A close look at ChalkFlex compared to Chalkboard Paint, Vinyl or Paper with a magnifying glass

Cohas Chalkboard Systems ChalkFlex products include quality material with a texture resembling antique chalkboards. They are perfect for use in homes, restaurants, bars, pubs and businesses!  This flexible but stiff plastic chalkboard is better than chalkboard paint, and other DIY chalkboard options on the market today.

If you have been thinking about using chalkboard paint, chalkboard vinyl or chalkboard contact paper, think again. Cohas ChalkFlex will not tear or stick to itself during installation. Thicker than other “chalkboard on a roll” options, ChalkFlex will not bubble, fold, crease or stick to where it should not when applying.

The plastic polymer is coated with an adhesive that removes when you want it to, not when you don’t expect it to. ChalkFlex is 100% nonporous, resulting in no staining of the surface under the installation. When applied over chalkboard paint it will cover up the mess made on your wall from chalk and chalk markers.

Better than Chalkboard Paint, Vinyl or Paper
When ready for a fresh look, just remove and replace; clean the surface and apply a new sheet of ChalkFlex to your wall, cabinet, appliance or door.

Plastic Chalkboard vs. Chalkboard Paint

Cohas Chalkboard System ChalkFlex is made from material that looks like a modern gray chalkboard. It will stick to any smooth surface and is easy to install. Sizes available for use on refrigerators, doors, cabinets, walls, and more. Used portrait or landscape ChalkFlex comes with no design on the surface. This provides you the entire area for your homemade lettering or illustration.

Kits come from 8×12 inches to 2×3 feet, or by the foot for larger installations.  All kits come with a wet-wipe liquid chalk marker. The premium marker features a chisel 6mm tip, perfect for making thick and thin chalk-like lines about 1/4-inches wide. The marker’s wet-wipe ink means it will remove easily with water. When you are ready to change your message or artwork, just use a damp cloth or sponge.

Easy and Safe

ChalkFlex is easy to clean and reuse, it is cut to size with a sharp knife when needed. It will stick to any smooth, clean surface. The material’s thickness and polymer makeup will prevent it from folding or clinging to itself, allowing for easier application.

Before installation, mounting surface must be clean, dry, and at room temperature forbest results. Begin installation by removing one corner of the backing and placing in desired position. Continuously apply pressure against the material surface while removing the backing. ChalkFlex is able to be repositioned immediately if needed. If left in place, material should be left to cure for at least 24 hours before attempting to remove. Some residue may be left behind, but will clean easily with soapy water. Safe on painted walls, doors, and other surfaces.

Safe in your home or business. Markers have the CE mark, meet Toy Safety Regulation EN-41, and bear AP Seal ASTM D4236.

  • Walls, even over chalkboard paint or chalkboard vinyl;
  • Signboards, coroplast, plastic inserts and sign panels;

Cohas ChalkFlex Chalkboard Application

ChalkFlex is easily applied to any smooth surface, even on a curved surface. Installation is not recommended for sharp or 90-degree corners. Before application, ensure the surface is clean, dry, and at room temperature for best results.

Begin installation by removing the paper backing from one corner of the material. Then place the material against the surface in the desired position. Continuously apply pressure to the face of the material and smoothing it over while removing the backing. Continue until all of the backing is off.


Chalkflex can be relocated immediately upon application. It is recommended that the material be moved within the first five (5) minutes of application. If left in place, it is recommended that it be left to cure for at least 24 hours before attempting to remove. Some residue may be left behind, but will clean easily with rubbing or soapy water.


The ChalkFlex surface is easy to clean and reuse. When using wet-wipe liquid chalk markers, simply wipe with a damp cloth. For waterproof markers, use Windex or an ammonia based cleaner. When using regular chalk “dustless” and “dust-free” chalk not recommended as the binders may scratch the board.

Do not use abrasive cleaners or chemicals that can scratch the material’s surface. Magic Eraser and other heavy cleaning products will ruin the surface of ChalkFlex.

Do not use heavy pressure when writing on the material.


Did you know most chalkboard paint has volatile organic compounds? Imported chalkboard vinyl is made with lead and a plasticizer called phthalate ester to make it flexible. Did you know this can leach out of your chalkboard? It is important to know, ortho-phthalate DHEHP has been banned in children’s products here in the United States since 2007.

All Cohas chalkboard products made from materials sourced right here in America.

Cohas ChalkFlex is eco-friendly & child safe: certified CPSIA (Consumer Product Safety Improvement Act) compliant, lead free and phthalate free.
