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.

You will need to use a high grade silicone remover, we recommend using Sili-Kill available through our website.

Silicone can remain present even if you cant physically see it.

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

  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 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 needs be repeat step 2 once or twice until MultiSeal adheres

Preparing the surface for a clean installation or after silicone removal:

  1. Clean the surface with general household cleaner to remove and 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 a minimum of 5 minutes for the surface to completely dry.
  5. Then use the alcohol wipe, again leave to dry, then wipe with a clean dry cloth
  6. Use a clean dry cloth to ensure the surface is dry
  7. 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
  8. Where mitred joints are required use the mitre blocks, push the Multiseal into the block and cut cleanly along the edge
  9. 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.
  10. Use the sealant glue to seal any mitred corners
  11. Multiseal adhesive takes 2hrs to begin to cure and takes 72hrs to completely cure.
