The Tool Barn


Preparation

Before you begin the skimming process you need to prepare the surface.  The surface needs to be free of nails and other debris.  In the process of pulling staples or nails the drywall (especially plaster) will likely "pucker" a little bit.  These puckers need to be sanded flush.  If you are working with plaster, sometimes it will flake; you need to break these flakes off and sand the area.  It is always a good idea to scuff-sand the wall and if you are skimming over gloss or semi-gloss you definitely need to sand a bit.  After you have scuffed the wall, make sure you wipe it down so that it is dust-free.  If the area you are skimming was in a bathroom or kitchen you may need to clean the surface to remove grease or dirt.

Starting the Process

The next step is optional but I find it produces better results.  Thin the joint compound a bit.  Use water to thin the compound, don't thin it until it is soupy, it should still be able to hold a "peak".  Also, put down a drop cloth.

Putting the "mud" on the Wall

Using a smaller scraper or tape knife fill the mud pan about halfway.   Take the large knife and put some mud on it.  Hold the knife at a 45 degree angle to the wall and begin spreading the mud on the wall.
