The Hamilton Perfection 4' Extra Long Pile Midi Roller Sleeve is made from a hard-wearing polyamide mix, designed for a fast and even finish on rough and extra rough surfaces, with the added benefit of superb paint pick-up. The roller sleeve fabric is thermobonded to the core to prevent any unwinding, even when soaked in water or solvent. It is suitable for use with emulsion, solvent-based and water-based masonry paints.
