Plastering may seem like the best solution when you need to smooth out your walls, but it isn’t the quickest route to take.

When it comes to the walls of your home, whether they have been freshly plastered or it’s been some time since they were last fixed up, we always seem to want the quickest and easiest way of completing our task.

For freshly plastered walls, you’re in luck. Fixing up a wall that is only in the plastering stage requires much less effort and time than trying to sort out a wall that has been damaged.

New plaster

Having finished covering the room in a fresh coat of plaster and waited the appropriate amount of time for said plaster to dry, it’s time to look for imperfections.

You should never immediately paint over plaster. Plaster is rarely smooth from the get-go, and you could have all sorts of bumps, rough patches, and cracks decorating your wall after it has been plastered for the first time.

These issues are completely normal. It’d be a bit of a stretch to expect a homeowner to have perfectly smooth walls after plastering. Even professionals find it difficult, and you’ll often see them patching walls up and sanding away to make the surface as perfect as possible.

Fill the holes first

There’s no point in sanding anything down until the holes and cracks in the wall have been filled with more plaster. Pack the plaster into these crevices, smooth out the surface, and wait for it to dry before doing anything else.

The reason for this is simple. If you were to sand down and clean up a wall after waiting for the plaster to dry, only to then discover a hole or crack that needs to be filled, you’re more than likely going to have more sanding to do later.

Sanding time

After the wall is slathered in plaster and that plaster is dry, you can grab an electric sander and level out any weird rough patches or bumps. Focus on the areas around cracks or holes that you’ve filled in.

After this, you can continue by cleaning everything up, adding the skim coat, and then painting.

How to smooth without plaster

You don’t always need more plaster to smooth out your walls. One of the main parts of plastering requires the individual to sand everything down.

When you’ve discovered any imperfections that are protruding out from the smoothness of the wall, a sander is your best friend and can solve all of your problems. 

Fixing small imperfections

Rather than breaking out the plaster for tiny holes and cracks, use a fine surface filler.

This product was created to fill in surface imperfections and is perfect for dents or similar blemishes that you’ve found in your plastering job.
