Generally, asbestos siding will not pose any danger if it’s left alone and remains in good condition since it consists of non-friable asbestos. This type of asbestos won’t give off toxic substance unless it is damaged, sawed or drilled. So, if you are living in one of the older homes its best not to tamper with the siding if it is in a good condition. However, if the siding starts to deteriorate due to aging, weather or heat, then you must repair it. Can you paint asbestos siding? Yes, it’s not only possible for you do this, but it is actually recommended. Read on to find out more…

Asbestos siding had been used extensively in the homes and buildings that were built between the 1930s and 1980s, but its exposure was linked to some severe illness like lung cancer and Mesothelioma. As a result, the use of this material was banned. Initially, it was used in buildings because it has excellent properties for fire resistant. In addition, when this substance was combined with siding and flooring materials it increases durability and strength, whilst providing the structure with fireproofing and insulation.

Most of the older houses still contain fireplaces, insulation, siding, flooring and other materials with some amount of asbestos content. In cases where the fibers are entrenched or encapsulated, building materials like asbestos vinyl floor tiles or siding will be pose little health risk. These products will only pose a health risk when the fibers are released in the air or become friable or loose.

Many cases have been reported for severe health conditions and deaths in commercial and industrial situations, as opposed to residential situations with less evidence of illness. However, you must always take care when working close to or handling asbestos containing materials. This means that you should wear protective breathing devices, goggles and clothing to prevent the inhaling of fibers if you are planning to paint asbestos siding.

There are different kinds of asbestos siding: shingles; asphalt roofing; wooden shake vapor retardants and cement siding.
The main reason for painting is to prevent deterioration, because this will cause the fibers from asbestos to become friable and contaminate the air outside. When it comes to building materials, particularly for the exterior, it is important to do the preparation before applying the finishing coating. So, proper cleaning must be done prior to painting asbestos siding. Besides that, it’s best to get help from a paint supplier to ensure that the primer is compatible to the finishing paint.

Always remember to cover or seal the asbestos siding to prevent it from releasing dangerous fibers. You can use top quality latex paint on the siding to seal it, as this will bind the fibers and stop their release. On the other hand, you can cover up by placing a regular siding or insulation boards on top. Bear in mind that these repairs must only be carried out by a professional.
