A silicone sealant is usually ran along the return or back edge of the stop bead to prevent water ingress. These can be up against window and door frames, soffits, copings, other claddings or building fabrics. Stop beads, also known as stop end beads, create a square-finished edge for external render systems. The ‘nose’ of an angle bead creates straight and crisp lines in the render finish, which is why ProBead uses high quality PVCu that does not warp, and our angle bead is supplied boxed to prevent bending or twisting in transit. Angle beads eliminate the need to manually form corners on site, and can act as a guide to the depth when applying the render. Using a bellcast bead in the correct place prevents damp getting into the render and can stop render cracking.Īngle beads, also known as corner beads or quoin beads, are used on corners and returns of external rendered elevations and apertures.Īngle beads reinforce the render system at the corners and returns, helping to reduce impact damage and keeping the render edges sharp. It is important to use the bellcast bead and not a stop bead, as the angle it creates stops water running back towards the wall underneath the bead. Bellcast Bead or Drip Beadīellcast beads, also known as drip beads or bell stop beads, create an angled lip at the base of a rendered wall and above windows or apertures.īell cast beads allows any water running down the face of the render to drip straight off. Let’s look at how to choose the right render beads and detailing for a long-lasting rendered façade. Plastic render beads will not rust or bleed, and are as durable as the render. They are through coloured bead, matched to our render colours that can be easily cut.

There are 34 different ProBead profiles and a huge range of colours– so how do you choose the right render bead? ProBead are PVC render beads, make in the UK from recycled plastic.

Render beads form and protect the edges and corners of external render, so it is important that it is as durable and looks as good as the render itself. Using the correct type of render beads for a rendered façade will ensure the best finished look, ensure durability and help protect the render from water damage, staining and cracking. The beading or trim used in an external render system might be more important than you think.
