MultiSeal Preparation Guide


Preparing the surface where Silicone is present:

If the surface already has silicone in place then all traces of silicone must be removed - Multiseal will not adhere to the surface if silicone is present. Silicone can remain present even if you can't physically see it.

  1. Remove as much silicone as you can with a scraper or alternative
  2. Once the surface is visually free from silicone or traces remain use the Sili-KIll by applying liberally to the surface and leave for 20-30 minutes, following the instructions on the bottle
  3. Once all traces of Silicone are removed use a MultiSeal preparation wipe to clean the surface – you must ensure the surface is completely clean and bone dry before moving onto the next step
  4. Then use the alcohol wipe, again leave to dry, then wipe with a clean dry cloth
  5. Try a small test piece of Multiseal along different sections of the surface to check it will adhere - you are looking for an immediate grab.
  6. If required repeat step 2 once or twice until MultiSeal adheres

Installation of MultiSeal to a clean surface or after silicone removal:

  1. Clean the surface with general household cleaner to remove the dirt and debris
  2. Dry thoroughly with dry cloth, ensuring the surface is bone dry before proceeding
  3. Wipe the surface with a MultiSeal preparation wipe
  4. Wait for the surface to completely dry.
  5. Then use the alcohol wipe, again leave to dry, then wipe with a clean dry cloth
  6. Measure the length of the MultiSeal you will need and cut the MultiSeal to length, oversize slightly for cutting, then offer up to the wall to measure exact and cut using the tool provided in the installation kit
  7. Where mitred joints are required use the mitre blocks, push the MultiSeal into the block and cut cleanly along the edge

    (you may have to trim the harder plastic at the base to improve the mitre)

  8. Then apply the MultiSeal, pushing back and down hard to ensure it adheres - if you make a mistake you can peel it back and try again, (if performed immediately). As with any adhesive the more times you re-apply it the less effective it can be.
  9. Once MultiSeal is in place, apply hard pressure to the MultiSeal

    (example - end of a wooden spoon)

  10. Use the sealant glue to seal any mitred corners

    (the nozzle needs cutting prior to use)

  11. Multiseal adhesive takes 2hrs to begin to cure and takes 72hrs to completely cure.

CAUTION: Multiseal works best on completely clean and bone dry flat surfaces, if you try to apply Multiseal to a surface where there has previously been dirty or wet conditions you may find it difficult to apply MultiSeal.
Deep grout lines may require filling prior to installation of MultiSeal.
