Can you paint a popcorn ceiling and if so, what are the best techniques to use?

Yes, you can paint a popcorn ceiling. The best technique is to use a thick-nap roller to apply a coat of paint in a consistent and even manner. It's important to work in small sections and avoid oversaturating the popcorn texture to prevent it from becoming too heavy and falling off. Additionally, using a primer specifically designed for textured ceilings can help the paint adhere better.
