Preparing the Cardboard for Painting
Cleaning the Cardboard
Before painting, it’s crucial to thoroughly clean the cardboard to remove any dirt, dust, or oils that could interfere with paint adhesion. Use a damp cloth and mild detergent to gently wipe down the surface, moving in a circular motion. Avoid using abrasive sponges or scourers, as they can damage the cardboard. Allow the cardboard to dry completely before proceeding.
Priming the Cardboard
Applying a coat of primer to the cardboard is essential for creating a smooth, even surface for painting. Primer fills in the porous fibers of the cardboard, providing a better foundation for the paint. Choose a primer specifically designed for cardboard, such as acrylic primer or gesso. Use a brush or roller to apply a thin layer of primer, ensuring even coverage. Allow the primer to dry completely before painting.
Sanding the Cardboard
Sanding the cardboard after priming helps create a smooth surface that is less likely to absorb paint unevenly. Use fine-grit sandpaper (120-grit or higher) and lightly sand the primed surface in a circular motion. Remove any sanding dust using a soft brush or damp cloth.
Sealing the Cardboard
Before painting, it’s recommended to seal the cardboard to prevent moisture penetration and preserve its durability. Apply a thin layer of clear sealant, such as acrylic sealant or polyurethane, using a brush or roller. Allow the sealant to dry completely before painting.
