Repairing Your Poly Perimeter or Skin Base

During normal wear and tear, or in the case of a bump on the head, it’s possible for the delicate base of your hair system to acquire a tear or hole. This guide will instruct you on the proper way to repair a tear or hole in your skin base or poly perimeter using the Liquid Poly Repair Kit. Please be aware that a repair is a temporary solution, and only feasible for small holes or tears. Be sure to order a new hair system as soon as you can, and use your backup hair system in the interim, if the hole does not lend itself to repeated patching.

If you’re uncomfortable doing your own repair, remember you can always send it to us and we’ll be happy to do it for you.

Before you begin

The method detailed in this guide is recommended for repairing tears in skin bases and poly perimeters. Clean your base following the usual procedure, and allow it to dry completely. Then proceed with the steps below.

Step 1: Secure and prepare your hair system

With the underside of the base facing up, use T-pins to secure your system to a Styrofoam head. Place the T-pins around the perimeter of, but not through, the skin or poly perimeter. Turn the pin so that the top part overlaps the edge of the base to secure it.

Using your hands, smooth and flatten the tear on the base to the best of your ability.

Clean the tear area with acetone.

If the hair is likely to get in the way of the repair area, tape it down to the head with surgical tape.

Step 2: Cut and apply the tape

Using the tape included in the Liquid Poly Repair Kit, cut a piece slightly larger than the tear.

Place the tape over the hole or tear, and firmly press or rub it on to the base material.

Remove the tape backing.

Step 3: Apply the liquid polyurethane

Next, brush one very thin layer of the liquid polyurethane over the tape. Be sure to brush the liquid poly past the edges of the tape.

With each new attachment, remove the tape patch before you clean your base, and apply a new patch after the base has been cleaned.

Step 4: Let the repair dry

Dry the patch with a hair dryer, on the lowest setting. Allow the repaired area to fully air dry overnight.

Before you apply adhesive to the base, make sure the liquid polyurethane is no longer tacky.

You can also use liquid polyurethane without tape to repair the damaged area. Keep in mind that applying liquid polyurethane directly to a skin base will cause the repaired area to become slightly bumpy.

Step 5: Prepare for attachment

If the patch is in an area where you normally apply adhesive, you can apply bonding tape or liquid adhesive over it once it’s fully dry.
