How to Prevent Paper Curling When Laminating with Resin

Why Does Paper Curl Under Resin?

Paper absorbs moisture from resin, which can lead to swelling and distortion, commonly resulting in unsightly curling. Types of paper, resin volume, and room humidity all make a difference—thin or unsealed sheets are most vulnerable to moisture absorption.

Step-by-Step: Keeping Paper Flat

• Seal the Paper First: Before pouring resin, spray both sides lightly with an acrylic sealer or carefully brush on a thin coat of clear-drying glue, allowing each side to fully dry. This forms a moisture barrier and helps preserve your artwork’s clarity.
• Secure Paper to the Work Surface: Tape down the edges or use a very thin layer of glue to hold the sheet firmly in place. Make sure the paper is entirely flat with no wrinkles or air pockets.
• Apply Resin Evenly: When ready, pour a suitable resin in a thin, even coat—options such as “Art Pro” Clear Epoxy Resin are designed for clear, smooth finishes. Avoid over-soaking the surface at once; more than one thin layer may be needed for best results.

When This Matters Most

Preventing curling is vital when laminating original artwork, printed photos, or decorative paper, especially if the finished piece will be displayed or gifted. Attention to sealing and securing is key to achieving a clear, bubble-free result.
