Advantages and Disadvantages of Skim Coat

Skim coating is an important step to give your paint job a sharp and gorgeous look. Avoiding this step may save you some money, but ultimately it may cost you not to have nice-looking walls. However, as the headline suggests, there are some disadvantages too. 

Let’s learn more from this article!

Advantages of Skim Coat

  • The first and foremost advantage of a skim coat is that it is a cost-effective solution to get rid of the old, uneven texture of your walls. There is no need to remove the previous texture before skim coating which leads to saving money and time.
  • Skim coats make the painting process easier. If you apply a skim coat on your walls and ceilings, it will provide you with a smooth surface. This layer helps the painter to paint the walls faster as well as makes the painting process successful by giving a nice, brighter look. 
  • When a smoothest possible surface is needed, the skim coating provides a wall a plaster-like finish if the tape job is unsatisfactory.  If you want to have a Level 5 drywall finish, it is the sole method of getting so.
  • Skim coating gives a wider appearance by blending less between walls and ceiling. This method also visibly makes the ceiling look higher, making your home look even bigger. 
  • Skim coating is strongly suggested if your building contains bright or critical lighting. At critical lighting (when the lights contact the surface of the walls at 15 degrees or less angle) if the wall surface is uneven, it can create an unwanted shadow. 
  • Skim coating also neatens up the seams here between the walls and the molding. A Skim coat is also effective in new drywall, which eliminates any seams or potentially rougher edges between sheets. 
  • Last but not least, it is an easy damage repair process, considering other damage treating techniques.

Disadvantages of Skim Coat 

  • Skim coating is the task of a skilled person. It can be a tremendous mess if someone tries to do it on their own without any prior experience. Furthermore, under the lights, uneven skim coats will be accentuated. After all of your hard effort, this may frustrate you.
  • A Skim coat is not a good option for painted walls. If the underneath paint starts to peel, it will eventually make the surface uneven and the skim coat will be no longer smoother.
  • A skim-coated surface can crack over time if the materials are not in the right proportion or if the coat materials dried out far too rapidly. It also may be the result of temperature change of the surface, using a low-quality material. Whatever the reason is, it can cause trouble in regard to the perfect-looking walls. 
  • When compared to the textured wall approach, the damaged portion of the skim coat wall is much more apparent.
  • As the skim coat dries slowly, it will take extra time to paint. Which will make the process lengthier. 
  • Sometimes it may need various types of material depending on the condition of your wall. So, it’s better to consult a professional to find out a cost-effective solution. 
  • Water does not get along with the skim coating. If your wall surface has any type of moisture or any water leak, it may get bubbles. In this case, you may use a waterproof skim coat, which may cost you a little more than usual. 

A Skim coat is a good reliable option for having a perfect look on the walls. Depending on whether you are going to use a skim coat or not, your walls’ look after painting may significantly vary.


Though it is said that skim coating is a simple easy process, consider doing this task by a professional. A self skim coated wall may not give the look you desired.

However, to obtain a consistent and smooth surface consider applying two layers of skim coat.
