The existing look and feel of ceiling textures in your bathrooms was probably determined at the time your house was built. Different builders tend to create their own unique patterns based on their preferred technique. The end result depends on what kind of trowel is used to spread the “mud” and exactly how it is applied. Some contractors use a spray gun for quick applications such as a popcorn style ceiling. Others create a combed look by swirling motions with a special comb style trowel. Textures can also be “painted” on to the ceiling with a roller.
When you are doing repairs, you want to try to match the texture that is already present. However, it may be simpler to start over. If you are removing an old ceiling texture to make way for a new look, be aware that popcorn coatings installed before the early 1980’s sometimes contained asbestos. A licensed professional may be needed to remove this material for safety reasons.
Tips for Ceiling Refinishing
Bathrooms are humid environments. The drywall joint compounds and mud that you use to create the ceiling and wall textures should have some sort of fungicide mixed in to prevent the growth of mold and mildew. Also, the paint covering the ceilings should be safe for use in wet areas. This is especially true near any shower. A semi-gloss paint is usually a good choice.
Mud comes premixed and should be very wet when purchased so that it can be easily manipulated. If you must add water, make sure you know exactly what you are doing. Any inconsistency will cause cracks during the drying phase. Work fast and spread the material thin. This will help ensure a consistent layer over the entire drywall
