Selecting the right chalk art mediums for your project can be a difficult decision. Finding a quality product with the right surface is important. Because of the variety of chalk art mediums, it is important to determine if the substrate you are using is porous or nonporous.

Choose from nine sizes and five color combinations of the country craft framed chalkboards and chalk art mediums. Sizes offered are 8x10, 9x12, 11x14, 16x20, 18x24, 20x24, 22x28, 24x30, and 24x36. Colors include black, blue, green, red, and cherry. Contact us if you unable to find your desired style.

Porous Versus Nonporous

Porous surfaces allow the passing through of water, liquid, or vapor. Pigment from the markers could get absorbed when using porous chalkboards. These types of surfaces include chalkboard painted surfaces, wood, paper, and cardboard.

Nonporous surfaces will not absorb water and liquids. Nonporous surfaces like chalkboard labels, mirrors, glass, glazed ceramic, slate, metals, laminates, and some plastics, will result in liquid chalk being easier to remove.

Therefore, always test your liquid chalk markers on a small portion of your medium to see if they are right for your project.
