Fiberlock Serpi Wet-Wrap 'N' Seal rolls are recommended for repairs to deteriorating, crumbling, or damaged asbestos insulation.  Wet-Wrap 'N' Seal Pipe Repair Wrap can be applied prior to asbestos encapsulation with Rewettable Canvas Pipe Lagging and/or Fiberlock Lag-Kote Coating.  Fiberlock Serpi Wet-Wrap ‘N’ Seal is a permanent asbestos insulation repair system which can be applied quickly and easily.  Once dry, this rewettable pipe lagging permanently retains its strength, shape, and form.  Wet-Wrap 'N' Seal Asbestos Wrap can be spiraled around the damaged insulation to create a solid and secure casting prior to encapsulation.  Fiberlock Wet-Wrap 'N' Seal can be used in conjunction with Fiberlock ABC Fiberspray when sealing off ends and edges of asbestos pipe insulation.

Roll Size: 4" Wide x 9ft Long

**This asbestos exhaust wrap is also available in a 6" Width.


  1. Put room temperature water into a clean 5 gallon pail or bucket. Fiberlock Wet-Wrap 'N' Seal Asbestos Wrap contains a plaster of paris and synthetic resin combination. Use of skin protection or gloves is recommended.
  2. Hold loosely and submerge one asbestos pipe wrap tape roll at a time into the water bucket for 5 seconds. Keep thumb under edge of Wet-Wrap ‘N’ Seal to avoid difficulty in finding starting end after squeezing.
  3. Remove and squeeze with twisting motion to wring out excess water, keeping thumbs under starting end.
  4. When applying overlap each layer by 50%, smooth each overlap turn of Wet-Wrap ‘N’ Seal Pipe Repair Wrap into the layers below, molding carefully to the contour, forming a solid, well-fused covering.
  5. Apply Rewettable Canvas Pipe Lagging over the Wet-Wrap 'N' Seal once fully dried.
  6. For a clean and finished appearance, coat with Fiberlock Lag-Kote Coating.

    Rolls are not as long as I had anticipated. I was duped to believe I was getting (5) 9ft. long rolls. Only to find that the 5 rolls equal @ 15 ft. in total. Other then that, the product appears to be a fantastic product. The rolls are just too darn small - at most, each roll is only @ 3 ft in length. Too bad for me I guess. I already used them - but was hoping to do more. I was lead to believe I would get 45 ft.

    *Richard, hello the rolls themselves are 9ft long but once wrapped over the insulation you will get much less than 9 linear feet of coverage. I am assuming that is the issue. We will reach out to you to discuss further ~ BIP

    I used this product to repair some damaged lagging in my basement, and it worked flawlessly. It was easy to trim and shape . Highly recommend this stuff.

    Relatively smalls rolls are easy to work with and maneuver which is good since they dry up real quick.

    So far it is very easy to work with and dries fast and hard. I feel I am saving a lot of money doing this project myself.

    Worked as described

    Used rolls along with yards of lagging and Lag Kote II. Good to have all 3 items, depending on what areas you need to cover/reach. With these narrow roles, just be careful not to bunch together after dipping into water.

    Excellent. I bought some for our contractor and he was pleased with how easily it went on and how quickly it dried (2 min. he said). Looks like new. Literally. It does take quite a build out, so I am back ordering another batch, but it depends obviously on how damaged your pipes are. Excellent product. Affordable.

    I am using this to cover / repair bad crumbling areas
    of my asbestos coated heat ducts before wrapping with the Rewettable Canvas Pipe Lagging. When this product hardens it feels pretty sturdy and then it's even stronger after wrapping with the canvas pipe lagging. I like this product but it is a little tricky for me to use because when I dip it in water to get it wet it takes on the consistency of wet toilet paper. I have had better luck with using shorter pieces and wrapping it around the duct dry and then wetting it down with a spray bottle.
