How to seal internal joints using silicone sealants?

Joint sealing creates a waterproof seal to intercept movement within the surfaces or at the point of intersection between various building elements. Joint sealants are used for several purposes including: – to close open joints to keep water and air out (both exterior and interior) for appearance and cleanability (in interior surfaces where water resistance is not an issue) and to reduce sound transmission through cracks (usually interior and internal to composite assemblies). Silicone sealant is a great way to fill in gaps between tiles, shower screens, baths and sinks. It also stops water seeping in where you don’t want it.
