Manufactured from polyurethane these drain covers has a naturally sticky finish on one side which provides a mechanical grip and helps it to adhere to the surface it is being used on. Carry handles are built-in to aid deployment and recovery. After use it is advisable to remove any particles that may have adhered to it. (A mild soap solution is recommended – don’t wipe down with a cloth as fibres will stick to it) When selecting a cover always try and choose a size that gives you a minimum of 100mm overlap to help ensure a positive seal.
