Plastering refers to the application of gypsum plaster to a wall or ceiling. It covers the entire surface, smoothing out the irregularities and adding a waterproof layer. When it’s done properly, plastering creates a smooth, seamless surface that’s almost indistinguishable from a professionally-done job but is less expensive, easier to install and more durable.
Contrary to popular belief, plastering is not an alternative to painting. Painting a wall or ceiling is an entirely different process involving covering a surface with one or more thin layers of paint. Painting can also add depth and texture to a surface, which plastering can’t do.
While plastered surfaces are smooth, they’re not as smooth as surfaces coated with paint. Plastering also considerably reduces the amount of light passing through a surface. Of course, you could do this with the help of a professional or on your own.
Today, let’s explore what you can expect during a DIY plastering project. Here’s what you need to know:
Common DIY Plastering Mistakes
While DIY plastering is something you may have the tools and skills to do, it will be all for naught if you make careless mistakes that only result in a lumpy, uneven surface. Plastering is to create a smooth surface and a flat ceiling or wall.
Failing to mix the plaster properly, resulting in lumps
Not finishing the plaster according to the ‘provider’s instructions
Failing to let the plaster dry adequately
Using incorrect plastering tools
Using improper technique
Lacking the skill to apply plasterwork in tight corners
Failing to prepare the area for plasterwork
How to Get Started on Plastering
Preparing the Surface
Preparing the surface is the first step in any plastering project. The surface must be clean and smooth before the plaster can be applied, so you must wash and scrape off any dirt and grime. Then, you can skim the whole surface with a sanding machine. The surface must be even and smooth before moving on to the next step.
Applying the Plaster
There are several different kinds of plaster, and all work differently. All types of plaster come with the same simple instructions, though. You start by mixing the plaster with water, but you have to wait a while before using the mixture otherwise, it will set fast.
The mixture is applied using a plasterboard knife or trowel, smoothing it out as you go to create an even, flat surface. You may not have to use a trowel as wider boards can be fastened down with screws and plasterboard tape.
Spreading and Polishing the Finish Coat
After the base coat has been applied, you have to wait again until the time comes to spread the finish coat. This coat is applied using a large trowel. After this has been done, you have to wait again until the material has been set. You can then sand the surface again, if necessary.
Recognising Plastering Flaws
Finding the right way to do DIY plastering can be challenging. You may have to make a lot of trial and error, but if you want to do it right and not end up with an uneven surface, you need to know how to identify the most common plastering flaws to avoid them.
The Bottom Line
Whether you do it on your own or hire a professional, plastering is something you should know how to do. Plastering is almost always preferable to painting when covering a wall or ceiling. It’s easy to do, cheaper, and you don’t have to be an expert. You’ll have a smooth, seamless and waterproof surface that you’ll be proud to show off when you’re done.
