Knowing how to plaster a corner is an important aspect of drywall installation.
There isn’t much scientific theory behind it, but there are a few factors you should consider to achieve a sparkling finish.
The old-fashioned technique might work, but the method we’ll show you is 10 times quicker and you can master the art of plaster beading with this simple guide!
What’s better than that? It’s really simple for novices! All you have to do is know what you’re doing.
How to Plaster a Corner With Plasterboard
This is by far the easiest background to stick corner beads onto, and one secret weapon makes it effortless.
I’ve seen few plasterers use this equipment, but I assure you that it’s simple.
A heavy-duty staple gun is a tool I use. Fire your staples into the slots beside the wings of your bead as soon as you see them.
It’s simple since most guns have two guide marks to assist you with your aim.
I find this to be the most efficient approach to installing your corner beads. To be honest, any stapler will do, but the Stanley and Arrow ones are especially effective.
If you prefer another option, Ring Shank nails are a good alternative.
They’re far easier to use than clout nails and always get a secure grip on the timber behind the panel.
This is a highly successful technique for fitting corner plaster beads, but I find the staple gun to be more efficient.
Plastering Onto an Existing Corner
Many individuals propose using cut nails for this, but what I’m going to say is that it’s highly unlikely to be the greatest approach!
Fixing beads with nails has been my biggest issue when plastering a corner.
It is difficult to get a good grip (particularly with clout nails), it may damage the plaster underneath, and it is unreliable.
Your bead is frequently hanging off after you’ve used clout nails, and the plaster has been blown away as a result of the harm.
I’ve found that the best approach to do this is by plastering the beads. It takes a little longer, but it delivers the most effective results. Here’s how to do it:
- Use a combination of multi-finish plaster to add interest.
- Apply the plaster to the area where your old wall meets the new one.
- Thick blobs are required so that the bead has something to adhere to.
- If you’re using a primed mould, place your bead in the right location and push it into the plaster.
- Clean any excess off your skim bead and leave it to dry for at least 30 minutes before beginning.
Fixing Corner Beads Onto Brick
This technique, in contrast to the previous one, is more complex and falls into the category of rendering/floating. It’s a new form of art, but here’s a short explanation.
Fixing corner beads with plaster is similar to beading on existing walls in that you use a floating bead.
The distinction is that instead of fixing your top bead with plaster, you need to fix your corner bead with plaster.
This is another skim bead that’s closer to the skimmer. It has matted wings and adds greater depth for rendering.
These are usually used with sand cement or bonding, depending on your render technique.
