step unless it was designed for that. Looking up while reaching makes it easy to lose balance, so move the ladder often.

If you plan to scrape the texture off entirely, that is a remodeling job, not cleaning: test for asbestos first and follow the professional’s advice.

Mistakes to avoid

• Brushing or vacuuming an older ceiling before knowing whether it contains asbestos.
• Pressing the vacuum wand into the texture and pulling off chunks.
• Soaking a stain with spray until the texture turns soft and sags.
• Painting over a water stain before fixing the leak.
• Standing on the top step of the ladder to reach one more patch.
