Plastering the Internal Walls

  • Mix the Plaster

Plasters from different manufacturers have slightly different mixing procedures. So, it’s best practice to have a good look at the instructions before throwing everything in the bucket. While mixing, make sure to always add the plaster to the water instead of doing the opposite. Use the pedal accessory and the power drill to efficiently mix the plaster and get a lump-free nice creamy consistency. Furthermore, make sure to only mix small amounts of plaster at a time as the plaster will start drying as soon as you mix it up.

  • Apply the First Coat of Plaster

To achieve a smooth and level outcome, it’s preferable to apply two coats of plaster. Scrape a trowel full of plaster mix out of the bucket and plop it onto your hawk. Now collect some of it from your hawk using the trowel and use smooth strokes to make the plaster stick to the wall. Meanwhile, press the plaster mix onto the wall and try to distribute it evenly.

Make sure to use the full force of your body to firmly apply the plaster to the wall. Don’t worry, the suction effect won’t let the plaster slide, allowing it sufficient time to dry and stick permanently. Do the same repeatedly to cover the entire wall with plaster.

After you’re done with the first coat, allow the plaster to dry for a while. Open the windows and turn on the ceiling fans to speed up the drying process. Be patient and don’t start applying the second coat instantly after applying the first coat, doing so will remove the first coat of plaster as the cohesive force between plaster molecules is remarkably weak while it’s wet.

This will render all your hard work meaningless. While the plaster dries, make sure to clean the tools and buckets and prepare them for the second round.

  • Apply the Second Coat of Plaster

The second and final coat of plaster will demand absolute perfection, there is no room for error. Achieving a smooth and lump-free final finish is crucial to make the paint look good once it’s applied. That being said, before going all in, fix any lumps or holes that might’ve gone unnoticed while applying the first coat. Also, make sure to clean around the edges of your wall with a good-quality wet paintbrush. Going from the bottom to the top, repeat the same process of plastering, this time with extra care and attention. Use long sweeping movements to achieve a smooth and plain surface.

After you’re done, take a coffee break and let the plaster dry for about half an hour, you can follow the same methods to speed up the drying process. Make sure not to let the plaster dry completely. Furthermore, if the weather in your area is too hot, make sure to gently flick some water onto the wall to prevent unwanted cracks in the plaster.

  • Polishing

While the plaster is still considerably wet, it’s time to add the final touches and achieve the desired smoothness. To do that, flick some water onto the wall using the paintbrush and use a clean and wet trowel to level out the surface even further. Remember the wall is still delicate so refrain from applying too much force this time.

Gently polishing the plaster will fix all the unnoticed issues. That’s it, you’ve successfully plastered the internal walls of your home. All you need to do now is wait, let the wall dry for a full day or more and apply paint afterward.
