How To Apply  

Application Guide

  1. Surface Preparation: Ensure all surfaces are structurally sound, dry, and clean from dust, oils, and contaminants. For porous substrates, priming with Everflex Supaprime is recommended.
  2. Application: For joints, apply Hi-Flex Construction using a cartridge gun. Cut the nozzle at a 45-degree angle and push the sealant ahead of the nozzle to ensure full contact with the sides of the joint. For bonding applications, cut the nozzle at a 90-degree angle, ensuring a triangular bead is applied. Compress the surfaces together to achieve adhesion.
  3. Curing Time: The sealant skins in approximately 10 minutes, and cures at a rate of 3mm per 24 hours. Cure times may vary depending on atmospheric conditions and substrate porosity.
  4. Clean-Up: While the sealant is wet, clean tools with Xylene. Once cured, mechanical removal is necessary.
Limitations  

Limitations

  • Not suitable for long-term water immersion or swimming pools
  • Cannot be used in totally confined spaces due to the need for humidity curing
  • Avoid use with chlorine exposure or in aquarium applications
  • Not recommended for structural glazing or mirror bonding
  • May cause discolouration on copper and brass surfaces
  • Avoid using on bituminous surfaces or where compounds may leach solvents
