Lessons in asbestos remediation… Scraping popcorn
Remember, your city/province/state/universe may have different rules for how you must handle asbestos. Check them out to see if you can do this yourself or if you have to hire the pros (and their price tags.)
Steps.
1. Buy equipment
2. Prep area
3. Wet & scrape
4. Clean
5. Dispose
1. Equipment – Respirators, Painting Suits, Glasses, ,Gloves, Plastics, Scrapers and Sprayers
Respirators. A simple paper dust mask will not do. Asbestos kills by getting into your lungs. It’s not so bad to get it on your body because you can wash it off but it’s impossible to hose out your lungs. Purchase an approved asbestos mask with a few spare filters. At the end of every day remove the filters and wash the mask with warm mild soapy water and rinse.
Painting Suits. Like I said, you can wash yourself off. The suit takes most of the brunt and is disposable. I vacuumed myself; took off the suit and hung it up; and then removed the mask last. Two or three suits should do the trick depending on the size of your project.
Eyewear. Safety glasses worked for me but in hindsight, I should have gone for goggles. They can be a hassle with fogging up but believe me, popcorn in the eye stings; the lime in it goes straight to your tear ducts and smarts.
Gloves. Good old rubberised gardening gloves with elastic cuffs to keep the stuff out and give you a fairly good grip on the scraper. Cheap too.
Plastics. For my first go around with drop sheets, I bought nice heavy stuff. It was expensive and easy to layout, but turned out to be a waste of money. For my 2nd go around, I bought lighter, cheaper plastic which was a bit “fluffy” to lay-out, but more compact and easier to dispose of than the thick expensive stuff.
Plastic bags were another area where we saved a bit. Check the code in your area but for us, it only required the asbestos be double bagged and well-marked. When we dropped the bags off at the disposal depot, they even supplied stickers to mark the bags as asbestos. Places online will try to sell you the hugely expensive “6 ML” plastic bags which have “Danger Radioactive Asbestos Waste” all over them. I purchased nice and heavy black construction garbage bags which did the job just fine. On the other hand, don’t go too cheap. It would be a shame to spill popcorn all the way out to car because you bought cheap dollar store bags.
Scrapers. I cannot imagine doing the job from a ladder with a hand held scraper. My hat is off to those of you who have done it. I hope the tennis elbow has gone away.
I ended up making my own; a nice 6” wide flexible scraper on a pole did the trick. I took and old aluminum shower curtain pole and beat it up a bit to jam the scraper in the end. Worked like a charm as long as the popcorn ceiling was unpainted. (Read on…)
Spray bottle or bug sprayer? Since I did the whole apartment over the course of a week I used a bug sprayer, the type you get from a garden supply store to apply insecticide to your plants; this was much easier for water application but I found it very easy to over wet an area of the ceiling before scraping. The drywall for our ceilings is coming down and being replaced, so over wetting wasn’t my concern but be aware that too much water will take the backing paper off. If you’re keeping the drywall, you’ll have to work that much harder for that smooth ceiling look before painting.
2. Prep area
Prep, prep, and more prep. Make sure that you have a plan in place; check your local code and have the right supplies; equipment; and setup before you start.
Be prepared to make a mess. This is NOT a clean job. During the process, your walls will get wet and need to be repainted. Even if you spend the time to nicely tape up a plastic barrier wall (can you tell that I did?), the popcorn will fall on the wrong side. The popcorn will fall where it may…
Don’t be cheap or in a hurry. Fully cover the area with plastic drop sheets (took me about 15 minutes) and be prepared to throw them away after you’re done each section. I tried to reuse/recycle my first sheet – what a mess. I first scooped up all the popcorn I could and put it in a bag. Then I tried to move my plastic drop sheet. All I ended up with was a sticky and drying asbestos laden piece of plastic and the more I moved it, the more it shed the bits left behind. At the end, I rolled it up and disposed of the whole mess.
3. Wet & scrape
Spray an area about 4 feet square with water. Let it sit for 5 minutes. While you are waiting the 5 minutes, spray your next 4×4 area. After you’ve finished scraping off the first 4×4, spray the third 4×4 and then scrape the second while it the water soaks into the third. This leaves you with one area soaking while the other is being scraped. Plus, it gives you a little break every 5 minutes.
Painted Ceiling? Well, you’re not completely screwed. One of the rooms in the condo had previous water damage, and the ceiling had been painted. It was by far the hardest space I had to deal with, so I saved it for last. I still sprayed it with water, but because of the paint, it didn’t soak well and as a result, much of the scraping was “dry”. Dry scraping was much slower and dustier. Speaking of dust, keep that small mister bottle handy. A few pumps into the air and everything falls to the plastic.
4. Clean
Remember that drop cloth you spread on the floor before you started? Roll it up and tuck it into one of those heavy garbage bags. After you fill each one, double bag it and tape it closed.
After all the ceilings are scraped and asbestos bagged, give the place a good vacuum and wipe down the ceilings.

5. Dispose
Contact your local waste disposal service and find out where they take asbestos garbage. Ours 40 minutes away. We drove in, stated we were disposing of asbestos, got some fancy stickers to paste on the bags, threw them in the marked dumpsters, and then drove out $40 poorer. A bargain compared to the thousands professionals would have charged us.
Et Voilà!
Now stand back and bask in the glory of a job well done. Popcorn is gone and asbestos is remediated. Was it harder than you thought? Not really but the preparation was the key. A little elbow grease and you’ll have nice smooth ceilings that will give you an updated look and style.
Congratulations; now; what’s next on the job list……
