Marvelseal

== Description ==
[Ludlow Corporation] A registered trademark for a barrier material made from multiple film layers laminated together. Marvelseal is made with 
thumb
 sandwiched between nylon and polyethylene forming a strong, waterproof, vaporproof, and flexible film. Originally made for military applications, Marvelseal 360 found its way into museums and for use sealing wooden packing crates, display cases, and storage shelves since 1980. It has also been used to create air-tight sealed enclosures for pest eradication. Paint does not adhere to Marvelseal very well but the surface can be covered with fabric or Dibond. A foil back sealing tape is available to cover staples and pin holes.

The heat from the iron seals the Marvelseal to the wood and provides a vapor barrier. Application works best with iron set at highest heat level. Keep iron moving otherwise it will get stuck on the Marvelseal and tear it.
For best results, the entire piece of wood must be completely covered with Marvelseal. If the Marvelseal tears, simply cut a small piece of Marvelseal and iron it onto the torn spot.
