How to Prevent Ghosting

Prevent ghosting on chalk markers

Every chalk artist has experienced it—ghosting. Even if you don’t know what ghosting is, you have probably encountered it at some point. It’s when a faint image remains on a chalkboard’s surface after something is erased ... annoying, isn’t it? But there’s good news! There are a couple of ways to prevent ghosting and it’s pretty simple to do!

Is Your Chalkboard Porous or Non-porous?

Check whether your chalkboard is porous or non-porous. Liquid chalk markers are compatible with non-porous chalkboards only. A porous chalkboard will allow the ink to seep inside its tiny openings (pores), making it difficult to erase. A good example of a non-porous chalkboard is one made of slate or vinyl.

If you’re not sure, ask the seller directly if their product is compatible with liquid chalk markers.  

Do a Spot Test

Always do a spot test before using any type of chalkboard. Here is how to do it:

  1. Write on a small corner of the chalkboard.
  2. Wait for 15 minutes for the ink to fully dry.
  3. Erase with a damp cloth or sponge, or if necessary, a magic eraser, Windex, or our Versachalk Cleaning kit.

Season/Prime Your Chalkboard

Chalkboard priming is an easy way  to create a foundation to prevent ghosting. Here is how to do it.

  1. Take a piece of chalk and rub it on the entire board twice—once using vertical strokes, then again using horizontal strokes. The entire board should be covered with chalk.
  2. Use a soft rag, cloth, or chalkboard brush to wipe the chalk away. Blow off any remaining chalk. The chalk that adheres to the board will serve as a ghost-resistant surface.

My daughter has 4 boys constantly using chslkboard,(home schooler) she eill be happy to know how
to fix this problem with the board. THANK YOU !



Vicky’s right. We did this with our chalkboards in school as well. Thanks for sharing this though. I had forgotten all about this! ?



I’ve had this problem before; I just didn’t know what the real word for it. Thanks so much for this article. I’m looking forward to putting these suggestions!



I’m 65 and chalk boards were our tablets. We learned about seasoning but i don’t think enough people are aware of this technique these days. Even my daughter recently asked why i was doing it. ….she is 30. Thanks for getting that simple helpfull step out there.


This is what we did when our school received a new chalkboard for the classrooms. We kids were given the job and it was considered fun.



So pleased to learn this!
