The CT1 FC1 is an acrylic-based filler and caulk that utilises elastomer technology to bond and seal gaps across multiple surfaces. It is designed to work with wood, metal, brick, stone, plaster, concrete, uPVC, and aluminium. The formula provides an ultra-smooth finish without the need for sanding, making it a practical option for preparing skirting boards, architraves, door frames, coving, and window sills before painting or papering.
This product is applied directly to the required gap or joint, where it can fill spaces up to 25mm in a single application. It offers maximum flexibility with an elongation at break of over 100%, which helps to prevent cracking as materials naturally expand or contract. The tack-free time ranges from 15 to 60 minutes, and the caulk cures fully within 2 to 24 hours depending on the environmental conditions and the depth of the fill.
As a solvent-free solution, the FC1 is almost odourless and holds EMICODE EC1 PLUS and A+ Indoor Air Comfort GOLD certifications for very low interior emissions. It maintains superior colour stability over time and is fully compatible with both water-based and solvent-based paints.
