Application Instructions for Everflex JS

Follow these instructions to achieve optimal results when applying Everflex JS:

  1. Ensure that all joints are filled to the required depth with Adhefoam backer rod or bond breaker tape before applying the sealant.
  2. Use a spatula to tool off the sealant immediately after application, ensuring a flat and non-concave finish.
  3. Prepare the joint surfaces by thoroughly cleaning them, removing any dirt, grease, laitance, loose particles, or contaminants.
  4. For most substrates, priming is not necessary. However, it is recommended to conduct adhesion testing for suspect surfaces.
  5. Consider joint design by allowing for approximately ±25% movement of the original joint width. Everflex JS can accommodate movement up to ±50%.
  6. The recommended minimum depth of sealant is 6mm, with a maximum of 10mm, regardless of the joint width.
  7. There is no maximum joint width, but testing is recommended for very wide joints to ensure sagging does not occur.
  8. Avoid placing joints deeper than a 2:1 ratio to prevent excessive sealant consumption.
