Before heading to smooth plaster walls before painting, let us first prepare the room ready for painting.

Here are my quick tips to prepare the room for painting.
  • Clean the room, clean all the dust and debris. Use a vacuum cleaner if needed.
  • Wear safety goggles and gloves.
  • The scrape of any paint flakes from the wall.
  • Make sure all the needful items from paint colours, paint brushes and tools are kept ready. Apply a good quality primer to the walls.

Once done with basic steps, let us waste no time and jump on to our main question today. 

Firstly we need to smoothen the rough walls with this below method and then we shall proceed with our method no.1 to smooth plaster walls before painting.

Bye-bye rough walls

Plasters make the walls dry, and that has to be smoothened down before you start painting them. An incredible way to do that is skim coating. Skim coating is applying a solution to the rough walls. In this process, you apply a thin layer of mud using a squilgee knife. The mud used to apply over the plaster is also known as a joint compound. The benefits of skim coating are as follow:
  • Easy to apply
  • Produces quick and great results
  • Repairs all cracks
  • It fills up any holes in the wall
  • Levels to uneven areas in the wall

Unfortunately, not all are aware of how to skim coat the plaster walls to smooth it out. Before we learn how to, run to the nearest shop to purchase the given list of things you will need before skim coating:
  • Drywall sander
  • Joint compound
  • Putty knife
  • Wallbound knife
  • Sandpaper
  • Mud pan
  • Safety goggles 
  • Gloves
  • Safety face mask

Here are some simple five steps to smooth plaster walls before painting. Make sure that you follow it step by step to get the perfect results. 

Step 1
Clean the wall surface with a prime sealer, degreaser and sanding block. You can also opt for an orbital or a drywall sander for quick ways to sand the wall.

Step 2
Mix the joint compound with water and mud according to your requirements. Mix it properly. Leave no lumps in the mixture. Ensure the consistency of the mix. Neither too thick nor too loose. 

Step 3
Now it’s time to apply the mud to the walls. Start from the corners and not the middle area of the wall. Don’t be too slow in this process, as the mixture will dry up fast once applied. 

Tip: Hold the squilgee knife at a 30° angle and continue applying the coat from top to bottom.

Step 4
Time for the final coating. Always go for double coating for super results. And if you are still discontented with the results, go for 3-4 coats with no qualms. 
Remember to apply the 2nd coat only after the first coat dries completely. Then, let the coat dry nicely for 2-3 hours.

Step 5
Follow this only if needed. Check the wall if it is dry or not. Check for any imperfections or any bumps on the wall. You can sand it down if you feel any corrections.  

Once done, clean the whole area, the wall and the floor. 

So what do you think? Wasn’t this a super easy method to smooth the plaster walls before painting? Before you start painting the walls, make sure to prepare your wall correctly to get excellent results.
