The Hamilton Perfection 4' Short Pile Midi Roller Sleeve is made from high-density microfibre, designed for a fine finish on smooth surfaces, with the added benefits of excellent paint pick-up and coverage. The roller 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 primers, undercoat and eggshell paints.
