2. Setup and Preparation
Proper preparation is crucial for successful vinyl application. Ensure your workspace is clean, dry, and free of dust.
Required Tools:
- Vinyl cutting machine (e.g., Cricut, Silhouette)
- Cutting mat (if required by your machine)
- Weeding tool
- Transfer tape (medium tack recommended for ORACAL 631)
- Squeegee or application tool
- Scissors or craft knife
- Clean cloth or rubbing alcohol for surface preparation
Surface Preparation:
- Clean the Surface: Thoroughly clean the application surface with rubbing alcohol and a clean cloth. This removes dirt, grease, and residues that can prevent proper adhesion.
- Dry Completely: Ensure the surface is completely dry before applying vinyl. Any moisture can compromise the adhesive.
- Smooth Surface: For best results, apply vinyl to smooth, non-porous surfaces.
3. Operating Instructions (Application)
Follow these steps for cutting, weeding, and applying your ORACAL 631 vinyl design.
Step 1: Cut / Plot Your Design

- Load the ORACAL 631 vinyl into your cutting machine, ensuring the matte side is facing up (liner side down).
- Adjust your machine's settings for matte adhesive vinyl. A test cut is recommended to find the optimal blade depth and pressure.
- Cut your design. Ensure the cut goes through the vinyl layer but not the paper backing.
Step 2: Peel / Weed Excess Vinyl

- Carefully remove the excess vinyl from around your cut design using a weeding tool. Start from a corner and slowly pull the vinyl away.
- Remove any small inner pieces from letters or intricate designs.
Step 3: Apply Transfer Tape

- Cut a piece of transfer tape slightly larger than your design.
- Place the transfer tape over your weeded vinyl design, sticky side down.
- Use a squeegee to firmly rub over the transfer tape, ensuring the vinyl adheres to it. Start from the center and work outwards to remove air bubbles.
- Slowly peel the transfer tape away from the vinyl backing paper at a 45-degree angle. The vinyl design should lift with the transfer tape. If parts don't stick, lay the tape back down and rub again.
Step 4: Apply Vinyl to Surface

- Carefully position the transfer tape with your vinyl design onto your prepared surface.
- Once positioned, use the squeegee to firmly rub over the transfer tape, applying pressure to adhere the vinyl to the surface. Work from the center outwards.
- Slowly peel the transfer tape away from the vinyl design at a 45-degree angle. If the vinyl lifts, lay the tape back down and rub again.
- After removing the transfer tape, rub over the vinyl design one last time with your fingers or a soft cloth to ensure full adhesion and remove any small bubbles.
4. Maintenance and Care
To ensure the longevity of your ORACAL 631 vinyl applications, follow these care guidelines:
- Cleaning: Clean vinyl surfaces with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals, as these can damage the vinyl or adhesive.
- Indoor Use: ORACAL 631 is primarily designed for indoor applications. While it can be used for temporary outdoor projects, prolonged exposure to harsh weather conditions (extreme temperatures, direct sunlight, heavy rain) may reduce its lifespan and removability.
- Storage: Store unused vinyl rolls in a cool, dry place away from direct sunlight. Keep the roll upright or suspended to prevent flattening or damage to the edges.
- Removal: When removing, peel the vinyl slowly at a sharp angle. Gentle heat (e.g., from a hairdryer) can assist in removal and minimize adhesive residue, though ORACAL 631 is designed for clean removal.
5. Troubleshooting
Here are solutions to common issues encountered during vinyl application:
- Vinyl Not Cutting Properly:
- Solution: Adjust blade depth and pressure settings on your cutting machine. Perform a test cut on a small piece of vinyl to find the optimal settings. Ensure your blade is sharp and clean.
- Vinyl Not Sticking to Transfer Tape:
- Solution: Ensure you are using a medium-tack transfer tape suitable for ORACAL 631. Firmly rub the transfer tape onto the vinyl with a squeegee before peeling. Peel the transfer tape slowly at a sharp angle.
- Vinyl Not Sticking to Application Surface:
- Solution: Thoroughly clean and dry the application surface before use. Ensure the surface is smooth and non-porous. Apply firm pressure with a squeegee during application.
- Air Bubbles Under Applied Vinyl:
- Solution: Apply the vinyl slowly and evenly, working from the center outwards with a squeegee. For small bubbles, you can gently prick them with a fine needle and smooth them out.
- Vinyl Peeling Off Edges:
- Solution: Ensure edges are firmly pressed down during application. Avoid cleaning the applied vinyl for 24-48 hours to allow the adhesive to fully cure.
