FC1 Filler & Caulk is a multi-purpose filling and sealing compound designed for interior finishing, maintenance and repair work. It provides a flexible, paintable finish that is suitable for sealing joints, filling cracks and tidying gaps across a wide range of common building materials.
This filler and caulk is well suited to home improvement and maintenance tasks including cosmetic repairs, gap filling and joint sealing prior to painting or decorating. It can also be used for light renovation work and finishing touches on new installations.
For best results, surfaces should be clean, dry and free from dust or grease before application. Apply in a consistent bead, smooth if required and allow to cure fully before painting.
