Here I just wanted to show how you can transform ugly popcorn (stucco)ceilings without tearing it off - fast, clean and easy.
On the pictures below you may see all stages of "covering" the existing popcorn ceilings with Polystyrene ceiling tiles (this specific model called R-16)
The whole job took about two hours. Tools used - utility knife, putty knife for adhesive (Acryl-Pro from Home Depot ), miter box to cut the crown moldings, measuring tape and pencil.
I used polystyrene crown moldings to cover the gap between the wall and the last tile and was cutting them with utility knife .
Those tiles are easy paintable however I decided to leave them white .
