The Hamilton Perfection 4' Medium Pile Midi Roller Sleeve is a microfibre blend roller sleeve, designed for a smoother finish on smooth and semi-smooth surfaces, with the added benefits of excellent paint pick-up and coverage. 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 eggshell paints.
