Recommended Use Guide: Cutting and Painting MgO Boards
Magnesium Oxide Boards, also known as MgO boards, are very popular in the construction industry these days. They’ve been around for several years now, but very few people outside the industry know about them or how they’re used.
This is mainly because people have traditionally always preferred drywall as it’s easier to work with. However, MgO boards are just as easy to install, if not more. Moreover, they are more sustainable and also incredibly durable.
Where Can I Use Magnesium Oxide Boards?
Builders for both interiors and exteriors prefer magnesium oxide boards; their excellent water-resistant and fire-resistant properties make them an ideal choice for either. They have a number of applications based on these characteristics.
They are most frequently used for fascia, shaft-liners, wall sheathing, tile-backing, ceiling boards, wall panels, siding, and much more.
What’s the Best Way to Cut MgO Boards?
MgO boards are very easy to cut despite being as strong as stones. Using a thin carbide saw (low speed and circular) would work best. However, angle grinders can be used as well. It’s also possible to simply score and snap using a razor, but it wouldn’t give an immaculate finish.
Once it’s cut, you can get a smoother finish by using carbide tooling to smooth out the edges. But if you want a better and more long-lasting finish, try diamond tooling.
Note: If you’re using an angle grinder with a masonry blade, keep in mind that there will be a lot of dust. However, the dust is completely non-toxic, but you should wear protective equipment nonetheless while doing construction work.
How Do I Paint the MgO Boards?
MgO boards are relatively easy to paint or plaster, making them a treat to work with. All you really need is some standard painting tools, a taping knife, paint, plaster primer, fibre-mesh tape, paint primer, joint finishing knife and your safety gear.
If you want to plaster, start off by applying a coat of plaster primer. Then move on to covering the joints between the MgO boards. Once that’s done, continue with the plaster as you would usually plaster-using regular techniques.
To paint, use a finishing paste to fill and smooth out any joints first; this should prevent any cracks. Next, you need to apply some paint primer. Once that’s done, all you need to do is apply the paint— one coat should be enough.
