ProDec Advance 4" Mini Roller Sleeves are made from tough, abrasion-resistant nylon with good resistance to solvents. They're designed for applying a range of water-based and solvent-based paints, including gloss, satin, floor paints and many two-pack coatings. The 8mm medium-short pile is suited to smooth and semi-smooth surfaces, while the compact 4" width makes these rollers useful for doors, panels, smaller floors and areas where a full-size roller would be awkward. Supplied in a pack of 10, they're a useful choice for decorators and contractors working with different coatings or carrying out regular maintenance jobs.
