Preparing the Ceiling

Before you begin painting, proper preparation is crucial.

Clean the Stained Area: Use a suitable cleaner to remove any dirt, dust, or other contaminants from the stained area of the ceiling. This step is vital for the primer and paint to adhere properly.

Use Stain-Blocking Primer: Apply a high-quality stain-blocking primer to the cleaned area. This specialized primer is specifically formulated to prevent the discoloration from bleeding through your new paint.
