WonderPatch FLEX FAQs

How long must I wait before using something I have repaired with WonderPatch FLEX™?

You can use it right away. The space age adhesive we use utilizes mechanical bonding to link the adhesive into the microscopic irregularities in the surface of the item being patched. This mechanical bonding sticks very well right away. No need to wait.

Is there a best temperature for application?

WonderPatch FLEX™ is tolerant of a range of temperatures. For initial application, it is OK to apply the patches at temperatures as low as 60 degrees. If the patch and the surface that will receive the patch are not at least 60 degrees, try to heat the surfaces to be patched AND the adhesive side of the patches using a hair dryer or hot air gun before applying the patches. DO NOT USE A TORCH – IT WILL RUIN THE PATCH. Once applied, the patches are not sensitive to temperature at all.

If I must remove it, how do I get WonderPatch FLEX™ off?

Carefully follow the Directions. WonderPatch Flex™ cannot be removed without destroying the patch and possibly the patched item as well. You will first need to peel off the top surface of the patch by cutting through the adhesive foam using a flexible blade, a hot wire, an air chisel, or other similar method. You will leave behind on the patched surface some of the adhesive. You can grind that off with a porous abrasive disk or wheel or it can be removed using a special solvent. Call for details.

Are there any surfaces to which WonderPatch FLEX™ does not adhere well?

Nearly all rigid materials are a good match for WonderPatch FLEX™. Also, flexible materials are usually a good match for WonderPatch FLEX™ but some plastic items that feel "greasy" to the touch, are not a good match. Call us for more details if you are uncertain.

Can the WonderPatch FLEX™ be painted?

Yes, the WonderPatch FLEX™ can be painted by following these instructions.

WonderPatch FLEX™ Hole Repair Material comes from the factory with TWO top layers. The outermost layer is shiny and non stretchable. It is intended to stay in place while applying the patch and it is not paintable.

To paint the patch, the shiny outer layer must be removed to expose the dull finished layer designed to hold paint. We do not recommend removing the shiny outer layer before applying the patch because doing so will allow the patch to stretch and flex and actually make it difficult to apply evenly.

  1. After applying the patch, carefully remove the shiny outer layer. Once you get it loosened at a corner, it will easily peel off. Pick up the shiny outer layer at a corner by using a small knife or a fingernail at the edge of the patch. Alternatively, you may find it easier to begin by pricking the outer layer using a pointed object and then flicking the corner up.
  2. Mask the area surrounding the patch to avoid having paint over-spray onto the surrounding area.
  3. No special preparation of the dull paintable surface is needed. Just be sure not to contaminate it with foreign material before painting.
  4. Paint the patch surface with high quality aerosol paint using several light coats rather than a heavy coat.
  5. Allow the paint to dry thoroughly.
