When it comes to high-performance adhesives and sealants, CT1 has long been the go-to solution for professionals who demand reliability, strength, and versatility. Now, from the same trusted creators comes BT1 – a game-changing product specially formulated for use in bathrooms and wet environments.

What Is BT1?

BT1 is a unique sealant and adhesive designed specifically for sanitary applications. Developed using Tribrid® Technology – the same advanced formula that made CT1 a household name – BT1 delivers exceptional performance in high-moisture areas. Whether you're sealing around a bath, fitting a shower tray, or installing tiles, BT1 offers unmatched adhesion and mould resistance.

Why Choose BT1 Over Traditional Silicone?

While silicone has traditionally been used in bathroom applications, it comes with well-known drawbacks: poor adhesion to certain surfaces, tendency to mould, and difficulty in reapplying or cleaning. BT1 tackles all these issues head-on:

  • Anti-fungal & Anti-bacterial: BT1 contains advanced technology that actively resists mould and bacterial growth, making it far more hygienic than standard silicone-based products.

  • Strong, Long-Lasting Bond: With superb initial grab and lasting adhesion, BT1 ensures your fixtures stay firmly in place.

  • Solvent-Free & Eco-Friendly: It’s safe to use in enclosed environments and contributes to better indoor air quality.

  • Paintable & UV Resistant: Unlike traditional silicones, BT1 can be painted over and stands up to sunlight without degrading.
