Step-by-Step Guide to Repairing Laminate with SeamFil Laminate Repair Paste

Repairing Laminate with SeamFil Laminate Repair Paste

Laminate surfaces can sometimes chip, crack, or scratch, but SeamFil Repair Paste is the solution to restoring the look of your laminate. Follow this simple guide to repair your laminate surface.

Materials You’ll Need To Repair Your Laminate Surface:

Step 1: Choose the Right Color

SeamFil is available in a wide range of colors. Choose the one that best matches your laminate surface for a seamless finish. ColorKam’s 2024 SeamFil Color Matching Guide will help you select the closest match.

  1. Find the number of your laminate and find it in the Color Matching Guide
    • SeamFil is available in 20 standard colors but can be made to match any color.

Tip: Having trouble finding the number of your laminate? You can check for the best match at your local home improvement store, or give us a call and our experts will assist you.

Step 2: Clean the Damaged Area

Before applying SeamFil, clean the damaged area thoroughly to ensure proper adhesion.

  1. Wipe the surface with a soft cloth dampened with SF-99 Solvent, which is specially mixed to work with SeamFil.
    • This will remove grease, oils, and dirt that may interfere with the repair.

Step 3: Prepare Seamfil Paste

  1. Squeeze a small amount of SeamFil Repair Paste onto a scrap piece of laminate or cardboard.
  2. Spread and work the SeamFil to thicken and allow solvents to evaporate.
  3. Add SeamFil Retarder to extend the mixing time. (optional)
  4. Mix in SeamFil 943 Clear Gloss or other colors following the 2024 SeamFil Color Matching Guide to perfectly match your laminate. (optional)

Step 4: Apply the SeamFil Paste

Once the surface is clean, it’s time to apply SeamFil.

  1. Using a putty knife, spread the SeamFil paste evenly across the damaged area.
    1. Ensure your putty knife is clean and undamaged to avoid damaging or scratching your laminate surface.
  2. Ensure the paste fills all cracks or chips.

Step 5: Remove Excess Paste

SeamFil starts to dry immediately, remove any excess material.

  1. Allow 5 minutes for SeamFil to cure after applying.
  2. Dampen a clean cloth or paper towel with SF-99 Solvent.
  3. Gently rub over the repaired area in circular motions to remove any excess paste surrounding the repair.

Step 6: Allow SeamFil to Dry

SeamFil will start to dry quickly and will achieve maximum strength after several days of curing time.

  1. Let the paste dry for 1 hour.
    • You can check if it’s dry by lightly touching it — it should feel firm and no longer sticky.
  2. Check for shrinkage or areas still showing damage. If so, you can repeat the process after 1 hour.

For larger repairs, allow more time for curing. We do not recommend attempting to make a repair larger than 1/4 of an inch in diameter.

Step 7: Final Cleaning

Once you’ve finished the repair, give the surface a final clean.

  1. Use a clean, damp cloth to wipe away any residual debris or dust

Step 8: Enjoy Your Restored Laminate

Your laminate surface should now look as good as new! SeamFil creates a long-lasting and durable bond, ensuring your repair will stand the test of time.
