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.

Using Cohas Eco chalkboards, our artists were able to create farm market images of strawberries, apples, and pears with the waterproof 6mm markers.  Our artists also used the Zig Illumigraph markers, which are highly fluorescent and suitable for lighted signs.  These markers work with a black light and glow when light reflects or passes through them.

DIY Christmas Ornaments using Zig Posterman Waterproof Markers

Our artists at are always trying to use the Cohas Color Collection for fun projects.  The latest project involved drawing on clear plastic ornaments with the 1mm waterproof metallic gold and white markers. The flecks in the metallic paint sparkled in the lights of the tree and are nice and opaque.

Additionally, one of our artists used a metallic marker and painted on one side of a piece of acrylic glass.  The result is a colorful shiny background that can be easily cleaned with Windex.  Artists can also use spray paint to complete the same effect on the back, but that would create a more permanent background on your mediumPaint markers used on clear plastic to create a wedding favor.

Spring has sprung and that means it is time for barbecues! Here in this video, John Neal the sign writer creates a chalkboard for Aubrey Allen Butcher’s using markers and paint.  The Zig Posterman Chalkboard Art will bring customers in much more than a machine printed poster on a sandwich board.  While customers may be interested in the tasty BBQ offered by Aubrey Allen the Butcher, they will also stop and admire unique chalkboard art more often than you may think.

Starting the Zig Posterman Chalkboard Art Project

First, John added the letters “BBQ” to the board with a light pencil mark. In our studios we like to use a Violet Zig Illumigraph marker because it can be removed by rubbing when you are done or by using a damp cloth. After, John uses a 30mm White Zig Posterman marker for the base, adding color on top of once it drys. You can use a hair dryer, or if it is a nice day like in this video it will air dry very quickly.

Zig Posterman Chalkboard Art Butchers BoardHe then uses a 6mm White Zig Posterman marker for the small lettering. Don’t worry about overlapping where you can use a black marker to clean it up after you are done. John then adds the colors Red, Orange and Yellow to the letters, adding a “firey” affect using a Big and Broad 15mm marker. Starting with red at the top, followed by orange and yellow. While it is still wet, he uses his finger to rub in the colors to smooth out the red to orange. Moving quickly, he adds the yellow and smooths it out into the orange which is also followed by white.

The next step he uses a broad chisel 6mm white and red marker to outline the letters and add affects. The next step, he uses a 15mm Red and White marker to make charcoal under the BBQ. John then uses the Violet Zig Illumigraph marker to add 5 sections of 2 lines for an outline of where he will list the items using a small paint brush, and alternate colors. Notice how he dabs the marker on a flat service to get the paint. To clean up the chalkboard John uses Black paint to make it as good as new!
