Stop beads are used at junctions of walls, ceilings and surrounds to openings. Trueline supply a wide range of external render beads from 3mm thick coatings. Where an N is shown the render beads can be supplied with a coloured uPVC cover nose to blend in with the render finish. We do recommend the use of our cover nose, on polyester powder coated galvanised beads, in order to prevent scratching of the finish.
