How to apply Heldite:

  • Apply one coat to each component and allow the compound to become tacky.
  • Close the joint. For screwed joints, apply one coat to each mating thread and screw up immediately.
  • For absorbent materials such as cork, apply one coat to each side of the washer or gasket and leave for a moment to soak in.
  • Repeat the first step for a second coat. Allow to become tacky before closing the joint.

To work effectively, Heldite needs to dry out as this is a solvent based product, which can take between 20mins and 8hrs.

Hemp or PTFE tape is recommended if there is any doubt of the quality of the screw threads or if the joint is to be put under immediate pressure. Its recommended to coat the threads with Heldite before using Hemp or PTFE. This will support the Heldite jointing as it sets.

However, it is advisable to allow the compound to dry/set completely before putting the joint under full pressure or shifting levels and stresses.
