C-Tec FC1 Unique All-In-One Filler Caulk – 310ml

FC1 is the ultimate all-in-one filler and caulk, developed specifically for professional users who need reliability, flexibility and a high-quality finish. This premium acrylic-based formulation uses advanced elastomer technology, combining carefully selected fillers with high-performance acrylic polymers to deliver outstanding results across a wide range of applications. Designed to both fill and seal, FC1 bonds effectively to materials including wood, metal, brick, stone, plaster and many plastics, making it a versatile solution for finishing work, repairs and detailing.

Professional Finish with Minimal Effort

FC1 is engineered to deliver an ultra-smooth finish straight from the gun, eliminating the need for sanding once cured. Its advanced formulation allows gaps of up to 25mm to be filled in a single application, saving time on site and reducing the need for repeat work. The acrylic base provides maximum flexibility, allowing the product to accommodate movement without cracking or shrinking, while maintaining excellent colour stability over time.

Flexible, Safe Built to Last

FC1 contains no solvents, making it safer and easier to use in both residential and commercial environments. Once applied, it cures to a durable, flexible finish that resists cracking and maintains a clean, professional appearance long after installation. Whether you’re sealing joints, filling gaps or completing final finishing touches, FC1 delivers consistent, high-quality results every time.
