Old joints in the bathroom and in the kitchen are not only ugly, they also can be really dangerous for your health. If water enterss through the leaky joints behind the shower tray or disfigures the sealing joints in the kitchen mold, can have expensive and sometimes harmful healthy consequences.
Joint width: Apply joint sealants properly
Joint width is slightly larger than the gap width to be filled.
In most cases, should be sufficient two and a half times the gap between the tiles. With a gap of 5 mm, has to be 12,5 mm.
Outside, or other thermally highly stressed environments, it has to be more… Here at 5 mm, the distance of 20 mm would be sufficient. This is sufficient to compensate thermal deformations and seal the joint permanently.
Silicone Sealants – Elastic sealing
Today silicone joint sealants has to have a lot better qualty then before. The combination of good processing properties and sealing quality it must be permanently elastic, so that they can absorb vibrations without the joint breaks. Often we can old gaps that breaks and at this places water gets into the wall or behind the kitchen or bathroom installation. You can prevent this by waiting a period to apply the silicon and that Silicone Sealants are used with a particularly high elasticity.
Critical enviroments such as terraces, balconies or bathrooms needs sealings with high movement capability. In addition to good processing and sealing properties must be permanently elastic. Here Silicone Sealants are used with a particularly high elasticity.
