The 4 important uses of Interior caulking

Interior caulking is used to seal the interior joints of a building or between surfaces within a building. It is used for the following purposes:

  1. Between surfaces- To prevent water leaks that can result in the growth of mould.
  2. To seal interior joints between panels in laboratories or food processing facilities.
  3. To seal openings in fire resistance walls and floors against the spread of fire (fire stopping sealants).
  4. To enhance the appearance of a space or room.

Mould and Indoor caulking

Interior caulking joints guard the structure against indoor water leaks and moisture between surfaces. If water finds its way behind or between 2 surfaces (For example kitchen counter and a wall, between tiles, bathroom counters), mould can grow and spread, especially if the moisture problem doesn’t seem to be corrected.

Problems associated with mould

The biggest problem with mould is its variety of health effects and symptoms as well as an allergic reaction. The application of Indoor caulking protects surfaces against water seepage and thus helps to stop the expansion of mould. 

Mould-free indoor environment 

By ensuring a mould-free indoor environment, businesses and property owners protect the health of their tenants or employees.

Employers are required to ensure the health and safety of their employees at the workplace. This includes protecting workers from mould in workplace buildings.

Mould effects on Building materials

The growth of indoor mould should be avoided because mould can start eating away materials (For example Wood-based materials are highly susceptible to mould). Mould can affect the looks, smell, and even the structural integrity of a building. Moulds can grow on any surface as long as moisture or water and oxygen are present, however, mould growth can be prevented by controlling moisture.

What is Firestopping caulking?

Firestopping caulking is a sealant that delays or prevents the spread of fire and smoke within a building through small penetrations and openings and contributes to protecting and saving lives. Fire mastic sealants are installed in the penetrations and openings of fire resistance walls and floors and are rated according to the amount of time they can hold backfire (usually between 1-4 hours.)
