Subject: Pooled EternaPrime could dissolve the adhesion of the granule.
- Remove oxidation from roof surface.
- Pre-treating with EternaPrime is preferred. In the event you choose not to use EternaPrime on the entire installation, use
EternaPrime on areas where contact is difficult (inside bends on standing seams, etc).
- Roof must be dry. When covering seams if water is trapped in the seam, this must be dry before proceeding.
Trapped water can turn to steam - releasing the sealant at that point, setting up a chain reaction. More water can now migrate
under the now un-fused area..
- Do not leave gaps at the end of a run open. This can happen when the end is changing elevations, as when going over a seam
or clete. In these situations, use EternaBond DoubleStick to start the run or seal the ends with a good, non-silicone caulking.
- Difficult transitions are easily remedied by cutting and folding the EternaBond tape, as if wrapping a package.
- Close all “fish mouths” by cutting and folding the mouth. Crushing the fish mouth down is not recommended.
- Ditto large air pockets
- WebSeal is the preferred product for metal roofs; however it requires a roof coating to complete the installation. When a roof
coating is not speced or inconvenient, RoofSeal and A-Seal work well and do not require a roof coating. Remember that they are less
conformable than the woven backed WebSeal, so take the time to do a tight installation. Do not stretch these backings to force
contact. Gently lay the tape into the shape, rubbing as you go to activate the fusing process. Where a tent occurs in a critical area
- like along the edge of the tape, cut it with a razor and fold it down, adding a 2nd piece if necessary.
