How must I remove Popcorn ceiling ?

All you need to remove popcorn is a spray bottle with water and a metal spackling/drywall spatula, some newspaper on the floor, a vacuum or shop vac, a broom and a dustpan. I don't think the weather will matter if you are working inside a home and the temps are above 40 degrees!

Remove as much furniture as you can. Cover the rest and the floor. Cover your hair and wear safety glasses and a breathing mask. Then put water in a spray bottle and spray well a section at a time. When softened, it will scrape right off. Messy, but easy.Keep your scraper flat, so you do not gouge ceiling.

Hi Gk, I did mine using a spray bottle, good scraper and a cookie sheet.

I sprayed a section twice giving time in between. Then I would scrape it and let it fall into the cookie sheet. In unison, so to speak. It really is pretty easy.

Its going to sort of rain dust for a few days unless you are ready to paint straight away. I found that if I painted while still damp, that dust literally stopped immediately! Here are a few other examples;

i did not cover my floor or tape anything off as I did not let the popcorn hit the floor. Also, weather outside does not matter.

IMPORTANT: you will have a slight texture left on your ceiling. Leave it that way. Do not scrape down to the drywall. Scrape shallow and evenly!!!

Good luck!
