How to Remove Skim Coat from Walls
Step 1- Safeguard everything from the skim coat.
The primary job is to remove all the furniture and materials that might get damaged from the process. No one wants to whitewash their valuables, do they?
Once you’re done relocating your furniture take out the painter’s tape and make a border along the wall. This will make sure you don’t skim over other parts of the room and make a total mess.
Step 2- Apply a base primer.
The second step is to put on some primer. The reason behind this is that the wallpaper might start to get loose at some point.
The uneven finishing will look terrible if it isn’t smoothened out. So, take out your rolling brush and apply a layer of primer to get a flat wall to skim over.
Step 3- Prepare a thin joint compound.
The next item on the to-do list is to prepare the coating. To do this, take an appropriate amount of joint compound and mix it with water.
Then take a mixing rod to grind the elements together. Once you reach creamy consistency, stop mixing.
If your mixture doesn’t have lumps, you’re good to get on with the next step. In case your mixture has some lumps don’t panic.
Simply keep on blending the mixture to have a pancake-like consistency.
Step 4- Apply the skim coat.
For this step, all you have to do is take out your paint roller and dip it in the bucket of the mixture.
Then you can start doing the fun part. That is, roll the paint roller over your wallpaper. But make sure you start from the edge and slowly make your way to the center.
While applying the best roller for skim coating make sure you do it in thin layers. This way, your wall will look smooth and perfect.
Step 5- Smooth out the skim coat.
The fifth step is to use a trowel to smooth out the layer. This will ensure that you get the professional finishing that you want.
To save some time you can get someone to help you with the process. The other person can roll the mixture while you smooth it out with a trowel.
Step 6- Sand to even out the layer
For this step, all you have to do is use a sander and even out the bumps on the wall. This is a very easy step and once you’re done you’ll be awarded a clean wall.
Step 7- Wait for the layer to dry.
Once the skim coat is smoothened out, you need to sit back and relax. This is because the layer of mud needs to dry out first.
So, have some juice while the air does its magic.
Once the coating layer starts looking like chalk you can commence the next step.
Step 8- Repeat the process.
The sad part is that one layer of skim coating is not enough to cover your wallpaper. So, you have to repeat the entire process until the wall has no trace of wallpaper.
Once you’re done you can put down the skim coat drywall with a paint roller and get some rest. You finally have a clear wall with no trace of the old wallpaper.
