Silicone Sealant Bath (90ml) is a specialized "handy-tube" version of sanitary silicone, specifically formulated for high-moisture environments. The 90ml size is perfect for small repairs—like sealing a single basin or patching a leak in a shower—where a full 260ml contractor cartridge would be wasteful.
In Heidelberg, this is most commonly found under the Glue Devil or Bostik brands.
1. Key Features
- Anti-Fungal & Mildew Resistant: Contains powerful fungicides to prevent the "black mold" that typically grows in damp bathroom corners.
- 100% Waterproof: Forms a permanent, watertight seal that won't degrade with constant exposure to hot water and steam.
- No Caulking Gun Required: The 90ml tube is "squeeze-ready," meaning you apply it directly by hand, which is much easier for tight spaces or DIY beginners.
- Superior Adhesion: Specifically designed to bond to non-porous surfaces like ceramic tiles, porcelain, glass, and acrylic tubs.
