Difficulty: Moderately Challenging
Step1
Determine if your acoustic ceiling contains asbestos. This is important to verify, especially if your home was built before 1980. If asbestos is present, it would be wise to hire a professional contractor to do the job.
Step2
Remove all breakables from tables and shelves in the room.
Step3
Cover all furniture, doors and walls with protective plastic sheeting. Once these items are covered, tape the plastic down to avoid it slipping off. At least four to six inches of the plastic covering on the walls should overlap with the plastic covering the floors.
Step4
Remove any hanging fixtures or ceiling fans and flip the breakers to avoid getting shocked.
Step5
Wear protective gear including a mask, gloves, goggles or glasses, and something to cover your head. A baseball cap will work, too.
Step6
Spray the ceiling with warm water and allow the water to penetrate for about 15 minutes. The water will soften the acoustic. If you are removing a rather large area of popcorn ceiling you may want to invest in a hand-held garden pressure sprayer.
Step7
Scrape away the popcorn texture with a putty knife, being careful not to puncture the ceiling with the sharp corners.
Step8
Wait for the ceiling to dry completely overnight.
Step9
Coat your ceiling seams, joints and any nail or bracket holes with a joint compound. You may need to apply more than one coat of this, depending on your particular ceiling.
Step10
Sand the ceilings with 100 grit sandpaper to smooth out any drywall clumping after the drywall has finished drying.
Step11
Texture the ceiling to match the already existing walls. This can be achieved by special texturing rollers or by using a spray rig.
Step12
Allow the texture to fully dry, at least 48 hours. Then you can prime the ceilings for a fresh coat of paint.
