The Best Ways to Seal Paper for Your Projects (2024)

If you're planning to use resin to cover or embed paper in a project, it's generally a good idea to seal the paper first. Sealing the paper will help to prevent the resin from soaking into the paper and causing it to wrinkle, distort or become discolored.

What is resin paper

Resin-coated paper involves applying a layer of epoxy resin onto paper, as the name suggests. This process has several benefits. Resin is a robust material that can not only augment the appearance of your artwork but also offer substantial protection.

Any paper type can be used with resin as long as it is sealed beforehand. Your resin-based artwork can incorporate photographs, cardboard, stickers, tissue paper, book pages, and more. Adding resin to your paper art adds depth and gives it a beautiful finish.

Why do you need to seal paper for resin

Paper is porous, which has small spaces or holes in its surface that allow air, water, or other substances to pass through.Sealing paperbefore applying resin can provide several benefits.

1. Prevents bleeding: Unsealed paper can absorb the resin, causing the ink or pigment in the paper to bleed, resulting in an unsightly and blurry finish.
2. Enhances adhesion: Sealing the paper creates a smooth surface that allows the resin to adhere better, resulting in a stronger bond between the paper and the resin.
3. Avoids air bubbles: Sealed paper helps to prevent air bubbles from forming between the paper and the resin, which can mar the final product's appearance.
4. Preserves color and texture: Sealing the paper helps to preserve the original color and texture of the paper, as the resin will not penetrate the paper's fibers and alter its appearance.

How to seal paper for resin

Spray Sealer

You can use a spray sealer to coat the paper and create a barrier between the paper and the resin. Spray sealers come in various finishes and can be found at most craft stores.

1. Ensure that the paper is clean and free from any dust or debris.
2. Shake the spray sealer can well before using it.
3. Hold the can at a distance of 6-8 inches from the paper and spray a light coat over the entire surface. Be sure to keep the can moving to avoid creating any drips or pools of sealer.
4. Wait for the first coat to dry completely, usually about 30 minutes to an hour, depending on the brand of sealer and environmental conditions.
5. Apply a second coat of sealer in the same manner as the first.
6. Allow the second coat to dry completely before applying the resin.

Mod Podge/Decoupage Glue

Mod Podge is a water-based sealer, glue, and finish that can be used to seal paper before applying resin. Simply brush a layer of Mod Podge onto the paper and allow it to dry before applying resin.

1. Choose the paper you want to seal for resin. Make sure it is completely dry and free of any wrinkles or creases.
2. Cover your work surface with wax paper or a silicone mat to protect it from any spills or drips.
3. Using a foam brush or paintbrush, apply a thin layer of Mod Podge to the front side of the paper. Be sure to apply the Mod Podge evenly and cover the entire surface of the paper.
4. Allow the Mod Podge to dry completely. This may take 30 minutes to an hour depending on the thickness of the layer and the humidity in your environment.
5. Once the Mod Podge is dry, flip the paper over and repeat step 3 on the back side of the paper.

P.S. Any glue that dries clear will work.

Heat-sealing

You can use a heat-sealing method to melt a layer of wax or plastic onto the paper, which will create a barrier between the paper and the resin. This method is commonly used in bookbinding and can be done with a heated tool or an iron.

1. Cut a piece of parchment paper slightly larger than the paper you want to seal.
2. Place the paper between the two layers of parchment paper, making sure that the parchment paper covers both sides of the paper.
3. Preheat the iron to a low or medium setting, without steam.
4. Iron the parchment paper, pressing down firmly and slowly moving the iron over the entire surface of the paper. Make sure to apply heat evenly to the paper.
5. Check the paper to ensure it's fully sealed by gently pulling at the edges.

Tape

Keep in mind that the tape method is not a foolproof way to seal paper for resin. It's important to use enough tape to cover all the edges completely and to apply resin carefully to avoid any leakage. You can follow these steps:

1. Cut a piece of tape that is slightly larger than the paper you want to seal.
2. Place the paper on a flat surface and carefully lay the tape over it, making sure there are no air bubbles or wrinkles.
3. Smooth the tape down firmly with your fingers or a flat tool like a credit card to ensure it adheres to the paper.
4. Trim any excess tape from around the edges of the paper using scissors or a craft knife.
5. Repeat this process on the other side of the paper if necessary.
6. Once the paper is fully sealed with tape, you can pour resin over it and allow it to dry according to the resin manufacturer's instructions.

Laminating Sheets

Sealing paper for resin by laminating sheets is a great way to protect the paper from getting damaged or discolored by the resin.Here are the steps you can follow to laminate the paper:

1. Place the desired size and shape paper on a flat surface and cover it with a piece of clear adhesive laminating sheet that is slightly larger than the paper.
2. Use a squeegee or your fingers to smooth out any bubbles or wrinkles in the laminating sheet, starting from the center and working your way outwards.
3. Trim the excess laminating sheet using scissors or a craft knife, leaving a small border around the paper.
4. Repeat the process on the other side of the paper if you want both sides to be laminated.
5. Now, you can use the laminated paper in your resin project. Simply apply the resin to the laminated paper, making sure to spread it evenly and remove any bubbles.

What resin is the best to seal paper

Epoxy resin is a popular choice for sealing paper because it is clear, glossy, and durable. It can provide a strong protective barrier that can help prevent the paper from tearing, fading, or getting damaged. It's also heat-resistant and waterproof, making it a great option for items that will be exposed to moisture or heat.Ultimately, the best resin to use for sealing paper will depend on your specific needs and preferences, as well as the type of paper you are working with.
