No, chalkboards are a porous material.
Yes, we generally consider stainless steel to be a nonporous surface.
Water dries quickly on a chalkboard due to the porous and absorbent nature of the chalkboard surface, which allows the water to evaporate rapidly. Additionally, the rough texture of the chalkboard may prevent water from pooling or clinging to the surface.
A chalkboard has matte surface, which is non-reflective and not shiny.
To prime a chalkboard for optimal use and longevity, first, clean the surface with a damp cloth. Then, rub the entire surface with chalk and erase it. This helps to create a smooth and even surface for writing. Repeat this process a few times before using the chalkboard regularly. This will help prevent ghosting and ensure the chalkboard lasts longer.
A chalkboard typically has a thin layer of iron beneath the surface. This iron layer allows the magnet to stick to the chalkboard. The magnetic force between the magnet and the iron in the chalkboard is what causes them to attract and stick together.
For long-lasting durability and a smooth writing surface, the best chalkboard material to use is porcelain enamel.
The best material for a chalkboard is usually a smooth, non-porous surface like porcelain or enamel. These materials provide a durable and easy-to-clean surface for writing with chalk.
Chalkboards are typically made using a smooth, hard surface material such as slate or a specially coated wood panel. The surface is then treated with a layer of chalkboard paint to create a writable surface for chalk.
If finished properly chalkboard paint would work just as a regular chalkboard would. Depending on the wall type you may need to sand the paint after every layer dries to create a smooth chalkboard-like surface on a wall.
the disadvantges are they are very expensive and the surface of the whiteboard can easily be stained
