When you’re plastering corners or any kind of angle, you’ll need to use plastering bead in order to get a clean and professional result. By using beads and bonding plaster, you’ll create corners and edges that are easier to plaster.
What Is Plaster Beading?
Plaster beads are metal strips that help you to create clean and sharp corners and edges. A skim bead is fixed in place with plaster or nails and is suitable when only a skim coat is to be applied. You can secure this type of plaster bead without having to check for straightness so long as the bead is pushed well on to the corner where it’s in use.
An angle bead is suitable when the wall needs both a backing and skim coat. Although this type of bead has a distinctive straight edge, and it’s tempting to think you can achieve a straight line simply by eye, you must use a spirit level and straight edge to check for straightness. Because you plaster up to the edge and then follow it, if the edge is at all out of true, then your angle and your plastering will be too.
This type of bead will also dictate the thickness of the plaster coat, so ensure you have the right type of bead for the job. Because of this flexibility, an angle bead doesn’t need to be attached with the same tightness as a skim bead to allow for sufficient depth for the plaster coat. Simply tack in place or adhere with plaster.
Applying Plaster Beading to an Interior or Exterior Wall
In period properties, it’s not unusual to find wooden beading in place, but for renovation work and in new builds you’ll use beading made from galvanised steel or plastic. Plastic is the right choice for exterior work, as it won’t corrode and spoil the look of the rendering.
You’ll need to pay particular attention to areas like the window reveal that can take a lot of wear and tear.
Cut the beading to length, ensuring that adjoining ends butt up neatly. Nail, screw or tack into place and skim.

If you’re working with plasterboard, always nail the bead in place over a plasterboard join where there’s a wooden batten underneath. Tack nails well in, as protruding nailheads can cause endless problems.
When two beads meet each other, mitre the corners for the neatest and most professional finish.
Pinch the two sides of the bead together so the apex stands a little proud before cutting. Use tin snips to cut towards the internal angle of the beading on both sides, then snap cleanly. You can also use a hacksaw, but be careful not to bend or distort the beading. Always handle the cut ends with care, as they can be sharp.
