Hey bmyers2497,


Thanks for your question and welcome to the community!


Skim coating, or applying sheet rock mud, to the wall can be done fairly easily.


It all depends on how much you'll need to apply first. For starters, repairing any holes or loose areas of the drywall first to ensure whatever mud that is applied over it will stay properly. Any large holes than are larger than a door knob need to be patched first to ensure the skim coat will work.

Step 3: Cover the patch with joint compound and allow it to dry


Once this is done, you'll need a few supplies as shown below to get patching your walls once and for all. Depending on how much needs to be applied will determine how much materials you'll need. For example, we carry sheetrock mud, or joint compound, in small quart sizes up to several gallons in a container.

Once you have a level and clean surface, you can now apply the joint compound with your putty knife for small areas, for large areas, use the wider taping knife.


Use a liberal amount of joint compound but smooth it level with the knife of your choice as soon as it is applied.  Allow the mud to dry completely before sanding it down. You may have to do multiple passes, but this the absolute best way to work in thin layers rather than one thick messy layer.


After sanding down the new joint compound, you can then inspect any nail holes or uneven areas for more application. Using a direct light helps, like a worklight, to ensure all areas are level.


Once all the skim coat is finished, you can then clean the surface with a moist rag and then prime your walls. This is just as important as what you just did, since a good primer can seal the new drywall and prevent it from 'flashing' or bleeding through the wall.


Using an oil based or shellac primer is good for this, and afterwards you can place any top coat of your choice, latex based included.


Let me know if you have any addtional questions,
