Following World War II, the housing boom for returning Gis and their families started using a relatively new product called drywall, wallboard, or gypsum board. This was more affordable than lath and plaster and less expensive. It was used in most residential and commercial construction during that time. One of the binders used in this product was asbestos.
Asbestos is a fibrous silicate commonly used prior to 1980 in the production of drywall and many other materials. It is fireproof, offers good insulation, and provides strength to the drywall. We now know that if ingested or inhaled, they are extremely hazardous to health. It’s important to seek out asbestos abatement services to handle the removal correctly.
If your building was constructed between 1940 and 1980 there is a good chance that it contains asbestos in the drywall and possibly other areas. It is most commonly used in the joint compound that seals the panels, sometimes referred to as “mud”. However, it has also been found in the sheetrock, tape, and surface textures. It was also used in some flooring options, popcorn ceilings, and, of course, insulation. You may be surprised to know that asbestos is still used in many products that are imported from other countries including asphalt roofing on commercial buildings, gaskets, and brake shoes.
Considering DIY Renovation?
If you are considering a DIY renovation project and your building fits the timeframe, it would be a good idea for you to have the walls and other elements tested for asbestos. It can be handled visually through a visual area estimation as well as a point count, which is more detailed. These tests can be performed by an asbestos abatement contractor here in Calgary. There is also the option of doing the test yourself and sending it to a lab for testing.
If you consider doing this on your own, be sure to wear protective clothing, gloves, mask or rebreather, eyewear, and anything else. Use caution and coverings to be sure none of the material filters into the rest of the room just in case it does have asbestos, since you don’t want anyone or your pets to be in contact. Afterward, vacuum well with a sweeper that has a HEPA filter and then dispose of the vacuum bag outdoors or clean the bin outdoors to prevent small elements from returning to the room in which you are working. Your best choice is to take a sample of at least two square inches from an inner corner where the drywall panels meet. Be sure to go deep enough into the substrate to be sure you have a good sample.
