Popcorn ceilings can be beautiful, however if damaged, the repair can be difficult. It is a method of putting acoustical advantages on the ceiling, yet is easy to apply and relatively cost effective. If you are repairing a hole in the ceiling, the hole needs repair before attempting to repair popcorn ceiling texture. When the damage has occurred from a water leak, the leak needs to be repaired before the ceiling. Ensure there is no other damage created from the leak, such as drywall or sheetrock that is soaked. If so, replace the damaged areas before repairing the ceiling. Create a smooth area around the damaged ceiling by sanding it smooth and removing the popcorn texture that already exists. Use a good primer coat before beginning to repair popcorn ceiling texture, otherwise the new coat of texture may not adhere to the ceiling. Compare the texture to make a match between the old and the new texture. A texture that is placed into paint is the best way to repair popcorn texture. Avoid using the spray on product. Using the paint-on texture method allows control of the product, in terms of the size and concentration needed. Purchase fine, medium or a coarser-grade to blend with your pre-existing ceiling texture. As you are painting the areas that are in need of repair, ensure you coat the areas that aren't in need as well to coat the ceiling uniformly. Before painting on the texture, an extra piece of wood or drywall can be painted with the paint-texture mixture to determine the balance of paint vs. popcorn. Applying the texture with a roller is great for the majority of areas. When the repair spot is too close to a wall, a brush of edging tool can get into the areas the roller is too large for. Roll once across the damaged area and allow to dry. Make a second or third pass through the area, until the spot matches the texture on the rest of the ceiling. Dry thoroughly before vacuuming ceiling or cob-webbing the area.
