What is the Purpose of Skim Coating?
Skim Coating over paint is a simple process. It is not something that requires arcane skills. Its main purpose is to substitute paint over parts of a wall that shows cracks and wear.

Skim Coating vs. Drywall coating
Both the processes are almost the same. While going for the long term, you should consider using the drywall coating method; we would still advise you to do skim coating. Skim coating, which uses prime sealer-type compounds, is white perfect remedy for a fast wall crack repair that does not require any paintings.
Drywall coatings use drywall mud compounds, which might last longer, but requires a coat of paint later on since the end product is mismatched unattractive stripes of mud color on the wall. While with skim coating, painting is optional; such is not the case for drywall coating. Hence, even the time taken for drywall coating exceeds that of skim coating. If you are looking for a quick remedy, the skim coating is the best choice.
Cost and Time
Net Cost: 50+ USD
Time required: 3 to 4 days
The cost of skimming isn’t much, and anybody can afford it. The cost of hiring someone exceeds that of doing the work on your own while learning from scratch. While skimming is indeed an easy process, it requires a long time to be completed. Of course, the time also depends on the size of the wall or room and the surface area you are covering.
If it is a big room of 100 meters square, it will take about 5-6 days. If you are skim coating a single wall, 2 days would be more than enough.
The tools we will be working with are mentioned below. However, you can consider many other alternatives for this equipment. For instance, instead of a sponge, you can also use hoses. Also, sanders other than the hand sander are appreciated.

- Primer Sealer
- Hand Sander
Should You Prime Before Skim Coating?
The answer is a little bit complicated, but the end result is worth it. Priming will improve the adhesion of the finish and reduce the amount of sanding that’s necessary. This will save you time and sanding later on. As for the type of primer to use, that’s up to you.
Some people choose to use a traditional primer while others go with a skim coat primer. However, applying skim coat as described in your paint manufacturer’s instructions – usually between 400-600 grit sandpaper – is usually recommended. If you choose not to prime, be sure to clean and roughen up the surface beforehand.
