• Elevate Waterblock Sealant is Butyl based & very stringy & sticky - take significant care when applying.

  • Can Waterblock Sealant repair or seal EPDM Rubber?
    No, Waterblock sealant is not designed to be used as an external caulk. It provides a long-lasting waterproof seal when under compression. This can include under your EPDM & a secured termination bar - or behind a jubilee clip, which provides the seal when tightened.
  • How do I clean excess Waterblock which bleeds out under compression.
    Waterblock is Butyl based, so very sticky & stringy, so take care when applying. When removing excess, be sure to use gloves and a disposal scraper or tool to neatly pull away excess sealant.

Notes on the delivery of Elevate EPDM:

If you order EPDM with your items, the rubber will be delivered rolled up for ease of transport. As a result there may be some fold creases and wrinkles - this is normal. To remedy this, the EPDM should be laid to rest, or settle, for a minimum of 1 hour. In colder temperatures, the light use of a heat gun (not a naked flame) can be used to settle the rubber. Don't overheat or touch directly.

Starting your project:

We advise not booking in or arranging an installation team to begin works before the goods have been delivered & inspected. Delays or order mistakes are rare, but can happen. We can't be liable for any costs as a result from delayed or incorrect delivery or items.
