What Is A Drywall Skimming Blade

A skimming blade is a must if you want a flawless finishing coat on your drywall.

These tools smooth drywall compound on walls and ceilings to reduce the number of lap marks and leave a professional finish. You can use skimming blades on other types of compound too, like plaster, for example.

They also come in handy for butt joints.

When Should I Use a Skimming Blade?

You should use a skimming blade to add a skim coat to a wall. A skim coat consists of diluted joint compound that’s smoothed on the wall or ceiling to acquire a level-5 finish. (Level-5 is the premium finish of drywall.)

Here are some examples of when you might need to skim coat a wall:

  • You’ve recently installed drywall and want a level-5 finish.
  • You need to repair the wall after removing the old wallpaper.
  • You’ve patched drywall, and the rest of your drywall already has a skim coat on it.
  • You’d like to make your old walls look nicer.

While skim coating is not the default for drywall finishing, it is the highest quality finish possible. And if you want to achieve it, a skimming blade is a great tool to have on hand.

Another reason to use a skimming blade is to reduce lap marks on your joints. For example, after taping and mudding your joints, you can use a skim blade instead of a drywall knife to smooth the mud.
