When formulating this internal silicone sealant, we used our experience and know how to find the 'happy medium' for a product that guns out with good body (eg. it's not too runny) but also not too stiff. The many different HM products in the marketplace vary greatly when it comes to the consistency of the wet material and, although it's largely down to personal preference, we carried out extensive market research to discover the sweet spot for perfect application (gunning out) and finishing (tooling off) and 3C HM was what we settled on. Judging by the sales feedback, we reckon we got it just right!

3C Refill Sanitary Sealant is ideal for and applications internally where high humidity is present such as sealing sanitary ware and other joints in domestic, commercial and industrial settings. 3C Refill Sanitary cures to a highly elastic rubber seal that won't shrink or crack with expansion and exhibits fantastic adhesion to various non-porous substrates such as aluminium, ceramic, glas
and wood (bare & painted).

This is a tough question to answer outright, as there's many variables that determine the longevity of the final cured sealant. Providing the surfaces were clean, dry and free from dust & dirt etc. and a good adhesion was achieved, then the 2 x most important factors to help keep 3C Refill Sanitary Sealant looking fresh and mould-free is to make sure you clean your substrate after use and perhaps even more importantly that you have adequate ventilation in the room. In general, a premium quality sanitary silicone sealant such as 3C Refill Sanitary should last anywhere from to 10-20 x years with proper care and attention.
