Covering the Rims of Your Window and Door

When you have your necessary ingredients and tools ready, and at your disposal, you need to cover up your windows and door rims with some duct rape. Covering up the edges of your windows and doors will help prevent the drywall from coking in contact with it and making your coating job messy.

Priming Your Wall

When you have covered every necessary area, you need to, first of all, prime your wall. Priming your wall will enable the drywall to stick easily to the wall and make it stay on the wall for a more extended period.

Do not be tempted to start rolling some drywall mud on your freshly primed walls. It would help if you allowed the primed wall to dry to avoid making any mess ultimately. It would help if you let the wall dry for a day or two days, depending on the temperature or season.

Mixing Your Mud

When your wall has dried or when the primer on the wall is dry, you should take out your drywall mud and examine it to know how thick it is going to be. You can pour the drywall mud into an old bucket that you don’t use anymore. When you have poured the drywall mud in the bucket, you can begin to mix it by adding water.

You can use a mixing trough or a mixing drill for this purpose if the drywall mud you are mixing is plenty. The amount of drywall that you will be mixing is dependant on the area that you are trying to coat.

If you notice that the mud you are mixing has not reached the consistency of the or thickness you desire, you can add some more drywall mud. If the mixture is too thick, you can add in water to buff up the difference. 

When you have finished moving your mud, you can pour the drywall mud mixture into a paint pan and paint your wall. It is okay if you do not have a paint pan; you can still use the old bucket you used to mix the mud.

As said earlier, you will need to have a paint roller to be able to skim coat your wall. You can’t fetch the drywall mud and slather it on the wall without using a paint roller. Your work is going to come out messy, and you will end up achieving nothing. 


You should start applying the drywall mud from the top of your well and then work your way down to the wall’s bottom. Do not attempt to do this the other way round hi starting from the bottom to the top.


When you have coated the wall with the drywall mud, you will then go next with your drywall knife. Adjust your drywall knife at an angle and remove the drywall wall mud or the excesses in the wall. A tip to doing this without any problems or hassles is to start from the top and end midway. Wipe off the mud that might be in your drywall knife and then complete skimming the wall with the drywall knife and wipe the drywall knife of the drywall mud again.


It would help if you allowed your wall to dry correctly for about a day or two, and then you can sand the wall of you notice that the surface is rough. Sanding the wall will help you achieve a smooth surface, and this is how to skim coat drywall after wallpaper removal.
