Erasable Liquid Chalk Marker for Boards – Doricolor

What is an erasable chalk marker?

The erasable chalk marker is an innovative substitute for chalk. It differs from chalk primarily in that its ink is more opaque. They were created for writing, drawing, and painting on chalkboards.

What is liquid chalk?

It is a paint that mimics the texture, grain, appearance, and color of real chalk strokes. The invention of this ink facilitated the development of liquid chalk markers.Before its invention, the only option for writing on dark chalkboards was conventional chalk (made of calcium carbonate). When drawing with chalk, it releases some dust, which can cause respiratory difficulties for people with allergies. Liquid chalk markers do not have this problem. They are formulated with water-based inks. Such inks are more opaque and dense than those found on the market. They are almost never toxic, as most manufacturers avoid harmful chemicals like toluene or xylene. They also do not use alcohol as a solvent.

How do erasable chalk markers work?

Due to the high density of their ink, markers often have a pumping system in the barrel. This usually consists of a flexible plastic plunger, such as polyethylene, which pushes the ink towards the tip by pressure. Before using it, it should be shaken vigorously. Immediately afterwards, the plunger is pressed several times, assuming it has one. At that point, the marker will be ready to paint. To erase liquid chalk writings and drawings, a damp cloth or rag is preferably used. It can be difficult to erase the mark with a dry eraser or chamois depending on the marker model because these markers leave a thicker layer of paint on the board. Finally, liquid chalk markers can be used on any surface. Their mark will be indelible on porous surfaces such as paper, cardboard, cardstock, or wood.https://youtu.be/EP09D_SB10A
