When should silicone sealants be replaced?
Silicone: a durable sealant
Silicone joints are found in any bathroom or kitchen. As unremarkable as they appear, they perform an important task. Often, the silicone joint serves as a seal against moisture and humidity so that, for example, water from the shower does not get between the tiles and the wall. This is why you will mainly find silicone for sealing showers, bathtubs and sinks, or as a sealant between the tiles and wall. But don't worry: When installing, for example, a shower tray, the silicone caulk is of course not the only seal. Normally, showers and bathtubs are installed using sealing tapes which provide additional moisture protection for the wall - even if the silicone does eventually start to leak.
What many don't realise is that the silicone joint also functions as an expansion or movement joint. This means that it is responsible for compensating for minor movements such as expansion, compression and tensile stresses between two surfaces. Silicone can withstand a lot more than other grouting materials before it tears or breaks. For example, if the floor and wall are tiled, silicone is applied to the edge where they join, because otherwise the stresses from vibration or the normal settling of the building would cause cracks over time. Silicone's excellent elasticity and good adhesive properties make it the optimal material that can also withstand fluctuations in temperature, movements of the substrate and other stresses. At the same time, silicone also dampens the transmission of sound and vibrations.
Incidentally, expansion joints are normally found at transitions between two rooms, especially when different flooring materials, such as tiles and laminate flooring, meet. Furthermore the silicone joints between a tiled floor and the wall are also considered to be expansion joints. Silicone is also used as an expansion joint when attaching radiators or fittings such as sinks and toilets to a tiled wall.
Brittle, broken silicone joints
As a building material, silicone is very tough and resistant; it can withstand both cold and heat, as well as moisture, without any problems. But over the years, it loses its elasticity and becomes brittle. By the time cracks form in the silicone caulks, they should be renewed, if not before. If the material is cracked, moisture can penetrate and, in the worst case, lead to mould infestation and moisture-related damage.
To prevent such damage, silicone joints should be checked regularly - for example, when cleaning the kitchen or bathroom. This way, cracks can be detected and eliminated at an early stage. It is generally recommended to renew silicone joints every 5 to 8 years at the longest.
