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 various 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 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. A choice of colours is available to get the best match for the job.
