If you want to renovate an old kitchen from the 60s or 70s, you will often come across asbestos-containing floor coverings and adhesives. However, this can also be the case with other floors from this period. Read here whether such a floor can be sealed and what needs to be considered.
In earlier times, asbestos was a popular and very frequently used building material. It is a fibrous mineral that has many beneficial properties. It is

From the 1930s to the early 1980s, asbestos was used on a very large scale. The main danger is the fine fibers that continue to break apart and can be inhaled.
They then remain in the lungs and cause lasting damage. Scar tissue forms, in the long term cancer also forms (the disease is then called asbestosis). In addition, the fibers can also migrate and settle in other body tissues and cause damage there as well. Asbestos has only been banned since 1993, although asbestosis has been known since 1936.
Common in older buildings
There are individual areas in older buildings in which the occurrence of asbestos-containing materials is particularly likely. This includes:
- so-called "floor flex panels" in the kitchen (they themselves contain up to 20% asbestos and are square PVC tiles)
- Glue for Floor Flex floors
- Glue for parquet and wooden paved floors
- Tar cardboard (NO bitumen cardboard!)
- tar-containing primers (tar is also carcinogenic and highly harmful to health)
Rehabilitation of asbestos-contaminated floors
As long as a floor is completely intact, there is no danger. The soil does not then release any fibers. If it is damaged, however, it becomes dangerous. It must then be professionally refurbished.
First of all, an assessment and a test for asbestos must be carried out by an approved specialist company. Only the specialist company decides how the floor is rehabilitated. As a rule, the floor is removed and disposed of in a professional manner. Covering is not permitted in most cases. However, this is always decided by the specialist company, which must also be approved for asbestos removal. For legal reasons, the company alone may then carry out such excess coverage.Tips & Tricks Is there only a risk of asbestos have to You absolutely have to leave the renovation to a specialist company.
