Popcorn Drywall Texture
Popcorn texture is one of the most common yet least liked drywall textures on the market. Also known as sprayed acoustic texture, popcorn textures have the appearance of popped corn, thus the nickname. Acoustic popcorn texture is found exclusively on the ceilings of rooms. Generally another type of texture is used on the walls. This texture is commonly found in hotel rooms built before 1990 and even some residential applications from the early 1980's and before.
People are usually more interested in removing this type of drywall texture from their ceilings than they are in new application. If you planning on removing popcorn texture from your ceiling or any area, please read carefully the article how to remove popcorn texture. Acoustic popcorn textures sprayed before 1978 are very likely to contain asbestos. Materials containing asbestos must be removed only by a trained and licensed professional. The government imposes strict regulations on the removal of asbestos. These regulations serve to limit the serious health risks associated with the removal of asbestos.
Spraying popcorn texture requires the use of a special texture sprayer. The same texture sprayers are used when spraying orange peel and knockdown textures. Popcorn textures have Styrofoam as well as other materials added to the drywall mud mixture to create the puffy appearance. A large nozzle is used on the spray gun to spray popcorn texture because of the "popcorn" in the mud. The texture covers the entire surface with a thick layer therefore it will cover many imperfections in the drywall finishing.
If you need to texture a small area because of drywall water damage or other reasons, premixed cans of spray acoustic are available in some home improvement or hardware stores. The method of application is very similar to that of spray paint. Cans of spray texture have written on them the recommended coverage rates however you may want to estimate more material as these cans usually do not cover quite as much as expected. Once the texture is applied it may be painted using an airless paint sprayer. It is not possible to effectively roll or brush paint on the surface of acoustic popcorn texture.
Finally, if you are contemplating using popcorn texture in your home think again. Popcorn texture is not very popular. You may even consult a real estate agent to determine whether acoustic popcorn texture will reduce the appeal of your home to potential buyers. Look into Santa fe texture or skip trowel texture. These two are much more common and accepted. If you are set on having popcorn texture sprayed in your home, make sure to consult a drywall contractor who has experience spraying this type of texture.
