Select from the following choices. 1. Gesso The store-bought product is the easiest option. Here are some common brands available on 2. Acrylic Paint Acrylics are inexpensive and easy to use.

Tips to Prevent Warping or Curling Moisture is the leading cause of warping or curling. You’ll want to attempt everything you can to keep from damaging the material if you’re going to create long-lasting art. The following includes a few tips to keep the painting safe from warping or curling:

  • Don’t oversaturate the paint.

  • Keep all moisture from the material.

  • Avoid humidity.

  • Use gesso to prime before painting.

  • Allow coats to dry before including more.

  • Work in a dry environment.

  • Never use watercolors or overly wet paints.

  • Use a double or triple-wall, thick corrugated cardboard.

Even if you follow these tips carefully, the board may still warp and curl. But you might be able to fix the issue.

How to Fix Warped Cardboard Cardboard is a fantastic painting material, but it’s challenging to deal with when it gets too wet. If you accidentally use too much paint or printer, the cardboard may warp or curl. You can fix it if the damage isn’t too severe. Use the following step-by-step instructions to mend your painting.


  • Spray bottle

  • Water

  • Weights or heavy objects (books, furniture, metal tools, etc.)

Step 1: Completely Dry Dry the Daisybox lid and base separately until they are completely moisture-free. Step 2: Spritz with Water To reshape the material, start by rehydrating. Grab a spray bottle and moisten the cardboard. Never dip the board into water or over-soak the material. If you get it too wet, the pulp will tear away from the base. Lightly spritz the board. Step 3: Load it Up Next, set the lid and base on a flat surface with the curls facing upwards. Lay a flat piece of plywood over the board and place your weights or heavy objects on the area to keep the cardboard flat. Books make an excellent tool, but anything heavy should weigh it down enough. Let your art sit to dry in this position for between 24 hours and 3 days. When the cardboard is completely dry, you can lift the panels. The painting should be flat and free of any warping or curling.
