Decorators caulk is a soft and flexible substance used to fill gaps or repair cracks, leaving a clean and smooth finish ahead of a decorating job. It can be used on a variety of materials in or around the home, and is waterproof and solvent free - making it easy to apply via a gun for internal or external tasks. It provides a tough, elastic rubber seal for a long-term hold and is mould resistant, increasing its durability. Decorators caulk can be painted over after just one hour with no sanding required, saving valuable time on renovation projects. There is a choice of colours available to get the best match for the job.
